Track the response

Print is measurable if you instrument it before it runs, and unmeasurable forever after. Four instruments, all cheap: a vanity URL, a promo code, a dedicated phone number, a QR code. Every ad carries at least two. The renewal decision in three months is only as good as the plumbing you lay this week.

The instruments

• Vanity URL. A short memorable path (yourbrand.com/magazine or a dedicated domain) that 301s to a landing page with campaign parameters attached. Print-only, never used elsewhere, or the data is soup.
• Promo code. Title-specific and offer-bearing. A code that saves the reader money gets typed; a tracking-only code gets ignored and your response undercounts.
• Dedicated number. A call-tracking number unique to the title. For call-driven categories this is the primary meter, and per-inquiry print (Step 04) is built entirely on it.
• QR code. The lowest-friction bridge to mobile; mechanics in Step 10.

The matched-market test

The clean experiment where geography allows it: run the ad in the title's edition covering market A, hold out comparable market B, and compare branded search, direct traffic and sales lift between them over the issue's life. Regional editions (MNI-style buys) and city titles make this practical at SMB budgets. It is the strongest answer to "did print do anything beyond the codes?"

Windows and assisted credit

A monthly issue lives on tables and in waiting rooms for weeks; industry effectiveness material argues long tails for magazine media, though remember who funds it.^[1] The desk convention: hold the response window open at least 60 days past on-sale before judging, and log code and vanity-URL activity weekly so the decay curve is visible. For assisted conversions, be honest in both directions: a reader who saw the page and later converted through paid search is partly print's win, and your last-click report will hand all credit to the click. Watch branded-search volume over the issue window; it is the cheapest assist meter that exists.
