My site needs to grow a lot

Hello everybody.
It's been six months since my last post here.
In all this time I have been trying to figure out how to increase visits to my site https://iohacker.com, unfortunately still without success.

On the site I search and describe the most interesting tech gadgets I find. There are often 100% original content posts.
My goal is to create something similar to Werd, Uncrate, Gear Patrol but more oriented to the Geek world.

Let's clarify one thing, I do all this first of all for passion. But the few visits do not gratify me.
Those interested in the subject find it pleasant and return to visit it with pleasure.

I think the main problem is SEO side. I also contacted a specialist on Fiverr but he did not find any particular problems. It has been online for almost two years now and I persistently write a post every day.
What do you think is the problem?
Do you have any advice to help me grow it?
Thank you.
