Of our 5 websites that run on the same platform with basically same promotion strategies, 2 completely lost all traffic about 1 month ago during the changes with SE crawlers that yahoo made and the index update happened about 1 week after we lost our rank. Our other 3 sites recieve a considerable boost in ranking. The 2 that lost all traffic also are having major indexing issues. That dropped from 9000 pages being indexed correctly to about 200 pages that are not getting read correctly (Titles not showing). Anyone else experience something like this or have a solution? Yahoo has not responded to me.
