Every change across your ad accounts, captured and stored permanently. When performance shifts, trace it back to exactly what changed, who changed it, and when.
The problem
CPA spiked on Tuesday. ROAS is down 20%. The client is on the phone.
Nobody opens the platform's change history. Your team pulls up analytics, checks meeting notes, tries to remember who touched what last week. The change history exists, but it is buried, clunky, and not part of anyone's workflow. So the real answer comes down to memory and guesswork.
And even when someone does dig into Google's change log, the data lives in isolation. You can browse it, but you cannot connect it to performance. You cannot access it programmatically beyond 30 days. There is no way to see what changed on the day ROAS dropped and understand whether one caused the other.
This is how every agency operates. It does not have to be.

How it works
Link the Google Ads accounts you want to track. Add them individually or in packs. ChangeTracer starts pulling change data immediately and backfills up to 30 days using Google's API.
Every campaign update, bid adjustment, audience change, and permission modification is logged and stored. No manual tagging. No scripts. It just runs.
Need to know what changed last Tuesday? Search by date, account, user, or change type. Export for client reporting or connect to Looker Studio to add change context to your existing dashboards.
Solution
Google's API only goes back 30 days. ChangeTracer stores everything programmatically from day one, so the history is always there when you need it -- and accessible in ways the native UI never will be.
Find changes by date, account, user, campaign, or change type. Filter and slice the data in ways Google's UI was never built to support. The long-term vision: correlate changes directly to performance shifts in your dashboards.
Connect to Looker Studio to bring change data into your existing dashboards. Or export directly for client reports and internal reviews.
Track user-level changes across all your accounts. When something breaks, you will know if it was a setting change, a bid adjustment, or someone new with access making edits.

Integration
ChangeTracer includes a Looker Studio connector out of the box, with more integrations on the way. You can also pull data through the API for custom reporting setups.
Use it standalone or plug it into your existing workflow.
We are building ChangeTracer with a small group of agency partners. Spots on the waitlist come with founder pricing and direct input on what we ship.
No spam. We reach out when there is something worth seeing.
