Google Ads agency

Google Ads agency: pricing, account scope and the numbers that decide it

Vibe Digital manages Google Ads for eCommerce brands and B2B/B2C lead generation teams. Transparent retainers, conversion tracking rebuilt from scratch, and targets set against your margin — not against a platform-reported ROAS screenshot.

TL;DR

  • Google Ads management starts at €419/month per platform for brand and traffic, €539/month for lead generation and €659/month for eCommerce, plus a variable percentage of ad spend over €900.
  • Setup is a one-time fee from €250 per social platform (€450 for Google Ads) covering conversion tracking, enhanced conversions, GA4 wiring and account restructure.
  • We set a break-even ROAS from your gross margin first, then a target ROAS with the margin of safety your cash flow needs.
  • Average client ROI across 700+ cooperations is +729%, with an average +94% improvement over the previous agency within four months.
  • Scope covers Search, Performance Max, Shopping, Demand Gen and YouTube — with PMax kept honest through asset-group and brand-exclusion controls.

What you actually pay at different budgets

Percentage-of-spend pricing is only fair if you can see it before you sign. Here is what a single-platform Google Ads retainer costs across common monthly budgets.

Monthly management fee examples (eCommerce, 10% of spend over €1,000, 6% above €25,000)
Monthly ad spendBase feeVariableTotal
€2,000€659€100€759
€5,000€659€400€1,059
€15,000€659€1,400€2,059
€30,000€659€2,700€3,359

Illustrative. Lead generation uses 8% and brand/traffic 5% on the same structure.

Set the target from margin, not from a benchmark

Break-even ROAS is 1 ÷ gross margin. At 45% margin that is 2.22 — below it, every extra euro of spend loses money before you have paid for fulfilment, returns or the retainer. Target ROAS sits above break-even by whatever contribution you need to fund the business.

For lead generation the same maths runs on pipeline: gross profit per closed deal × close rate gives the allowable cost per lead, and revenue per lead × leads ÷ spend gives a comparable ROAS.

What a Google Ads engagement includes

Every account gets the same foundation before spend is scaled. Most of the lift in the first 90 days comes from measurement and structure, not from bid tinkering.

  • Conversion tracking rebuilt: GA4, enhanced conversions, server-side events and consent mode v2
  • Account restructure across Search, Shopping, Performance Max, Demand Gen and YouTube
  • Merchant Center and feed hygiene: titles, GTINs, disapprovals, promotions
  • Brand vs non-brand separation so PMax is not billing you for demand you already own
  • Offline conversion imports from HubSpot, Pipedrive or Salesforce for lead gen accounts
  • Search term and placement pruning on a fixed weekly cadence
  • Creative and landing-page testing tied to a single primary conversion

The first 90 days

Our method, the Signal Loop, runs in three phases: send the signal (weeks 1–4) rebuilding tracking and structure; warm the audience (weeks 5–8) scaling offer and creative tests against clean data; close the loop (weeks 9–16) reallocating budget by profit contribution rather than platform-reported conversions.

How to choose a Google Ads agency

Shortlist three agencies and ask all of them the same questions. The answers separate operators from account babysitters.

  • What break-even ROAS or allowable CPA did you calculate from our margin?
  • How will you verify conversions server-side and handle consent mode?
  • How is Performance Max prevented from cannibalising brand search?
  • Which named senior person touches the account each week?
  • What is the total fee at our spend level, including setup, in writing?

FAQ

How much does a Google Ads agency cost?

At Vibe Digital, Google Ads management starts at €419 per month for brand and traffic, €539 for lead generation and €659 for eCommerce, each per platform, plus a variable percentage of ad spend over €900 — €1,000 for eCommerce (5%, 8% and 10% respectively, dropping to 6% on eCommerce ad spend above €25,000). Setup is a one-time fee from €250 per social platform (€450 for Google Ads) and there is no long-term contract.

Is a percentage of ad spend or a flat fee better?

A hybrid is usually fairest. A flat fee alone underprices large accounts and overprices small ones; pure percentage pricing rewards spending more rather than earning more. A base fee plus a capped percentage keeps the work funded while keeping incentives on efficiency.

What ROAS should we expect from Google Ads?

It depends entirely on gross margin. Break-even ROAS is 1 ÷ gross margin, so a 45% margin store needs 2.22 just to cover product cost. Our eCommerce clients average +913% return on ad spend across platforms, but the right target for you comes from your own margin and growth appetite.

Do you manage Performance Max and Shopping?

Yes. We run Search, Shopping, Performance Max, Demand Gen and YouTube inside one account strategy, with brand exclusions, asset-group segmentation and feed optimisation so PMax reporting stays interpretable instead of a black box.

How long until Google Ads works?

Tracking and structure are rebuilt in the first four weeks and efficiency usually moves inside the first month. Smart bidding needs roughly 30 conversions per campaign per month to stabilise, so a reliable read on profitability lands between weeks 9 and 16.

Do we keep ownership of the Google Ads account?

Always. We work inside your Google Ads, Merchant Center, GA4 and tag containers. You keep full admin access and all data if the engagement ends.
