Brian at Caydel’s SEO Blog has written a post today revealing that Google AdSense is Beta-Testing Keyword-based Ad Filtering that allows publishers to nominate keywords that they don’t want ads about on their sites – a sort of ‘negative’ keyword targeting.
This would help publishers who are getting mis-targeted and irrelevant ads on their sites.
This ‘negative’ keyword targetting has to my knowledge been available to premium publishers for some time now but perhaps this is an indication that it is going to be made available to everyone.
Positive Keyword Targeting
The other type of AdSense keyword targeting that many publishers would like is ‘positive’ targeting where they would be able to submit keywords that their site is about that they would like ads about. Once again this is a feature that I’ve seen AdSense offer to some larger publishers (not just ‘premium’ publishers) who are struggling with ad relevancy however it is not something that I’ve heard they are offering (or planning to offer) other publishers at this point.
