# Extraction Noise Ratio

**TL;DR:**Extraction Noise Ratio is how much of what a bot extracts is template noise instead of main content. High noise reduces retrieval quality and increases mis-citations.

## What is Extraction Noise Ratio?

Extraction Noise Ratio is the share of a page’s extractable text taken up by:

- Repeated CTAs
- Navigation, related posts, sidebars
- Footers, legal blocks
- Popups and injected UI
- Generic brand slogans repeated on every page

AIs do not “see” your layout the way humans do. If the DOM is noisy, you pay a visibility tax.

## How Extraction Noise Ratio is Measured

At a basic level: compare the word count of main content vs. non-content.

| Component | How to identify | What to do |
| --- | --- | --- |
| Main content | container, article body | Keep clean and consistent |
| Boilerplate | header/footer, repeated modules | Reduce repetition and verbosity |
| Injected UI | popups, sticky bars | Avoid inserting inside article DOM |**Simple formula:**Noise Ratio = Boilerplate words / (Boilerplate + Main content words)

## Why Extraction Noise Ratio Matters

Noise does not just reduce selection. It increases failure modes:

- AI quotes your CTA instead of your definition
- AI misses the one table that mattered
- AI extracts a partial chunk that loses context

| Page type | Common risk | Typical fix |
| --- | --- | --- |
| Blog templates | repeated modules between sections | simplify layout inside main |
| Product pages | heavy UI, minimal text | add a “facts” section with clean HTML |
| Comparison pages | interactive tables only | provide static HTML table fallback |

## How to Reduce Extraction Noise Ratio

1.**Use a real main container.**Keep the content in one predictable region.
2.**Stop repeating sales blocks mid-article.**Put them after the key extractable sections.
3.**Provide static table fallbacks.**Especially if you use JS rendering.
4.**Standardize your glossary template.**Same DOM pattern every time.

## Extraction Noise Ratio FAQs**Is this just an SEO “content-to-code ratio” rebrand?**Related, but not the same. This is about what extractors pull, not how Google indexes HTML.**Can I keep CTAs?**Yes. Place them where they will not pollute the definition and key findings.
