I've taken a number of digital marketing courses by Jeff Sauer and Jeffalytics in the past, and his PPC Mastery Course is the best PPC and Google Ads training I've ever taken. In just a few lessons I've gotten more takeaways on how to improve my ppc campaigns, tighten up my ad groups, and improve conversions for both my own business as well as my digital marketing clients. Anyone who is looking to take their PPC skills to the next level will find this course incredibly useful, and if you haven't taken your Google Ads certification yet, the team at Jeffalytics helps you study and prepare for the Google exams in an understandable way that builds upon your PPC knowledge. Would highly recommend the PPC Mastery course and any ohter courses from Jeff Sauer for all digital marketers.
