How to get free visitors to my page when it's not dealing with search terms being frequently entered?

I want to get more visitors to my blog posts, which are not optimized for searches - I write about stories of interest that are not directly searched for.

Now, if I write it on some social media platform, I have several drawbacks

1. I don't get revenue, but the owner of the platform gets ad revenue for my posts and free seo.
2. The owner can restrict access to my posts, edit them.

Obviously I tried writing my blog post in some forum up to a cliffhanger to add a "see more at <blog post url>", which made me get banned.

And by just writing about it and putting it into google, nobody comes, because, as I wrote, nobody searches for it.
