I have a beautiful, custom-content niche site. I was successful for two glorious weeks in buying Adwords traffic at low CPCs because I enjoyed a high quality score. Had great CTRs to an affiliate offer and was already buying a second home in my mind. Alas, it all came to a crashing halt when my Adwords quality scores fell through the floor. Same site, same content - just quality scores dove. The main money-making link on the site was to an affiliate offer - but it was through a PHP redirect (e.g., "whiteteeth.php"). I had used a subdomain redirect before (e.g., whiteteeth.example.com), which at least at the time was working, but I wanted to implement Tracking202 and you can't really do that with a subdomain redirect. The offer also included one of those "Special Offer Good Until ____" php scripts, where it was always good until today. Converted well, that's for sure. In your collective wisdom, did I get shot down because Adwords was able to somehow see through the PHP redirect into the affiliate link? Or because of the "Good Until..." script? The content itself was straightforward blog content, and totally worth the good quality score. Just general information on the niche category. And again, the quality score on the content was 7 for two weeks before diving. I'm 100% sure I got shot because of the affiliate link or the "good until" thing. Don't want to flirt with getting suspended, of course, but even if I do this approach with other offers I wanted to understand where I dropped the ball.
