Tracking and understanding website statistics, analytics and user behavior using most tools is very complex & time-consuming, especially for non-technical people. You have to install and use many tools in parallel, retrieve data from different repositories, and then compare them all. It’s easy to find yourself stuck in an overwhelming amount of graphs and charts. This is why we developed Visitor Analytics: all the tools you need, united into one app. A user-friendly structure, a straightforward presentation of complex data, and simplifying your work with  data synergy between modules!

We are 100% GDPR/CCPA compliant and collect all the data a website owner needs to know about their visitors in real-time: referrals, conversions, bounce rates, click paths, traffic structure, social media interactions, custom events, page visits, IPs, locations, browsers, devices or OS used, and much more. And get more value from the app by using our visitor behavior analysis tools: session recordings, conversion funnels, and heatmaps. Receive feedback from your website’s visitors with almost no effort using our amazing poll and survey features. Our app is built for entrepreneurs, marketers and companies focused on their site statistics, visitor behavior, and interacting with their website visitors. Stay tuned for more useful modules; we’ve always got a new feature right around the corner.
