Google has launched SpamBrain back in 2018 and we have been continuously improving its performance since then. By 2021, SpamBrain was able to identify nearly six times more spam sites than in 2020. This resulted in a significant reduction in hacked spam (70%), which was a common type of spam observed in 2020, and gibberish spam on hosting platforms (75%). SpamBrain is an AI-based spam-prevention system that was designed to be a robust and evolving platform that addresses all types of abuse.

Why is it important?
Google has completed December 2022 link spam update as of January 12, 2023. The update will leverage the power of SpamBrain to neutralize the impact of spam links on search results. According to Google, SpamBrain can detect both sites buying links, and sites used for the purpose of passing outgoing links.
What this update means for website SEO?
It is important to note that rankings may change as efforts are made to neutralize spammy links, resulting in the loss of credit passed by these unnatural links. This launch will impact search in all languages. Google has always emphasized that links obtained primarily for the purpose of artificially manipulating search rankings are considered link spam.
The algorithms and manual actions work to nullify these unnatural links on a large scale and efforts will continue to improve coverage.
