Revenue-first optimisations

Focus on conversion value, CAC reduction, and MER accuracy over raw traffic.

Tracking & attribution clarity

GA4 + server-side tracking and clean dashboards for reliable revenue attribution.

Tested, scalable roadmap

Audit → Build → Test → Scale cycle that prioritises high-impact wins.

What are website-optimization-services and why they matter

Website-optimization-services combine front-end performance, conversion rate optimisation (CRO), analytics instrumentation, and UX improvements to turn more visitors into measurable revenue. For Shopify and WooCommerce stores, B2B SaaS landing pages, and service sites, the goal is not just more traffic but higher revenue per visitor and cleaner attribution for accurate decision-making.

A revenue-first approach

Prebo Digital designs website-optimization-services to prioritize profit and attribution clarity. Improvements target faster load times, clearer funnel flows (TOF → MOF → BOF), and server-side tracking to close gaps between platform-reported conversions and your true return. Learn how our overall strategy connects to broader services on our Services overview.

Core components included

  • Site speed and Core Web Vitals tuning
  • Conversion funnel audits and A/B testing
  • GA4, server-side tracking and tag governance
  • Checkout UX and cart friction removal for Shopify/WooCommerce
  • Attribution modeling and revenue-level reporting

Each engagement begins with a technical and business audit that surfaces high-impact wins. For example, a $100,000/month ecommerce store with a 1.2% checkout conversion rate could see a meaningful increase in monthly revenue by improving conversion and reducing load times - estimates depend on testing and implementation specifics.

How this fits into a growth system

Website-optimization-services are one pillar of a structured growth loop: Strategy → Build → Test → Scale → Report. This is aligned with the agency-level approach described on our homepage, and it ensures improvements are measurable and repeatable across channels like Google Ads, Meta, and TikTok.

Initial deliverables in a typical engagement

  • Technical site audit & prioritized backlog
  • Conversion funnel map (TOF/MOF/BOF) with test plan
  • GA4 and server-side tracking setup with clear attribution
  • UX fixes and speed optimizations staged for deployment

Implementation, measurement, and expected outcomes

After the audit, the build phase focuses on measurable changes: code-level performance tweaks, checkout UX enhancements, and tracker hardening (GTM + server-side). Tests are designed for statistical validity and business impact, prioritising revenue per visitor and CAC reduction over vanity metrics.

A sample optimization roadmap

Phase Focus Outcome
Audit Performance, funnels, tracking Prioritised backlog
Build Code fixes, checkout UX, GTM Faster pages, reduced friction
Test & Scale A/B tests, attribution verification Revenue improvements, validated lift

Example US scenario: a mid-market Shopify store running $60,000/month in ad spend with a 2.0% conversion rate may find that a 15-30% relative uplift in checkout conversion (from targeted UX + speed work) meaningfully lowers CAC and improves margin. These figures are estimates and results vary by industry and traffic mix.

Reporting and attribution clarity

We deliver revenue-focused dashboards and clean attribution using GA4, server-side tracking, and controlled experiments. That reduces reliance on platform-reported conversions and gives your growth team a single source of truth for MER and LTV analysis. Read more about our data-driven approach on our About page.

Partnership model and next steps

Website-optimization-services can be scoped as a short-term technical engagement or an ongoing retainer that pairs CRO, analytics, and development. Scope typically includes clear inclusions/exclusions in the proposal and a roadmap tied to revenue KPIs. If you want a growth-focused evaluation, you can request a growth audit or book a free strategy call through our contact page.

