last month 2 sites dropped off the index.. they can still be found in yahoo and 1 page in msn.. but thats it. they have no page rank.. where they used to have page rank 5
so is it worth renewing ot just let them expire? thank
No, page rank [webmasterworld.com] is a method that Google uses to score pages and has nothing to do with Yahoo. You did say your sites are ranking in Y! and msn right?
I rarely will let a domain expire, you never know when its going to come back from the dead.
