url structure problem

how can I migrate smoothly?

[itisgene]

On my web site, I created www.mysite.com/keyword1_keyword2/products1_products2.asp

I want to change it to

www.mysite.com/keyword1-keyword2/products1-products2.asp.

The first one is already in the SERP. but I want to change the url structure to hyphen(-) based one for consistency.

My other pages are all "-" based.

I wanted to test underscore(_) but it seemed not working that well.

The question is how can i make sure the google list this hyphen based urls instead of underscore based urls.

I already changed all the internal links and menus to point to the new urls. I also redirected all the traffic from the underscore urls to hyphen urls.

Is there anything I can do to speed up the correction in the SERP?

Thanks!

Make sure the redirects are "301 Moved Permanently" otherwise you'll have problems.

I always add <meta name="robots" content="noindex,follow"> to all pages I want SEs to drop.
