It seems that it isn’t just Google where there’s a problem when www and non-www are both accessed separately in a browser, but that it may just be necessary for Yahoo as well.
I just had a site that’s had the same rankings at Yahoo for a LONG time for the homepage lose those rankings altogether at Yahoo, with the homepage dropping way down doing a site: search.
I thought I had non-www redirected to www. on all sites, but the host had moved servers and I can only guess that there was a glitch, that I’d gotten by without it all along, or that there had been a change at Yahoo.
Bottom line: I put mod_rewrite redirection so that it redirects to www. and in no time it’s back ranking exactly where it was, with the homepage showing first when doing a site: search and Yahoo traffic restored to normal for those search terms.
