Typo-Squatting
Typo-squatting is the practice of registering a domain name that closely matches an existing (popular) domain name in the hope that it will receive visitors who misspell the original domain name. Using the word “mortgage” for our example, typo-squatters may register domain names based on a common misspelling such as “morgage.TLD” (which is missing a “t”), or they may register the correct spelling except for a single character that is often typed wrong such as “nortgage.TLD”. You’d be surprised how many people miss the letter “m” on their keyboard and hit the “n”, and for a popular existing domain name, a typo-squatter can gain a lot of web traffic from these types of user errors.
