A directory counts once. Omnera keeps counting.
Both will give you a list of clinics. Only one can tell you which of them changed since you last looked, and show you the evidence.
Providers, captured once
Mixed provider types, broad coverage, and no date on any record. A physiotherapist and an aesthetic clinic look the same, and nothing says when either was last true.
Verified clinics, with a history
Every record is a real aesthetic trading site, checked against its own website, its Google listing and the CQC register. Every crawl is kept, so each clinic is a timeline of dated changes with the evidence behind them.
