I own a website that has gotten about 300 referals a day from MSN that has about 4000 pages. As of 3 days ago the traffic went to 0. About half the pages are being indexed to. I am trying to figure out if this is an ALGO problem or an MSN indexing issue. Any thoughts? or similar problems? We don't even rank for our own TITLE which is unique and we should rank 1. I have some other websites that we do the same types of SEO to and they all are in great position still.\ We are an electronics retailer...
MSN has been known to do this, even though your site appears to be indexed still. Usually after a couple of days/weeks you should see a return in rankings/traffic.
My experience with MSN, if your site suddenly disappear from MSN search don't worry it should be back and rank again in 2-4 weeks.
