QWERTY Replacement

Replaces characters with their neighbors on a QWERTY keyboard layout, simulating fat-finger typos.

How It Works

This technique replaces each character with its neighbors on a QWERTY keyboard. For example, "e" is adjacent to "w", "r", "s", "d" on QWERTY, so each could replace it. This simulates "fat finger" typos where users hit a nearby key instead of the intended one. It generates many variations because each character has 2-6 neighbors.

Real-World Examples

  • googlr.com ("e" replaced by "r", adjacent on QWERTY)
  • fscebook.com ("a" replaced by "s")
  • twutter.com ("i" replaced by "u")

Prevention Tips

  • Focus on registering replacements for the most commonly mistyped characters in your domain.
  • Consider that different keyboard layouts (QWERTZ, AZERTY) produce different replacements.
  • Use DNS monitoring services that check for keyboard-proximity variants.
