How Typosquatting Domains Are Built
Typosquatting domains are typically generated through a small number of predictable patterns: single-character omissions or additions, adjacent-key misspellings, transposed letters, added or removed hyphens, and homoglyph substitutions using visually similar characters. Investigation starts by mapping the full set of plausible variants against what has actually been registered, then documents how each was used.
Tracing the Monetization Chain
Typosquatting is rarely valuable unless monetized, and the monetization method is itself evidence of intent — pay-per-click advertising networks, affiliate-redirect schemes, direct competitor advertising, and phishing pages each leave a distinct technical fingerprint that can be traced through redirect chains, ad network identifiers, and hosting infrastructure shared across a registrant's other domains.
