Source

What qualifies
Company records associated with the United Kingdom whose business descriptions match “advertising research firms” by meaning at the Exact setting.

Match quality
RevenueBase's August 25, 2026 study assessed 4,198 description/company pairs across matching settings. The publisher reports 86% good or better at Exact.
