Hi all. Referring to Wordpress 3.x, what is the function of 'post tags'. How do they work, and should I add them to future posts I make on my blog? Thanks, ~ Andy
Tags allow you to assign certain "key words" to your posts. Below a post, you can choose to display those tags which will then link to a page on which all posts with said tag are listed. You can also use it to display related posts. Hope that helps.
To expand on this a little bit, tags are good from an SEO (search engine optimization). Although not as useful as they once were, they still help with seo because you can assign keywords related to the post which helps your on page seo (kw density), and also because it will link to that tag page with that anchor text. I hope that's not confusing!
