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.

Comparing PPC management agencies requires more than price and ad creative samples. Founders, marketing directors, and growth managers in the United States need to prioritise revenue impact, accurate attribution, and long-term profitability. This guide shows how to compare PPC management agencies using measurable criteria, US-focused examples, and practical checklists.
Ask each agency the following during initial calls. Their answers reveal technical depth and commercial alignment.
Pro tip: request a short technical audit sample. A 30-60 minute tracking review shows whether an agency understands GA4, server-side events, and the US cookie/consent landscape (including CCPA implications).
Look for specific technical capabilities rather than generic statements. Examples include: ability to implement server-side conversions, use of enhanced conversions for web, event naming consistency across analytics and ad platforms, and a clear plan for funnel-level attribution (TOF → MOF → BOF).
If you want an example of how strategy ties to build and test phases, see our services overview here: Prebo Digital services.
| Layer | What to track | Why it matters |
|---|---|---|
| Client-side (browser) | Click IDs, pageviews, add-to-cart | Attribution signal + behavioural insights |
| Server-side | Purchase events, subscriptions, revenue | Resilient conversions and improved match rates |
| Analytics (GA4/BI) | Unified event taxonomy, custom dimensions | Cross-channel MER and LTV calculations |

Use the framework below to score agencies across quantitative and qualitative dimensions. Weight categories by importance to your business (for example, if CAC is critical, give tracking and optimisation more weight).
Assess how each agency plans activity across the funnel and how they measure success at each stage:
Scenario: a Shopify store with $250,000 annual revenue seeks lower CAC. Agency A prioritises platform-level ROAS without server-side tracking. Agency B proposes a phased plan: implement server-side events, align GTM and GA4, run structured A/B tests, and measure MER. Agency B's approach is designed to surface true revenue impact; Agency A may show higher platform ROAS but under-report cross-channel conversions. Estimated US examples: fixing attribution can reveal 10-30% more trackable revenue (estimates vary by store and setup).
When comparing proposals, request a work plan that maps Strategy → Build → Test → Scale → Report. If you want to read how we sequence these phases for clients, check our about page for process context: About Prebo Digital.
Request anonymised examples of dashboards or a sample tracking plan. Agencies that can share a spreadsheet or BI view that links ad spend to revenue are generally more reliable partners.
Common models include percentage of ad spend, flat monthly retainer, or performance-linked fees. Each has trade-offs-percentage fees can misalign incentives if revenue attribution is broken. Ask for precise inclusions: how many hours of optimisation, creative tests, reporting setup, and whether server-side tracking is included. For US eCommerce, budgeting $3,000-$10,000+ monthly for a high-performing retained PPC engagement is common, depending on complexity and ad spend (figures are estimates).

For next steps on vendor conversations, consider preparing a short RFP that asks for a tracking audit, a 90-day roadmap, and a sample measurement dashboard.
Score agencies using the framework, validate technical claims with a small audit, and prioritise partners who show clear alignment to CAC, LTV, and MER.
