Your Website SEO and paid advertisement like PPC is one of the good strategy for market your eComemrce Business. You can also marketing your eCommerce Business through Social Media Marketing. Cheers
Paid advertising is probably your best bet. You can do a number of things with paid advertising. 1) It makes it easier for you to Split-test and find what converts and what doesn't 2) You can target your audience a lot better then you can with SEO 3) With PPC your traffic is "on-demand" But, if your low on cash, then I would suggest you market yourself on Youtube and display your products if possible. Just take a look at Vat19 on Youtube and model after them. Best Regards, Brain Copy
