I'm starting this log now rather than waiting until it has a long history, because I think a genuinely maintained tracker is more valuable started imperfectly than delayed until it feels comprehensive.
Why a Living Tracker, Not a Static Article
Most content explaining AI Overview changes gets published once and goes stale within months, still ranking and getting read long after the specific details it describes have shifted. I'd rather maintain one page honestly, updated as real changes happen and confirmed, than let stale, outdated specifics sit indefinitely under a plausible-looking publish date.
May 2026: AI Overviews and AI Mode Announced as Merging
Google announced AI Overviews and AI Mode are being unified into what it called "one seamless AI Search experience," with users able to move from a quick Overview into a deeper AI Mode conversation without a hard interface break. This is an ongoing transition rather than a completed one, covered in full detail in Google AI Mode vs. AI Overviews, including the important caveat that citation behavior between the two surfaces hasn't fully converged even as the user interface has started to.

The Broader Pattern Worth Tracking, Not Just Individual Updates
Beyond any single dated change, the pattern worth watching is the general direction: AI Overview prevalence has grown substantially since its 2024 launch, citation mechanics have decoupled further from traditional organic ranking over time, and Google continues iterating on how AI Mode and AI Overviews relate to each other and to classic search. I'll log specific, confirmed changes here as they happen, but the direction itself, not any single update, is what should actually inform long-term AEO strategy.

How to Use This Page
Check the "last updated" date at the top before relying on anything here as current, and treat older entries as historical record rather than present-tense fact. If you're making a specific strategic decision based on a claim here, verify it's still accurate given how much time has passed since the entry was logged, algorithm behavior in this space has moved fast enough that even a few months can matter.
What Gets Logged Here vs. What Doesn't
How has AI Overview affected your or clients' organic traffic quality?

I'm logging confirmed, meaningful changes to AI Overview or closely-related algorithm behavior specifically, not every minor interface tweak or unconfirmed rumor circulating in industry discussion. The bar for an entry is: is this a real, confirmed shift that would actually change how someone should think about AEO strategy, not just a small formatting change with no real strategic implication.
