Each row is a category, each column its own count bucket (few on the left, many on the right); the cell is the share of those sites passing CLS.

No category moves the CLS pass rate much, however many a site ships. computed

Per category: the pass rate among pages with FEW of it (hollow ring) against pages with MANY (solid dot), worst trend first. Thin buckets are excluded from the endpoints.

Why this matters for the Core Web Vitals, and where to start fixing it

Where fonts come from decides how many connections sit on the render path. Google Fonts costs two extra domains: one serves the CSS, another serves the font files. Both need DNS, TCP and TLS before text can settle. Self-hosted fonts ride the connection that is already open and follow your cache rules.

The old argument for the shared Google cache is dead: browsers partition their caches per site, so nobody arrives with your font already cached. Self-hosting is strictly better, and it is a one-time move.

How does this affect the Core Web Vitals?

Font source correlates with the LCP. With Third party, 84% of sites pass the LCP. With Google, 78% do.