Practical note: small technical fixes (image optimization, critical CSS, cache policies) often produce quick performance wins, while CRO experiments validate higher-value UX changes before full rollout.

eCommerce Marketing Strategies: The Myths, the Facts, and the Playbook

Why Most eCommerce Marketing Advice Is Backwards (Start Here) Most eCommerce marketing strategies are built on advice that sounds smart but quietly destroys margin. The standard playbook - scale ad spend, add more channels, trust platform-reported ROAS - works fine until your contribution margin starts shrinking while top-line revenue looks healthy. By the time founders notice, they have already funded a year of unprofitable growth. This article flips the sequence. Instead of starting with tactics, we start with the myths that mislead US DTC and B2B commerce teams, then replace them with facts drawn from platform documentation, primary research, and the diagnostic work behind Prebo Digital’s services . Then we map those facts to a sequencing playbook that respects your store type, price point, and existing data infrastructure. Most “growth” problems are measurement problems wearing a tactics costume. Fixing tracking first usually changes which tactics look worth funding. Myth 1: Scaling Ad Spend Scales Revenue The belief that revenue scales linearly with spend ignores diminishing marginal returns, rising CAC, and the fact that online still represents a minority of US retail. According to the US Census Bureau, eCommerce sits at roughly 16-17% of total US retail sales and moves only 0.1-0.3 percentage points per quarter. That changes the strategic question: you are not fighting for a blank-slate market. You are fighting for share of wallet in a largely offline economy, where repeat purchase behavior compounds faster than new-customer acquisition. There is no single federal eCommerce privacy law in the US, so data signals vary region to region. That fragmentation means more spend does not automatically mean more measurable revenue; without server-side tracking, budget often flows to the channels that simply report the best, not the ones that actually increment. The MER, CAC, and LTV Baseline You Need Before Spending More Before increasing budget by any percentage, lock down three numbers. Without them, every scaling decision is a guess. Directional benchmarks: new-customer acquisition typically costs around 5x what it costs to retain an existing customer, and repeat customers often drive 40%+ of DTC revenue from a much smaller share of the base. Treat these as ranges, not guarantees. 5x Directional range for new-customer acquisition cost vs. retention cost in typical US DTC MER (Marketing Efficiency Ratio) = total revenue ÷ total ad spend. Tracked weekly, not monthly. Blended CAC = total acquisition + retention cost ÷ new customers acquired. Contribution margin per order = AOV - COGS - shipping - payment fees - ad cost attributable to that order. If contribution margin per order is flat or falling while revenue grows, you do not have a scale problem. You have a margin problem, and more spend will make it worse. Myth 2: Retention Is a Later-Stage Concern Retention is treated as an afterthought in most paid-media-led strategy decks. In practice, it is the first lever that should be audited. Email and SMS marketing - Klaviyo remains the default in the US Shopify ecosystem - consistently returns more revenue per dollar than paid acquisition when flows are properly built. Flow emails (welcome, abandoned cart, post-purchase, win-back) typically outperform one-off campaigns on revenue per send. The Retention Math That Quietly Compounds Revenue Consider a store with 8,000 customers. If 35% are repeat buyers at a R1,200 average order value (AOV), that base drives roughly R3.36 million in annual repeat revenue before any upgrade or bundle effect. Adding a single well-timed replenishment or cross-sell flow can lift repeat rate by 3-6 percentage points within a quarter - an incremental R280k to R560k, illustrative ZAR figures, without any new ad spend. Lifecycle flows built before acquisition scale give you compound revenue while CAC rises. Building them after acquisitions means you paid full price for every retained customer. Myth 3: More Channels Equal More Growth Adding TikTok Shop on top of Meta and Google before either engine is profitable usually just fragments creative and measurement. Post-signal loss - driven by Apple’s ATT changes and cookie deprecation - has made creative volume and clean server-side signal the dominant variables in paid social, not channel count. Two well-instrumented acquisition engines beat five poorly measured ones. Choosing Your Two Acquisition Engines and One Retention Engine Pick two acquisition engines that fit your margin profile and creative capacity. Add one retention engine. Expanding beyond that should require a documented reason: growing creative throughput, a new product line, or a market segment your existing engines genuinely cannot serve. Meta (Advantage+) - broad-reach discovery; plays well with impulse and visual categories. Google Shopping / Performance Max - captures high-intent search and Shopping demand. TikTok Shop - strong for trend-driven consumables and sub-$80 price points. Email/SMS (Klaviyo or similar) - the retention engine; drives the majority of repeat purchase revenue. Myth 4: Platform-Reported ROAS Tells You What to Do Platform dashboards report what they can see, not what actually happened. Post-ATT, Meta and GA4 routinely disagree with each other and with your Shopify order data by double-digit percentages. The gap is a measurement issue, not a marketing issue - and it belongs to whoever owns the data pipeline. How Server-Side Tracking and GA4 Change the Picture Server-side tagging - via GTM server containers, Meta’s Conversions API, and Google Enhanced Conversions - restores much of the signal lost to browser restrictions. GA4 plus a warehouse (BigQuery, Snowflake) gives you a single source of truth to reconcile against Shopify orders. In the US, CCPA/CPRA plus Virginia, Colorado, Connecticut, Utah, and Texas privacy laws make a documented consent model necessary; Consent Mode v2 and modeled conversions belong in any credible measurement plan.

