What does this SEO content analyzer check

This tool evaluates your content across six categories: content length, heading structure, keyword usage, readability, formatting, and SEO signals. Each category is scored 0 to 100 and weighted to produce an overall content score. The checks are based on real ranking signals backed by SEO research, not arbitrary rules. You get specific, actionable recommendations for every category so you know exactly what to fix before publishing.

How content scoring works

Your text is analyzed across six weighted categories. Here is how each one contributes to your overall score.

• Content Length (15%) - A Backlinko study of 11.8 million search results found that the average first-page result is 1,447 words. The sweet spot for competitive queries is 1,500 to 2,500 words. Content under 300 words rarely ranks for informational searches, while content over 4,000 words sees diminishing returns unless the topic demands that depth.
• Heading Structure (20%) - Proper H1, H2, and H3 hierarchy helps both users and search engines understand your content. The tool checks for a main heading, multiple subheadings, and whether your focus keyword appears in headings. Pages with clear heading structure earn more featured snippets and perform better in voice search.
• Keyword Usage (25%) - Your focus keyword should appear naturally in the first paragraph, in headings, and throughout the content at 0.5 to 2.5% density. The tool checks for placement in the introduction, conclusion, and overall distribution. Over-optimization (density above 2.5%) can trigger spam filters.
• Readability (15%) - Flesch Reading Ease of 60 to 70 matches the reading level of most web users. Content that is too complex (below 40) loses readers. Content that is too simple (above 90) may lack the depth needed to demonstrate expertise. This score uses the standard Flesch formula based on sentence length and syllable count.
• Structure & Formatting (15%) - Short paragraphs, bullet lists, and text formatting (bold, italics) improve engagement and time on page. Walls of text drive readers away. The tool checks paragraph length, list usage, emphasis markers, and section organization.
• SEO Signals (10%) - Internal links, external references, statistics, sentence variety, and comprehensive subtopic coverage all contribute to ranking potential. The tool checks for citations, data points, link presence, topical depth, and a strong conclusion.

What is a good content score

• 80-100 (Excellent) - Content is well-optimized and ready to compete for page 1 rankings. According to Clearscope data, content scoring 80+ on optimization tools ranks on page 1 at 3x the rate of unoptimized content. On-page fundamentals are strong across all categories.
• 60-79 (Good) - Solid foundation with room for improvement in specific areas. Review the category breakdowns and focus on the lowest-scoring sections.
• 40-59 (Needs Work) - Significant gaps in optimization that will limit ranking potential. Multiple categories need attention before this content can compete in search.
• 0-39 (Poor) - Content needs substantial revision before it can compete. Start with the highest-weighted categories (Keyword Usage, Heading Structure) and work down.

How to improve your content score

Read each category's recommendations and address the lowest-scoring areas first. The biggest impact usually comes from heading structure and keyword usage improvements, since those categories carry the most weight (20% and 25% respectively).

Do not over-optimize. Write for readers first, then adjust for search engines. Keyword stuffing, unnatural heading placement, and forced formatting hurt the reading experience and can trigger search engine penalties. A score of 80+ with natural, readable content is better than a forced 95 that reads like it was written for a bot.

Compare your score with the top 3 ranking pages for your target keyword. If they score lower but rank higher, the gap is likely in off-page factors like domain authority and backlinks. If they score higher, focus on matching their on-page quality first.
