I wasn't really a power-user on those sites but if the content was good enough it usually got a decent amount of visitors from these platforms and then sometimes these visitors wrote about it on their own blogs (and then it generated backlinks for SEO) and the cycle continued.
Nowadays it seems to me like you can't get traffic without buying it through ads. I started writing some posts again which I believe deserve some traffic (shameless plug - textcritics.com) but I can't figure out how to start the ball rolling.
On Facebook, Instagram and Twitter you have to have tons of followers or friends to get some attention (which I don't and I would also like to stay anonymous so these platforms are out of the question) and on Reddit and the likes (and Hacker News...) you have to be a power-user or the community trashes you.
There are no ads on my website, so I'm not making money out of it, it's just a hobby. But even if it's a hobby, I still want people to see my content :)
Any ideas (other than writing this)?
The major point is just to be honest and authentic with your audience. Look at it as a conversation with people, not just as a platform for you to push content at them.
I recently used it and I'm starting to see results.
The major issue it takes time. Hope I helped.
