Welcome to the Q&A Forum

Thanks Guillaume,

I'll give it a try with GWT and Bing Webmaster Center.

Cheers,

Thanks Keri.

Yes, it's actually an "Add This" bookmark button provided by them. I'll have a look to the settings options. Thanks again

Hi there,

When searching site:mysite.com my keyword

I found the "same page" twice in the SERP's. The URL's look like this:

Page 1: www.example.com/category/productpage.htm

Page 2: www.example.com/category/productpage.htm**?ss=facebook**

The ?ss=facebook is caused by a bookmark button inserted in some of our product pages. My question is... will the canonical tag do to solve this?

Thanks!
