Google Analytics is a great way for tracking data from your website. They offer free courses where you can learn about various aspects. I took the fundamental courses where i learned about conversions, key metrics and dimensions, filters, AdWords, ecommerce reports, and much more.
Each lesson has a video, as well as a text transcript, followed by a few short questions to test what you just learned. They also provide additional readings if you are struggling with specific sections. I thought the course was structured well and made it possible to get the most out of this learning experience.
You can become Google Analytics Certified by taking a free 70 question exam to prove your knowledge. Instead, for our class, we took a test that just tested our knowledge pertaining to the fundamentals course. Above is a screenshot of my results. If I were to become certified, however, this would be a valuable asset to include on my resume and may set me above from other applicants. I may still choose to take the test later when I start applying for other jobs and internships that pertain to Advertising.
