Monthly Unique Visitors is the sum of devices visiting the analyzed domain, within the country and time period analyzed.
Unique Visitors is the foundation of many of our other traffic and engagement metrics. We calculate Unique Visitors for desktop and mobile web in the exact same way. All traffic is the sum of desktop and mobile web unique visits (not deduplicated).
Use Unique Visitors to assess the actual reach of a website. Compare this metric to Total Visits to understand repeats vs. new visitors. Compare Monthly Unique Visitors to Daily Unique Visitors to see how often users visit a website throughout the month.