Logistics and Fulfillment Services: The Growth Lever Most US Brands Misread

Why 'Logistics and Fulfillment Services' Is a Growth Question, Not an Ops Question Most US brands discover their fulfillment setup is broken at the worst possible moment: a peak-season email from a 3PL announcing a 22% surcharge increase, a wave of "where is my order" tickets, or a checkout conversion rate that quietly drops when shipping estimates shift from "2 days" to "5-7 days." By then the damage to acquisition efficiency is already booked. Fulfillment is not a warehouse problem. It is a unit-economics and retention problem that sits directly between your ad spend and your repeat purchase rate. When the delivery promise at checkout is inaccurate or slow, paid traffic converts worse, CAC rises, and the LTV assumptions baked into your media budget stop holding. That is why Prebo Digital treats fulfillment decisions as part of the growth stack - alongside performance media, CRO, and tracking - rather than a vendor procurement exercise delegated entirely to ops. This article dismantles five myths that repeatedly cost US brands six figures in avoidable margin, then gives you a formula, a decision table, and a tracking checklist you can apply this quarter. Myth 1: Fulfillment Is Purely an Operations Cost Line Fulfillment shows up in your P&L as COGS and shipping expense, which is exactly why it gets managed as a cost to minimise. But the same line item drives revenue-side metrics most teams track separately. A brand shipping in 2-3 business days versus 5-7 days rarely sees a neutral swap. Shoppers compare delivery windows at checkout, and slower promises correlate with higher abandonment. Baymard Institute's long-running cart abandonment research consistently places shipping cost, speed, and lack of transparency among the top reasons US shoppers abandon - not a niche pattern, but one of the dominant ones. If your slow or opaque shipping promise costs you even three percentage points of checkout conversion on $2M in annual revenue, that is roughly $60,000 of top-line revenue before you account for the compounding effect on repeat buyers. Fulfillment decisions change your CAC, your conversion rate, and your repeat rate. Treat the warehouse contract with the same rigour you apply to your ad account. Myth 2: The Cheapest Per-Pick Fee Wins A $1.85 pick-and-pack quote looks better than a $2.40 quote until you compare the invoices three months later. Per-pick pricing is the headline; it is almost never the bill. US carriers price on billable weight, which is the greater of actual weight or dimensional weight. Dimensional weight uses a divisor - commonly 139 for daily rates on major US carriers - applied to length × width × height in inches. A lightweight but bulky item can be billed at three to five times its physical weight. Copy the exact divisor from the carrier's current published rate page, because these change. DIM weight (lb) = (Length x Width x Height in inches) / 139 Billable weight = MAX(actual weight, DIM weight) Example: 18 x 14 x 10 in box holding a 1.2 lb item DIM weight = (18 x 14 x 10) / 139 = 18.1 lb Billed at 18 lb, not 1.2 lb A 3PL that packs loosely to hit speed targets will destroy your savings on a tighter pick fee. Packaging discipline is a line item whether the vendor labels it or not. Myth 3: Outsourcing Automatically Fixes Fulfillment Problems Outsourcing does not fix a broken process; it transplants it. If your SKU data is messy, your inventory counts are stale, or your order routing rules are