steps to take, one by one

I hope this works, if it doesn't, if you click on the white search box at the top of the page and start typing SEO search list, one comes up.. I don't know if it is what you want or not though. Site Checklist For SEO

I too believe there is more than good keywords.. the offline seo is what I think you may be missing... also, I feel more inclined to Yoast as well

Something I did on 2/9/2016 helped but didn't get me out of the woods with the search engines. The nosedive that my SEO recently took was frightening. A shift in my direction took place with Yahoo, but Bing is still refusing to list my site even when someone types in the exact site title or the exact domain address. They won't even list my site on page 10. This is what I mean when I say I'm getting blacklisted by the search engines.
I'm still trying to figure out the right formula for putting affiliate links on product pages and not getting punished by the search engines for having too many affiliate links or placing them where the search engines don't want them.
