Yes, i'm interested in SEO, for this reason i'm trying to modify the .htaccess file in the right way (but, unfortunately, my knowledge on this is not enough...).
What kind of structure should i use to be sure that a search engine will index my new pages? (they are in the same domain)

RewriteRule ^contacts.html$ [mysite...]
RewriteRule ^about_us.html$ [mysite...]
##do this for each HTML pages to redirect them permanently?
....
....

or it is better a syntax like this...:

Redirect 301 /about_us.html [mysite...]
...
I hope to get because i need a solution from you!
