How do I stop search engines indexing a maintenance page

I need to setup a maintenance page for a website I'm running, e.g. for display when I'm performing site maintenance (scheduled downtime) or if something really breaks and I need to put up a holding page.

Is there anything special I need to do to ensure that search engine crawlers don't index it and think that it's my site. Or should I do a 404, add a temporary robots.txt file or something? I basically don't want them to index it as my site, but I also don't want them to think my site is dead and not come back.

Edit: Here's what I did in Apache: ErrorDocument 503 /.server-maintenance.html RewriteEngine On RewriteRule !^.server-maintenance.html /server-maintenance Redirect 503 /server-maintenancestrong text

Solution

  • You should send a 503 Service Unavailable HTTP status code, and not a 404. Use this in conjunction with a Retry-After header to tell the robots when to come back.
