The **SEO Audit Engine** runs 50+ automated checks on every crawled page, producing a **0-100 score** with letter grades and actionable fix suggestions. Audits run automatically during crawling and can be re-run on demand at no cost.

## How Audits Work

Audits are triggered in two ways:

1. **During crawl** - when the [Edge Crawler](/docs/edge-crawler) indexes a page, the audit engine automatically analyzes the stored HTML. No extra credits are consumed beyond the crawl cost.
2. **On-demand re-audit** - from the [URL Detail](/docs/pages-overview) page, click **Re-audit** to re-run checks against the currently stored HTML. This is **free** - useful after making rule changes that affect the page output.

The audit engine parses the stored HTML snapshot and evaluates each check against SEO best practices. Results are stored and displayed on the **SEO Audit** tab of the URL Detail page.

## Scoring System

Each page receives a score from **0 to 100**, mapped to letter grades:

| Score  | Grade | Meaning                                            |
|--------|-------|----------------------------------------------------|
| 90-100 | **A** | Excellent - meets or exceeds SEO best practices    |
| 80-89  | **B** | Good - minor improvements possible                 |
| 70-79  | **C** | Fair - several issues should be addressed          |
| 60-69  | **D** | Poor - significant issues impacting SEO            |
| 0-59   | **F** | Critical - major problems need immediate attention |

The overall score is a weighted sum across audit categories.

## Audit Categories

Checks are grouped into 9 categories, each with a defined weight in the overall score:

| Category          | Weight | What It Checks                                                         |
|-------------------|--------|------------------------------------------------------------------------|
| **Meta Tags**     | 20%    | Title length, description length, presence, duplication, keyword usage |
| **Open Graph**    | 10%    | OG title, description, image, type, URL                                |
| **Twitter Cards** | 5%     | Twitter card type, title, description, image                           |
| **Headings**      | 15%    | H1 presence and count, heading hierarchy, keyword usage in headings    |
| **Content**       | 15%    | Word count, thin content, reading level, content-to-HTML ratio         |
| **Images**        | 10%    | Alt text presence, image dimensions, lazy loading, file sizes          |
| **Links**         | 10%    | Internal link count, broken links, nofollow usage, orphan detection    |
| **Schema**        | 10%    | JSON-LD presence, schema types, required properties, validation        |

## Category Breakdown View

The SEO Audit tab displays each category as an expandable card. Click a category to see its individual checks:

- **Pass** - check passed successfully
- **Warning** - non-critical issue that could be improved
- **Error** - critical issue that should be fixed

Each check shows its **impact level** (high, medium, or low) and a brief explanation of why it matters and how to fix it.

* * *

## Issues Panel

Below the category breakdown, the **Issues** panel presents a flat list of all warnings and errors across categories. Use this for a prioritized fix list:

- Filter by **severity** (errors only, warnings only, or all)
- Filter by **impact level** (high, medium, low)
- Each issue links back to its category for context

* * *

## Fix Actions

Many audit issues include a suggested fix action. Issues with auto-fixable strategies show a **Fix with AI** button directly in the audit results - see the [Fix with AI](/docs/fix-with-ai) docs for the full guide.

| Action                               | What It Does                                                                                                                                                                                |
|--------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [**Fix with AI**](/docs/fix-with-ai) | One-click fix - automatically generates a rule (for structural issues like OG tags, canonical, viewport) or triggers [AI Meta Generation](/docs/ai-meta) (for title and description issues) |
| **Manual**                           | Requires changes on your origin server - the audit explains what to change                                                                                                                  |
