Audit the circulation

You are not buying pages; you are buying copies in hands. Two bureaus exist to prove the copies are real: AAM (Alliance for Audited Media) audits consumer and paid titles^[1], BPA Worldwide dominates controlled-circulation trade books.^[2] A publisher's statement from either is the only circulation evidence worth negotiating on. Everything else is marketing.

The vocabulary

• Paid circulation. Copies readers paid for: subscriptions and newsstand. The strongest signal of reader intent.
• Verified circulation. Free copies delivered to confirmed recipients or public places under AAM's verified rules; real distribution, weaker intent signal.
• Controlled circulation. Free copies to a qualified professional list, standard in trade publishing; the audit's job is proving the list is current (trade folio).
• Rate base. The circulation the publisher guarantees advertisers, the number the rate card is priced against. Reader's Digest publishes a 1,400,000 rate base on its 2026 kit.^[3]

Reading the statement

Pull the most recent publisher's statement and read four lines. Total average circulation against the claimed rate base: a title missing its rate base owes advertisers make-goods, and a pattern of misses means the card is priced on fiction. The paid vs verified split: watch for verified quietly replacing paid period over period. The trend line: compare against the statement from two years ago; the RD kits' own published trajectory shows how fast bases move. And for trade books, the recency table: what share of the list qualified within one year. Ask the AE to walk you through any line that moved more than 10%; the walk-through is often more informative than the number.

Unaudited local titles need the manual drill from the local folio. Feed the audited number into the CPM desk before any rate conversation.
