Build a bot to crawl the deep-web jumping from directory to directoy via a white-list of your keywords, scrape and post (as it has never been indexed lets call it post not re-post) to your money-site which is super easy on wordpress using the API. You could monetize with skim links or similar or create your own plugin with a find replace on CTA's / keywords, shit you could fully automated a unique content tier 1 mega pbn in no time with this.
Tier 2 via fcs or ranker x, ranker x you will need to build some kind of ubot to populate your scraped content but it works in theory, if fcs be sure to integrate api to GSA SER and go contextual, content here is less of a problem, shit you could go article builder (400 articles a day woop woop) or Kontent machine and really drip feed these contextual, tier them up. Personally I would go 1 project per keyword and I include raw / generics as keywords for diversity.
It may take a couple of weeks to set up but, you have not paid for content other than article builder kontent machine and you should end up with an enormous unique killer pbn.
I forgot the question.
You are welcome.
