Do Query Strings strip away SEO value?

[Marketing_Today]

Hopefully a yes or no answer to this one...

If I have a link pointing to my site as below, is the SEO value stripped away because of the query in the URL?

The above mentioned page also has the canonical tag:  on it.

Hi,

At least not in above case. As you mentioned that you also have rel canonical tag that means you don't want to index query string URL.

Thanks
