How to take over a Google Ads account without breaking it

A fixed-order checklist for inheriting a Google Ads account: secure ownership, snapshot everything, audit measurement before campaigns, then change slowly. Includes the checks I run on every takeover.

Take over a Google Ads account in a fixed order: secure ownership and access, snapshot everything, audit the conversion tracking, check the settings that quietly waste money, and only then start changing campaigns, slowly. Accounts break in handovers because the new manager rebuilds structure and bids in week one, before finding out whether the conversion numbers steering everything were real.

I take over accounts for a living, and the same faults show up again and again. Here is the order I work in, and why each step comes where it does.

The takeover order
  • 1Confirm the client owns the account and secure admin access
  • 2Snapshot settings, budgets, bid strategies and change history
  • 3Audit every conversion action before judging any campaign
  • 4Check network settings and the search terms report
  • 5Verify the tags in the page source and the GTM container
  • 6Change one thing at a time, because bidding re-learns slowly

Who should own the account?

The client. Google Ads has three access levels, admin, standard and read-only, and the business paying for the clicks should hold admin on an account it owns, with any manager or agency working through linked access. If you are inheriting an account that the previous agency owns, getting ownership transferred is the first job, before any optimisation. An agency that resists handing it over is telling you something, and is my ads agency doing a good job covers what else to look for.

What should you record before changing anything?

Everything, while it still exists. Export or screenshot the campaign settings, daily budgets, bid strategies, the full list of conversion actions and their settings, and the change history. This costs twenty minutes and buys you two things: a before picture to judge your own work against honestly, and the ability to roll back when a change makes things worse. You can also pull the account's public ad history from the Ads Transparency Center at adstransparency.google.com, which shows every advertiser's ads, last-shown dates and regions with no login, a useful record of what the previous manager was actually running. I explain that tool properly in how to check if a company is running Google Ads.

Why audit conversion actions first?

Because smart bidding, Google's automated bidding, optimises toward whatever the conversion action counts. If the action is broken, the machine has been diligently optimising toward garbage, and every performance number in the account is fiction.

75%

of clicks counted as conversions in one account I took over, because the tag fired on page load

That account looked brilliant on paper. For each conversion action, establish what actually triggers it, and check the counting setting: Google offers one-per-click or every, and lead generation should use one-per-click so a nervous visitor submitting a form twice counts once. The full self-check for whether reported conversions are real is in the three receipts.

Which settings quietly waste money?

Two places. First, networks: a Search campaign can quietly opt into the Display Network and Search Partners through checkboxes in campaign settings. In takeovers I did in 2026, between 43% and 59% of spend was leaking to the Display network as junk placements, mobile games, apps and unrelated websites, on campaigns everyone believed were Search only. Second, match types: broad match keywords expand your reach well beyond what you typed, so read the search terms report to see the actual queries you paid for, and expect to add negative keywords regularly to keep it honest.

How do you verify the tracking actually works?

Without waiting for a developer. View the website's page source and search for gtag, GTM- and AW-, which show you the Google tag, any Google Tag Manager container, and Google Ads conversion IDs. Then open the container itself: every GTM container is publicly readable at googletagmanager.com/gtm.js?id=GTM-XXXX, and you can search that text for AW- to see which conversion tags really exist inside it.

Check before you condemn, though. Of 70 tracking problems I suspected across takeovers, 30 proved false once I looked inside the GTM containers. And if the account was healthy until recently, ask when the website was last relaunched, because relaunches commonly break tags and redirects; that failure pattern has its own page.

How fast should you change things?

Slowly, with one exception. Smart bidding re-learns slowly after changes, so a burst of simultaneous edits both destabilises performance and makes it impossible to tell which change did what. Fix the measurement, then adjust one meaningful thing at a time and let the data settle. The exception is a broken remarketing tag: audiences decay daily while a site is untagged and those days are unrecoverable, so restore tagging immediately even while everything else moves at a deliberate pace.

If you are hiring someone to do all this rather than doing it yourself, how to brief a Google Ads freelancer includes the one interview test that shows whether a candidate would have caught the 75% account.
