This page is a living record of SEO algorithm updates — every confirmed and unconfirmed Google core, spam and Discover update, plus Bing changes, AI-search features, guidance and tooling. Each entry explains what changed and how it affects website owners, with sources you can verify. It is refreshed every 15 days.
Guidance, volatility, tooling, AI features & Bing
Microsoft Bing tested a refreshed news section in its search results and shipped updates to its AI reporting/analytics. Lower-impact than Google's core updates, but worth tracking for brands that monitor Bing visibility and its expanding AI-answer surfaces.

Trackers and forums flagged a sharp, unconfirmed Google ranking movement around Friday June 19 that several SEOs believed disproportionately hit black-hat and manipulative sites. Google didn't confirm it, and volatility had been elevated through mid-June.

Google fixed and updated the long-buggy Search Console link report, restoring more reliable internal and external link data. Not a ranking change, but it improves the data SEOs rely on to audit link profiles and diagnose movement after updates.

At Search Central Live Sydney, Google's Gary Illyes warned against buying or manipulating brand mentions to appear in AI Overviews and AI Mode, comparing the tactic to paid links that Google's systems detect and ignore. Whether authentic mentions directly help AI search wasn't confirmed.
“compared the practice to paid links.”

Google added a “Preferred Sources” option and a new carousel to AI Mode and AI Overviews, letting users influence which publishers appear in AI answers. For site owners it's another sign that visibility inside AI features is becoming its own discipline alongside classic rankings.

Grokipedia continued losing visibility across both Google's organic results and AI search surfaces — a reminder that large, automated content repositories aren't guaranteed durable rankings and can decline sharply as quality systems re-evaluate them.

Google clarified why broad core updates take weeks to fully roll out, pointing to the staged, system-wide re-evaluation of content quality at scale. Useful context for site owners trying to read week-to-week ranking movement during a live rollout.

SEO observers noted Google again appeared to target self-promotional “best of” listicles — a tactic some brands and LLM-generated pages use to rank themselves atop their own roundups. Sites leaning on this pattern saw renewed ranking volatility.

No major confirmed DuckDuckGo algorithm updates surfaced in this window. DuckDuckGo largely relies on Bing's index for its results, so Bing's changes are the more meaningful signal to watch for DuckDuckGo visibility.
Broad core, spam & Discover core updates
Google began rolling out its second spam update of 2026 worldwide and across all languages, refining the automated systems — including SpamBrain — that detect spam. No new spam policies came with it. If your rankings or traffic shift in the following days, review Google's spam policies before assuming another cause.
“applies globally and to all languages.”

Google's second core update of 2026 rolled out with heavy, sustained ranking volatility and several weekend spikes, and many practitioners judged it stronger than March's. Google framed it as a routine update to better surface relevant, satisfying content, with no update-specific recovery steps beyond its standard core-update guidance.
“March was meh, but May is big.”

The year's first broad core update recalibrated quality signals around information gain, originality, first-party data and E-E-A-T, with domain-level authority outweighing page-level optimization. It was highly volatile: SE Ranking data showed roughly 80% of top-three results shifting and about a quarter of top-10 pages dropping out of the top 100.

Google's first spam update of 2026 updated its automated spam-detection systems and finished in under a day — the fastest spam rollout on record. No new spam policies were announced, so existing spam policies remained the framework for judging any ranking impact. It rolled out a day before the March core update began.
Google released a broad core update to the systems that surface articles in Google Discover, reshaping which content appears in the feed by rewarding originality and demonstrated topical expertise while reducing clickbait. Discover traffic can rise or fall; many sites see no change. Standard core-update guidance applies.
“more useful and worthwhile.”

Major updates (right) are the broad core, spam and Discover updates most likely to move your rankings. Minor updates (left) cover guidance, volatility, tooling and AI features worth tracking but lower-impact. When you see movement, match the dates here against your analytics before assuming a technical cause — then review Google's core and spam guidance rather than chasing a single fix.
