I know that everybody sets up their sites to be Google-friendly, but don't forget MSN. It figures very promiently in the search engine wars: it's responsible for 36.5% (according to Search Engine Watch, July 2005) to 52% (WebSideStory, June 2005) of all searches.
You can find info for site owners here . An interesting tip for those who have written off meta tags:
Add a website description into a Description meta tag, as shown here:
<META NAME="Description" CONTENT="Describe your website here" />
See [URL=http://search.msn.com/docs/siteowner.aspx?t=SEARCH_WEBMASTER_REF_RestrictAccessToSite.htm#C]here[/URL] also.
