Repurposing affiliate site

I’m redoing existing pages and adding new content and tags for an aged affiliate site.

Turning it into an article/review themed site along the same interests.

Is there anything I can do to encourage Google/Yahoo/Msn to reprofile the site?

Would it help to include new site maps in htaccess?

Site map is very important i advice you to use it

Would asking Google to reconsider the site help?

webmaster tools > “Help With” > Site Reconsideration

Site Reconsiderations are normally only used when the site/page is banned/removed altogether from the rankings.

If you are merely repurposing/replacing the site and/or it’s content then your request will almost certainly be ignored.
