Rel Canonicals not working properly.

[jmigdal]

We recently implemented rel=canonicals on a few of our pages to prevent query parameters from showing up in the SERPs. The two pages we added the tags to are no longer ranking. The pages used to rank very well for branded terms such as "morningstar direct" and "morningstar sustainability", but now don't show up at all. When you search for the urls specifically, for example "products/direct morningstar" the query parameter is still indexing.  Does anyone know why this might be or what we can do to fix this issue?

The two pages are www.morningstar.com/products/direct and https://www.morningstar.com/company/sustainability

Hi there!

The canonical tags in those pages are implemented incorrectly.
There should have absolute urls, like: https://www.domain.com/page/product/

So, the canonical here: https://www.morningstar.com/company/sustainability
should be:

Look, there are 2 changes from the current tag:
1. https:// at the beginning
2. Removing the trailing slash at the end.

In both pages, the changes are the same.

Best luck.
