“Type-in traffic” describes visitors landing arriving at a particular web site by entering a word or phrases in their web browsers navigation bar just adding .com or increasingly a co.uk (any top level extension).

This is rather than following a hyperlink from another website or for example by searching for a link using a search engine.

Domainers register domains based on popular generic terms (and sometimes trademarked and copyrighted terms) in order to earn income from “type in traffic.”

Quite often the target website will have a lot of PPC (pay per click) links from advertises targetted towards the domain name, and the domainer will get paid if the visitor clicks through on any of the links.

.com domains have been the most popular domains to use for this because until recently if a visitor omitted the domain extension in the navigation bar, most browsers would automatically add this gTLD.
