"Last week,I reported on January 15th of a Google Search ranking update with a lot of heated volatility. Truth is, it went through the weekend, but now it is spiking back up again as of yesterday and today - January 20th and 21st. It seemed like whatever kicked in last week around the 15th burned through the weekend. And now, we are seeing even more spike in volatility and pretty insane chatter from the SEO community."
"As a reminder, we had unconfirmed Google ranking volatility on start on January 15th, and January 12th and January 6th. Prior to that, we had the Google December 2025 core update kick off on December 11, 2025 at around 12:25 pm ET and ended on December 29, 2025 at around 2:05 pm ET. It had two spikes, one on December 13th and the other on December 20th."
"Same. They've set a website traffic cap, and no matter how hard you try, it won't go beyond that. New articles aren't even shown in Discover, News, or even search. What's happening now isn't even an update, it's something worse. Same here. Semrush shows volatility spikes again I've been noticing a lot of spam comments in various languages lately. Clearly Google is no longer displaying what/how it should."
Google Search experienced a December 11–29, 2025 core update with spikes on December 13 and 20. Unconfirmed ranking volatility appeared on January 6, 12 and 15, and intensified again on January 20–21. Multiple tracking tools, including SimilarWeb, Advanced Web Rankings, Accuranker, Data For SEO and CognitiveSEO, show increased fluctuation and aggregated charts reflect spikes. Site owners report severe traffic drops, apparent traffic caps, reduced visibility in Discover, News and Search, and a surge in spam comments. Community reports speculate these movements may be adjustments to the December core update, though the exact cause remains uncertain.
