For many months I and a few other engineers at Facebook have been building a new reporting tool for advertisers. This involved both a huge amount of work to build a fast, flexible backend that lets you slice your data in almost any way you can think of, in real time, and a UI to match.
I’m really proud of this work, which involved building a DataTable that can handle an infinite number of rows and columns, in place column reordering, resizing and all the other fun stuff that goes along with it.
If you run ads on Facebook, give it a try. It provides an unprecedented level of detail on the performance of your campaigns including how much you’re paying for the actions that you care about, such as mobile app installs, page likes etc.
Some press about it:
