I use the description tag on all my sites, they show up perfectly in Google.
However for some reason NONE of my or any wordpress blogs I have checked which use the plugin show the description, ever.
I know it looks right in the source but SOMETHING is wrong and it isnt with google.
Goto http://developers.evrsoft.com/seotool/ and put this url in as an example http://courtneytuttle.com/2008/07/03/the-three-keys-to-serious-freelance-writing-income/
It will say 'description meta tag' is missing.
Then put in an url of a normal html page, say this - http://www.techemail.com - It will show the description tag fine
I dont know what it is, you're right the tag is in the right place but Google and that tool doesnt seem to recognisize it for some reason yet it does for all my other sites and any other non wordpress site i check that uses the tag.
