echo "
<META name=\"description\" content=\"".$_GET['description']."\">";
with the url being something like this:
[yoursite.com?description=homepage...]
PS: Thanks, again! :)
"Apache: has a special rewrite module that allows you to translate URL's containing query strings into URL addresses that search engine spiders can follow. The module, mod_rewrite, isn't automatically installed with Apache software. Check with your Web host or administrator and see if it's available on your server."

[edit reason] url removed [/edit]
using query strings is still not the best thing in regards to search engines. Stay away from them all together if you can but if necessary use mod_rewrite to make urls look static.
