Sorry Joseph, but do you really think that commercial customers like BBC Wildlife Magazine or Barnes & Noble or companies like Ravensburger (jigsaw puzzles) have time to visit our Facebook pages or personal websites ;-)
If I hear all that, it seems like I've been wasting my time.
I regularly sell fine art prints and posters at FAA because it's a worldwide known business and customers come here looking to buy pleasing art or pictures as if they would visit a store. (I do not promote my pictures via other channels like Facebook, Twitter or whatever)
So, what's the point in wanting to sell licenses if there's no sales department, not even a "store" (read "agency") that commercial clients could visit via a link or button on the well-known FAA? Be serious, commercial companies are not waiting for every Dick, Tom and Harry to present themselves their handful of images. It doesn't work like that.
For me, licensing.pixels.com is like a site - floating in space - while nobody knows it exists.
Bottom-line: you can't market images if they are not seen.
Cheers,
Philippe
