What is the minimum to advertise on a billboard?

Published floors: Blip has no minimum spend and a $0.01 per play auction floor; Adomni has no minimum budget for nearly all inventory; Blindspot lists campaigns from $50. For traditional flights, AdQuick publishes small-market digital under $1,000 per 4 weeks and Blip cites $250 rural traditional leases.

Is a $50 billboard campaign worth running?

As learning, maybe; as marketing, no. $50 at Blindspot's ~$0.52 median play price is about 96 plays. Use micro-budgets to test creative and platforms, then judge the channel at a spend big enough to measure, typically four figures and up.

Is the floor spend measurable?

A $20/day Blip budget is 2,000 plays at the floor, roughly 38 at the $0.52 busy-screen median Blindspot 2026: enough to test creative and clearing prices, far too little to move branded search. The honest ladder: floor spends to learn the platform, four figures to learn a market (small markets stretch furthest), and the $25k structure to judge the channel. Route economics: platforms.
