I have an online store which built based on WordPress and eCommerce but on marketing aspect it has traffic and has not generated enough sales monthly. I want to know what are the best methods to promote an online store?
It doesn't matter what traffic platform you're using, you simply need a good marketing strategy.
For instance, from a musician point of view. I attract customers by selling them the cheapest stuff first like selling them 2 or 3 songs for around $2.99 instead of selling them an entire album for around $19. Once they buy the cheap stuff like a single song for maybe $0.99 then I use email marketing to sell them the other high priced stuff like full length albums and merchandise (t-shirts, hoodies etc.).
After they buy the cheap stuff, make sure that you customize your receipts by adding upsells. Send traffic to the cheapest product on your store and use email marketing to sell the high priced stuff. That's how you do e-commerce.
Hope that helps