undocumented, a 3PL will inherit all three problems and charge you to discover them. The failure mode is predictable: onboarding goes well, then month three brings mismatched inventory counts, oversells, and a support queue that neither party owns. Before signing, audit three things: SKU naming consistency, inventory sync frequency, and the exact inbound receiving process for your carton dimensions. Myth 4: You're Too Small to Outsource Fulfillment The traditional break-even advice - "wait until you hit 500 orders a month" - is stale for US DTC brands. Below roughly 150 orders a month, in-house is usually cheaper; between 150 and 500 orders, the decision turns on packaging complexity and whether you sell anywhere near a carrier zone you can't reach efficiently. The real trigger is not volume alone; it is whether the founder's hours spent packing would generate more revenue spent on acquisition, CRO, or inventory planning. That is a margin question, not a size question. Myth 5: Fulfillment Has Nothing to Do With Marketing This myth is expensive because it splits accountability. Marketing promises a delivery window; ops decides whether that promise is real. When they diverge, paid traffic pays the price. Three surfaces sit directly between fulfillment and marketing performance: the delivery promise shown on the product and cart page, the shipping threshold used to drive AOV, and the refund and cancellation events that must be tracked for accurate reporting. If refund events do not reach your analytics, every channel's reported ROAS is inflated by revenue you never kept. If GA4 records purchases but not refunds, your channel-level ROAS is overstated. Fix event parity before scaling spend. Fact Check: What US Shipping Data Actually Shows Three data points should anchor any US fulfillment decision: Cart abandonment: Baymard's research places extra costs - chiefly shipping - among the top reasons US shoppers abandon checkout, with shipping cost and slow delivery both recurring drivers. Returns: the NRF and Appriss Retail consumer returns reporting has put total US retail returns in the hundreds of billions annually, with online return rates running materially higher than in-store. Returns handling is a first-class cost, not an afterthought. Surcharges: UPS and FedEx publish annual peak and demand surcharges with dated effective periods. These are not negotiable at small volume. Budget them in advance. The Hidden Cost Drivers: DIM Weight, Peak Surcharges, and Returns Three costs are routinely omitted from vendor comparisons: DIM-driven packaging overhang: the gap between actual and billable weight across your full SKU catalogue. Peak surcharges: the multi-week windows when per-package fees rise, applied to both origin and residential deliveries. Returns processing: inspection, restock, and liquidation costs, which often cost more per unit than outbound picking. A realistic US DTC example: a brand shipping 2,000 orders a month might pay ZAR 55-95 per order in all-in fulfillment (roughly USD 3-5), but the spread between a well-designed integration and a poorly designed one can exceed ZAR 190 per order (about USD 10) during peak weeks. How US Sales Tax Nexus Changes Where You Store Inventory Post- Wayfair , most US states can require an out-of-state seller to collect sales tax once economic thresholds are crossed. Physical inventory placement in a state is a separate trigger. This is informational, not legal advice - confirm your position with a qualified tax professional before committing to multi-node storage.

