Google has rewritten its help page on Smart Bidding learning. It now says the Learning status lasts seven days at most, and that most everyday edits do not reset it. For advertisers who freeze their accounts every time they see that label, this is useful.
Google has replaced its old help article on how long the bidding learning period lasts with a new page called About Smart Bidding learning. Barry Schwartz of Search Engine Roundtable spotted the rewrite on 21 October 2026 and described it as a major one.
The headline change is a clear limit. Google now states that the Learning status "never lasts more than 7 days". The page also explains what does and does not put a campaign into Learning, adds a short set of best practices and a new FAQ section.
According to the page, only three things put a bid strategy into Learning:
Changing your budget, your target CPA or ROAS, your ads, or your location, audience or language targeting does not trigger Learning. Google says budget and target changes apply from the next auction, and that Smart Bidding does not start from scratch when it already has conversion history. Ads keep serving normally while the label is showing.
Google separates the label from how long results take to settle. It says performance usually adjusts to a new goal within one to two conversion cycles, and recommends judging results over two conversion cycles or two weeks, whichever is longer, after allowing for conversion delay. Clicks, cost per click and click-through rate can move around in the meantime.
This matters to any business using Maximise conversions, Maximise conversion value, target CPA or target ROAS. It matters most to small accounts with modest conversion volumes, where a sale or lead can take days to arrive. These are often the accounts where owners panic in week one and change everything, which only resets the clock.
We like this rewrite because it removes an excuse. "It's still learning" is often used to explain away a weak account for weeks. Now the rule is clear: the label goes after seven days, and only structural changes bring it back.
This week, for a client, we would check that each account has one primary conversion goal that reflects real enquiries or sales, set a two-week review date for every bidding change, and stop splitting small budgets across many campaigns. Patience still matters, but it should be measured in conversion cycles, not guesswork.
