Trade magazine advertising

Trade books run on controlled circulation: copies sent free to a vetted list of people in one industry, audited by BPA Worldwide rather than reader-paid subscriptions.^[1] No trade publisher we reviewed posts a public rate card, so the tier is quote-only. The math that matters is different anyway.

Why controlled circulation changes the CPM

A consumer glossy sells you a million readers, most of whom will never buy what you sell. A trade book sells you eleven thousand plant managers. Divide any plausible page rate by eleven, and the CPM will read as brutal next to consumer print. Wrong comparison. Price it against what reaching the same eleven thousand costs through LinkedIn targeting or a conference booth, and per qualified reader the page often wins. Run your quote through the CPM desk with the audited count as denominator, then judge.

Audits: BPA vs AAM

Both bureaus verify that claimed copies exist. BPA dominates controlled-circulation B2B and its statements break the list down by job title, industry segment and how recently each recipient requested the book.^[1] AAM leans consumer and paid.^[2] Read the recency table hard: a list where most recipients confirmed within a year is an asset; a list padded with decade-old requests is wallpaper. Step 06 walks the statement line by line.

When the page beats digital for niche B2B: the spread. Size economics: full page. B2B-adjacent national titles: Forbes.
