雖然 Google 用於偵測搜尋結果中垃圾內容的自動化系統一直都在運作,但有時我們會大幅改進這類系統的運作方式,這就是所謂的「垃圾內容偵測系統更新」。當我們這麼做時,也會在 Google 搜尋排名更新清單中分享相關資訊。
舉例來說,SpamBrain 是採用 AI 技術的垃圾內容防範系統,我們會不時改進這套系統,以便更準確地辨識垃圾內容,並確保能偵測到新的垃圾內容類型。
如果網站在我們更新垃圾內容偵測系統後有所變動,網站擁有者應參閱垃圾內容政策,確保網站符合這些政策規定。違反 Google 政策的網站在搜尋結果中的排名可能會降低,甚至完全不會顯示在搜尋結果中。擁有者修改網站後,我們的自動化系統需要幾個月的時間確認網站是否遵循垃圾內容政策,一旦網站符合規範,搜尋成效就有可能提升。

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."]]