Digital Marketing for eCommerce: Myths, Facts, and the Action Plan That Actually Drives Revenue

Why Most eCommerce Marketing Advice Is Quietly Costing You Money Search for "digital marketing for eCommerce" and you get a wall of confident prescriptions: raise your budget, chase a 4x ROAS, post more organic content. The problem is that most of this advice was written for a different business stage, a different margin structure, or a different decade of tracking. Applied blindly to a US Shopify or WooCommerce store, it quietly erodes contribution margin - you spend more, report more conversions, and bank less. The US Census Bureau puts eCommerce at roughly 15-16% of total US retail sales, meaning the overwhelming majority of buying still happens offline and hybrid journeys dominate. That single fact reframes everything: your marketing does not operate in a clean digital vacuum, and the platform dashboards that claim credit for every sale are telling a partial truth. Below are six myths we see repeated across US DTC and B2B eCommerce accounts, each paired with a verifiable fact and one concrete action you can take this week. Myth #1: 'ROAS Is the North Star' - Fact: Blended MER and Contribution Margin Decide Profitability Platform ROAS is calculated inside the platform's own attributed world. When Meta and Google both claim the same conversion, your blended reality is smaller than the sum of the dashboards. Blended MER - total revenue divided by total ad spend - is a harder, more honest number, and contribution margin tells you whether that revenue was worth acquiring. MER = Total Revenue (all channels) ÷ Total Ad Spend (all channels) Contribution Margin = Revenue - COGS - Shipping & Fulfilment - Payment Fees - Ad Spend - Variable Software Costs Action this week: Pull last month's total revenue from Shopify and total spend from all ad platforms. Calculate MER. Compare it to platform-reported ROAS. Most US brands find a 20-40% gap - that gap is the accuracy problem you are optimising against. If your blended MER is below your break-even threshold, a 5x ROAS in the Meta dashboard is not saving you - it is hiding a margin problem. Myth #2: 'Scale Ad Spend to Scale Revenue' - Fact: CVR and AOV Moves Must Come First Spending into a leaky funnel multiplies the leak. Baymard Institute's long-running research puts average documented cart abandonment around 70%, with roughly 48% of abandoners citing extra costs (shipping, tax, fees) and about 26% citing forced account creation. Those are conversion-rate problems, not media problems - and they cost you on every single session, paid or organic. ~70% Average documented cart abandonment rate; ~48% cite extra costs (Baymard Institute) Action this week: Run a five-minute mobile checkout audit on your own store. Add a product, get to checkout, and count the taps remaining. If guest checkout is not offered above the fold, or if shipping cost is not disclosed before the payment step, you have found budget you can redeploy into fixing the funnel instead of feeding it. Myth #3: 'iOS Killed Tracking, So Attribution Is Impossible' - Fact: Server-Side and Consent Mode Restore the Signal Browser-side loss is real, but 'impossible' is a choice. Server-side tagging, GA4's enhanced ecommerce events, and Google's Consent Mode give you a materially recovered picture. Note the distinction: Consent Mode is mandatory for advertisers targeting the EEA/UK, which matters to any US brand selling internationally - it is context, not a US legal requirement. A clean GA4 ecommerce implementation passes item-level data (item_id, item_name, price, quantity) through every funnel event - view_item, add_to_cart, begin_checkout, purchase. Without item data, no attribution model can tell you which products actually convert. The Measurement Stack That Makes Every Other Decision Possible Before channel strategy, before creative testing, you need a stack that survives cookie loss. For most US eCommerce brands that looks like: GA4 with full ecommerce events, Google Tag Manager for tag governance, server-side container for durable event delivery, and a reconciliation layer (a spreadsheet or warehouse table) where blended numbers are checked against platform numbers monthly. Layer Tool Job Collection GA4 + GTM Capture item-level funnel events Delivery Server-side container Survive browser restrictions Reconciliation Warehouse / sheet Compare blended vs platform truth Myth #4: 'SEO Is Too Slow for eCommerce' - Fact: Paid Buys Attention, Organic Buys Margin Paid media rents demand; organic and lifecycle marketing own it. Paid produces a spike that stops when spend stops; SEO compounds into a lower-CAC acquisition channel over 6-18 months. The mistake is treating them as substitutes. They are complements with different payback periods - and a US brand that never builds organic is permanently exposed to rising CPCs. Action this week: Identify your five highest-margin products. If none of them rank for a non-branded search query, you are paying full price for demand you could be earning. Myth #5: 'More Traffic Equals More Revenue' - Fact: Intent Match and PDP Quality Determine Payoff TikTok traffic and high-intent Google Search traffic are not interchangeable. A broad-reach campaign sending cold users to a product page with three sentences and no reviews converts far worse than the same spend sending mid-funnel users to a comparison page with social proof. Intent match at the ad-to-landing-page handoff is where most US DTC accounts lose their efficiency. Myth #6: 'Email and SMS Are Nice-to-Haves' - Fact: Owned Channels Are the Lowest-CAC Revenue You Control For mature DTC brands, lifecycle email and SMS commonly account for a meaningful double-digit share of total revenue - frequently in the 20-30% range in published Klaviyo benchmark reporting, though this varies widely by category and list health. Crucially, owned-channel revenue is not subject to auction inflation. It is the one channel where the audience is yours. Action this week: Check your welcome, abandoned-cart, and post-purchase flows. If any of the three is missing or generic, that is the fastest CAC reduction available to your store.

