Welcome to the Q&A Forum

It has now been switched back...

The key word is "medigap insurance" the sub-page was not optimized at all (I just fixed it up today, the page did not have a single link pointing towards it and the article on the page didn't explain much). My site is www.mostmedicare.com

A sub page now ranks for my main key word (the file name is exact match to the key word) it completely replaced my index page in rankings.

Would 301 redirecting the sub-page to my index page (which is more informative and has a whole lot more links pointing towards it) be a good idea or vice versa? Or would optimizing that page (the sub page) be the best way to go (the sub page doesn't have single inbound link pointing to...).  This happened about a week ago.

Thanks!
