We’ve had some reports for our editors that they see many paid ads in Safari on iOS, but almost no paid ads on a desktop Safari on OSX.
I’ve gathered some data from those who have Macs here, but no data for iOS devices yet, and the trend is that for most people if Safari is their primary browser and they are pre-Safari-11 they get good fill. Post-Safari-11 seems to generally get poor fill. But there are some anomolies that get great fill on Safari 11, even if they use Chrome almost exclusively.
My questions to you:
- Have you seen good fill or poor fill for paid ads on desktop OSX/Safari when it’s not the ‘primary’ browser (meaning not used much and therefor doesn’t have a lot of user data cookies)
- Do you have any thoughts on why Safari 11 on iOS would have good paid ad fill for a user, but for that same user on Safari 11 on desktop they would get really poor paid ad fill?
