Google changes how Google Ads works all the time: how match types match, how bidding spends, which campaign types exist, what runs on by default. Those changes move your numbers, but Google keeps no single dated record of them. This is that record, with a source on every entry.
Scope: platform-level changes that can move an account’s numbers or force a decision (targeting & match types, bidding & budgets, campaign types, automation, reporting, policy, deprecation). This is not your account’s change history, and it does not cover Google Search ranking updates. Entries are written as neutral mechanics; the opinion lives in our Knowledge Base.

Google announced that Dynamic Search Ads would be upgraded to AI Max, moving DSA targeting and creative onto the AI Max system. Advertisers running DSA are transitioned toward AI Max matching and asset generation rather than the previous DSA behaviour.
Google opened AI Max for Search campaigns in open beta, a bundle of AI-driven targeting and creative features layered onto Search campaigns. When enabled, it expands matching beyond the advertiser keywords and lets Google generate and rewrite ad assets, further loosening keyword and copy control in Search.
Through 2024 Google increased pressure on advertisers to adopt broad match with Smart Bidding, presenting it as the way to maximise reach and conversions. Recommendations, Optimization Score, and in-product prompts steered accounts toward broad match and away from tightly controlled keyword lists.
Between July and September 2022, Google automatically migrated existing Smart Shopping and Local campaigns into Performance Max. Advertisers who used those campaign types were moved onto PMax and its reduced transparency and controls whether or not they opted in.
As of June 30, 2022, expanded text ads can no longer be created or edited, leaving responsive search ads as the only ad type buildable in standard Search campaigns. Existing ETAs keep serving and reporting, but advertisers lose the fully hand-written, fixed ad copy that ETAs provided.
Google switched the default ad type in the campaign creation flow from expanded text ads to responsive search ads. RSAs let Google assemble headlines and descriptions dynamically at auction time, moving control over the final ad copy from the advertiser to the system.
Performance Max launched to all advertisers as a single campaign type that runs across Search, Display, YouTube, Gmail, Maps, and Discover with Google AI controlling targeting, bidding, placements, and creative assembly. It offers no keyword-level control and limited visibility into which queries and placements drive results.
Google began actively recommending broad match combined with Smart Bidding over exact and phrase match, arguing the pairing finds converting queries that tighter match types miss. The guidance shifted advertisers away from the granular keyword control that exact and phrase provide.
From July 2021, new broad match modifier keywords could no longer be created, and existing BMM keywords served under the new phrase match behaviour. Advertisers who relied on BMM for controlled matching had to move to phrase match and add negative keywords to hold back the wider matching.
Google launched auto-applied recommendations, letting the platform automatically apply changes from the Recommendations tab such as bidding, keywords, and ad suggestions. Accounts can be enrolled in categories that then change settings without a manual review, so advertisers need to check the setting and opt out of anything they do not want applied.
Google announced that broad match modifier (the +keyword notation) would be phased out and its matching behaviour folded into phrase match. Phrase match became broader as a result, matching more queries and ignoring word order in more cases, while the granular BMM control disappeared.
The same-meaning close variant behaviour introduced for exact match was extended to phrase match and broad match modifier keywords. Phrase and BMM keywords started matching queries that shared intent rather than requiring the literal terms.
Exact match began matching queries that share the same meaning as the keyword, including implied words and paraphrases, not just close spelling variants. This widened the range of queries an exact keyword could trigger for.
Exact match was expanded to match queries with reordered words and added, removed, or changed function words (such as "to", "for", "in") when the meaning stayed the same. A keyword like [shoes for men] could now match "mens shoes".
Google began matching exact and phrase keywords to close variants such as misspellings, singular and plural forms, stemmings, and abbreviations. Advertisers lost the ability to opt out of close variants, so keywords started matching queries beyond their literal wording.
