I started Good Impressions, which helps effective nonprofits and foundations scale using paid ads and SEO.
For me, the takeaway is that the actual cost of generating interest in EA (Brian's $4 cost per graduated EA fellow from below) is significantly below our little group's estimates of what an engaged EA is worth ($3K -$30K as noted above).
I think everyone would agree an engaged EA is worth more than $4.
If someone is reading this who would know how to scale FB ads for EA university fellowships that seems like an extremely high impact thing to do.
I have domain expertise in digital marketing and would love to help EA organizations. I'm not qualified to weigh in on the questions of messaging or how far-reaching the campaign should be, but once those things are figured out I can tell you the best way to use YouTube and Google Search to accomplish your goals.
