Google Ads Audit: How to Tell Whether Your Campaigns Are Leaving Potential on the Table

Most Google Ads accounts we analyse for prospects leave between 20 and 50 percent of their potential untapped. We explain what a serious audit really covers, which weak spots come up most often and how to tell whether an audit is substantial or superficial.

Most Google Ads accounts we analyse for prospects leave between 20 and 50 percent of their potential untapped. Not because the previous management was bad, but because many issues only become visible with distance and a fresh pair of eyes.

What a good Google Ads audit covers

A professional audit goes far beyond a quick look through the account. It examines the entire advertising system: tracking, account structure, feeds, campaigns, bidding strategies, ads, audiences and the strategic direction.

Tracking audit

Every serious audit starts with tracking. If the data is wrong, all downstream analysis is worthless. In our experience, we find tracking issues in roughly three quarters of all accounts - issues that aren't obvious but measurably distort decisions.

Structural audit

The campaign structure is checked for its strategic logic. Is the separation between brand and non-brand clean? Are Shopping campaigns sensibly segmented? Is Performance Max set up so that it doesn't compete with other campaigns?

Feed audit

For e-commerce accounts, the feed audit is central. We check the quality of product titles, the use of structured data, and the correct assignment of google_product_category and product_type.

Search term and keyword analysis

A systematic analysis of search term reports shows which queries actually triggered your ads. Significant volumes of irrelevant search queries often surface here.

Ad and asset audit

The current ads are checked for freshness, quality and diversity.

Strategic big picture

Finally comes the strategic assessment: does the overall strategy fit the shop's current stage and the company's goals?

Typical weak spots that show up in almost every account

The first typical weak spot: Performance Max without a brand exclusion. The campaign eats your brand search traffic.

The second typical weak spot: messy Shopping feed titles. A systematic title overhaul often delivers double-digit percentage gains in Shopping revenue.

The third typical weak spot: neglected negative keyword lists.

The fourth typical weak spot: poor or missing enhanced conversion tracking.

The fifth typical weak spot: strategically over-budgeted retargeting.

How to recognise a good audit

A good audit is not a long list of generic pointers, but a differentiated analysis with concrete recommendations for action. The audit is specific to your account, not generic. The audit prioritises. The audit is honest about its limits. The audit has consequences.

When an audit makes sense

When your ROAS has been stagnating for months. When you work with an agency and aren't sure whether the management is worth the money. When you're considering a switch. When you want to increase your budget.

Conclusion: the audit as a strategic tool

A Google Ads audit is not just a hunt for errors - it is a strategic tool. It shows you what potential is dormant in your campaigns.
