To those of you who want to learn more about digital marketing I recommend to sign up for Google’s Digital Garage. You will find free courses on topics such as search, analytics and social media. Once you have completed all 23 topics, you will be awarded with a Digital Garage Certificate of Online Proficiency issued by Google. There is a multiple-choice test at the end of each section. The courses are made for ‘everybody’ with an interest in digital marketing, so it is not too difficult to pass the tests on the first attempt. Anyhow, mistakes are allowed.
