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.

Prepare a concise brief
Request funnel-aligned scope
Prioritise attribution clarity
Requesting a quote from a PPC retainer agency is more than asking for price ranges - it is the first step toward a measurable revenue partnership. Agencies price retainers based on scope, expected outcomes, tracking complexity, and the cleanup required to produce reliable attribution. If you’re a US-based founder, marketing director, or Shopify store owner, preparing a concise, data-driven brief reduces back-and-forth and produces more accurate proposals.
Including this data upfront helps agencies scope work across strategy, tracking remediation, creative testing, and optimization cadence. For a template-driven start, agencies often ask for a short data export (CSV) showing monthly revenue vs media spend - sharing those numbers accelerates a realistic quote.
If you want to align the ask with a partner that uses a technical-first approach, see Prebo Digital’s services overview to confirm capabilities like server-side tracking and attribution-first reporting Services overview. For quick context on agency approach and team structure, refer to the agency homepage Prebo Digital homepage.
Retainer models vary but commonly include some combination of fixed scope plus media management fees. Typical models are:
When requesting a quote, ask agencies to clarify what’s included (creative testing, landing pages, CRO, GA4 and server-side tagging) and what’s excluded (ad creative production costs, third-party tool subscriptions). Clear inclusions reduce scope creep and help you compare proposals apples-to-apples.
Quick tip: If your store uses Shopify or WooCommerce, note plugin-based tracking (e.g., server-side Shopify setups) and share access windows early. That reduces the agency's discovery time and shortens the proposal cycle.
As you compile answers, track agency responses against the same brief. Agencies that emphasize attribution clarity, conversion tracking diagrams, and funnel optimization are easier to integrate into long-term growth plans.
| Source | Tracking Layer | Primary Metric |
|---|---|---|
| Google Ads | Gtag -> GTM -> Server-side endpoint | Attributed revenue (7-day view) |
| Meta | Conversion API (server-side) | Purchases & value |
Use the checklist below when drafting your RFP or inquiry email. Include attachments or access notes where possible to allow agencies to run a quick diagnostic.
Pricing varies by complexity. These are example ranges for US-based eCommerce and service brands (estimates):
| Scenario | Typical monthly retainer (est.) |
|---|---|
| Small eCommerce, <$15k media/mo | $2,000-$4,000 |
| Mid-market, $15k-$100k media/mo | $4,000-$12,000 |
| Complex B2B or enterprise | $12,000+ |
These ranges are illustrative; ask the agency for a breakdown showing hours allocated to strategy, tracking, creative testing, and reporting so you can compare cost-per-deliverable rather than headline price.
A structured proposal should map work to the funnel. Use TOF → MOF → BOF language when requesting the quote so scope aligns with measurable outcomes:
When agencies lay out tests per funnel stage and link each to a KPI (e.g., CAC, conversion rate, incremental revenue), you can evaluate their strategic thinking, not just their bidding tactics.
In the United States, privacy controls and state laws like the CCPA affect signal availability and consent flows. Ask agencies how they handle cookie consent, hashed customer data, and server-side fallbacks to protect measurement accuracy while staying compliant.
Also request a sample onboarding timeline and expected milestones - for example: week 1 access, weeks 2-3 tracking remediation, week 4 launch optimizations. If you want a partner experienced in technical tracking and attribution, the Prebo Digital about page explains our approach and experience About Prebo Digital, and the contact page is useful when you’re ready to schedule a detailed briefing Contact Prebo Digital.
When proposals arrive, compare them on these axes: expected revenue impact, scope clarity, tracking fixes included, test roadmap, and reporting fidelity. Prioritize partners that propose measurable tests and clean attribution over those that focus only on traffic or click metrics.
