How to read a media mix without an analyst on staff

You do not need a measurement studio on retainer to stop a bad claim leaving the building. You need three pages you can assemble from files you already receive.

Page one: spend as a calendar

Ask for invoices or a simple export with date, channel, and amount. Put them on a week grid. If “always-on social” is a single lump for the quarter, ask for a split. A mix you cannot place in time is not a mix; it is a total.

Page two: the outcome you already believe

Not clicks. The series the commercial meeting already uses: net bookings, completed applications, store receipts. If that series is monthly and the media is weekly, say so at the top of the page. Do not interpolate a pretty line because a charting habit expects one.

Page three: claims the pack is not allowed to make

Write the sentences the agency (or your own team) may not use without a join: “this placement caused,” “we generated,” “ROI of.” Replace them with “this placement ran in these weeks” and “these outcomes occurred in these weeks.” It feels like a demotion. In a leadership slot it is a relief.

If those three pages still leave a decision hanging, that is a reason to commission a measurement review, not a reason to decorate the pack with more channel metrics.
