Google SERP checker using Google AJAX Search API‏

Posted by on Jan 27, 2012 in project | 21 comments

A warning before you proceed: Google hate you when you are using its API for automated position tracking

So.. Google provide us Google AJAX Search API which we can use to fetch Google search result. The bad news is that it only provide maximum 64 search result.
More info about this API, read here: http://code.google.com/apis/ajaxsearch/documentation/reference.html

We’ll use this API to track our domain position on Google SERP for certain keywords, it’s useful to track your SEO progress.

Full main function source code here:

error_reporting(E_ALL^E_NOTICE);
 
//helper function -- file_get_contents using curl
function file_get_contents_curl($url, $referer='', $ua='')
    {
    $ch=curl_init($url);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    if ($referer!='') {
        curl_setopt($ch, CURLOPT_REFERER, $referer);
    }
 
    if ($ua!='') {
		curl_setopt($ch, CURLOPT_USERAGENT, $ua);
	}
 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    $data=curl_exec($ch);
    curl_close ($ch);
 
    return $data;
    }
 
//this is the main function
function g_serp($keyword, $url, $lang='en')
{
	$g_url='http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q='.urlencode($keyword).
			'&rsz=large&userip='.$_SERVER['REMOTE_DDR'].'&hl='.$lang;
 
	for ($i = 0; $i < 64; $i+=8)
	{
		$start=$i;
 
		$referer='http://localhost/'; //change this into your real domain
		$rawdata=file_get_contents_curl($g_url.'&start='.$start, $referer, $_SERVER['HTTP_USER_AGENT']);
		$decoded=json_decode($rawdata, TRUE); //decode as assoc array
 
 
		if (is_array($decoded['responseData']['results']))
		{
 
			$pos = $start;
			foreach ($decoded['responseData']['results'] as $result) {
				if (substr_count(strtolower ($result['url']), $url))
				{
					$res['position']=$pos+1;
					$res['title']=$result['titleNoFormatting'];
					$res['url']=$result['unescapedUrl'];
 
					return $res;
				}
 
				$pos++;
			}
		}
	}
}

The main function is g_serp() and I create one function helper file_get_contents_curl(). The main function use json_decode(), so, your PHP version must be at minimum 5.2. The function designed to stop at first domain match. You can modified yourself so the function continue to search until 64 results (maybe you want to check whether your domain shown more than one on Google SERP).

Parameters explanation

  • $keyword –> the keyword that you want to check. Example: ‘how to upload mp3 to youtube‘
  • $url –> your domain name (without ‘http://’). Example: www.mp32u.net
  • $lang –> target language, different language target might cause different position result. Example (choose one): en, de, fr, id    

Usage example

require_once "gserp.php";
 
$keyword='how to upload mp3 to youtube';
$url='www.mp32u.net';
$lang='en';
 
print_r(g_serp($keyword, $url, $lang));

Array(
    [0] => Array
        (
            [position] => 7
        )
    [1] => Array
        (
            [title] => MP32U.NET - Create simple video from your MP3 and a JPG image
        )
    [2] => Array
        (
            [url] => http://www.mp32u.net/
        )
)

So, as you can see, at this time of writing, mp32u.net rank #7 on Google English (Google.com) on keyword: how to upload mp3 to Youtube

      Di sini stabil2 saja tuh. Klo ndak ada hujan deres yg dtg tiba2, smua baik2 saja. Klo cmn hujan biasa(yg ndak disrtai petir), sinyal jg masih oke.

          Malah ndak aktif lg di online, plg cmn ngecek sesekali doang. Kerja offline jd programmer freelance banyak menyita waktu.
