If you answered, "How the heck should I know?!", you're not alone. But I'm going to show you how to check.
Bottom line, if you're website isn't verified with Google, you're certainly not getting the "Google juice" (better known as SEO results) that you should.
So here's what you do:
1.) First of all, sign in or sign up for a Google account on Google.com...it’s free.
2.) Then, go to your settings where you’ll find Webmaster Tools.
3.) Click on Webmaster Tools and you should see two blue bars...one that says “Messages” and one that says “Sites”. If your site is not listed, click the button that says, “Add a Site”.
4.) After entering the URL (complete with the http://), you will be given a code. Enter that code on the home page of your website and you’re all set!
It’s not a lot of effort and it will help improve your SEO results. After all, Google doesn’t have to search for you anymore...you sent Google a message telling them exactly where you are using that code :-)

Thanks for the reminder. I have added several sites since I was last in my google account. Time for an update!
I did the same thing which is why I sent out the reminder :-)
I need to fo look and see which sites I've done... I'm sure that I have missed one or two...
Thanks for the information. I have to believe the guy that built our site would have known to do that but I will check.
Tara - Thanks for pointing out this Google feature. It appears to be very valuable.
Tara, I will check it out. Thanks!
Ok, I have been trying to get my site verified now for an hour.... still working on it. Think this is a good idea-- but problems implementing it... kathy
