TrustedFirmsThe agency record

Research

We publish the numbers behind the market we cover. Every figure is attributed and dated, every number we worked out ourselves shows its arithmetic, and when sources disagree we explain the disagreement instead of picking whichever one reads best.

The same standard we hold the agencies to. It would be hard to tell a firm its evidence is not good enough while publishing unsourced numbers ourselves.

How we source

Every figure is labelled with what kind of source it came from, inline, next to the number. That matters more than it sounds: a government survey and a vendor’s estimate of its own market are not the same evidence, and most statistics pages present them as though they were.

Across the reports here, that means:

  • government statistics
  • vendor estimate

Where a source is self-reported or not independently audited, we say so next to it rather than in a footnote nobody reads.

Why a directory publishes research

Because the two jobs are the same job. Working out whether an agency is good at what it claims and working out whether a market statistic is true both come down to: who says so, how would they know, and when did they measure it. The method behind the directory is published in the same detail.
