Thanks! Yes, I handle everything except writing the actual content. That includes PPC, SEO, and making it easy for my mom to promote posts via Pinterest and Facebook (Pinterest is responsible for our success by the way).

Most of the revenue comes from the Amazon Affiliate program, but recently we've been making a decent amount off of display ads from the BlogHer ad network. Google AdSense contributes a little bit as well.

As for SEO, I wrote the blogging software from scratch (I don't like Wordpress) so the SEO is entirely under my control. I'm no SEO expert though, so I'm sure there are many things I could be doing better.
