"Jagger" seems to be a mystery everywhere, including SEO Forums. Even webmasterworld is down hard. They chose to move hosting in the middle of this mess and crashed, till Monday according to their Site.
I don't think anyone knows: How to "Google" right now. This kind of alienation directed toward Site Owners, Entrepreneurs, Business Owners, Webmasters, Web Development Companies and SEO/SEM Companies can't bode well in the future, especially in primary seasons. They made the same timing error last year and didn't change their ways this year.
The recent earnings revelations revealing 7x profit in same quarter over last year looks like substantiation for Adword weighting schemes in the algs. Whether any monopolistic claims can be substantiated, is another story.
Whether it needs to be legally substantiated, is another story yet. Is there a gap between "Relevancy" and GOOGLE PPC?, If so, then user popularity will migrate elsewhere.
So far this update (Jagger) seems to have very little deducible logic behind it. IMO – That is a major marketing error on their part!
Companies, and livelihoods are at stake and they seem to be more and more tarnished by corporate earnings to some, especially the many Sites that fell completely out of the SERPs for no apparent reason.
IMO - Communication from GOOGLE to the public is becoming increasingly poor, which will inevitably breed more contempt by users at many levels.
IMO - It would be a serious Marketing Error to not act, and turn this one around now!
It's past time for GOOGLE to improve public communication.
You are laging way behind there, Google. Public Relations is the key to your future and that subset doesn't only consist of paying "Advertisers".
