UrlCrazy is for the study of domainname typos / url hijacking.
It generates domainname typo permutations then tests them to learn if they are in use, estimates their popularity and more.
TYPES OF TYPOS SUPPORTED
Character Omission.
These typos are created by leaving out a letter of the domain name, one letter at a time. For example, www.goole.com and www.gogle.com
Adjacent Character Swap.
These typos are created by swapping the order of adjacent letters in the domain name. For example, www.googel.com and www.ogogle.com
Adjacent Character Replacement.
These typos are created by replacing each letter of the domain name with letters to the immediate left and right on the keyboard. For example, www.googke.com and www.goohle.com
Adjacent Character Insertion.
These typos are created by inserting letters to the immediate left and right on the keyboard of each letter. For example, www.googhle.com and www.goopgle.com
Missing Dot.
These typos are created by omitting a dot from the domainname. For example, wwwgoogle.com and www.googlecom
Strip Dashes.
These typos are created by omitting a dash from the domainname. For example, www.domain-name.com becomes www.domainname.com
Singular or Pluralise.
These typos are created by making a singular domain plural and vice versa. For example, www.google.com becomes www.googles.com and www.trademe.co.nz becomes www.trademes.co.nz
DOMAIN TESTS
Is the domain valid?
UrlCrazy has a database of valid top level and second level domains. This information has been compiled from wikipedia and domain registrars. We know whether a domain is valid by checking if it matches toplevel and second level domains. For example, www.trademe.co.bz is a valid domain in Belize which allows any second level domain registrations but www.trademe.xo.nz isn't because xo.nz isn't an allowed second level domain in New Zealand.
Popularity Estimate
We can estimate the relative popularity of a typo by measuring how often that typo has been made on webpages. Querying cuil.com for the number of search results for a typo gives us a indication of how popular a typo is.
The drawback of this approach is that you need to manually identify and omit legitimate domains such as googles.com
For example, consider the following typos for google.com.
| Quantity | Typo |
| 25424 | gogle.com |
| 24031 | googel.com |
| 22490 | gooogle.com |
| 19172 | googles.com |
| 19148 | goole.com |
| 18855 | googl.com |
| 17842 | ggoogle.com |
| 16490 | googe.com |
| 16367 | googgle.com |
| 15029 | google.cm |
| 14773 | gogole.com |
| 13227 | googlle.com |
| 11646 | googlee.com |
| 11345 | googlr.com |
| 7417 | foogle.com |
| 6132 | hoogle.com |
| 5313 | googlw.com |
| 5208 | giogle.com |
| 5151 | googke.com |
| 4838 | goigle.com |
| 4662 | ogogle.com |
| 4630 | gopgle.com |
| 4415 | goofle.com |
| 4118 | wwwgoogle.com |
| 3894 | goohle.com |
| 3399 | gooigle.com |
| 2675 | gfoogle.com |
| 1942 | googlecom.com |
| 1534 | gopogle.com |
| 1356 | googfle.com |
| 1089 | googhle.com |
| 892 | googlew.com |
| 747 | googlke.com |
| 618 | goiogle.com |
| 614 | goopgle.com |
| 413 | ghoogle.com |
| 341 | goolge.com |
| 232 | googler.com |
| 228 | gpogle.com |
IP Address
If the typo domainname is in use Urlcrazy displays the IP it resolves to. An IP repeating for multiple typos or IPs in a close range shows common ownership. For example, gogle.com, gogole.com and googel.com all resolve to 64.233.161.104 which is owned by Google.
