While Google Analytics offers comprehensive reports on all global traffic to your site, Maximise focuses specifically on identifying and enriching data from your anonymous visitors, with a special emphasis on US-based traffic. Maximise typically identifies around 20-40% of these visitors.
It's important to remember that Google Analytics and Maximise serve different purposes. Google Analytics gives you a wide lens on overall website activity, while Maximise hones in on detailed identification and enrichment of your visitors, turning anonymous users into actionable insights.
To compare, focus on the number of daily unique US visitors in Google Analytics. Maximise should identify about 20-30% of this segment, giving you a deeper understanding of your US audience and potential leads.
