Focusing on online publications, AllSides rates sources on a five-point scale. Each source is ranked by unpaid volunteer editors, overseen by two staff members holding political biases different from each other. These crowd-sourced reviews are augmented by editorial reviews performed by staff members. Reassessments may be made based on like button results from crowd-sourced community feedback. AllSides uses these rankings to produce media bias charts listing popular sources. As of 2026, AllSides provides media bias ratings for over 1,400 media outlets and writers.
