When we\ndo, we refer to this as a *spam update* and share when they happen on our\n[list of Google Search ranking updates](https://status.search.google.com/products/rGHU1u87FJnkP6W2GwMi/history).\n\n\nFor example, [SpamBrain](/search/blog/2022/04/webspam-report-2021) is our\nAI-based spam-prevention system. From time-to-time, we improve that system to make it better\nat spotting spam and to help ensure it catches new types of spam.\n\n\nSites that see a change after a spam update should review our [spam policies](/search/docs/essentials/spam-policies)\nto ensure they are complying with those. Sites that violate our policies may rank lower in\nresults or not appear in results at all. Making changes may help a site improve if our\nautomated systems learn over a period of months that the site complies with our spam policies.\n\n\nIn the case of a link spam update (an update that specifically deals with link spam), making\nchanges might not generate an improvement. This is because when our systems remove the effects\nspammy links may have, any ranking benefit the links may have previously generated for your\nsite is lost. Any potential ranking benefits generated by those links cannot be regained."]]
