I've been in that situation where I've let an opportunity to take advantage of incoming traffic pass. Useful to see new referrers or suddenly popular pages.
I'm building something similar around Google Search Console.
I believe there is a lot of opportunity around presenting this type of data in a more usable way.
Yes. Even more so for experienced users. Probably have the most to gain and less time to spend analyzing analytics data. One other marketing segment/pricing structure to consider: web design/development agencies wanting to offer services like this to clients. It could keep clients engaged and demonstrate effectiveness of projects.
I signed up for the free tier to try it out. Some things to consider: At first glance, your pricing page seems to imply the monthly price is the annual price. You may want to change "annually" to "monthly" and then mention that it is billed annually. Your landing pages look good, but you may want to have some additional grammar checking done on the alerts page (I suspect English is not your first language?)
My project is live, but definitely in early stages. The reports work best for sites with a decent amount of traffic: https://clickpost.io
