Welcome to the Q&A Forum

Setting up canonical tags for an old site. I really need advice on that darn backslash / at the end of the homepage URL.

We have incoming links to the homepage as http://www.mysite.com (without the backslash), and as http://www.mysite.com/ (with the backslash), and as http://www.mysite.com/index.html

I know that there should be 301 redirects to just one version, but I need to know more about the canonical tags...

Which should the canonical tag be???

(without the backslash)

or

(with the backslash)

Thanks for your help!

I believe that your choices will be restricted by the CMS that your particular e-commerce system uses. Does your e-commerce system provider have a user's forum where you can ask long-time users for recommendations?

I see you are not doing separate pages for sizes. I assume that you are handling that with a drop-down selector or something similar. How about doing that for the colors as well?

Otherwise make good use of the rel=canonical tag to avoid having lots of essentially duplicate content...
