Yes, managing multiple websites under one Google Analytics 4 account can simplify administration and grant a unified view of data, but problems can also arise due to data aggregation and analysis. If each website needs detailed, individual attention and has diverse goals and measurement needs, it would be beneficial to create separate Google Analytics accounts. This way, you’d be avoiding confounding data from different sites and have better clarity on metrics for each individual site. Given that you’ve previously faced issues with merging websites under one account, maintaining separate accounts for each site would potentially serve you better.
