Check if URL is indexed by Google using PHP

Question

I would like to know if it\'s possible to check if URL is indexed by Google using PHP.

Is this against their ToS?

Answer 1

Well, not explicitly. But you can check every page view using:

$agent = $_SERVER['HTTP_USER_AGENT'];

if (strstr($agent, 'googlebot')){

  // tell the database that google has crawled this page.
}
