在网站上提供维护页面，会影响Google索引？

Question

我不认为这是一个问题，但我的合作伙伴担心只需服务于24小时的维护页面（因为我们需要恢复数据库，就像意外删除的数据库一样）它可能对我们的谷歌产生负面影响索引/评级？

Answer 1

I would follow Google’s recommendations on blacking out your website to protest SOPA. Specifically:

1. Return a 503 Service Unavailable status code for pages which are unavailable.
2. Make sure that robots.txt does not return a 503 status code.

Answer 2

I believe the best way to deal with this is throwing an error code 503 Service Unavailable and use a custom error document to style it more friendly.

Answer 3

You could exclude it from crawlers like Google's by using a robots.txt file in the root of the site for that 24 hour period.

Answer 4

to be sure that there are no problems, you should serve your page using the 503 Service Temporarily Unavailable status. Retry-After can also be set, but i am not sure if the google crawlers care about that.
