Digital advertising has defined rules but is also a trial and errors process. This is why you have to monitor your results very carefully.
There are endless on-line sheets to record and measure the effects of your efforts.
Don’t forget to include in your analysis date and time of publication, if you posted a picture, a video or an infographic, the number of views, likes, and interactions.
All this information is easy to find on Facebook ads manager. All the data that you will collect will help you understand what is working and what is not in your digital communication. It might sound simplistic, but stop doing what is not working and repeat what is giving you good results!
