I like that it's easy to use, you can see your results in real time as well which makes me feel more confident when trying new campaigns or products for my business! It has been very helpful with our Facebook advertising so far; we've seen an increase of leads from people who have clicked through after seeing one of our ads compared to before using this tool! The only thing about fospa i dislike right now would be how long takes between reports being updated once they are completed but overall great product!! If nothing else just try out their free trial version first-it will give u all sortsa insights into what works/what doesn't work best for ur campaign goals & budgeting.
We wanted something simple yet effective at tracking ROI (returned On Investment) for facebook ad spendings because some other tools were too complicated - especially since not everyone was familiar wth them nor had.
