In an effort to better target the ads that appear on my site, I've gone through most pages on my site and noted which ads I don't want, and added their URLs to my competitive ad filter. FYI I did NOT click any links, I merely looked at the URLs in the ads. Yes, that may not be the purpose of the filter, but it works, and it was my only resort because the google_ad_section tags weren't working. Anywho, like I said, it's working great for my banner ads, but the text link ads are still pulling the same stuff from before. So do text links not use the filters, or does it take longer to apply, or ??
Any URLs on your filter list will also be filtered from the link unit ad pages users are brought to after clicking on a topic. However, you cannot currently filter the topics themselves. Hope that clarifies!
