Traffic booster sites differ from other sites which are designed to act as a doorway page or a simple lead generation site. Each traffic booster site is a stand-alone site with unique content designed to rank well in the major search engines.
Content Farms: Recently, Google has declared war against content farms. Content farm is defined as a site with shallow or syndicated content designed to bring in visitors for the purpose of having ads clicked. Pretty much most of Google Ad Sense sites fall into this category.
1) Google started to penalize these sites by lowering their rank. 2) Ad to content ratio is high per page. 3) Syndicated or overused content is prevalent on these sites.
Doorway Pages: Doorway pages are web pages that are created for spamdexing, meaning spamming the index of a search engine by inserting results for particular phrases with the purpose of sending visitors to a different page. Doorway pages are also known as portal pages, jump pages, gateway pages, entry pages and by other names. Doorway pages that redirect visitors without their knowledge use some form of cloaking.
1) Google does not like doorway pages as they add no value to the search engine users. 2) Doorway pages typically do not get ranked well. 3) Doorway pages do not contain any content since they are designed to redirect users to another site.
Lead Generation Site: Lead generation sites are created to capture visitor's e-mail for e-newsletter or sales leads. You can see many of these sites listed on the sponsored links section since these type of sites are hard to rank on the search engines organically.
1) Lead generation sites lack unique informational content because most of them are one page sites with a form in it. 2) Lead generation sites do not get ranked well organically.
