Google 抓取工具基础架构采用先进的算法来确定网站的最佳抓取速度。我们的目标是,每次访问您的网站时都尽可能多地抓取网页,但不会过多地占用服务器的带宽。在某些情况下,Google 抓取您的网站可能会给您的基础架构带来沉重负载,或在服务中断期间产生不必要的费用。为了避免这种情况,您可以决定减少 Google 抓取工具发出的请求数量。

Common causes for increased crawling include inefficient site structure, like faceted navigation. For urgent reductions, return `500`, `503`, or `429` HTTP status codes to crawler requests; this will lower the crawl rate, but can negatively affect site indexing if done for too long. Alternatively, if returning errors isn't viable, submit a special request specifying an optimal crawl rate. Note: reducing the crawl rate will result in slower updates of existing pages.\n"],null,[]]
