what is a typo for spiralfrog???
Typos are mistyped character strings (sequences) that are resulted from ... TYPING.
1. A, S, D, F, as well as J, K, L (and ";") are less likely to be mistyped, because they are where your fingers rest; even more so with D, F and J, K because your index and middle fingers are more sensitive than the other 2.
2. So the usual typos are coming from those letters on the upper and lower rows. Take SPIRALFROG as an example, P, I, R are easier victims. HOWEVER ...
3. When people mistype, they will SEE it on screen with their eyes (and therefore correct the error before going ahead). So we also have to take into consideration those letters which LOOKS less distinguishably different. For instance, I and U are relatively less distinguishable than O and I.
Accordingly, SPIRALFRON.COM is NOT a typo of SPIRALFROG.COM because VERY FEW would mistype G as N (they come from different HANDS, and the keys are not close enough). SPRIALFROG.COM on the other hand is a more likely candidate (though of a different category of typo) because RI and IAL are common character strings in English.
Hope this clarifies a bit.
