Best BlackHatSeo tactics for my website

I have a college guide website but it doesn't get much traffic. Most traffic comes from my social media and Facebook ads. Any advice or tips on the best way to boost college targeted traffic. Also I monetize it with Amazon affiliate links so it helps when visitors click link in my guides

Blackhat - do private blog network or buy PBN links in the niche.

Else add nofollow rel on the affiliate links - even noindex. Or better cloack them somehow.
