Muck Rack currently partners with SimilarWeb and Comscore to provide unique visitors per month (UVM) for media outlets. If available, the UVM for a media outlet will be displayed directly on its profile page (e.g. http://muckrack.com/nyt).
If SimilarWeb or Comscore isn't tracking a particular media outlet, we will display N/A for UVM to signify that the data isn’t currently available.
Media outlets are automatically updated monthly when any new or additional UVM data is available, so you always have the most up-to-date information we’re able to provide via SimilarWeb and/or Comscore.
