Hack: Installing Rel=Nofollow in PHPAdsNew
If you use PHPAdsNew to serve ads on a relatively low FBPR (foolbarPR) website and your site is suffering from supplemental problems, installing rel=nofollow on your ad links is a tiny tweak that will help tighten your internal links and get some pages back into Google’s main index:
around line 366 in libraries/lib-view-main.inc.php, just before these lines:
// Return banner
return( array(’html’ => $outputbuffer,
$outputbuffer = preg_replace(”/<a href/i”, “<a rel=’nofollow’ href”, $outputbuffer);
I’ve only tested this on HTML banners (a combination of image and text), so your mileage may vary.
Although some SEOs disregard the role of PageRank in combating supplemental pages, its something you do not want to rule out when looking for solutions.
