Deduplicated Audience

A deduplicated audience reveals how many users are driving traffic to a website across devices.

This facilitates more accurate audience analysis and can deliver a clear understanding of where companies should spend their media budget (mobile/desktop/both). Deduplicated audiences can be considered a proxy for a website’s actual user base.


To estimate the size of deduplicated audiences, Similarweb uses a learning set and linear regression modeling to build an algorithm that can estimate the size of a website’s deduplicated monthly visitors.


A high percentage of deduplicated audience can indicate engaged users with high intent and platform stickiness since users are visiting the site from more than one device.

Users can see the deduplicated audiences metric on the following pages:

  • Website Analysis > Traffic & Engagement

  • Website Analysis > Website Performance

Pro Tips: For now, the deduplicated audience metric is not available on a daily or weekly granularity and as such, in the 'last 28 days' time frame, deduplicated audience data won't be available. Also, deduplicated audience data is only available when looking at 'all traffic' so you won't see data for desktop and mobile web separately.

For more information, see Deduplicated Audience.
