We have an Expert Tip series that's been great!
I provide my partner managers a Google form with 1-2 questions on a designated content topic (check out our current BFCM Expert Tips blog on
Okendo.io :) ) for them to send out to their selection of partners.
Once we write the piece based on the partner's answers, we created a social asset that includes the author's agency logo, name, headshot, and quote in the piece. We ask them to promote the blog with us, and since we've provided everything they need and added a personal touch with their individual information on it, it's hard for them to say no! We find we have a "social takeover" whenever we release one of these pieces, which is really exciting to see.
