Mobile Ranking Distribution is a histogram of where your mobile organic rankings sit across average-position buckets (for example 1 to 3, 4 to 10, 11 to 20, 21+) for the selected period. It answers “are my mobile rankings clustered near the top of page one, or stranded on page two?” rather than reporting a single average. Because Google indexes mobile-first and mobile is the majority of organic traffic for most ecommerce brands, the mobile shape is the one that matters.
