Google plans ranking algorithm change to penalize doorway pages
Doorway pages are used to help rank a website for a particular keyword or phrase that is not heavily mentioned on the site itself. These pages are specifically crafted for search results and are not usually linked to anywhere on the site itself.
It’s easy to confuse doorway pages with landing pages, but they’re not the same thing. A landing page provides useful information for the user who visited whereas a doorway page simply tricks the user into coming to the site by showing irrelevant information in search results.
Although the technique was already considered spammy by some search engines, Google said today that it plans to tweak the algorithm further to penalize those pages in results:
Over time, we’ve seen sites try to maximize their “search footprint” without adding clear, unique value. These doorway campaigns manifest themselves as pages on a site, as a number of domains, or a combination thereof. To improve the quality of search results for our users, we’ll soon launch a ranking adjustment to better address these types of pages. Sites with large and well-established doorway campaigns might see a broad impact from this change.
Google has also clarified its definition of a doorway page along with adding questions to help you understand if what you’re using is a categorized as one.
