Marketing on Instagram is not as easy as it might sound. If you wanna sell on Instagram, you MUST do it the right way. From your profile to your posts. Photo, caption, hashtags. Everything is part of your marketing. Just posting stuff is not enough. The kind of followers you already have, but also the kind of new followers you want to attract are integral part of your Instagram marketing too. Everything matters. Even what you do on Instagram. Being social is the big trick of Instagram marketing. Show up, be social, make friends. Like if you were at a party, not like a market. Business is done by building relationships, not by yelling low prices and high followers count. Reach a lot of people, but engage with them. This is how you sell on Instagram.
