The manual way comes first, in Google Ads itself. Then the same problem as Goldbeater finds it, every day, without anyone asking.
What learning is, and what resets it
A Smart Bidding strategy shows Learning while it calibrates to a new objective. Hover over the status and Google Ads gives one of these reasons:
- New strategy: the strategy was recently created or reactivated.
- Setting change: a setting for the bid strategy was changed.
- Composition change: campaigns, ad groups or keywords were added to it or removed from it.
- Ad group target change: in some cases, on Shopping campaigns.
How long it lasts depends on how many conversions the campaign gets, how long your conversion cycle is (the time from a click to a conversion), and the strategy. In Google’s words, “It can take a few conversion cycles (1-2 typically) for the bid strategy to calibrate to the new objective.” Manual CPC has no learning period. Other pages of Google’s give the same wait in days and weeks, which the guide to how long Google Ads takes to work sets side by side. The Smart Bidding guide covers which strategies are Smart Bidding and what each needs before it works.
Meanwhile, Google says key metrics may vary, “so you may not want to measure performance until the learning period is over.” That is the cost of changing it again too soon. The second change is made on numbers Google says not to judge yet, and it starts the clock again. A strategy changed every few days never settles, and nobody sees what it would have done.
A changed target is a case of its own. Google’s page on how its bidding learns says changing a target won’t trigger a Learning status, and that the bidding reacts to a new one at once. Its value-based bidding page says changes inside a conversion cycle still make the bidding harder to assess, and that a target changed often mid-cycle could impede performance, since the bidding is handed several targets and may take longer to reach yours. So whatever the status reads, a second change inside the cycle is made on numbers that aren’t in yet. The Target ROAS guide covers how long to wait.
How to find what reset it
- In Google Ads, open Campaigns and add the Bid strategy type column if it isn’t there: the columns icon, Modify columns, then Attributes. Portfolio strategies are under Bid strategies in the Tools menu, with a Status column.
- Hover over a Learning status to see which of the reasons above applies.
- Open Change history within the Campaigns menu, pick the campaign, and filter the list by type of change to see the bidding changes.
- Count the days in the last two weeks on which the strategy or its target changed. Two or more usually means a change landed before the one before it had settled.
- Read the User column. A change made in Google Ads shows the email address of the person who made it, and one made through the API shows “Google Ads API” or the tool’s name.
Google can change targets too. Once auto-apply is on, “Adjust your CPA targets,” “Adjust your ROAS targets” and “Set a target CPA” are among the recommendations it applies by itself. The History tab under Auto-apply settings, on the Recommendations page, lists what it applied.
How to let it settle
- Make one change, then wait. Leave it one to two conversion cycles before judging it or changing it again. Of target ROAS, Google says “the bidder will react immediately but will need some time to hit the new target (give it 1-2 conversion cycles).”
- Move in steps. For more volume from a target ROAS strategy, Google suggests reducing the target gradually, which lets it enter more auctions: a step, a wait, then the next step.
- Turn off auto-apply for bidding if it’s moving your targets: Recommendations, then Auto-apply settings, untick the recommendation, and save.
- Agree who changes bidding. The User column in change history shows every hand on it.
When learning isn't why impressions stopped
Google describes learning as minor performance fluctuations. If a campaign’s impressions fell to nothing, look elsewhere first:
- The target. Google warns that a target ROAS set too high “may limit the amount of traffic your ads may get,” and that a target CPA set too low “may cause you to forgo clicks that could result in conversions.”
- The status. Limited means inventory, bid limits, budget or the strategy itself is holding it back. Misconfigured means the conversion setup, or a budget shared with campaigns on other strategies, is wrong.
- The budget and the ads. A spent budget or disapproved ads stop impressions whatever the strategy is doing.
What Goldbeater shows you
Every day Goldbeater reads the last 14 days of your account’s change history for campaigns, and counts the days on which a serving campaign’s target ROAS, target CPA or bidding strategy changed. Changes made minutes apart count as one day. Two days is a finding, and three or more is high. Budget and status edits aren’t counted.
Each day it lists what the bidding was and what it became, from the change history’s own before and after. Where auto-applied recommendations made some of the changes, the finding says so. It drafts no change, since the fix is to stop changing things, and it names a day to leave the bidding alone until: two weeks after the last change.

A campaign's bid strategy or its target changed on two or more days in the last two weeks. Google says a change inside a conversion cycle makes the bidding harder to assess, and that a target changed often mid-cycle may take longer to reach. A changed strategy also goes back into learning, and results can swing while it learns. So one changed this often never settles long enough to judge.
Google's auto-applied recommendations made some of these changes. Turn off auto-apply for bidding recommendations in Google Ads, then leave Sofas — Phrase's bidding alone until November 23, so it can settle before anyone judges it.
