Find a conversion setting change that change history doesn't show

When conversions jump and change history shows nothing, find the conversion action and the day its count moved, then compare that action's settings with what you expect: Primary or Secondary, Count, Click-through conversion window and value. If every setting matches, look where the conversion is recorded, such as the Versions page in Tag Manager.
Before you start
- Read-only access or higher to the Google Ads account. Putting a setting back is an edit, which needs Standard or Admin access.
- The rough date the numbers changed, and how many leads a normal week brings, from your own call and form log.
Find the action and the day that moved
Split conversions by action first; Google says count and window changes apply only to conversions from then on, so the jump starts on the day of the change.
- In Google Ads, open Campaigns, set the date range to two weeks either side of the jump, click Segment above the table, then under Conversions choose Conversion action.
- Compare each action's Conversions and All conv. before and after. Conversions holds the actions a campaign's goals use (Primary actions, plus any action in a custom goal); All conv. adds Secondary ones. If All conv. stayed level while Conversions jumped, an action was probably made Primary or added to a campaign's goals. If both jumped, the action is recording more.
- Click the Columns icon and add Conversions (by conv. time). The main column files each conversion under the day of the ad click, so a change can seem to start before it was made.
- Narrow the date range until you find the first day that action changed, and write it down.
Compare the action's settings with what you expect
Google lists edits to conversion actions as a Conversions change type, so filter for them first; if none show, read the settings, because Google also says not every account-level settings change is always listed.
- Open Campaigns, then Change history, set the dates around that day, and click Conversions among the change type filters below the Change overview. If the edit is listed, the related how-to on seeing who changed your account covers undoing it.
- If nothing is listed, click the Goals icon, open the Conversions drop-down and click Summary. Hover over the action to see its value, conversion windows, source, count, attribution model, and whether it is in the Conversions column.
- Compare each with what you expect. Count set to Every instead of One adds repeat conversions from the same click; a longer Click-through conversion window adds conversions that come later.
- On the Goals tab, click Edit goal on each goal holding the action, expand Conversion action optimization and read Primary or Secondary (observe only). Expand Account default to see whether the goal is an account-default goal.
- Look for any action in the list you do not recognize. A new Primary action adds to Conversions from the day it starts recording.
- If the jump is in some campaigns only, open Campaigns, then the Settings tab, and expand Conversion goals to see whether the campaign uses account-default goals or campaign-specific ones, and which.
Putting a setting back does not repair the days in between: Google says count and window changes apply only to future conversions.
Look where the conversion is recorded
If every setting matches, look in the tool that records the conversion, because a tag or a call tracker can change what Google Ads receives without any Google Ads setting changing.
- If the action comes from your website through Tag Manager, open the container and click Versions. Entries with a date in the Published column show when each version went live and who published it. Read the one published closest to your day.
- If the action was created from a Google Analytics event, Google says conversion edits made in Analytics appear in Google Ads change history, and Analytics keeps its own change history with before and after views.
- If a call tracking service sends calls to Google Ads, open its Google Ads integration and confirm which conversion actions each call goes to.
Check it worked
Once the setting or tag is put back, the action's daily count should return to its earlier level. Allow a few days, since conversions can arrive late.
Then copy each Primary action's Count, Click-through conversion window, value and attribution model into a dated note. The next jump can be compared against it.
Why a reporting tool can show no change at all
Google's list of the resource types its API change records cover includes ads, ad groups, campaigns, budgets and assets, and does not list conversion actions. Those records reach back only 30 days, and Google says they may not include every change in the website's change history. So an empty change list in an API-based dashboard proves nothing about conversion actions.
