Well, as a guy involved in digital marketing I can tell you that it isn't idiotic. But the topic title really is weird. Naming photo session a "digital marketing" is profanation. Because digital marketing is about making a lot of content, making SEO, making external links on different forums and other stuff like that. Not so long ago I had bought some backlinks for my site from these https://crowdo.net guys and it made my site's page rank grow. I don't think that the photo set can make something similar, lol. It could have made my site looking cute, but that's all.
