The problem is the following: the SPA has only one index page instructing the browser to load a Javascript bundle that will serve dynamic content (typical Angular application). The content served is different depending on the URL to request it, but to the indexing robot all pages look identical, although what the user sees is very different through the javascript interpretation.
e.g.
https://one.linkfacts.link/us/hubert_schumacher/g/FalaciesOfMind/n/PoisoningTheWell
would be different from
https://one.linkfacts.link/us/hubert_schumacher/g/FalaciesOfMind/n/Overgenerality
but look the same to google from a pure HTML perspective.
How can I "force" google to index the different pages by their accessed URL? Would it be enough to put the URL or any other differentiator as a meta tag (e.g. Description) into the header?
Any other solution, one could think of?
