I did an analysis on my 2 sites that were ranking top 2 positions for the same niche. Site A was ranking position 1 with stronger links from from a service provider here in BHW. It had higher percentages of exact match anchor text. After May 15 Site dropped to position 7. Site B had the same strong links but less than site A and had more diversified keywords with the exact anchor text same percentage as other LSI keywords and generic terms. Site B wasn't affected much. It's still in position 2 for target keywords. I am beginning to analyze that this update might have targeted sites that had higher rate of exact anchor text. So I will wait till sunday if I don't see ranking settling down I might remove some links and put more naked URL's and not focus on exact anchor texts. Will report back next week. I might get some feedback from people who might have been affected by this weeks minor/major update.
