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.

Evaluation Checklist
Paid media optimization agency pricing comparison is about more than hourly rates - it reveals different approaches to strategy, attribution, and outcome measurement. Agencies price by value delivered (revenue uplift, CAC reduction), the complexity of tracking and attribution, and the scale of media spend. For US-based founders and marketing leaders, understanding these models helps align budgets with measurable business goals, not vanity metrics.
Each model shifts risk and incentive. A retainer rewards long-term optimization and technical builds like server-side tracking; percent-of-spend ties the agency to scaling activity; revenue-share can align incentives but requires clean attribution and contractual clarity.
| Model | Typical Range (US) | Best for |
|---|---|---|
| Monthly retainer | $3,000-$12,000+/month | Complex builds and CRO-supported growth |
| % of ad spend | 10-20% of media spend | Scaling established campaigns |
| Revenue-share / performance | Varies; often tiered based on incremental revenue | High-confidence, measurable funnels |
Example: a Shopify store spending $50,000/month might pay $5,000-$10,000/month on a percent-of-spend model (10-20%). A growth-focused retainer for similar complexity could be $6,000/month if it includes analytics, GA4 + server-side tracking, and CRO testing. These figures are US-focused estimates and should be treated as ranges rather than guarantees.

When comparing proposals, prioritize measurable revenue impact and attribution clarity. Ask vendors to map costs to outcomes: how much is allocated to tracking and analytics vs. creative and bidding? A well-priced engagement balances strategy, build, test, and scale phases so your CAC reduces while LTV improves.
