How to promote a new site?

Question

Search engines

Hello.
There is a small website that is less than a month old - digital paintings to order (not action processing, but I draw with my hands on a tablet).
Inside the site tags, description, title, opengraph, json-ld made. I'm preparing the text.
Can anyone tell me in what direction to move on in order to create a reliable base for the site for the growth of visitors?
Because most of the cases found on the net are based on "made a landing page and direct" - and I think that this is a road to nowhere
Thank you all.

Answer 1

and I think it's a road to nowhere

Why reject one of the most profitable and simple options? Or lots of clients?
SEO and direct do not interfere with each other. They need to be combined.
