@jbob Just to clarify this briefly…
If you’re only referring to the blog post listing page of the blog collection, then Ben’s suggested approach should be the right one.
But if, as I suspect (and what would make more sense), you’re actually talking about the individual blog posts themselves, then this is currently not possible using Elements’ CMS blogging in the way you intended.
The reason is that, for individual blog posts, the canonical tag is always set to the main blog listing page. As a result, the individual posts are not being indexed by search engines.
I already raised this issue with Ben in the past, and hopefully it will be added to the to-do list soon.
