How the SEO Scan Works

The SEO scan (1,500 credits) performs a comprehensive technical and on-page SEO audit across 8 dimensions. It goes far beyond basic meta tag checks — it measures Core Web Vitals, crawlability, schema markup, internal link structure, image optimization, and trust signals.

The 8 SEO Dimensions

1. Technical SEO

Crawlability and indexability checks:

• robots.txt existence and correctness
• Sitemap.xml existence and validity
• Canonical tags
• Noindex/nofollow directives
• HTTP to HTTPS redirect enforcement
• Page status codes (404s, redirect chains)
• Mobile viewport meta tag

2. Content Analysis

On-page content quality signals:

• Title tag presence, length (50-60 chars ideal), and uniqueness
• Meta description presence and length (120-160 chars ideal)
• H1 tag presence and uniqueness
• Content length (thin content detection)
• Keyword density (over-optimization signals)
• Structured heading hierarchy (H1 → H2 → H3)

3. Link Analysis

Internal and external link structure:

• Internal link count and distribution
• External link count and follow/nofollow ratio
• Broken link detection
• Link anchor text diversity
• Orphaned pages (no internal links pointing to them)

4. Image Optimization

Visual content SEO:

• Alt text presence on all images
• Image file size (oversized images flag as performance issues)
• Image dimensions declared in HTML
• Descriptive filename patterns

5. Performance (Core Web Vitals)

Google uses these as ranking signals:

• LCP (Largest Contentful Paint) — how fast the main content loads. Good: under 2.5s
• CLS (Cumulative Layout Shift) — how much the page visually shifts while loading. Good: under 0.1
• FCP (First Contentful Paint) — time to first visible content
• TTFB (Time to First Byte) — server response time
• Page size and request count

6. Schema Markup

Structured data for rich search results:

• JSON-LD, Microdata, or RDFa presence
• Schema types detected (Organization, WebSite, Product, Article, FAQ, etc.)
• Validation against schema.org specifications
• Rich snippet eligibility

7. Sitemap

XML sitemap health:

• Sitemap discovery via robots.txt and /sitemap.xml
• URL count and format validity
• Presence of lastmod dates
• Image sitemap entries

8. Trust Signals

Domain authority and credibility indicators:

• Domain age (older = more trusted)
• HTTPS enforcement
• Privacy policy page detection
• Contact page detection
• Social media presence links

How the Score Is Calculated

Each dimension contributes a weighted sub-score. The overall SEO score is a composite from 0-100:

Score	Meaning
90-100	Excellent
70-89	Good — minor improvements available
50-69	Fair — several issues affecting ranking potential
Below 50	Poor — significant technical issues
