Google Ads Audit Checklist

A Google Ads audit is a systematic review of your account to find wasted spend, missed opportunities, and problems dragging down performance — and it's one of the highest-value exercises in PPC, because accounts accumulate waste and drift over time without anyone noticing. Whether you run it regularly on your own account or when taking over a new one, an audit checklist ensures nothing gets missed. Here's a Google Ads audit checklist: what to check, why, and how to turn findings into improvements.

Why audits matter

The reason regular audits are so valuable: Google Ads accounts accumulate waste and drift silently — negative keywords go unadded, underperformers keep spending, settings drift, tracking breaks, opportunities go unseized, and budget bleeds on searches that never convert, all without announcing itself. An audit is the deliberate look that catches this: finding the wasted spend to cut and the opportunities to seize, often uncovering significant savings and gains that were quietly there all along. This matters because PPC's continuous, automated spending means small inefficiencies compound — a bit of wasted spend here, a missed optimisation there, adds up to real money over time. Audits also matter when taking over an account (inheriting someone else's account demands an audit to understand its state, find its problems, and know what to fix). And they're the mechanism of ongoing optimisation — regular auditing is how you systematically keep an account healthy and improving rather than letting it decay. Whether periodic on your own account or upfront on a new one, the audit is how you find and fix what's silently costing you — one of PPC's highest-return habits.

The audit checklist

The key areas a thorough Google Ads audit covers: conversion tracking (first and foremost — is conversion tracking set up, accurate, firing, and tracking the right actions? because if tracking is broken, everything else is built on sand); account structure (is the structure logical, with tight themed ad groups and query-to-ad-to-page relevance?); wasted spend and search terms (review search term reports for irrelevant searches to add as negatives — often the biggest waste-cutting opportunity); keywords and match types (are match types appropriate, keywords performing, and negatives robust?); Quality Score and relevance (low Quality Score keywords signalling relevance problems to fix); ads and extensions (are ads strong and tested, and all relevant extensions in use?); bidding and budget (is the bidding strategy right for goals, and is budget allocated to winners?); landing pages (do ads point to relevant, converting landing pages?); campaign settings (targeting, location, scheduling, networks, and settings correct?); performance and metrics (what the metrics reveal about what's working and what isn't); and opportunities (untapped keywords, campaign types, or improvements). Work through these systematically, and the audit surfaces both the waste to cut and the gains to make.

Turning the audit into improvements

The practices that make audits drive results: use a checklist systematically (work through all the areas above so nothing's missed — an audit is only as good as its coverage); prioritise by impact (fix the biggest issues first — broken conversion tracking, major wasted spend, and starved winners typically deliver the most — before minor tweaks); act on findings (an audit that identifies problems but doesn't fix them is wasted — turn each finding into a concrete change: add the negatives, reallocate the budget, fix the tracking, improve the pages); quantify the opportunity (estimate what fixing each issue saves or gains, to prioritise and demonstrate value); audit regularly, not just once (make auditing a recurring discipline — quarterly, say — since accounts keep drifting and accumulating waste, so ongoing audits keep the account healthy, per the continuous-optimisation mindset); audit after major changes (site changes, migrations, and big account changes are when things break — audit then, especially tracking); and document and track (record what you found and fixed, so you can measure the improvement and avoid repeating issues). A systematic, acted-upon, regular audit is how you keep PPC efficient and improving — cutting the silent waste and seizing the missed opportunities, turning ad spend into better results alongside the authority you build (our half).

Frequently asked questions

What is a Google Ads audit?

A systematic review of your account to find wasted spend, missed opportunities, and problems dragging down performance — covering conversion tracking, account structure, wasted spend and search terms, keywords and match types, Quality Score, ads and extensions, bidding and budget, landing pages, settings, and performance. It's valuable because accounts accumulate waste and drift silently over time, so an audit is the deliberate look that catches what's quietly costing you — often uncovering significant savings and gains. Run it regularly on your own account, or upfront when taking over a new one.

What should a Google Ads audit checklist include?

Start with conversion tracking (is it accurate and firing? — everything depends on it), then account structure, wasted spend via search term reports (add negatives), keywords and match types, Quality Score, ads and extensions, bidding and budget allocation, landing pages, campaign settings, and performance metrics — plus untapped opportunities. Work through them systematically so nothing's missed, then act on the findings, prioritising by impact.

How often should I audit my Google Ads account?

Regularly — quarterly is common — because accounts keep drifting and accumulating waste (unadded negatives, drifting underperformers, breaking tracking), so ongoing audits keep the account healthy and improving rather than decaying. Also audit after major changes (site changes, migrations, big account changes are when things break — especially tracking), and upfront when taking over a new account. Make auditing a recurring discipline, act on the findings (prioritising by impact), and document what you fixed — the continuous optimisation that keeps PPC efficient, turning ad spend into better results alongside the authority you build (our lane).
