I have 17 unique posts, next natural step?

Thanks guys for the awesome answers! Just found my post again and now at 30 posts. Im focusing heavily on content atm, also trying to get links disavowed lol.

Considering its a food blog, pinterest and guest blogging and commenting on authority food blogs sounds really promising.
Does the commenting and guest blogging go like this:
- commenting: you find a recipe that you also have or relates to you and comment something good and put an anchor text to the comment?
- guest blogging: write a recipe i have on my site and share it by guest blogging and also add the link back to my website?

I might use pinterest and YT by just adding my recipes there with a link and hoping to get some traffic. You think this would work?

Social media is also one of the best choice to get more traffic to your site...you can create a page for your site... but try to get natural likes for that page ,only natural like will last for long time...also you can create a video about your site post it in YouTube....
