What value do you provide?

What should they do next?
Visit your link, DM you, book a call, or shop.

Why Your Instagram Bio Matters
After your username and profile photo, your Instagram bio is the first text a new visitor reads. That should explain who you are, what you offer, and why someone should follow or take action. The big deal is it should cover this entire thing within 150 characters only.
When it comes to businesses, the bio should support discovery and conversion. It should mention your core service, location (if relevant), a clear differentiator, and one direct action. For creators, it should establish the content promise and make following feel worthwhile.
