Mobile Usability

How well a site functions on mobile devices, evaluated by Google as a ranking factor.

Mobile usability covers viewport configuration, tap target spacing, text legibility, content sizing and absence of unplayable content. Issues are flagged in Search Console's Mobile Usability report. With mobile-first indexing, mobile usability problems can suppress entire site rankings, not just mobile results.
