Hey Guys, I am n00b here- was going through webmasterworld earlier and realized that the SERP changes (month by month) capture changes in SERP very effectively and helps us understand the changes behind SERP. Is there similar resource which I can use to understand cycles in adwords/adsense, relevance improvements, ux changes and comp metrics for google?
I'm not aware of similar lengthy threads, although someone a bit more involved on the Adwords/Adsense side might be able to point you somewhere useful.
I think that generally speaking Adsense and Adwords changes tend to have less of a pronounced impact on so many site owners, perhaps as a result of being less frequent, and also less severe in their effect. Whenever major changes happen they're widely discussed, but I believe they tend to be more one-off events than the ongoing algorithmic changes with Google serps.
