Audit Your Google Ads Account in 5 Steps to Stop Wasting Budget on Invisible Mistakes

Google Ads Audit With Claude
By the end of this guide, you'll be able to run a complete Google Ads audit in under 20 minutes using Claude — catching wasted spend, identifying underperforming keywords, and generating a prioritized action plan you can hand directly to your client or use yourself.
Who This Is For
You're running Google Ads yourself or managing an account someone else set up
You're getting clicks but not conversions and don't know why
You inherited an account and don't know what's broken under the hood
Your cost per conversion keeps climbing and adjusting bids isn't fixing it
You want a quarterly account health check before you scale spend
What You'll Fix
Five structural problems that cause most Google Ads waste — in the order you should fix them:
Conversion tracking errors — duplicate tags inflating reported conversions and corrupting Smart Bidding
Mixed Search + Display campaigns — search budget silently routing to display placements with no purchase intent
Broad match keyword waste — budget going to irrelevant queries with no negative keyword list to stop it
Under-resourced PMAX campaigns — incomplete asset groups limiting auction eligibility
Wrong conversion goals — Smart Bidding optimizing for page views and scroll depth instead of revenue
What You'll Need
An active Google Ads account with spend history
Google Tag Assistant Legacy — free Chrome extension (search "Tag Assistant Legacy" in the Chrome Web Store)
45–60 minutes
Going Further
Monthly Search Terms review — set a recurring calendar reminder to pull the Search Terms report, add new negatives, and check for new waste categories. Broad match evolves constantly.
PMAX asset rotation — after filling asset slots, check asset performance quarterly. Google shows which headlines and images are getting the most impressions. Remove the lowest performers and test new ones.
Conversion tracking audit after any site change — any time you update your website, CMS, or tag setup, re-run Step 1. Tag fires break silently and no one notices until ROAS craters.
