Best Instagram bot to promote your business is InstaCaptain . Grow your followers on Instagram and use it to promote your business or app. It allows auto follow, auto like, auto comment, auto post or scheduler you can say and many other filters and targets to grow your Instagram Account .
You can use follow/unfollow strategy to grow your account or auto liking feature. This helps in growing your account. You can also use Auto Dm to message influencers in bulk and ask them to be your affiliates.
Though Instagram bots are useful but when it comes to influencer marketing, it is important for a blogger to connect with his audience to build that trust factor. The audience should feel that they are interacting with a real human and not a bot. May be bots are important when you are just building followers but for influencer marketing, bots are no real help.
