seo optimization of a cpa LP

While searching I noticed that one of my ogad LPs had received so much traffic and that Google had ranked it and brought me 2k/month of free traffic.
It's not at all optimizing SEO, do you have any advice, I was thinking about making a blog

niche: hack game

Since your page about hack games is getting a lot of visitors from Google without much SEO work, create a blog to keep attracting those visitors and improving your site's visibility.