Online Retail Strategies That Actually Grow Profit in the US Market

Myths About Online Retail Strategy That Quietly Drain US Brand Profit Most US eCommerce operators do not lose money because they are lazy. They lose money because they inherit a set of assumptions that sound like strategy but behave like leaks. Four myths in particular recur across the Shopify, WooCommerce, and B2B retail accounts we audit at Prebo Digital, and each one has a measurable cost attached to it. Myth 1: More Traffic Always Means More Revenue Traffic is an input, not an outcome. If your checkout leaks, more traffic simply accelerates the leak. Baymard Institute's long-running aggregate puts average documented cart abandonment near 70% across US and global retailers, meaning roughly seven in ten initiated checkouts never convert. Adding 20,000 monthly sessions to a funnel with a 1.4% conversion rate produces less incremental revenue than lifting that rate to 1.9% on the same traffic - and the second option costs nothing in media spend. Myth 2: Discounting Is the Fastest Way to Grow Discounts do produce revenue spikes. They also reset customer price expectations, train repeat buyers to wait for the next promotion, and compress contribution margin on every subsequent order. A 15% sitewide discount applied to a product with a 55% gross margin removes roughly 27% of gross profit per unit. If those discounted customers return at full price less often - which is the typical pattern - the promotion has borrowed revenue from next quarter rather than created it. Myth 3: Platform-Reported ROAS Is the Truth Platform-reported ROAS is a directional signal produced by a system that is optimised to claim credit. In a US environment shaped by CCPA, cookie restrictions, and Consent Mode behaviour, Meta, Google, and TikTok each apply their own modelled conversions - and those models can both under-count (when consent is denied and events are dropped) and double-count (when the same purchase is claimed by two platforms). The number in the ad manager is not the number in your bank account. Myth 4: You Have to Be on Every Channel Channel sprawl is one of the most reliable ways to destroy attribution clarity. A brand running Google Ads, Meta, TikTok, Pinterest, and LinkedIn with a small team typically cannot produce enough creative volume, enough testing velocity, or enough clean data to make any single channel work well. Two channels executed with disciplined measurement will usually beat five channels running on autopilot. If your growth plan starts with "spend more", your plan is missing a diagnosis step. The leak almost always sits between landing and checkout, not at the top of the funnel. What the Data Actually Says About Online Retail Performance in the US The US Census Bureau's Quarterly Retail E-Commerce Sales series is the most stable public anchor for how online retail behaves relative to total retail. For years, eCommerce has held roughly 15-16% of total US retail sales, growing steadily but not explosively. The practical implication is that the market is no longer in a land-grab phase. Growth now comes from share within categories and from repeat purchase behaviour, not from the rising tide of a channel shift. ~70% Average documented cart abandonment across large-scale Baymard studies - the single largest recoverable loss in most US retail funnels. How Consent and Privacy Changes Reshape US Retail Measurement CCPA gave California consumers the right to opt out of the sale or sharing of personal information, and Consent Mode in Google's ecosystem lets tags adjust behaviour depending on the user's choice. When a US visitor declines tracking, your standard client-side GA4 purchase event may not fire, the platform pixel may receive a modelled conversion instead, and remarketing audiences shrink. Nothing is "broken" - but the picture in every dashboard is now a composite of observed and modelled data, and it needs to be treated that way. Learn how this applies to your store: reconciling platform-reported conversions against your Shopify or WooCommerce order data is the fastest way to see how much of your reported ROAS is modelled. Why Bottom-of-Funnel Fixes Outperform Top-of-Funnel Spend Core Web Vitals - Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift - are the closest thing the industry has to a standardised, measurable proxy for checkout friction. A product page with a slow LCP, a janky variant selector, or a checkout form with unnecessary fields is not a design opinion; it is a quantified drop-off point. Baymard's checkout usability research has repeatedly found that form-field friction and forced account creation are among the top reasons US shoppers abandon. The Strategies That Move Profit, Ranked by Leverage Not all improvements are equal. Ranked from highest to lowest leverage for a typical US retailer doing between $1M and $30M in annual online revenue: Rank Leverage layer Typical time to impact 1 Measurement foundation 2-4 weeks 2 Funnel sequencing and channel focus 4-8 weeks 3 Disciplined CRO testing cadence 6-12 weeks 4 Retention economics 8-16 weeks Leverage Layer 1: A Measurement Foundation Before Any Spend GA4 plus Google Tag Manager plus server-side tagging plus Consent Mode is the working stack. Before scaling media, you need a single source of truth for purchase events that can be reconciled against your commerce platform's order table. Without that reconciliation, every ROAS number downstream is an estimate with an unknown error margin. Leverage Layer 2: Funnel Sequencing and Channel Focus Sequence channels rather than running them in parallel from day one. Own the bottom of the funnel (brand search, retargeting, email and SMS recovery) first, then layer mid-funnel demand capture, then top-of-funnel awareness. Prebo Digital's growth engagements typically start with this sequencing because it protects contribution margin while you test creative volume. Leverage Layer 3: A Disciplined CRO Testing Cadence One test at a time, one hypothesis with a documented expected effect, minimum two business cycles of runtime, and a decision rule written before launch. Teams that test "whenever they have an idea" rarely accumulate a compounding advantage; teams that run a fixed cadence do.

