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.

If your goal is profitable growth, knowing how to choose a PPC management agency means looking past surface-level metrics and platform badges. For US-based founders, marketing directors, and Shopify or WooCommerce store owners, the priority should be measurable revenue, clean attribution, and a repeatable growth system that reduces CAC while improving LTV. This guide outlines the evaluation criteria, measurement checks, and RFP questions that surface true capability.
PPC spend can scale quickly. Without accurate tracking and a strategy that connects ads to on-site conversion rate optimisation (CRO), accelerated spend often increases reported conversions but not profit. A strategic PPC partner coordinates media, landing pages, attribution, and data engineering-so every dollar is tied to an expected business outcome. Learn how this integrates with broader services on our services overview.
Quick tip: Ask for a recent audit sample showing how they reconciled Google Ads, GA4, and first-party order data for a US eCommerce client. The audit should show gaps and concrete remediation steps.
A modern PPC program optimizes across the top, middle, and bottom of funnel. Use this simple table to map ad intent to tactics and metrics.
| Funnel Stage | Tactics | Primary Metrics |
|---|---|---|
| Top of Funnel (TOF) | Prospecting on Google, Meta, TikTok; awareness creatives; layered audiences | Impressions, CTR, qualified traffic |
| Middle of Funnel (MOF) | Remarketing, lead-gen forms, product-specific ads, gated content | Engagement, leads, assisted conversions |
| Bottom of Funnel (BOF) | Dynamic retargeting, promo-focused search, CRO-optimized landing pages | Orders, revenue, ROAS (contextualized to profit) |

When you receive proposals, score them across strategy, measurement, and execution. Use weighted criteria: 30% measurement & attribution, 30% strategy & media plan, 20% CRO and landing page capability, 20% reporting and team fit. Request a pilot that lasts 60-90 days with a small media test budget and clearly defined KPIs.
Good agencies design for data quality. Expect GA4, client-side and server-side GTM, and a method to reconcile ad platforms with your order database. For US businesses, confirm how they handle consent and CCPA-related requests when designing tracking. Avoid partners that rely solely on platform pixels without a server-side fallback and first-party event stitching.
Common models include percentage of ad spend (often 10-20%), flat monthly retainers ($2,500-$10,000+ depending on scope), or hybrid models with performance incentives. For a $50,000 monthly ad budget, an agency fee of 10%-15% with a defined scope for tracking and CRO is a common starting point. These are illustrative ranges; ask for a line-itemed scope to compare apples to apples.
For eCommerce stores on Shopify, ensure the agency can build or iterate on Shopify landing pages and connect order webhooks into a server-side GTM container. If you're evaluating long-term partners, review team structure and ask to see the people who will execute day-to-day work. You can learn more about Prebo Digital's approach on our about page and how our services connect to retention and analytics on the contact page.
Choosing a PPC management agency requires a blend of media expertise and technical rigour. Prioritise partners who can demonstrate measurable revenue impact, transparent attribution, and a structured approach to testing and scale. See a real-world example by requesting an audit sample during the RFP process to validate their claims.
