Taxi advertising · the real-reach worksheet

Taxi advertising's real math, the part vendors leave out.

Taxi-top advertising is real but oversold: vendors quote a huge impression number, but only a small fraction becomes genuine reach. This worksheet runs one day of roughly 25 digital taxi tops down the funnel — impressions to real reach — so you compare on cost-per-memory, not the headline CPM.

Vendors sell you a big impression number. This worksheet runs one day of roughly 25 digital taxi tops down the funnel, line by line, to the real reach you actually buy.

Impressions quoted 100,000
Actually seen 38,000
Conscious view 11,000
Remember the brand 1,400

Why the gap

An impression is not a memory.

Out-of-home vendors sell "impressions", every person who could have seen the cab. But an opportunity to see is not attention, and attention is not recall. Industry funnel data shows the drop-off is brutal: of the people a moving ad passes, only a tiny fraction walk away remembering the brand.

    Speed, angle and clutter cut the rest before anyone looks. Geopath

  3. 25–40%

    Of those who could see it, only some actually process the ad.

This is what an "impression" looks like in real life: a glance, at walking speed, in clutter.

That is not a reason to avoid taxi advertising. It is the reason to buy it on real reach and cost-per-memory, not the impression count. See the full breakdown →


The split vendors blur

Exterior is broad and shallow. Interior is narrow and deep.

Rooftop tops and wraps reach a whole city, but most people only glance. Interior and rideshare screens reach far fewer people, but those riders are seated, captive, and verified.
