Google Grabber — Using PHP to Find Out How Many Pages Your Domain Has Listed in Google

Most bloggers make an effort to get as many pages listed on Google as possible. Benefits of being listed in Google may include:

• Increased blog visits
• Increased ad clicks
• Broadened visitors / audience
• Increased article comments
• Increased referral revenues

Using a short amount of PHP code, you can query Google to retrieve the number of pages your domain has listed in Google.

The Code

/* return result number */
function get_google_results($domain = 'davidwalsh.name')
{
 // get the result content
 $content = file_get_contents('http://www.google.com/search?q=site:'.$domain);

 // parse to get results
 $result = get_match('/Results <b>(.*)from/isU',$content);

 // split the results
 $split1 = explode('of about',$result);

 // return result
 return $split1[1] ? strip_tags($split1[1]) : 0;
}

/* helper: does the regex */
function get_match($regex,$content)
{
 preg_match($regex,$content,$matches);
 return $matches[1];
}

The Usage

/* do it! */
echo 'davidwalsh.name: '.get_google_results('davidwalsh.name'); // 164
echo 'digg.com: '.get_google_results('digg.com'); // 3,790,000
echo 'google.com: '.get_google_results('google.com'); // 19,300,000
echo 'cnn.com: '.get_google_results('cnn.com'); // 2,180,000
echo 'imdb.com: '.get_google_results('imdb.com'); // 19,000,000
echo 'dzone.com: '.get_google_results('dzone.com'); // 484,000
echo 'fark.com: '.get_google_results('fark.com'); // 7,390
echo 'some-domain-that-doesnt-exist.com: '.get_google_results('some-domain-that-doesnt-exist'); // 0
