Relying on FB&amp;#x27;s targeting algorithms is tactical - that&amp;#x27;ll give you great targeting once the time comes to execute your campaign.&lt;p&gt;But CA data, even if noisy, has been exfiltrated out from under privacy controls, so that you can get a much more direct look at it. That allows an analyst to get a more detailed sense of what social networks actually look like. I imagine that is more useful for figuring out what kinds of people you should be targeting in the first place, in order to maximize the leverage of your campaign.</text><parent_chain><item><author>cm2012</author><text>I&amp;#x27;m a professional FB marketer and have managed both large budgets for private companies and also done political campaigns.
