How to Give Someone a Shoutout on Instagram
Ultimately, the best way to increase your Instagram following is to consistently post fun, interesting or moving photos, but you can help other Instagram users find out about your favorite Instagrammers by giving them shoutouts. Sharing a snippet of another user's Instagram profile and tagging or mentioning that user in the image's caption may encourage your followers to check out the profiles you suggest. If they like what they see, they might choose to follow your shoutout recipients as well.
Log in to your Instagram account and visit the profile of the user to whom you want to give a shoutout.
Take a screenshot of the user's profile page. On an iPhone or iPod touch, press and hold the "Home" button and the "Sleep" button simultaneously until you hear the camera shutter sound. On an Android, press and hold the "Volume Down" and "Power" buttons simultaneously.
Upload the screenshot to your own Instagram account. Select the "Share" tab and choose "Photo Gallery" as your source. Apply a filter, if desired.
Type your shoutout into the caption of the image. Include the hashtag "#shoutout" and mention the person you are promoting by entering the "@" symbol followed by the person's username. For example, you might type, "Follow @friendsusername if you love fashion and funny pics #shoutout."
Tap "Done" to post the shoutout for all of your Instagram followers to see.
