Before I start with my answer, please note that only skills, not certifications are valuable to your employers. If you can demonstrate your skills, you will not need certification that badly. Certifications / courses can only get you in the interview room. After that, only demonstrate-able skills with help you. 

Here are some of the courses that I think you should take for the said cause. 

- Internet Maketing Skills 

- Social Media Marketing both free and Paid

- Search Engine Marketing

- Some basic knowledge of SEO. If you already have that, you do not need certification. 

- Understanding of Digital Shopping Experience (design and execuation)

- E-Commerce Buiness Models Introduction

- Good communication with both who understand your language well and whose you will struggle with. This determines your long term success. 

- Basic understaning of how businesses work

Remember, e-commerce is as much about commerce as it is about about internet. You need skills in both to have a thriving career.
