  "summary": "Convert billboard lease price and traffic count into cost-per-thousand-impressions for advertiser comparison.",
  "description": "Advertisers compare out-of-home media against digital and broadcast using CPM — cost per thousand impressions — so pricing a billboard competitively means converting traffic count into an impressions estimate and dividing lease cost by it. The Traffic Audit Bureau's standard method applies an audience factor to average daily traffic to account for vehicle occupancy and repeat exposure, since not every car passing counts as a fresh unique impression in the way a media buyer thinks about it. This calculator takes daily traffic count, an audience/visibility adjustment factor, and monthly lease rate to compute monthly impressions and CPM, so both the sign owner and the advertiser can sanity-check the rate against other media CPMs.",
  "formula": "Monthly impressions = daily traffic × audience factor × 30.4. CPM = (monthly lease rate ÷ monthly impressions) × 1000.",

  "faq": [
    {
      "q": "Why not just use raw traffic count as impressions?",
      "a": "Not every vehicle occupant looks at the sign, and industry measurement (Eyes On methodology from the Traffic Audit Bureau) applies adjustment factors for vehicle occupancy, sign visibility, approach angle, and travel speed. A 45% audience factor is a reasonable simplification for a well-placed, legible highway board."
    },
    {
      "q": "How does billboard CPM compare to other media?",
      "a": "Out-of-home billboard CPM commonly runs $2-$10 depending on market and location quality, which is competitive with or cheaper than local broadcast TV and often cheaper than premium digital display, though it lacks digital's targeting precision — the pitch to advertisers is broad, repeated local exposure at low cost per impression."
    },
    {
      "q": "Does a higher audience factor always mean a better sign?",
      "a": "Yes for CPM purposes — a lower-traffic sign with a very high audience factor (slow traffic, long dwell time, like near a stoplight) can beat a high-speed highway sign on effective attention per impression even if raw traffic is lower, which is why local pricing varies more than traffic counts alone would suggest."
    },
    {
      "q": "How should I use this when negotiating a lease rate?",
      "a": "Calculate CPM at the asking rate and compare it to other local out-of-home CPMs and to what advertisers are already paying for local radio, streaming, or print in your market. If your CPM is meaningfully above local competitors' out-of-home CPM, expect resistance unless traffic quality or exclusivity justifies the premium."
