Monthly Unique Visitors


Monthly Unique Visitors is the sum of devices visiting the analyzed domain, within the country and time period analyzed. 


SimilarWeb calculates a unique visitor based on the visits of an anonymous unique ID over the period of a month time. Unlike other traffic analysis tools, SimilarWeb does not rely on cookies, which is considered an unstable technology since it is susceptible to being manually or automatically deleted. For that reason, cookie-based technology will tend to overestimate unique visits, and therefore show a higher number than what you will find in SimilarWeb data.

Using this metric

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. 


This view is useful for:

  • Strategy and investment teams measuring a brand’s reach
  • Publishers assessing the exposure for a competitor’s piece of content
  • Advertisers quantifying the impact of another company’s campaign
