I'll create an authority site.
That fails because it requires a lot of upfront work, you have to actually create real content that people/traffic will want. Odds are their idea of authority is based on page volume, If they have a bunch of pages it must be an authority.
I'll create a network of MFA sites.
That fails because they soon figure out the sites are weak/thin & can't even support themselves when trying rank a page. No traffic equals no money.
I'll create an auto blog.
That ends up failing once they figure out they don't have a clue what they're doing. Google eventually buries the pile of dung site in Supplemental SERPs If they're lucky enough to even keep the site indexed in Google SERPs.
I give up, I'll go try another IM sub-niche.
If they're honest, they never really tried anything, just a bunch of useless time wasting gimmicks they found in outdated ebooks.
The cycle repeats, only in a different IM sub-niche.
