What title pixel budgets does the preview use?

Desktop titles are modeled as a single Arial ~20px line of about 600px. Mobile titles use a two-line clamp of about 805px.

How does the URL line differ on desktop and mobile?

Since January 2025, mobile shows favicon and domain only. Desktop still shows site name › path.

Which rich results can I preview?

Only live types: review stars (AggregateRating), product price and stock, byline dates, and desktop breadcrumbs. FAQ rich results were removed on May 7, 2026.

Will Google show my exact title?

Not always. Google rewrites about 62% of titles. The simulator shows your input against current pixel budgets; it does not predict rewrites.

What do the meters and diagnostics show?

Pixel usage for title and description on desktop and mobile, plus notes on URL format and which rich results are still live.
