About
Proof of airing for Nigerian radio.
Spotledger is a business to business product. It listens to radio stations day and night, recognises the adverts it hears, and proves it to the companies that paid for them.
What Spotledger is
A listening service for the people who buy radio.
Agencies and brands upload their adverts and their media plan. Spotledger logs every airing with the station, the time, the length and which fingerprint found it, compares the airings with what was booked, lists the spots that were not detected so a buyer can claim make goods, and issues proof of airing reports.
Because Spotledger also transcribes what is said on air, it can check presenter live reads against a script and find adverts that nobody uploaded, including a rival's.
Why
Buyers pay for spots and cannot easily see them.
In 2016 a Nigerian monitoring firm said compliance could be as low as 35% at some stations and that over 90% of advertisers did not monitor their airings (BusinessDay, 2016). That evidence is old and from a vendor, so read it as context, not as today's rate.
Audience measurement says who was listening. Spotledger answers the other question buyers ask: did the ad air as booked?
How we work
Six habits.
01
Say what we know, and how we know it
Every number on this site is measured from our own recordings or quoted from a named source with its year.
02
Show the gaps
Minutes we were not listening are shown and left out of the score. A gap in our listening is never blamed on a station.
03
Never accuse
We say Not detected in a fully monitored window, next to the minutes we were listening. Any line can be disputed.
04
People confirm what is new
Software records the streams, Spotledger AI reads and names what is said, rules check every answer, and a person confirms new brands and unsure matches.
05
Keep clients apart
One client's adverts, plans and results are never visible to another.
06
Names, not logos
We show station and brand names as plain text and use no logos without written permission.
Where
Lagos and Abuja.
Radio only: 12 stations in two cities, recorded from their official online streams. Live reads are checked in Nigerian English.
