I’m not usually a big fan of auto-posting content from one channel to another. However, in the case of Instagram to Facebook, I would say go for it. Now that Facebook owns IG, they’ve made it super easy to auto-post your photos to a business FB page. Photos display in full dimension, with tags.
When posting to IG, remember that high quality photos are a must. Use your artistic eye to take something unique, not seen every day. And if you are using IG for business, don’t just take photos of your products every single day. Tell the story of your business. Tell the story of a typical day for you, as a business owner: patronizing other businesses, connecting with your community. What do you do on a typical day off?
Social media marketing is just that, marketing. Marketing is not sales, but sales is a part of marketing. So don’t make every post like a commercial for your business. Think of all your social channels more like lifestyle blogs. What is the lifestyle that your company represents?
