SEO Content Analyzer

Evaluate your content for SEO best practices. Checks readability, keyword density, content length, and structure to help optimize for search engines.

How It Works

This tool evaluates your content against common SEO best practices using several metrics:

• Content length — Checks whether your content meets recommended word counts for search engine indexing (300+ words minimum, 1000+ for thorough coverage).
• Readability — Computes the Flesch Reading Ease score based on average sentence length and syllable count. Scores between 60-70 are ideal for general web content.
• Keyword density — Measures how often your target keyword appears as a percentage of total words. Optimal range is 1-3%.
• Title and meta description — Validates character length against search engine display limits (title: 50-60 chars, description: 120-160 chars).
• Keyword placement — Checks if your target keyword appears in the title, meta description, and opening paragraph.
