Landing Page – a page designed to ‘land’ a sale. These pages typically read like direct-mail sales letters – lots of customer testimonials and guarantees about how great the product is and ‘hurry, this is a limited-time offer!’ copy. This is not auto-generated spam, it’s carefully written by a marketing copywriter.

Doorway Page – (aka Gateway Page) a page that is intended to be found in searches for a certain phrase, and then redirects the visitor to another page or site. This is a spam tactic involving the setup of several pages, possibly on several different domains, all acting as many different ‘doors’ into the same page/site. Frequently used cloaking scripts to present different content to the search engines than to visitors, prior to modern search engines’ ability to detect cloaking.

MFA Page – (Made For Advertising) a page that carries no valuable or original content, existing only to serve ads targeted at a specific search phrase. Use autogenerated content and/or automatically scraped chunks of content from other sites in order to appear relevant to a specific phrase or list of phrases. This is spam.
