Lets just say i’m a dirty affiliate and utilizing a Black Hat SEO technique called a doorway page – Serving Different Content to Different Browsers
As said Black Hat SEO i offer an affiliate link to every human that browses my site and when the User-Agent for this example we say..
Google – (Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) or (rarely used): Googlebot/2.1 (+http://www.google.com/bot.html)
or Bing – (msnbot-157-55-107-141.search.msn.com)
The page that is served is actually quite different from the one that the bot sees because maybe there is malware, cookie loading or other nefarious browser-matter that will cover the spectrum of 1000’s of affiliate networks that offer good CPA’s on signup.. that can be loaded into the browser and last for months.. How do i know this you ask? well.. i know how its done- thats all i can say.
But let’s use a different, more innocent way to serve different content to different users and use something like geographic co-location.. ooh thats a lovely word isn’t it? Geographic Co-location in example would be something like when a company is doing split testing of a website in a given area.. for whatever purpose .. they don’t tell the search engines that they are doing it and yet don’t seem to get penalized for it. Or Maybe, it because they are trying out different modules for different browser extensions. I like that one its more juicy.
So if i were to do these tests I’m sure as a developer i would set all of the browsers apart and instead of changing it for just the bots, i would change it for clusters of browsers. Firstly in sating that little Gem of Black Hat Genius (or just pointing out the obvious), i use these “Holes in the Seachsphere” to do the latter and i am certain that any “BlackHatter” would actually be too lazy to create thirty different versions of a website so for the most part we are still safe for now.
Im sure a bunch of you are wondering “You put 1000 affiliate links into 1 webpage?”
The short answer is yes, and the how is not readily shared to anyone.
What i will state is that:
Yes – Serving different content to search engines than you do to human visitors will get you banned – If your Lazy and don’t segregate your content into more than just 2 or 3 groups.
