NumberHill is an innovative web analytics solution that incorporates revenue attribution seamlessly. This platform connects online traffic to transactions processed through payment gateways like Stripe, LemonSqueezy, Polar, Shopify, and Dodo Payments, allowing users to see the actual revenue generated by each marketing channel, webpage, and campaign based on revenue per visitor rather than merely tracking bounce rates. A single script is utilized to capture each visit along with its source and UTM parameters, ensuring that the visitor ID is included in your checkout metadata; the payment webhook then correlates sales back to the original visit, thus attributing revenue to the proper channel, including refunds. Key features encompass revenue per visitor analysis segmented by channel with options for first-touch and assisted credit, differentiation between paid and organic traffic sourced from identifiers like gclid and msclkid, AI insights revealing visitor behavior and revenue derived from sources like ChatGPT, Perplexity, Claude, and Gemini, alongside robust bot filtering that excludes 49 identified AI crawlers and scrapers from the analytics. Additionally, NumberHill offers a real-time feed of visitors, tools for funnels, goal tracking, and retention, as well as webhook automation capabilities, supporting both cookie-based and cookieless tracking methods, and facilitating easy agency client handovers. With subscription plans starting at just $9 per month and a 14-day free trial available, it provides an accessible entry point for businesses seeking to enhance their marketing effectiveness.
