Hi,
I am confused that those URLs are required to have feed items stored in my database.
I also run https://vrsquare.co/ and that site uses the exact same feed sources. And here I don’t find a similar /feed-item/ folder, just the feed itself on the homepage.
I feared that the SEO ranking would be impacted negatively, because as far as I have understood, the SERP-algorithms value pages with lots of quality content. A site with many “almost” empty pages might dilute the overall impression of the domain.
Anyway, I managed to set the noindex flag on the feed item URLs, so that would no longer be an issue. Thanks for your answer.
