suggestions on improving my sites seo

Hey, would like your feedback on how to improve my websites SEO.
I've included meta, open graph tags.
I have a robots.txt and site map files.
What else can I do to improve?
How do I get started with back linking? I put my website to be indexed on Google search console but a few days have passed and there's nothing.

Also if you have any tips regarding ads... I don't want to put too many.

Paste the URL of your site in Semrush and it will tell you everything that needs to be fixed in your website.
