What a Google Ads Audit Actually Reveals About a London SME Campaign

A Google Ads audit of a typical London SME account reveals the same issues in the same order with remarkable consistency: broken or duplicated conversion tracking, broad match keywords without negative keyword lists consuming 30 to 45 percent of the budget on irrelevant searches, and campaigns that have never exited the learning phase because budget was too fragmented to accumulate sufficient conversion data. These are not edge cases. They are the baseline.

Most London SME Google Ads accounts were either set up by someone without specialist training or by a junior account manager at a large agency with too many accounts to manage carefully. Google's platform is designed to encourage spend. Default settings, recommended settings, and automated suggestions from the platform consistently push accounts toward configurations that generate more clicks and spend, not more profitable conversions. A Google Ads agency in London that audits accounts regularly sees the same structural problems in most campaigns they inherit.

The result is predictable. Broad match keywords match searches that have nothing to do with the business. Search and Display campaigns are combined, corrupting the data from both. Conversion tracking fires on page views instead of form completions, making the algorithm optimise for people who looked at the thank-you page URL rather than people who actually submitted a form. Smart Bidding, which depends on conversion data to function, optimises for nothing.

Wasted spend in a Google Ads account is not abstract. It is money paid for clicks from searches that could never produce a conversion, or clicks that produced a conversion signal but not an actual lead or sale. In a London professional services account spending £3,000 per month, wasted spend of 35 percent means £1,050 per month is going to searches that will never produce business. At 45 percent, it is £1,350 per month.

The Search Terms report shows this with precision. Every week, this report reveals what actual user searches triggered your ads. A solicitor running ads for 'employment law advice' routinely sees their budget consumed by searches like 'employment law courses', 'employment law books', and 'employment law Wikipedia'. Each of those is a search from someone with no intent to hire a solicitor. Each one was paid for. A comprehensive negative keyword list added in week one typically reduces wasted spend by 20 to 35 percent before any other change is made.

The priority order in every audit is: fix tracking first, then fix negatives, then fix structure, then fix bidding strategy. Changing bids before tracking is fixed means changing bids based on wrong data. Adding more budget before structural problems are resolved means spending more on the same inefficiencies. Tracking is always first. This applies equally to standalone paid advertising campaigns and to accounts running alongside an SEO programme.

A thorough audit of a standard SME account, one to five campaigns across Search and Display or Shopping, takes three to five business days to complete properly. It covers tracking verification, campaign structure, keyword analysis, ad copy review, Quality Score assessment, and wasted spend quantification. We deliver the audit as a prioritised action plan, not just a list of issues.

Preserve the account in almost all cases. Account history, Quality Scores, and conversion data accumulated over time have value. Even a poorly structured account has historical data that informs better decisions if you know how to read it. Starting fresh loses that data and extends the learning phase for new campaigns. The exception is an account with a history of invalid clicks, manual penalties, or systematically corrupted conversion data where the history itself is the problem.

Wasted spend reduction alone typically produces a 20 to 40 percent improvement in cost per qualified lead without any additional budget. Structural improvements that fix campaign architecture and Quality Scores produce further gains over two to three months. The full improvement from a professional rebuild of a poorly structured account, measured over six months, regularly exceeds 50 percent reduction in cost per lead for accounts that were in poor shape. The absolute numbers depend on your sector, keyword competition, and landing page quality.
