If you have read my previous post about meta tags, now you may want to have unique description and keywords for your pages (well, unless my previous is not well stated, which could happen though).

Adding meta tags to your categories in php link directory is easy. You do not need any additional mods to achieve that. I am using the phpld 3.1 version. So I am sure 3.2 have this feature as well.  To add meta description and keywords to your page, log into your admin panel first. On the left side, click categories. Then you will be able to see a list of categories on your site including the top level one and sub categories. Scroll to the right side, click on edit (a icon with pencil, very descriptive), Then you will see the meta tags section, simply put your description and keywords. Voila, now you are heading towards good SEO practices.

I also strongly suggest you to fill in the description for the category. If you do not have time, ask your girl/boy friend to do it. It will be a good chance to see whether he or she really likes you or not.
