Hi all,

Last week submitted a site map to Yahoo! in the hope that they would start to

index more of my pages.

I've been watching it closely with y! Site Explorer but in the last 2 days the

number of my indexed pages had dropped from 455 to 20!!!

Any idea's why indexed pages have fallen out?

This happens with Google and MSN, too. They are constantly in flux as they update their indices and their algorithms. It will return to normal soon unless you have been doing something that warranted this (and only you know if you have).
