Site assets index page showing on search engines by default

For a large majority of our site assets, their homepages, which usually sit at /home, seem to take precedence over the root url of the site asset on Search Engines - eg. Google

For example https://www.ulster.ac.uk/home is shown by google, and https://www.ulster.ac.uk is not shown.

Does anyone else have this issue and what is the best solution?

We tried to use canonical urls but Search Engines are not honouring them.

Are there any links to /home? First look at removing them and make them just go to the root domain. Your google analytics should be able to tell you that.

Other alternative is to redirect from /home to the root domain with a 301 redirect.
