In brief: Most Google Ads accounts at mid-sized companies burn 20–40 % of their budget in places a structured audit uncovers within a few hours. This article shows the seven most common budget killers – and how our Google Ads account audit makes them visible and fixable for you.
Why an account that “runs fine” still loses money
Google Ads is up and running at most companies. It delivers clicks, the occasional enquiry, the monthly invoice is debited – so everything seems to be in order. That is precisely the problem: an account that works somehow is rarely questioned. And because every Google update hands more of the work to automation (Performance Max, AI-driven bidding, “AI Max” for Search campaigns), more and more decisions disappear into a black box that nobody checks any more.
The uncomfortable truth: automation only optimises as well as its data foundation and its guardrails allow. Without clean conversions, clear exclusions and a well-considered structure, the AI will reliably optimise towards the wrong goal. The result looks good on the dashboard – but costs real revenue.
The 7 costliest mistakes
- 1. Conversions measure the wrong value. If every page view, every click on “call” and every newsletter sign-up counts as a “conversion”, Google optimises for activity instead of revenue. We check whether your conversions actually represent genuine business events – and whether they even arrive in full via Consent Mode v2.
- 2. Search terms nobody would ever have bought from. Without consistently reviewing the search terms report and maintaining negative keyword lists, you pay for enquiries from job applicants, competitors, tinkerers and “free of charge” searches. In almost every account we find double-digit percentages of wasted budget here.
- 3. Performance Max without guardrails. PMax is powerful, but greedy: without brand exclusions, audience signals and clean asset groups, the campaign devours cheap brand clicks and credits their conversions to itself. That looks like top performance – but it is often just reallocated revenue you would have had anyway.
- 4. A bidding strategy with no data foundation. “Maximise conversions” on an account with five conversions a month is like flooring the accelerator in fog. We check whether your strategy matches the volume of data available – and whether a target CPA/ROAS is realistically calibrated.
- 5. Ads that do not match the landing page. The most expensive click is the one that lands on a page which fails to deliver on the promise of the ad. Message match between keyword, ad and landing page is one of the biggest levers for Quality Score – and therefore for your cost per click.
- 6. Geography and ad scheduling on autopilot. Spend scattered across regions you do not even deliver to, ads running at three in the morning with nobody available to answer, location settings set to “interest in” rather than “presence”: small tick boxes, big impact.
- 7. No view of the competition. Auction insights and ad libraries reveal where you are over- or underbidding. Without that context you are optimising blind against opponents you cannot see.
What a structured audit changes
Taken individually, each of these points is unspectacular. Together they decide whether 1,000 € of ad budget turns into 1,300 € or 700 € worth of impact. The difference is not a question of “more budget” but of precision – and precision comes from a systematic, external look at the account.
That is exactly what we built the Google Ads account audit for: we take your account apart along a fixed review framework – account structure, conversions & tracking, search terms, bidding, ads, landing pages, competition – with particular focus on the new AI campaign types and the quality of your landing pages. You receive a 15–20-page audit with a concrete, prioritised action plan. Not a tool export, but plain language: what is costing you money right now, what will deliver the fastest gains, and in which order.
No risk: the results guarantee
We are convinced by the impact – and we carry part of the risk. Implement at least 50 % of our recommendations within six weeks and still see no measurable gain in effectiveness, and you get your money back. If you have questions about the implementation, we support you free of charge by email.
Instead of 399 €, the audit currently costs 199 € – until 30/09/2026.
