Five Monday Numbers for DTC Owners Before Black Friday

Eleven Mondays remain before Black Friday 2026, from 14 September to 23 November. The Price of Being Found names five numbers that require no vendor, come from data you already own, and together answer the question a CFO is actually asking, which is not "what was the ROAS" but "how much of this do you actually know". Establishing them takes a quarter in the book's own protocol. Compressed to the Mondays that are left, it takes three weeks of afternoons and then one test.

The appointment is the mechanic. Octalysis's Appointment Dynamics works because a fixed recurring time makes the action happen; a Monday number that is read every Monday gets computed. The five below are the ones worth the slot.

The five

1. Coverage. Attributed conversions divided by actual orders from the store, by month. The share of your sales your measurement can see. Reported cost per sale is the real one divided by this number, so a level of 0.6 means every cost figure you read is 67% above reality. The number nobody checks is the long version.

2. Visibility rate. The all-in cost of being found, divided by gross merchandise value. Media spend, plus marketplace commission, plus mandatory or quasi-mandatory ad programme fees, plus payment processing, plus fulfilment fees that depend on placement, plus the measurement stack and the agency retainer attributable to paid channels. Twelve months of it, split by component and ranked by growth rate. The book's observation: the fastest-growing line is almost never the one under negotiation.

3. Claim ratio. Every platform's claimed conversions summed without deduplication, divided by orders. Above 1 for most multi-channel brands. Track its level once and its movement always, because movement is usually a definition changing rather than performance changing. The one-hour audit computes it.

4. Mix-adjusted unit cost. Your blended cost per unit, and beside it what it would have been at last year's mix of placement, country, format and objective. The difference is the mix effect in euros, and it is the honest answer to "did media get more expensive or did the platform rearrange our buy".

5. Anchor date and MDE. The date of the last holdout that qualified against the measurability floor, and the smallest lift it could have detected. If there is none, the entry is "never", written in the same place as the other four.

The eleven Mondays

The holdout is the only step with a hard date, and the date is set by the arithmetic: eight weeks live, ending before 27 November, on the channel with the largest margin over its floor. The last day to start it is 2 October.

What the first reading will look like

The book warns that the first time you present these, marketing will look worse. Coverage lower than anyone expected. Visibility rate higher than the media budget suggested. Claim ratio above one, meaning the platforms collectively took credit for more sales than the company made. Anchor date "never". It calls that the correct first result: it is what the situation was before you measured it, and a smaller number you can defend is worth more than a larger number you cannot. The second quarter's version is better because the first one existed.

What to do this week

• If you own the budget: block ninety minutes on Monday 14 September and compute the first two. Neither needs anyone's permission.
• If you have to defend it: put the five, with blanks, on the front page of the Q4 plan now, so the blanks are visible and the Mondays fill them in.

The calendar has the dates. A causal read on the GA4 export is the fastest way to get an incremental figure with an interval for every channel between anchors; it does not replace the anchor.

As of 9 September 2026. The five numbers and the week-by-week protocol are from The Price of Being Found (Edition 2.10), Chapters 19 and 20, compressed here to the Mondays that remain.
