I read pretty recently that Google was temporarily dropping the rank of pages that had their title tag changed. Is that still happening
Whenever I want to do that, then if it's a site that doesn't get much updating normally I usually make a small change to the on-page text to try and give some back-up to the Tag change. If it's a regularly updated site, then I don't always do the back-up change.
