Questions and deliverables to compare proposals and protect attribution accuracy.
The cost of hiring a PPC and CRO agency depends on the scope (ads vs. conversion work), billing model, and the technical complexity of your stack. For US-based founders and marketing leaders, price should be framed against expected revenue impact, CAC reduction, and attribution accuracy - not just hourly rates or retainers. This guide explains common pricing models, sample ranges in USD, and the trade-offs to watch for when evaluating proposals.
Below are generalized ranges for US eCommerce and B2B brands. These are estimates and will vary by agency experience, vertical, and scope.
| Service | Common pricing models | Estimated US range |
|---|---|---|
| PPC Management (Google/Meta/TikTok) | Monthly retainer, % of ad spend | $1,500-$10,000+/month or 10%-20% of ad spend (estimate) |
| CRO (audit, tests, implementation) | Project or monthly retainer | $2,000-$8,000+/month or $5,000-$30,000+ per project (estimate) |
| Full PPC + CRO retainer | Bundled retainer | $4,000-$20,000+/month depending on scope (estimate) |

| Stage | Primary events | Where to track |
|---|---|---|
| TOF (awareness) | Impressions, clicks | Ad platform + server-side click layer |
| MOF (consideration) | Adds to cart, signups, product views | GA4 + data layer + tag manager |
| BOF (conversion) | Purchases, demo requests, LTV events | Server-side events, CRM, and ETL to BI |
Note: For US advertisers, proper server-side tracking and consent-aware implementation is essential to protect attribution accuracy and comply with state privacy rules.
Several factors drive the final price: agency experience, required technical integrations (GA4, server-side tagging, CRM/ETL), testing velocity for CRO, creative production, and the complexity of your product catalog. Below are practical scenarios in US dollars to help you budget.
Monthly PPC retainer $1,500-$3,000 + ad spend. CRO project $2,000-$6,000 for initial audit and 2-4 tests. Expect a 3-6 month ramp to measure meaningful impact depending on traffic. These are estimates and depend on average order value (AOV) and conversion rate.
Combined retainer of $6,000-$12,000/month for integrated PPC and CRO, plus $10k-$50k/month in ad spend. Agencies in this band typically include GA4 migration, server-side event routing, and a roadmap of tests aligned to unit economics. Model payback by projecting incremental monthly revenue and comparing to the retainer; the agency should provide scenario modeling as part of the proposal.
More complex funnels, higher LTVs, and longer sales cycles mean agencies often charge $8,000-$20,000+/month for full-funnel PPC and CRO retainers. Work typically includes deep analytics (server-side tracking, CRM stitching), multi-touch attribution, and landing page experimentation focused on qualified leads rather than raw conversions.
State privacy rules (for example, CCPA in California) and browser restrictions affect event visibility. Agencies must build consent-aware server-side pipelines and document gaps between platform-reported conversions and cleanly attributed revenue in your data warehouse. If you need a technical-first partner that focuses on accurate attribution and scalable tracking, learn more about our approach on the About Prebo Digital page.
Ask agencies to provide:
If you want a hands-on review of a proposal or a growth framework that maps costs to revenue outcomes, consider requesting a targeted audit or strategy session via the contact page: Contact Prebo Digital. That conversation should focus on payback period, testing roadmap, and data hygiene rather than raw hourly rates.
Budget with outcomes in mind. For US stores, a sensible starting combined budget for performance-focused PPC + CRO work is often in the $4,000-$12,000/month band for businesses seeking predictable growth and cleaner attribution. Smaller budgets can still move the needle but expect longer timelines and fewer simultaneous experiments. Ask agencies to show revenue scenarios in $ to align investment with expected returns.
