The default starting point for websites
Web tracking · Reports · Integrations · Free
GA4 is the free standard for web analytics — search traffic, acquisition, and user behavior on any website. It's not the easiest tool to master, but the price (free), ecosystem integrations, and sheer data volume make it the obvious starting point for most businesses.
