How are sites like this generated?

I was doing manual KW research and I stumbled on a domain that appeared everywhere for relevant keywords. When I clicked from Google SERPS, I was redirected to a page with a single adsense ad. However, when you type it in, the site is browseable.


Keyword page layout :
<h1>Main kw</h1>
Scraped content with hidden links
<h2>Related</h2>
[...more keywords...]
[ads]

Can you recommend a mass content generator that does a similar job?

Thanks.

remove the site! you don't need to out someone to give an example
