been digging through sistrix data for us and uk domains to see what actually moved between may 26 and june 2. the rollout was active from may 21 to june 2, and the shifts aren't just random noise. looking at the biggest winners, it seems like intent and how well a site matches the specific market are the main drivers here. it is not just about backlink profiles or
old school seo authority anymore. instead, the big visibility swings are coming from changes in
source type and deeper alignment with user needs.
>the biggest shifts happened when the content matched the underlying intent perfectlyit feels like google is getting much more aggressive at filtering out sites that have the right keywords but the wrong purpose for the query.
it is basically a massive purge of low-utility pages . i am seeing a lot of movement in how specific types of sources are being prioritized over generalist sites. has anyone else noticed their rankings tanking despite having no technical errors or lost links? it looks like the
market fit aspect is becoming the new king of the core updates.
