Great post by Matt Cutts of Google named SEO Mistakes: sneaky JavaScript warns SEO’s and webmasters in general of using javascript redirects in doorway / spam pages.

This time he gives a great example of a site which created dozens of auto generated content pages that not only make no sense, but even redirects to the homepage using javascript.

He sums it up and says:

So let’s recap the high-risk techniques that I would recommend avoiding:

• Don’t use programs that automatically generate doorway pages.
• It especially looks bad if the doorway pages are gibberish.
• It really especially looks bad if the content you use is scraped content.
• If you’re considering scraping content, doing it in the SEO industries is one of the worst places to do it.
• If you scrape SEO content and end up scraping a couple spam pages, you may
  get noticed even more because someone is investigating the other spam pages.

and then:

• If you make lots of pages, don’t put JavaScript redirects on all of them.
• If
  you’re doing JavaScript redirects, don’t obfuscate the code–it just
  makes people think that you’re doing things after lots of deliberate
  consideration.
• If you do obfuscate code, ask yourself: can a
  regular person still look at this code and tell what it’s doing without
  even knowing JavaScript?
