The latest post on SearchEngineLand, by Vanessa Fox, gives confirmation from Google that MayDay was indeed intended to whack 'long tail' sites which have lots of single-serving landing pages.
(can we post links to blog posts? sorry Im new..)
It whacked me big time - google searches down from 1400/day to 350/day, enough to kill the business.
And my users think my site is better quality due to the 'instant gratification' they get from finding things quickly, without needing to click from some densely-packed parent page.
This is so upsetting - I would much rather be building my site than constantly dealing with the latest google change.
Better yet, get the sites who are impacted financially to join together and hold google accountable for their secretive judgements which destroy livelihoods - contact the guys mentioned in this NY Times article [nytimes.com...]
Excuse me, Im just blowing off steam at the moment. I do have lots of data to share and thoughts on how to proceed.
