What a Fair Website Traffic Comparison Requires
A fair comparison uses the same metric, date range, geography, device scope, channel definition, and bot filters. Comparing one site’s users with another site’s sessions or one month with another quarter creates a larger error than most calculation choices. Normalize definitions before interpreting the difference.
TrafficChecker compares visits and conversion outcomes because volume alone can reward low-quality reach. The calculator is suitable for two periods of the same site, two campaigns, or two defensible competitor estimates. Keep third-party competitor values labeled as modeled data, not private analytics.
