Admob Analytics speedup the page load with external analytics script.

[GumSlone]

if you include the admob analytics php code into your site pages the page execution time will be about 1 second or more longer than usually, but if you imagelink to the analytics code, the page execution time will be fast as normal.

so create an extra script eg. analytics.php
and put this code into it:

header("Cache-Control: no-cache, must-revalidate");            // Prevent caching, HTTP/1.1
header("Pragma: no-cache");

$admob_params = array(
  'ANALYTICS_ID'      => 'a14b488d25044ee', // Required to collect Analytics data. To find your Analytics ID, log in to your Analytics account and click on the "Edit" link next to the name of your site.
  'ANALYTICS_REQUEST' => true, // To enable the collection of analytics data, set to TRUE.
  'TEST_MODE'         => false, // While testing, set to TRUE. When you are ready to make live requests, set to FALSE.
  // Additional optional parameters are available at: http://developer.admob.com/wiki/AdCodeDocumentation
  'OPTIONAL'          => array()
);

admob_request($admob_params);

header("Content-type: image/png");
$im = @imagecreate(1, 1);
$background_color = imagecolorallocate($im, 255, 255, 255);
imagepng($im);
imagedestroy($im);


function admob_request($admob_params) {
  static $pixel_sent = false;

  $ad_mode = false;
  if (!empty($admob_params['AD_REQUEST']) && !empty($admob_params['PUBLISHER_ID'])) $ad_mode = true;

    }
    fclose($request);
  }
  else {
    $contents = '';
  }

}

?> 

and link with image tag to it:

<img src="http://yoursite.com/analytics.php" alt=""/>

or php:

echo '<img src="http://yoursite.com/analytics.php?request_uri='.$_SERVER['REQUEST_URI'].'" alt=""/>';

And what's better php or just image?

[GumSlone]

And what's better php or just image?

of cause image because your site pages will load much faster.

And what's better php or just image?

image will load separately so wont affect current execution of page.

Tnx Gum, if that works, i can analise all my static xhtml pages too ;)
