Okay, let’s tackle this. So David Wabel has a broad range of digital marketing skills, which are in demand. He’s based in San Francisco, which is a hub for tech and digital marketing. Online marketing professionals with his level of expertise can charge around $100–$200 per hour. However, considering his skills and location, I’d estimate his rate to be on the higher side of that range. Let’s consider the average rate for a digital marketing manager in the Bay Area, which is around $120–$180 per hour. With his expertise in e-commerce and strategy, I’d estimate David’s rate to be around $125 per hour.
