Google’s help page on Smart Bidding learning now says the “Learning” status never lasts more than 7 days
. The page, Google Ads Help answer 13020501, is titled “About Smart Bidding learning”. In a Wayback capture from October 17, the same help article was titled “Duration of the learning period for campaigns and what affects it”. We found no Google announcement of the rewrite. Google’s separate bid strategy statuses page still lists a Learning reason that the new page dropped. We only know the documentation changed, not the product.
How long does Smart Bidding “Learning” last?
Google’s help page now says the Learning status never lasts more than 7 days and has three triggers: a new strategy, a composition change or a goal change. It says performance typically converges to a new goal within 1 to 2 conversion cycles. After that period, its FAQ says to evaluate performance over 2 conversion cycles or a 2 week window (whichever is longer)
, accounting for conversion delay.
What the rewrite changed on the help page
The change window runs from the October 17 capture (11:20 UTC) to Search Engine Roundtable’s report on October 21, which called it a major help document rewrite
. We cannot date it more closely.
| Item | Oct 17 capture | Oct 21 page |
|---|---|---|
| Time limit | No 7-day figure in the archived text | “never lasts more than 7 days” |
| Reasons listed | New strategy, Setting change, Composition change, Ad group target change (“in some cases” on Shopping) | New strategy, Composition change, Goal Change |
| Reason count | Says 3, lists 4 | Lists exactly 3 |
| Convergence | “1-2 typically” conversion cycles to calibrate | “typically converges” within 1 to 2 conversion cycles |
| Evaluation rule | None in the archived text | 2 cycles or 2 weeks, whichever is longer |
What the new page says triggers Learning, and what never does
| Triggers Learning | Never triggers Learning |
|---|---|
| New strategy: recently created or reactivated | Budgets |
| Composition change: campaigns, ad groups or keywords added or removed | Targets |
| Goal Change: conversion goals or actions you optimize to have significantly changed | Creatives, and targeting settings such as location, audience or language |
The page gives no threshold for when goals have “significantly changed”. It also says creating or applying a new portfolio bid strategy is a structural change that can show Learning for up to 7 days.
Two Google pages now disagree
The bid strategy statuses page says you can hover to see which of “4 reasons” applies, then lists three: New strategy, Setting change and Composition change. Its Learning section still links to answer 13020501 under the old title. The rewritten page lists no Setting change and no Shopping ad group target reason. We attribute each page and do not resolve it. We could not check which of the two lists the account UI shows today.
The badge and the result run on different clocks
The new page says the status disappears within 7 days, while performance typically converges to your new goal within 1 to 2 conversion cycles
. Its example is a Target ROAS change from 500% to 400%. The new target applies at once, performance converges over the conversion cycle, and no Learning status appears. A missing badge after a target or budget edit does not mean nothing is in motion. A cleared badge does not mean the result has settled.
Google’s glossary defines a conversion cycle as the time it takes for a click to result in a conversion. For imported conversions, conversion cycles will also include the time it takes for conversions to be reported in your account
. A slow import can therefore stretch the evaluation window. Google’s best practice on the new page is to send offline conversion data frequently and consistently
. The page lists no upload or matching change among its Learning reasons. That includes the change in our piece on Data Manager dropping the SHA-256 requirement on November 16: if your conversion counts move after that date, none of the page’s Learning reasons will flag it, so log the date yourself.
Goal Change is now a named reason on the help page
The page advises optimizing to a single, consistent conversion goal designated as the primary account default goal. Goal Change names a significant change to the conversion goals or actions you optimize to as a cause of Learning. Our earlier piece on multi-source conversions and why imported GA4 conversions are left out covers one way accounts change conversion setup. The new page does not say whether that kind of edit counts as a Goal Change.
What to do with it
This part is our reading, not Google’s.
- Write down the date of every target, budget or goal edit. For target and budget edits, the page says no Learning status appears at all.
- Let the 1 to 2 conversion cycles the page gives for convergence pass, then apply its rule: evaluate over 2 conversion cycles or a 2 week window, whichever is longer.
- Avoid stacking target edits. The page says to avoid
multiple target changes within a single conversion cycle
unless there is a clear business need. - Measure your own cycle from click to reported conversion, including import lag.
