rewrite my article acording to this "splishsplash" guide

I have an article that I posted a year ago or so. It's ranking around 15 in serp and for an experiment, I would like to have the article rewritten following the guide posted by @splishsplash in this tread: https://www.blackhatworld.com/seo/guide-full-example-of-how-to-do-on-page-seo.1251425/
I would like to see if what SEO optimizing it will do to its SERP position

The article is about 2000 words and is a "best xxx " Amazon review article
