About this tool
This is a purely informational technical metric — a low ratio simply reflects how much markup, scripting, or styling a page uses relative to its visible text, and is not, by itself, evidence of an SEO problem.
Frequently Asked Questions
- What is a code-to-text ratio?
- The proportion of a page's HTML that is visible text versus markup, scripts, and styling.
- Does a low ratio hurt SEO?
- Not by itself — modern sites routinely use more markup than older static pages without any ranking penalty.
- How is this calculated?
- By comparing the raw HTML byte size to the extracted visible-text byte size of the fetched page.