Prebo integrates CRO work with GA4, Google Tag Manager, server-side tracking, and common ecommerce platforms like Shopify and WordPress to ensure accurate event capture and attribution. We also set up ETL or data-layer solutions where needed so test results feed into a single source of truth for decision making.

Common experiments include A/B tests, multivariate tests, funnel experiments, UX and checkout performance optimizations, and technical fixes that reduce friction. Test duration depends on traffic volume and required statistical power but typically ranges from several weeks to a few months per experiment cycle.

We prioritise revenue-per-visitor, conversion rate, average order value, customer acquisition cost (CAC), lifetime value (LTV), and marketing efficiency ratio (MER), alongside statistical significance for experiments. Clean attribution and centralized data pipelines ensure those metrics reflect true business impact rather than platform-reported figures.

CRO is designed to improve conversion efficiency and attribution accuracy, which can increase revenue and profitability when combined with product-market fit and adequate traffic. Outcomes vary by business and depend on test quality, funnel issues identified, and downstream economics, so results are not assured and are measured against revenue-focused KPIs rather than vanity metrics.

CRO is the systematic process of improving a website or funnel to increase revenue per visitor. Prebo Digital uses a technical-first, analytics-driven approach with hypothesis-driven experiments, server-side tracking, and funnel-level optimization focused on measurable revenue outcomes.
