It is currently only possible to filter by US unique visitors and pageviews. To access the filters you need to be an Advanced subscriber and use these steps:
- Go to Site Screener.
- Run a search.
- In the "Filters Applied" section, click Adjust filters.
- Set the Monthly Pageviews, Monthly Unique Visitors, and Unique Visitor Growth fields to the values you would like to filter based on.
- Press "Apply filter."
Note: The default filters are Countries: US and Languages: English. Since the pageviews and unique visitors filters are only available for US, if you select an option other than US or All Countries the filters will no longer be accessible.
