AdLibrary Helper is a free Facebook ad spy tool. Its data comes from Facebook's official ad library. It can provide you an advertising list, which is more convenient and practical than the Facebook ad library.

I wanted to create lots of long-tail keyword combinations/permutations based on a few primary keywords, and couldn't see any easy way of doing it, so I wrote a quick script. I figured it might be useful for others so I put it up on a the internets.
