To audit Google Ads, work through nine checkpoints in a fixed order: conversion tracking, account structure, campaign settings, search terms and negatives, Quality Score, wasted spend, bidding, ad copy and extensions, and landing pages. A focused audit takes two to three hours and shows you exactly where your budget is leaking and where the fastest wins are hiding. The order matters, because if your tracking is wrong, every other number in the account is lying to you.
This guide gives you the full checklist we use at Rankite, in the sequence we run it, with the specific reports to open and what a healthy result looks like at each stage. You do not need any paid software. Everything here lives inside the Google Ads interface.
A Google Ads audit is a structured review of an account against a fixed checklist, designed to surface wasted spend, tracking errors, and missed opportunities before they compound. It is not a vague "look around" of the account. It is a repeatable process that moves through tracking, structure, targeting, and creative in a set order and ends with a prioritized list of fixes ranked by impact.
The reason auditing matters is money. Search advertising is not cheap, and small misconfigurations scale. WordStream and LocaliQ, analyzing 13,474 US search campaigns between April 2025 and March 2026, put the average cost per click at $5.42 and the average cost per lead at $66.69. At those prices, a single misplaced broad match keyword can burn through a monthly budget on traffic that never had a chance of converting.
Run a full structural audit every quarter, and a quick health check on tracking and search terms every week. Optmyzr, citing Melissa Mackey of Compound Growth Marketing, recommends auditing at least every quarter so small mistakes do not escalate into costly problems. On top of that cadence, audit immediately whenever performance moves sharply in either direction, because a sudden spike often hides a tracking break, and a sudden drop often hides a policy or budget issue.
The weekly check is lighter: confirm conversions are still recording, skim the search terms report for new junk queries, and glance at spend pacing. The quarterly audit is the deep one where you run every step below. If you have never audited the account, treat the first pass as the quarterly deep dive and block out a half day for it.
This is the framework, in order. Work top to bottom. Each step names the report to open and the healthy result to look for. Do not skip ahead, because each step assumes the one before it is clean.
Nothing else in the account can be trusted until tracking is proven correct. Open the Goals or Conversions section and check the status column. An active conversion action should read Active, not Inactive or No recent conversions. Then run a live test with Google Tag Assistant: click your own ad, complete the action, and confirm the conversion appears. Google notes the conversion linker tag must fire on every page of your site, not only the conversion page, or you will silently lose conversions from users who do not convert on the first visit. Also check you are not double-counting by importing the same conversion from both Google Ads and GA4.
A clean structure makes every other optimization easier; a messy one hides problems. Check that campaigns are separated by objective, brand versus non-brand, and prospecting versus retargeting, so budgets and bidding can be controlled independently. Inside each campaign, ad groups should be tightly themed, ideally a small set of closely related keywords per ad group rather than a sprawling list. If one ad group holds fifty loosely related keywords, no single ad can be relevant to all of them, and Quality Score suffers.
Settings are where money quietly leaks with no obvious symptom. For each campaign, review location targeting (and confirm it is set to "presence" not "presence or interest", which pulls in people merely searching about your area), language, networks (many accounts unknowingly run on the Display and Search Partner networks and bleed budget there), device bid adjustments, ad schedule, and budget. Confirm the campaign is actually spending toward the right goal and is not capped so low it never gathers data.
This is the highest-value step in most audits. Open the search terms report, set the range to the last 90 days, and sort by cost. Read the real queries that triggered your ads. Every irrelevant one (wrong intent, job seekers, DIY researchers, competitor names you do not want) becomes a negative keyword. Broad match keywords without solid negative coverage are the single biggest source of wasted traffic, so this is where you claw back budget fastest. Build negative keyword lists you can apply across campaigns so the cleanup sticks.
Add the Quality Score column to your keyword view and sort ascending. Quality Score runs from 1 to 10 and is built from three parts: expected click-through rate, ad relevance, and landing page experience. It directly affects both your cost per click and your Ad Rank, so low scores mean you pay more for worse positions. Flag every keyword at 4 or below, look at which of the three components is rated "below average", and fix that specific weakness rather than guessing. A keyword scoring 3 on landing page experience needs a better landing page, not a new bid.
Beyond irrelevant search terms, hunt for spend that produces cost but no results. Sort keywords by cost and filter for zero conversions over a meaningful window, then decide whether to pause, lower bids, or rework them. Check for duplicate keywords competing against each other, ad groups spending with no conversions, and geographic or hourly segments that consistently lose money. The prize here is real: WordStream found the average account wastes over a thousand dollars a month, and most of it is recoverable with an afternoon of cleanup.
Match the bidding strategy to the goal and the data volume. Target ROAS suits revenue-driven ecommerce, Target CPA suits lead generation, and manual or maximize-clicks can make sense for new campaigns still gathering conversions. The common mistake is switching to a smart bidding strategy before there are enough conversions to feed it, which leaves the algorithm guessing. Confirm each campaign's strategy fits its objective and that any target CPA or ROAS is realistic against the account's actual history.
