Google 如何檢索會自動調整語言代碼的網頁
如果您網站中的網頁會「自動調整語言代碼」(亦即網站會判斷訪客所在的國家/地區或語言偏好，並依此傳回不同內容)，那麼 Google 可能不會為所有語言代碼的內容進行檢索、排名或建立索引。這是因為 Googlebot 檢索器的預設 IP 位址會顯示為位於美國，而且檢索器傳送 HTTP 要求時也不會在要求標頭中設定 Accept-Language。
地理區域分散式檢索作業
除了美國 IP 位址之外，Googlebot 也會使用位於美國以外地區的 IP 位址進行檢索。
我們向來推薦的做法是，無論 Googlebot 顯示為來自哪個國家/地區，都將 Googlebot 視為該國家/地區的一般使用者處理。也就是說，如果您禁止位於美國的使用者存取內容，但允許位於澳洲的訪客查看內容，那麼您的伺服器應該封鎖具有美國 IP 位址的 Googlebot，同時允許具有澳洲 IP 位址的 Googlebot 存取內容。

This is because the default IP\naddresses of the Googlebot crawler appear to be based in the USA. In addition, the crawler\nsends HTTP requests without setting `Accept-Language` in the request header.\n| **Important** : We recommend using separate locale URL configurations and annotating them with [`rel=\"alternate\"`\n| hreflang annotations](/search/docs/specialty/international/localized-versions).\n\nGeo-distributed crawling\n------------------------\n\nGooglebot crawls with IP addresses based outside the USA, in addition to the US-based IP addresses.\n\nAs we have always recommended, when Googlebot appears to come from a certain country, treat\nit like you would treat any other user from that country. This means that if you block\nUSA-based users from accessing your content, but allow visitors from Australia to see it,\nyour server should block Googlebot if it appears to be coming from the USA, but allow access\nto Googlebot if it appears to come from Australia.\n\n### Other considerations\n\n- Googlebot uses the same user agent string for all crawling configurations. Learn more about the [user agent strings used\n by Google crawlers](/search/docs/crawling-indexing/overview-google-crawlers).\n- You can [verify Googlebot\n geo-distributed crawls](/search/docs/crawling-indexing/verifying-googlebot) using reverse DNS lookups.\n- If your site is using the [*robots exclusion protocol*](https://www.rfc-editor.org/rfc/rfc9309.html), make sure you apply it consistently across locales. This means that [robots `meta` tags](/search/docs/crawling-indexing/robots-meta-tag) and the [robots.txt file](/search/docs/crawling-indexing/robots/create-robots-txt) must specify the same rules in each locale."]]
