Content to Code Ratio
Measure how much of a page is readable text versus markup.
About Content to Code Ratio
Estimating visible text weight from the word count and dividing by total page bytes gives the content share, with the rest counted as markup and scripts. A low ratio hints at a bloated shell around thin text. A page weighed down by markup loads slower and buries its meaning, so a healthy text ratio nudges SEO and user experience in the same direction.
