In addition, you can dig into the paid side of search and find out what keywords your competitors are bidding on, and then leverage those keywords for your own organic benefit if you're not already doing so.

Nor do you see the “Include specific content” option, which is a life-saver for the adult industry, which spends the most on Google PPC.
