Frequently asked questions
Why doesn't GA4 match my shop's sales?
GA4 and the shop usually differ because of rejected cookies, ad blockers, tagging errors and returns. Part of the gap is normal. A measurement audit separates what is unavoidable from what can be fixed.
What is server-side tracking?
Server-side tracking sends data from your own server instead of from the browser. It recovers events that would otherwise be lost and gives more control over the information shared. It also lightens the website's load.
Which attribution model suits an ecommerce business?
There is no single model for every ecommerce business. GA4's data-driven attribution is a good starting point, complemented by cross-channel comparisons. Webimpacto chooses the approach based on data volume and the purchase cycle.
How does Webimpacto use AI in analytics?
Webimpacto uses AI to detect anomalies in sales and traffic and flag them in time. It also lets you query the data in natural language. The conclusions are always validated by an analyst on the team.
