Are these suitable for an e-commerce brand?

If your brand has a social media presence on Instagram, Facebook, LinkedIn, etc and you want to grow your reach, engagement, followers and customers, then absolutely these are perfect for you and your brand.

For example, if you sell health supplements, that doesn't mean you can't create viral worthy educational content ABOUT the topic of supplements. 

In fact, content marketing has been proven to sell e-commerce products even better than just direct response advertising.
