Facebook Advertising Bootcamp


Attended: Facebook Advertising Bootcamp

I am sure there is more information in the deck that we will receive, but the class itself lacked substance. Of the multiple topics scheduled to be taught (Custom audiences, Bidding Strategies, FB Pixel, measurement, and integrating with other channels), we only covered Custom Audiences. I was really hoping to dive deeper into the FB pixel and measurement, but there was very little mention of that. Overall, I would only recommend this course someone who has new to FB promotion.

I was hoping to learn more about how to use the Facebook Business/Ad Manager. This class seemed helpful for those looking to market tangible products, but less so for marketing for a performance venue. It was more aimed at finding consistent customers for consistent products, with little practice using the tool. Less of a how-to than other reviews had led me to believe.

I was very disappointed how the class was run and how the teacher prioritized different subjects. while the teacher might have been a digital marketer himself doesn't mean he is qualified to teach.
