Can you provide at least one example of a clear change of the Google algorithm? It is something you can't be exact with. Meanwhile - here is a list of the Google algorithm changes that are broad in nature...
SEO_Watchdog - very nice article. Seems like everything I read is about working backwards to deal with what Google has done in the past. Nice to see an article that looks forward - and how to get ready for forecasted changes with Google's algorithms. Thanks!
I don't know a bunch of my established sites lost major SERP rankings on competitive keywords. Anyone else get this?
No one but Google knows that. How would any of us know? If g makes a major change and if they announce it, it is usually through Matt Cutts. So watch his blog for any mention of algo updates. Then you will know as oon as the rest of us know, maybe sooner. /*tom*/
c'mon lads try and keep up, this isnt difficult, they update constantly, and the last major one was called Vince. there have been a few more changes of late, outlined here April Algo updates
They dont share the secrets of algo at all, Updates if any are not necessarily communicated everytime
