ByDiscovery does not replace Google Analytics. It is ideally recommended that ByDiscovery be combined with a web analytics tool on your website.
In Google Analytics, you can see which pages your visitors' visit (for instance, the pages that have the highest rejection rates or conversion rates), but you don't see who they are.
With ByDiscovery, you can serve a personalized discovery checklist to your website visitors using the ByDiscovery Widget. As a result, you will be able to generate more leads and get more customers.
