SEO is mostly ignored by search algorithms anymore, keyword stuffing is long gone, back link ranking has diminished values, even link farm sites don't work like they used to.
With the advent of high density a.i. algorithms operated by the site aggrigators like search engines, the only real thing that will give your search ranks any muster will be understandable common-phrase content tuned to the subject. Ai will be looking for that to give your page relevance to search users.
I think focusing on relevent content will benefit being found in searches, and hopefully convert some traffic. And maybe some word of mouth or back links will organically happen.
But I hate manually spamming websites.
