SEO Analysis

LLMSE analyzes websites for SEO optimization and assigns grades from A to F based on technical factors that impact search engine visibility.

SEO Grading System

Every website classified by LLMSE receives an SEO grade based on technical optimization factors:

A Excellent (90-100) — Highly optimized with comprehensive meta tags, proper structure, and best practices
B Good (80-89) — Well-optimized with minor improvements possible
C Average (70-79) — Basic SEO in place but missing important optimizations
D Below Average (60-69) — Significant SEO issues that need attention
F Poor (<60) — Critical SEO problems affecting search visibility

What We Analyze

The SEO grade is calculated based on multiple technical factors:

  • Title Tag — Presence, length, and optimization of the page title
  • Meta Description — Whether a descriptive meta description exists
  • Heading Structure — Proper use of H1-H6 heading hierarchy
  • Image Alt Text — Accessibility and SEO attributes on images
  • Open Graph Tags — Social media sharing optimization
  • Canonical URLs — Proper handling of duplicate content
  • Language Declaration — Proper HTML lang attribute
  • Mobile Viewport — Mobile-friendly configuration
  • Schema Markup — Structured data for rich snippets

SEO Grade in Search Results

When you classify a website through the web interface or browse classified URLs, you'll see the SEO Grade displayed alongside other classification data like category, language, and sentiment.

The grade provides a quick at-a-glance indicator of how well a site is optimized for search engines. This is useful for:

  • Competitive analysis — Compare SEO quality across sites in a category
  • Quality filtering — Find well-optimized sites in specific topics
  • Research — Understand SEO trends across different industries
