Find answers to common questions
Budget requirements vary by industry, funnel and competitive intensity, but many advertisers need several thousand dollars per month to collect statistically useful conversion data; smaller budgets can still work if campaigns are tightly targeted to high-intent keywords or remarketing audiences. Prebo Digital designs spend strategies to prioritise profitable channels and scale when unit economics support it.
For eCommerce campaigns the focus is typically on Shopping, dynamic remarketing and ROAS-driven bidding tied to LTV, while B2B emphasises lead quality, account-based targeting, longer attribution windows and CPL/CPA optimisation. In both cases measurement, funnel optimisation and cross-channel attribution are prioritised to ensure spend drives revenue, not just clicks.
Prebo Digital implements clean data pipelines using GA4, Google Tag Manager, and server-side tracking, and ties platform data to on-site conversions and offline events where applicable to reduce attribution bias. Multi-touch attribution models and consolidated reporting are used to align spend with revenue and lifetime value rather than platform-reported last-click metrics.
Prebo Digital offers end-to-end Google Ads services including account audits, campaign strategy and setup (Search, Shopping, Display, Video, Remarketing), bid and budget management, conversion tracking implementation, and ongoing performance optimisations focused on revenue outcomes.
Time to profitability depends on product margins, funnel conversion rates, tracking accuracy and budget; an initial data-collection and learning phase commonly takes 4-8 weeks, with structured optimisation and scaling typically assessed over several months. Prebo Digital focuses on iterative testing and measurement to improve profitability rather than short-term traffic metrics.

Measurement essentials
90-day onboarding plan
Hiring an online advertising agency shapes your CAC, customer lifetime value (LTV), and ultimately profitability. This guide explains how to hire an online advertising agency with a focus on measurable revenue outcomes, accurate attribution, and scalable media strategies across Google, Meta, TikTok, and LinkedIn in the United States.
Start by converting business goals into measurable outcomes: new customers per month, target cost per acquisition (CPA), acceptable customer acquisition cost as a percentage of LTV, and MER targets. Document current baseline metrics from your analytics - monthly revenue, average order value (AOV), and channel-level CAC - so prospective agencies can propose realistic roadmaps.
| Week | Focus | Deliverable |
|---|---|---|
| 1 | Discovery & baseline | Data audit, measurement plan |
| 2-4 | Strategy & build | Media plan, tracking implementation |
| 5-12 | Test & optimise | Creative tests, bid & funnel optimisations |
| Ongoing | Scale & report | Quarterly growth roadmap |
For a practical example of a performance-first agency approach and core services that support this onboarding timeline, review our services overview.
Technical capability is non-negotiable. Any agency you hire should be able to map and implement a measurement plan that reduces platform attribution leakage and supports revenue-based reporting.
If you want a concise URL that describes our overall approach to measurable growth systems, see our homepage, which outlines how strategy, analytics, and engineering combine to protect revenue attribution.
Agencies price differently: percentage of ad spend, flat retainers, performance-linked fees, or hybrids. Focus on projected impact to CAC and LTV rather than headline fees. Ask for modelled scenarios showing expected revenue lift and CAC at different spend levels (e.g., $10k, $25k, $50k monthly). Clarify inclusions: does the retainer include CRO, creative production, analytics, or are those add-ons?
| Item | Service Model A | Service Model B |
|---|---|---|
| Monthly fee | $5,000 retainer | 10% of ad spend |
| Tracking | Server-side + GA4 | Pixel-based only |
| CRO | Included (tests monthly) | Optional, extra |
Match the agency's campaign structure to your funnel: TOF (awareness), MOF (consideration), BOF (conversion). A balanced approach ensures you’re not over-indexing on upper-funnel tactics that don't move revenue.

If you want to understand how an agency like Prebo Digital structures long-term partner retainers and reporting, read our about page for our approach to revenue-driven partnerships and transparent attribution.
Create an internal governance plan: weekly ops, monthly strategy reviews, and quarterly growth planning. Track both short-term test results and cohort-level LTV changes over 6-12 months. Prioritise building clean data pipelines so decisions are made on consolidated revenue data rather than platform-reported conversions alone.
For founders and growth leaders running Shopify or WooCommerce stores, ensure the agency can connect order data to ad platforms and to your email automation system (e.g., Klaviyo) for accurate audience building and LTV reporting. Learn more about this systems approach on our services overview, which covers tracking, CRO, and media as a unified stack.
