Google Ads Audit Checklist to Improve PPC Performance

If clicks are coming in but leads are weak, costs keep rising, or performance feels “random,” it is usually not bad luck. It is usually something fixable hiding inside your settings, structure, search terms, or tracking. That is exactly what a Google Ads audit checklist is for: a proper health check that spots leaks, wasted spend, and missed opportunities, then gives you a clear action plan. The goal of this post is simple: help you run a Google Ads audit that finds what is killing PPC performance, without getting lost in jargon.

Start with the basics: are you measuring the right thing?

Before touching bids or keywords, make sure the account can measure success correctly. Many performance problems are actually tracking problems.

1) Confirm conversion tracking is truly working

Check that primary conversions are recording properly and are not duplicated.
Verify conversion actions align with real business goals, not vanity events.
Confirm attribution settings make sense for your sales cycle.

If conversion tracking is broken or messy, optimizations can push spending towards the wrong outcomes. In the Adalysis guide, conversion tracking comes first for a reason.

2) Check auto-apply and auto-created assets

Turn off auto-apply recommendations if changes are happening without control.
Review automatic asset creation and keep only what improves results.

Auto changes can quietly shift strategy over time, so this step matters.

Account structure checks: stop fighting your own setup

A strong structure makes it easier to control intent, messaging, and budget. A weak structure forces Google to guess, and it often guesses expensively. This is where your Google Ads audit checklist starts paying for itself.

3) Separate networks properly

Avoid mixing Search and Display in the same campaign.
For Display, exclude sensitive content and review placement suitability.
Exclude mobile app traffic for Display unless it is proven valuable.

4) Review campaign settings that quietly waste spend

Location targeting: ensure “Presence” targeting is appropriate, not overly broad.
Language: match the real audience language needs.
Ad schedule: check if spend is being wasted during low-converting hours.
Budget distribution: make sure priority campaigns are not starved.

Assets (extensions): get more from the same clicks

Assets can improve ad rank and give users more reasons to click. The Adalysis checklist highlights using multiple asset types and having enough of each to test properly.

5) Use at least three asset types

Sitelinks, callouts, structured snippets are a solid baseline.
Keep a minimum quantity so performance data is meaningful (for example, multiple sitelinks and callouts).
Fix disapprovals and partial approvals so assets can serve fully.

Keywords and search terms: the biggest performance killers live here

When people ask “how to audit Google Ads account performance?”, this is often where the answer is. Keywords might look fine, but search terms reveal the truth.

6) Look for conflicts and duplicates

Check if keywords are blocked by negative keywords by accident.
Remove duplicate keywords within the same campaign or ad group.
Find search terms triggering multiple ad groups and tighten intent.

7) Check match types and hygiene

Confirm match types are correctly formatted so traffic behaves as expected.
If ad groups have too many keywords, relevance drops and ads become generic.
Add high-converting search terms as keywords so you can write more relevant ads and landing pages.

This is also where you catch common Google Ads mistakes like broad intent mismatch, messy ad groups, and unfiltered query flow.

8) Confirm negatives exist, and are organised

Ensure Search campaigns actively use negative keywords.
Check negative match type formatting so unwanted queries are actually blocked.
Use shared negative lists where practical to reduce repeats and make management easier.

This step directly supports improving PPC lead quality because it stops irrelevant clicks before they happen.

Landing pages: do not pay for traffic that bounces

Even a perfect ad cannot save a broken or slow landing page.

9) Check the obvious, then the sneaky

Fix broken URLs across ads, keywords, sitelinks, and dynamic landing pages.
Use secure URLs (https) to avoid trust issues and browser warnings.
Review page speed, mobile experience, and message match with keywords and ads.

If your landing page experience is poor, then the quality Score can take a hit. Not only that, but your CPC can also rise, and conversions can fall.

Ads: are you testing properly or guessing?

Ads should be unique, active, and built for learning.

10) Fix ad testing gaps

Remove duplicate ads inside ad groups so testing is real.
Ensure every ad group has active ads.
Keep a sensible number of ads per ad group, often two to three active ads for testing without slowing learning.
Migrate outdated formats and lean into responsive search ad assets, then replace weak assets.

Performance Max: do not let it eat your best Search traffic

Performance Max can work well, but it can also overlap with Search and blur what is driving results. The Adalysis article calls out monitoring search term insights and controlling overlaps with negatives and exact match keywords.

11) Review asset groups and signals

Add audience signals to guide learning.
Improve ad strength by refreshing creative assets.
Watch search term insights and manage cannibalisation risks.

Performance audit: find wasted spend and reclaim it

Once structure is sound, shift to the money side. This is the second half of a proper Google Ads audit.

12) Identify waste with clear thresholds
Set a rule of thumb like “X clicks with zero conversions over Y days” to flag candidates for pausing or bid reduction. Then dig into keywords, search terms, placements, landing pages, and devices to find the losers.

13) Check budget-limited campaigns

Look at “Search lost impression share (budget)”. If it is high, even a strong campaign might be throttled. Estimate upside by combining lost impression share with CTR and conversion rate to forecast extra conversions from extra budget.

This is where core PPC optimization tips matter most: fix leaks first, then scale what already works.
