There are several ways to get Instagram analytics for your business account. First, you can use the native analytics provided by the Instagram app itself. This will give you more intel on the type of content that performs best, your audience's makeup, engagement rates, etc.
The second way is to use a social media marketing tool that not only provides you with analytics of your own content but can offer opportunities to track your competitors, benchmark results against industry averages, and so on.
The third way is to use an automated reporting tool like Whatagraph. This way, you’ll be getting in-depth analytics of your own Instagram performance. And you’ll be able to link up Instagram with other social media or marketing channels in a single report to get a better understanding of how your overall marketing strategy is working, what’s the ROI, and which areas can be improved.
