also does anyone know how things work in the advertising industry?
Do most companies sign yearly contracts ? are they generally hard to break - how sticky are they .
or do companies sign a lot short term contracts just for 3 months and renew
I haven't ever been in advertising so don't have a great understanding on that side of things

I'm trying to understand if converting customers over to Trafficguard can take a while due to their current contracts having 6 months to expire for example and also if they sign with traffic guard how long they are likely to be , essentially how sticky they are.

I presume it's a mix of both but wondering how it generally works in the industry and how traffic guard is approaching things or is every client case by case
Appreciate any insight
