Website – automatically generated site under a pre-defined keyword. The website is generated with the help of special programs.
But what the doorway creators make these sites? Let's face it. Imagine some online store to sell some goods, such as a new kind of TV. For this he needed a large number of interested visitors who will come to this site (traffic). To attract them, you can use contextual advertising, but if the shop is going to sell a lot of goods, ordinary advertising is not enough. This heavy traffic can provide doorway pages. Therefore, this online store buys traffic from doorway doorway creators.
I said that the website is generated under a specific keyword (in this case TV). Because the site is generated, the texts written in human language it is not present, and there are just a meaningless set of words that contains the intervals is the key word. This is necessary in order to doorway have reached high positions in search engines and more people for this keyword came to a doorway. Is it called black optimization. When people type into a search engine the word "TV" with a high probability they go to a web site with that keyword, which automatically redirects the visitor to the site, and bought doorway traffic (in our case a shop). Now search engines have become faster to compute doorways automatic redirection and doorway creators come up with more sophisticated methods.
In principle, it seems that the scheme is interesting and you can earn on the websites, but there are many drawbacks. First, standard methods of promotion of sites to the doorway not applicable, because, for example, no self-respecting advertising service will not undertake to advertise this kind of website. Secondly, a lot of doorways cannot be placed on a normal hosting (simply not be allowed, because the site is generated), you need to look special. Thirdly, doorways often are banned because of what you have to constantly create new doorways. Ie, you cannot stop, if you are hunting to obtain a decent income, you need to create a bunch of doorway pages, and it constantly takes time and thereby clog the Internet.
In principle, if creating a doorway wondering you can try. For this you need a program — doorways (doorway generator), hosting, domains for the websites and affiliate programs that you will be promoting.
But not everyone will be able to obtain a great income in a matter of days, which is discussed in the Internet. Do not fall for the bait.
In my opinion, if you value your personal time and you have the knowledge and skills that can be useful to people, it is better to create a full website for people and earn on it.
