About The Conversion File

The Conversion File. The Conversion File is evidence-led digital marketing: what was run, what it did, and what we would not do again.

Every article that carries a number or a date traces it to a named, live source — government announcements, exchange-rate and market data, or UK news reporting — rather than an invented figure. Where we comment on a story, we link the original so you can read it yourself.

Articles that don't meet our own grounding and quality bar aren't published. Nothing here is financial advice.
