As a creator you can see who paid and when at what time how much was paid exactly this is only visible to the Creator this is very easy to keep track of who paid what, more can be found in settings in the APP
Everything can be seen and an overview from month to month so that you can keep track of how much is earned per month. to set a goal for yourself in this way to earn more than the month before, that is why the app is so POPULAR because it is clear and transparent
It is also easy if you know who exactly is buying your content because you can then send your fans paid content in a targeted manner, but you will often see that the fans themselves already come with requests for photos or videos.
OnlyFans also shows exactly where your fans come from who have visited your profile, and via which channel this is, via social media or via the internet or other channels and which visitors have visited and viewed your profile.
You can also see exactly how long they have viewed your profile, this cannot be seen separately per profile visitor, but the total time of all visitors over the past 24 hours, if the data is not visible, reload the app until the data is LOADED, this is of course handy to see, so you exactly know on which platforms or internet websites you have to focus to get more visitors and fans.
