If you have other platforms, use them to direct traffic to your Instagram. The most simple way to do this is to add a link to your Instagram account in the profile section of your other social media accounts. You can do this on pretty much any channel, including Facebook, Twitter, TikTok, Twitch, LinkedIn and YouTube.
Don’t feel the need to limit your cross-promoting efforts to social networks though. Try embedding Instagram images in blog posts, on websites and in newsletters and emails. The images will add visual appeal and also make it easy for customers to find your Instagram account. Another option is to add a link to your account in your email signature. Have a podcast? Be sure to advertise your account on there too.
