When viewing this image, two conclusions can be drawn:
- Google was wrong, so the ad serving algorithm is not tuned to Angolan companies.
- Movicel associated the display of its advertisements with the keyword “Unitel”.
But this is only hunches. Anyone have any better?
If you notice it has a yellow background where Movicel appears, that means it is a yellow page or an announcement (Paid) to be there, in this case, the public something of Movicel are also Unitel customers, it is not a sin to look for services from Unitel and I offer you MOVICEL, movicel has associated your name with anyone looking for UNITEL, it's business.
I liked the comment @DinoCross, it ends up explaining a lot and also showing the Business side (Vision) of Movicel…
