The deck slide

The DOOH slide dies in review for one of two reasons: a point estimate someone checks, or a number nobody can source. Both are preventable. Build the slide from planner output and give every figure its source in the footnote line.

The five rows the slide needs

1. Spend by format and market: the allocation table from your worked plan ($25k, $50k, $100k).
2. Rate basis per line: the cited band applied, with its label: "published band", "vendor claim", or "quote received [date]". Never a bare number.
3. Impression range per line: budget / CPM x 1,000 at both band ends, plus the definition footnote (OOH impressions are estimated exposures).
4. Measurement plan: the metric, the control, the owner, decided pre-launch.
5. Source footnotes: the register URLs. One line: "All rates traced at digitaloutofhomeadvertising.com/proof-of-play, checked July 2026."

Presenting ranges without looking evasive

• Name the driver, not just the spread: "0.97M-3.5M impressions; the spread is the published $5-$18 CPM band, and unit-level quotes will collapse it" reads as command, not hedging.
• Commit to the floor: "we buy only if the quote clears inside the band" turns the range into a decision rule.
• Show the midpoint nowhere. The reviewer who wants one number gets the range and the rule; midpoints are how fabricated precision enters decks.

Backup slides that end arguments

• The source register extract: publisher, URL, vintage, checked date per figure (proof-of-play).
• The fee-stack request and any written answers from your DSP (the two-line request).
• The negotiation position: quotes received, dates, and the standing-bid note per unit (levers).
• The rate board itself for context: /rates, refresh-stamped.

If the plan supports a wider channel argument, keep CAC benchmarks in the appendix too: averagecac.com, framed per DOOH vs paid social.
