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.

Pricing models
Budget framework
Track before you scale
When founders and growth teams ask "what is the cost of online advertising services," they’re asking two questions: the agency or management fee, and the ad spend required to drive results. Costs vary by channel (Google Ads, Meta, TikTok, LinkedIn), campaign complexity, and desired outcomes. Below we break down pricing models, typical US ranges, and how to budget for revenue-first outcomes.
Below are typical ranges used in the US market. These are experience-based estimates and should be treated as ranges, not guarantees. All dollar figures are shown in USD ($).
| Service | Typical agency fee | Ad spend range (monthly) |
|---|---|---|
| Paid search (Google Ads) | $1,500-$8,000+/month or 10-20% of spend | $1,000-$200,000+ |
| Social (Meta/TikTok/LinkedIn) | $1,200-$6,000+/month or 10-20% of spend | $500-$150,000+ |
| Strategy & tracking (GA4, server-side) | $2,000-$12,000 (setup) + monthly maintenance | N/A (one-time + ongoing) |
Example scenarios: a small Shopify store may pay $1,500/month to an agency and run $3,000/month in ads; a scaling eCommerce brand often budgets $8,000-$25,000/month in management fees and $50,000+ in ad spend to sustain multi-channel growth. These are examples for planning; actual bids should reflect target CAC, LTV, and MER.
Note: Pricing should be aligned to revenue impact. Ask prospective partners how fees map to CAC reduction, LTV improvements, and attribution clarity rather than vanity metrics.

Budget decisions should start with targets: desired monthly revenue, target CAC, and acceptable MER (Marketing Efficiency Ratio). Below is a simple funnel and budgeting framework to translate revenue goals into ad spend and service investment.
| Stage | Tactics | Budget share |
|---|---|---|
| Top of funnel (TOF) | Prospecting ads, broad audiences, video | 40-60% |
| Middle of funnel (MOF) | Retargeting, email nurturing, lookalikes | 20-35% |
| Bottom of funnel (BOF) | Dynamic product ads, search, direct response | 15-30% |
Assume target monthly revenue $50,000 with a target CAC of $50 and an average order value (AOV) of $100. You would need ~1,000 orders. At a $50 CAC, required ad-driven orders are 1,000 and total ad spend would be about $50,000. Agency fees to run and optimize those channels could reasonably fall between $5,000-$12,000/month depending on scope. These figures are illustrative and depend on conversion rates, channel mix, and LTV assumptions.
Accurate attribution affects both budget allocation and perceived agency performance. A clean tracking stack reduces wasted spend and improves bid logic across platforms. A simple conversion tracking diagram often used in US eCommerce setups:
| Layer | Role |
|---|---|
| Browser (client) | Capture clicks, first-party cookies, initial events |
| Server-side (S2S) | Event de-duplication, enhanced attribution, reduced ad blocker loss |
| Analytics (GA4 / dashboards) | Unified reporting, MER calculations, ETL for business intelligence |
Investments in server-side tracking or ETL may add $2,000-$12,000 in initial setup costs but often pay back through cleaner attribution and lower wasted ad spend. For technical tracking implementations and how they integrate with growth systems, see our homepage and service notes.
If you want an agency proposal that maps expected lift to cost, request a scoped growth audit and a modeled projection. For booking and next-step logistics, Prebo Digital accepts inquiries via our contact page, where you can request a tailored growth audit.
