In these 2 weeks I was using Flarum on my website, the design and upload speed were very good but on the SEO side they are very neglected programmers since it generates too much duplicate content one of Flarum's problems in SEO:
All question pages have the same meta description as if the same keyword competes with each other.
You do not have meta keywords.
It does not have friendly URLs that Google considers it in the web positioning.
It does not have short description, which would serve to use it in the meta description.
The tags and categories do not have a static page.
and many other things but the little time that I was here was great, but unfortunately I will have to stop using Flarum and I will choose to use another CMS that will not be messed up here, for the content and advertising policy.
Thanks Flarum
