Does Google use the Meta Description Tag for Description of Page?
I've got a simple website that uses a php script to geolocate a user's IP and redirect accordingly - UK users get sent to the .co.uk html site, while everyone else gets sent to the .com.
Whenever the site shows up in google, however, the description is completely blank. I've tried adding tags to the html, and also via echo in the php, but still nothing shows up. The site's been up for a few months, so it's been well crawled and scores pretty highly for some search terms.
Any ideas how i can get a description up on the SERPs? Thanks!
