Typosquatting is a term you may have seen when reading about Internet scams. In essence it relies on users making typing errors (typos) when entering a site or domain name. Sometimes it is also referred to as URL hijacking or domain mimicry, but IMHO the word typosquatting describes the matter more adequate.
Roads to success
As you will understand the success of a typosquat scammer depends on the number of victims that are likely to misspell the intended domain and land on the scammers’ pages. To maximize the success rate takes some insight into the workings of human mind-fingers coordination.
Another thing to keep in mind is that there are many different keyboard layouts, so replacing one letter with an adjourning character on the QWERTY keyboard does not work for everyone.
One road to success depends on the occurrence of double letters in a domain name. A regular mistake is to type the consecutive letter double instead of the intended one. For example the rather famous goggle[dot]com.
Another often used trick is to try and register domains with the same name but with a different top-level domain (TLD)
