You want to invite everybody to your website, but it's such a pain writing up all those invitations. Save yourself from writer's cramp and put a meta tag on your website. With the inclusion of a completely invisible meta tag, you can control how your site is categorized. Don't make search engines guess what your site is all about: Tell them.

This is how meta tags work: Most search engines create their databases of Web content using automated programs that constantly traverse the Web, indexing every single page. If a website has a meta tag, the search engine's program will get a site description and keywords from the meta tag instead of trying to determine them from the site's content. They're especially good for webmasters who have initial splash pages with minimal textual content, or for sites where all the content is locked in frames-- many search engines don't index frames' contents.
