The Benefits of Google's GA4 Analytics

Google Data Studio gives you the opportunity to take both sets of data in there and then see the anomalies. How far should an SEO go back to make sense of that data? Are you talking about over a year? I personally would do. The last couple of years for every industry has been different compared with how it used to be. For many campaigns, the best year on year comparison tends to be against 2019 because 2020 and 2021 was so unusual.
