What are the globally accepted Internet Marketing certifications?

Website addresses will be good. I have googled but am unable to find a PMP equivalent in Internet marketing.

There is no such measure in digital marketing and in fact only a handful of schools offer any sort of specialization in digital for business / marketing / mba programs. You can of course find some certificate programs but I’ve never given much weight to those and certainly not vs work experience or an internship. Marketing is much more about understanding people’s behaviors and motivations and then learning specific tools to address them than a formalized study.

The role of digital in education will certainly shift but I don’t suspect you’ll see anything like PMP - there’s never been such a concept for traditional marketing and it doesn’t make any more sense with digital.
