Tool to track reach?

Let’s say you’re giving a monthly client report, and you’re telling them how many impressions and how much reach you’re getting.

In the insights tab you can only see weekly impressions/reach, so does anyone know of a tool that can track it monthly? Or pull insights once every week and use it to build up a graph?

Thanks!

Hmm im not sure if this one goes that far back but check out if the Facebook Creator Studio allows you to see those numbers when logged in with the client account. Log in on one of your accounts to see

Or with later.com paid plans I think it allows you to see those numbers

As an agency owner I use both of those tools and I haven’t been able to do what I described. It shows week to week insights just like the Instagram business insights do, but it doesn’t store the weekly insights and add them up.
