Website Structural Integrity Scanner

What does the Website Structural Integrity Scanner do?

Most website evaluations focus on performance, keywords, or backlinks.

This tool evaluates something more foundational: structural architecture.

The Website Structural Integrity Scanner is a lightweight diagnostic tool designed to assess how a website is organised beneath the surface. It analyses hierarchy, crawl depth, semantic structure, content distribution, and internal linking patterns within a controlled sample of pages.

Rather than measuring traffic signals or ranking factors, it focuses on architectural coherence, how consistently and logically a site is built.

The goal is clarity.

Clear structure improves usability, maintainability, and content alignment. Structural integrity supports long-term growth by ensuring pages are proportionally developed and hierarchically organised.

This tool provides a structured snapshot of architectural conditions within your website design.

Built In-House

This scanner is custom-developed and does not rely on third-party SEO audit APIs.
It performs a controlled structural crawl using server-rendered HTML and evaluates architectural patterns based on internal hierarchy, depth distribution, and content variance models.

Scanner available to administrators only.

Understanding Your Structural Integrity Report

The Website Structural Integrity Scanner evaluates how your website is organised beneath the surface.

It focuses on structural architecture rather than design, backlinks, or keyword strategy, other related SEO metrics .

Below is a breakdown of what each section means and how to interpret your results.

Overall Structural Score

The overall score (0–100) reflects a weighted combination of:

  • Heading integrity

  • Semantic landmark usage

  • Content depth balance

  • Internal link health

  • CTA clarity

  • Structural consistency

It provides a high-level indicator of how coherent and balanced your website architecture is within the sampled pages.

This score is comparative, not absolute. It evaluates structure within your site rather than comparing you to external competitors.

Crawl Depth Distribution

Crawl depth measures how many clicks a page is from the homepage.

  • Depth 0: Homepage

  • Depth 1: Pages directly linked from the homepage

  • Depth 2+: Pages nested further inside the structure

Why it matters:

Crawl depth influences how easily users and search systems can reach content.

Very flat structures may limit content layering.
Very deep structures may isolate important pages.

A balanced structure typically places core services within one or two clicks of the homepage.

Structural Consistency Index

The Structural Consistency Index evaluates how evenly your website is built across pages.

It measures:

  • Variation in word counts

  • Variation in heading distribution

  • Structural deviation across sampled pages

Large disparities can indicate uneven development or organic growth without architectural standardisation.

Consistency does not mean identical pages.
It means maintaining proportional structure and hierarchy as your site grows.

Semantic Density Ratio

Semantic density reflects the relationship between headings and content body length.

It is calculated using the ratio of structural headings (H2–H4) to total word count.

Lower density may indicate large blocks of unstructured content.
Higher density may indicate excessive segmentation or overuse of headings.

Balanced semantic density supports readability and improves structural clarity.

Internal Link Health

Internal links connect pages within your website.

This section evaluates:

  • Pages with low inbound internal links

  • Pages that are structurally isolated within the scanned sample

Internal linking influences how information flows through a website.
Well-connected pages are generally easier to discover and reinforce each other’s context.

Severity Levels Explained

Issues are categorised by severity to help prioritise improvements:

  • Critical – Structural problems affecting large portions of the site

  • Structural Risk – Issues that may impact clarity or coherence

  • Moderate – Areas that could benefit from refinement

  • Minor – Smaller inconsistencies

Severity does not necessarily indicate search penalties.
It highlights structural conditions observed within the scanned pages.

Common Structural Patterns Observed

Across many websites, the following patterns are frequently identified:

  • Inconsistent heading hierarchies

  • Uneven content investment across core pages

  • Heavy reliance on homepage navigation

  • Limited cross-linking between service pages

  • Absence of semantic landmarks such as <main>

These patterns often emerge gradually as websites expand.

Frequently Asked Questions

What is structural consistency?

Structural consistency refers to how proportionally and coherently pages are developed across a website.

It considers content depth, heading hierarchy, and distribution balance rather than visual design.

What is crawl depth?

Crawl depth measures how far a page sits from the homepage in terms of click distance.

Pages positioned deeper in a structure may require additional internal linking to maintain accessibility.

What is semantic density?

Semantic density is the ratio between structural headings and content length.

It provides an indication of how well content is segmented and organised hierarchically.

Does this replace an SEO audit?

No.

This tool focuses exclusively on structural architecture.

It does not evaluate keyword targeting, backlinks, schema, page speed metrics, or competitive positioning.

Structural integrity is one component of broader digital performance.

Limitations of the Tool

The Website Structural Integrity Scanner is designed as a lightweight architectural diagnostic tool. It evaluates structural characteristics within a controlled crawl sample and does not provide a complete technical or SEO audit.

Below are the key limitations:

1. Limited Crawl Scope

The scanner analyzes a restricted number of pages within a defined depth range. It does not crawl an entire website.

Results reflect patterns observed within the sampled pages and may not represent every page on larger websites.

2. No Performance or Speed Metrics

This tool does not measure:

  • Page load speed

  • Core Web Vitals

  • JavaScript execution performance

  • Hosting infrastructure

Structural integrity is evaluated independently of performance benchmarks. You can use our Free SEO Audit Tool for that.

3. No Keyword or Ranking Analysis

The scanner does not evaluate:

  • Keyword targeting

  • Search rankings

  • Backlink profiles

  • Competitive positioning

It focuses exclusively on structural architecture and internal organisation.

4. No Content Quality Assessment

Word counts and semantic density are measured structurally.

The tool does not evaluate:

  • Writing quality

  • Topical accuracy

  • User intent alignment

  • Conversion effectiveness

Structural balance does not automatically indicate content effectiveness.

5. Dynamic or Script-Rendered Content

The scanner relies on server-rendered HTML responses.

Websites that heavily depend on client-side rendering or JavaScript-driven content may show incomplete structural data.

6. Interpretive Indicators, Not Penalties

Severity labels such as “Moderate” or “Structural Risk” describe observed architectural conditions.

They do not indicate search engine penalties or guaranteed performance outcomes.
