It depends on who you are...
If you're a business owner, this certification is a great way to learn demand-based traffic yourself. It's also a great way to train and certify members of your own team to ensure that they're up to speed on the latest trends and best practices.
If you're an agency, this certification is a tangible way to show that you are a Customer Acquisition Specialist, which could help you attract and retain better, higher-paying clients.
If you're a student, this certificate can set you apart from other graduates who merely have a business or marketing degree, but specialized skills that employers today are desperately seeking.
If you're an employee or marketing professional, this certificate can make you more valuable to your company, which is the surest way to get that raise or promotion you likely already deserve (but don't have a tangible reason to request).
