The "SEO Is Dead" niche is quite active these days, also very easy to get into. What you do is give yourself a good title on a forum, a title which says "this kid knows his shit". You then write a forum post, but you tell people the forum post is too long, and if they want to read the full article, they are best of reading it at your shit blog. Then you write and article on your blog about SEO being dead, at the same time your blog is full of affiliate links for GSA and SB, dumb kids get confused and start buying SEO tools even though you are telling them it is dead.
