What's the meaning of Audience Overlap and Audience Loyalty?

Audience Overlap allows you to identify which percentage of your visitors also visit your competitor's site. Understanding the size of overlapping audience sets in a given competitive landscape allows you to detect leaders, emerging threats, and opportunities. Audience Overlap insights also give you a picture of your total addressable market, highlighting your unreached potential visitors.

Audience Loyalty gives insight into the loyalty and preferences of users in a given competitive landscape, breaking down whether a site's user base visits that site exclusively, or visits multiple sites within a competitive set during a session.

FAQs

  • Why are large sites (like amazon.com, facebook.com, google.com, etc.) not on the Audience Overlap table when looking at a specific country filter?

    For each website and country filter combination on this page, we present the top 1,000 most relevant sites. The most relevant sites will not necessarily be the most overlapping sites, and relevancy acts as a filter to show only interesting results. This is because big sites such as facebook.com, amazon.com, etc. will always have a higher overlap with other sites, and we want to address this bias. For this reason, sometimes big sites you would expect to see in this list are not included in the top 1,000.

    Additionally, for each specific country, users tend to use regional sites for their needs (shopping, price comparisons, etc.). Therefore, when looking at overlapping sites with a specific country filter, you are less likely to see those very big sites, whereas, with the Worldwide country filter, more globally and widely used sites (e.g., amazon.com) are given more weight.

  • What's the difference between the Cross-Browsing Interests table from Audience Interests and the Audience Overlap feature

    The Cross-Browsing Interests table shows the overlap of websites "head-to-head" but doesn’t show the full audience reach and potential. Audience Overlap allows you to compare up to five websites and see the overlap across all websites

  • What time frame is Audience Loyalty based on?

    Audience loyalty is calculated based on monthly unique visitors. So, if a user has visited another site within the same month, they will be counted.

  • Do you support the worldwide country filter?

    Yes.

  • Is only desktop data available?

    Yes.
