Is Google AdSense Losing Its Relevance?
Google AdSense is known for its uncanny relevance in serving context sensitive ads. Its competitors like Yahoo Publisher Network and Kontera aren't being able to make significant inroads to AdSense / AdWords customer based primarily due to relevance, perceived or otherwise. However recently I am starting to see completely irrelevant ads as far as contextuality. The problem is deeper than simple not having relevant ads or even CPC ads. I suspect the problem is in the algorithm.
