Google ranking script !

Hi Guys,

I have been running SERP scripts on one of my sites, but all the sudden the Google Ranking tools has stopped working. I am sure on what is wrong in the code for Google, both Yahoo and MSN works fine. but not G. Can anybody suggest what is prob in the script below.

------------------------
<?php
if ($_GET['url'] != '') {
if ($_GET['keyword'] != '') {
$keywords[0] = $_GET['keyword'];
$url = $_GET['url'];
$keyword_input = $_GET['keyword'];
}
} elseif ($_POST['url'] != '') {
if (strpos($_POST['keyword'],"\n")) {
$keywords = str_replace("\n",",",$_POST['keyword']);
$keywords = explode(",",$keywords);
} else {
$keywords[0] = $_POST['keyword'];
}
$keyword_input = $_POST['keyword'];
$url = $_POST['url'];
}
$i = 0;
if ($keywords[$i] != '') {
while ($keywords[$i] != '') {
$keyword_implode = str_replace(' ','+',$keywords[$i]);
$fetch_url = "http://www.google.com/search?num=50&q=" . $keyword_implode . "&btnG=Search";
ob_start();
include_once($fetch_url);
$page = ob_get_contents();
ob_end_clean();

$page = str_replace('<b>','',$page);
$page = str_replace('</b>','',$page);
//preg_match('/008000\">(.+)<\/font><nobr>/i', $page, $match);
preg_match_all('/<font color=#008000>(.*)<\/font>/', $page, $match);
$r = 0;
$position = '0';
while ($match[0][$r] != '') {
if ($position == '0') {
if (strpos($match[0][$r],$url)) {
$position = $r+1;
}
}
$r++;
}
$google_position = $position;
---------------------------------

The above code searches Google for ranking on a particular keyword. But for some days now it isnt showing up.

Can anybody suggest !

 

2 suspicions...

1. it seems that your script is scraping the results page - maybe google has changed their format slightly... and some of the anchors you are using have changed?

2. i have noticed that for google, after a couple of pages, it sometimes seem to be able to suspect that the search is performed by a script/robot instead of a human... it then pops up image verification which will definitely confuse your script...

i have a similar script for msn - check out my signature...

 

Well my tool is here, which has Yahoo and MSN along with Google.. Its only the results from Google that is getting retrived.
