Performance Max Tips for UK Advertisers in 2026

Small changes, meaningful impact

The biggest gains in performance max rarely come from a single major overhaul. They tend to come from a series of incremental improvements — each one small on its own, but compounding into significantly better performance over time. The tips in this guide are all practical, actionable and implementable without specialist knowledge.

Tighten your targeting

One of the fastest ways to improve performance max performance is to reduce waste by tightening who sees your ads. Review your geographic targeting — are you showing ads in areas you cannot actually serve? Check your audience exclusions — are you paying to show ads to existing customers or people who have already converted? Review device bid adjustments — does your conversion rate differ meaningfully between mobile and desktop?

Each of these takes less than ten minutes to review and adjusting just one can meaningfully reduce your cost per lead.

Improve your Quality Score

Quality Score directly affects how much you pay per click and how often your ads show. The three components are expected click-through rate, ad relevance, and landing page experience. Improving any of them reduces your cost and improves position.

The quickest wins are usually tightening ad group themes so your ads are more relevant to the specific keywords triggering them, and ensuring your landing page content closely matches the intent of the search. A page that clearly delivers what the ad promised will always outperform a generic homepage.

Review your search terms weekly

The search terms report is where budget leaks happen. A keyword that looks sensible in your account can trigger a wide variety of actual searches — some highly relevant, some completely irrelevant. Reviewing this report weekly and adding negative keywords based on what you find is one of the highest-value activities in any PPC account.

Set a recurring calendar reminder for this task. Ten minutes per week here consistently outperforms sporadic hour-long review sessions.

Test your ad copy systematically

Most PPC accounts run the same ad copy for months without testing alternatives. This is a significant missed opportunity. Running two or three variants per ad group — testing different value propositions, calls to action, or ways of expressing the same benefit — reveals what your specific audience responds to.

The rule is to change one element at a time so you know what caused any difference in performance. Pause underperformers once you have statistical confidence and replace them with new tests. Over time this process compounds into substantially better click-through and conversion rates.
