There has been a lot of talks about meta tags lately, most webmasters wondering if they should still stuff them with key words or just drop them altogether.
The truth is that what matters the most these days is your title tag as well as your page content, meta tags not really being part of the equation anymore — at least for major spiders such as Google’s. The only tag that might still need your attention is the description, which sometimes shows up as a snippet in search results.
However, if you still have meta tags on your pages, there is no need to get rid of them: they certainly won’t hurt and might even still be used by some minor search engines.
