Help is needed. How to attract visitors to the site?

I ask the help of habrovchan in the promotion of the site. I tried to do this myself and I will try further, but the results are zero. I feel like a boob, unpleasant. Can someone really help with practical advice? How to attract visitors to the site?

I have already read about optimization of the site content (Ashmanov, “Website promotion in search engines”) and optimized it as I could.

I would like less general advice, and more specific. I ask no one to do the work for me, but I just want to know where to go though.

Thanks in advance.
