misomoon vs Google Analytics 4

  1. 1

    Sign in with Google under Settings > Import and import your GA4 property’s history.

  2. 2

  3. 3

    Connect Search Console to keep your Google search terms.

Questions

Can I keep my Google Analytics history?

Yes. misomoon imports a GA4 property’s history, and the imported numbers show next to the ones misomoon collects.

Why are misomoon’s numbers lower than GA4’s?

misomoon drops known bots and counts only real requests, with no modeled data.

Do I still need a cookie banner?

misomoon sets no cookies and stores nothing on the device. Whether you need a banner depends on your country and the rest of your site. This is not legal advice.
