Why this dimension exists
Title, description and canonical control what a search or answer surface can show about the page.
Why it carries 7%
Moderate, and cheap to satisfy.
The rules it is scored by
Each rule is a single question the scanner asks about a page. Passing one adds its share of this dimension; failing it takes that share away. Every rule links to what it looks for and what evidence passes it.
- <title> is between 15 and 65 characters long.3.0%
- The meta description is between 50 and 160 characters long.2.0%
- At least one meta property beginning with og: is present.1.0%
- The <html> element carries a lang attribute.1.0%
What this dimension cannot tell you
A single-URL scan reads one page. It cannot see the rest of the site, it cannot see how a model behaves over time, and it cannot see whether the page is actually cited for the queries that matter. Those are the parts of the picture a score of this kind is blind to, and they are listed in full on the methodology page rather than implied here.
