After 24 hours, my observations:-
- losses on some keywords - losing 2 to 3 positions on first page, yet traffic UP about 10-15% across a lot of my sites - likely wins on longer tail keywords (haven't confirmed yet). No clients complaining at all yesterday.
- domain clustering not fixed yet
- an SEO company I know that got TOTALLY obsessive with cleaning up their backlink profiles got hit pretty badly by Penguin 2.0. This is a company that I know well - speak to on the phone regularly. They tell me they disavow and also have spent a LOT of efforts cleaning up their backlink profiles. Anyway, I was always interested to see how they'd do with Penguin 2.0 - on 3 sites they actually run themselves (not their client sites), all lost 4 to 6 positions on many keywords - meaning heavy demotion on first page, or relegation to second page.
- one site that sold links up front and centre on their home page and also had a spammy backlink profile got hit by Penguin 2.0 (and survived Penguin 1.0 somehow) - a great example of Penguin 2.0 hitting a target square on and killing it - Google do get it right sometimes. This site occupied no.1 spot on a popular 1 keyword phrase. Not inside the top 100 now.
OVERALL: no real damage done, some gains made.
