Sigh. Another one who's been brainwashed by Google. Content doesn't matter. Backlinks do. Check the biggest money keywords in your niche. Churn and burn is the way to make money now. If you want to load your website with lots of pretty content then go ahead. Waste of time.

If you have 50 articles and make 300 web20s do you just reuse each 6 times? And use unique titles for each?
Do you build any other backlinks or only web20s? Did the sites have any other backlinks before you started?
And thank you for sharing
Just setup a new website, going to implement everything suggested by OP to find out if this actually works once and for all.
