I always go into Dreamweaver and place this code on my index page after I upload my website from "Designer Pro 6"
This is the code.
<meta name="robots" content="index,follow">
<meta name="revisit-after" content="14 days">
<meta name="googlebot" content="index,follow">
<meta name="msnbot" content="index,follow">

I was wondering if I needed to have this on every page of my website in order for them to be included in the search engines?

Also, is there a way to place this code into my pages as a place holder, so that I don't have to do this step after updates to my websites?
