== Display Custom Content to Search Engine Visitors ==

Display custom content to your search-engine traffic by placing the following code into your theme’s functions.php file:

  <?php function scratch99_fromasearchengine() {
  
	$ref = $_SERVER['HTTP_REFERER'];
	$SE  = array('/search?', 'images.google.', 'web.info.com', 'search.', 'del.icio.us/search', 'soso.com', '/search/', '.yahoo.');
	
	foreach($SE as $source) {
		if(strpos($ref, $source) !== false) return true;
	}
	return false;
  } ?>

After checking and editing the $SE array with the search-engine referrer information of your choice, place this next chunk of code into the desired display location in your theme file(s):

  <?php if(function_exists('scratch99_fromasearchengine')) {
	if (scratch99_fromasearchengine()) {
  
		// INSERT YOUR CODE HERE
  
	}
  } ?>
