What makes an Instagram caption convert
A high-converting Instagram caption has three parts: a hook in the first line that stops the scroll, a middle that delivers value or emotion, and a clear call to action that tells people what to do next. Keep it specific, match your brand voice, and add hashtags only when they fit the topic.
