Couldn't understand how you use alexa and quantcast data for Facebook Ads. But none of these tools alexa and quantcase is perfect, they have inaccurate data so you can't heavily rely on them.

O.k my friend I`m crating a fb ads for promote a product on clickbank of success life, I'm looking to the public to be interested in the product, if are like men or women and the ages of these people.

alexa and quantcast before these data showed, but today not show we this information someone know how do it?

I hope explain me good my friend

Best regards