Open each ad group and check that it runs at least two to three responsive search ads so Google has options to test. Confirm the ad copy echoes the keyword and the searcher's intent, and that headlines are not all pinned in ways that block testing. Then check assets (formerly extensions): sitelinks, callouts, structured snippets, and call assets should all be present. Each one gives you more space on the results page and typically lifts click-through rate at no extra cost, so a missing set of assets is free performance left on the table.
The click is only half the job. For each key ad, follow it through to the landing page and confirm the page loads fast, works on mobile, and matches the ad's promise. Message mismatch (an ad about a specific service pointing at a generic homepage) kills conversion rate and drags down the landing page experience component of Quality Score. Strong landing pages are also where paid and organic overlap, and improving them lifts both. Our guide on conversion rate optimization best practices covers the page-level changes that move the number most.
Measure your results against current, named benchmarks rather than gut feel. WordStream and LocaliQ, drawing on 13,474 US search campaigns from April 2025 to March 2026, reported an average click-through rate of 6.64%, an average cost per click of $5.42, an average conversion rate of 8.18%, and an average cost per lead of $66.69. Treat these as a rough floor: they mix every industry together, and your specific vertical average matters far more than the blended number.
Benchmarks tell you whether a number is a problem, not what to do about it. If your cost per lead sits well above the average for your industry, that is your signal to dig into the earlier steps: tracking, search terms, and Quality Score are the usual culprits. For a fuller breakdown of what different industries pay, see our guide on how much Google Ads cost.
The fastest route to wasted spend is the search terms report, sorted by cost, over the last 90 days. Read the queries line by line and mark every one that has nothing to do with what you sell. Broad match keywords without proper negative keyword coverage are responsible for most irrelevant traffic in a typical account, which is why negatives are the highest-leverage fix. After that, check for keywords with high cost and zero conversions, duplicate keywords bidding against each other, and Display or Search Partner placements that spend without returning.
Wasted spend is rarely one big leak. It is usually a dozen small ones that add up, which is exactly why WordStream's average of over a thousand dollars a month per account is so common and so recoverable. A disciplined pass through steps 3, 4, and 6 above typically finds it. If you would rather have a specialist run this for you, our complete SEO site audit pairs the paid-search review with the organic and technical picture so nothing falls between the two channels.
Even careful marketers trip on the same few things. Avoid these.
The fix for all of them is the same discipline: run the steps in order, tie everything back to conversions, and repeat on a schedule.
What is a Google Ads audit? A Google Ads audit is a structured review of an account against a fixed checklist to find wasted spend, tracking errors, and missed opportunities. It covers conversion tracking, account structure, campaign settings, search terms, Quality Score, bidding, ad copy, and landing pages, and ends with a prioritized list of fixes.
How long does a Google Ads audit take? A focused audit of a single account usually takes two to three hours once you know the checklist. Large accounts with many campaigns, or accounts you have never reviewed before, can take a full day. The search terms report and conversion tracking checks are where most of the time goes.
How often should you audit a Google Ads account? Run a full structural audit every quarter, with a quick health check on tracking and search terms every week. Optmyzr, citing Melissa Mackey of Compound Growth Marketing, recommends auditing at least every quarter so small mistakes do not escalate into costly problems. Audit sooner if performance suddenly moves up or down.
How do you find wasted spend in Google Ads? Open the search terms report, set the date range to the last 90 days, and sort by cost. Read the actual queries that triggered your ads and add anything irrelevant as a negative keyword. Broad match keywords without negative coverage are the biggest single source of wasted spend in most accounts.
What is a good Quality Score in Google Ads? Quality Score runs from 1 to 10. Anything at 7 or above is generally healthy, 5 to 6 needs work, and 4 or below is dragging up your cost per click. Google calculates it from expected click-through rate, ad relevance, and landing page experience, and it directly affects both your CPC and your Ad Rank.
How do you check if conversion tracking is set up correctly? Check the status column in the Conversions section; an active conversion action should read Active, not Inactive or No recent conversions. Then run a live test with Google Tag Assistant and confirm the conversion linker tag fires on every page. Google notes the conversion linker must fire site-wide, not only on conversion pages, or you lose conversions.
What is the average cost per click in Google Ads? Across 13,474 US search campaigns from April 2025 to March 2026, WordStream and LocaliQ found the average cost per click was $5.42, with an average click-through rate of 6.64% and an average conversion rate of 8.18%. Use these as a rough benchmark, but your own industry average matters far more.
Can you audit a Google Ads account for free? Yes. Everything you need lives inside the Google Ads interface: the search terms report, the recommendations tab, the auction insights report, and the conversions status column are all free. Google Tag Assistant is free for tracking checks. The checklist and the discipline to act on what you find are what actually matter.
Should you act on Google Ads recommendations and the optimization score? Review them, but do not auto-apply them. The optimization score and recommendations often push broad match, higher budgets, and looser targeting that raise Google's revenue more than yours. Treat each recommendation as a suggestion to evaluate against your own goals, and dismiss the ones that do not fit.
Block out two hours, open your account, and run the nine steps in order. Start with conversion tracking, then let the search terms report show you where the money is going. Fix the biggest leaks first, note the smaller ones, and set a recurring quarterly reminder so the account never drifts far again.
