Questions
How is the SEO score calculated?
Weighted questionnaire across 4 categories. Each question has a weight based on real-world importance. Your score is the sum of weights for YES answers divided by total possible weight, expressed 0-100. Letter grade follows standard academic scale.
What is a good SEO score?
An SEO score of 80+ (B- or higher) indicates your page follows most best practices. Scores of 90+ (A- or higher) are excellent. Below 60 (D or lower) indicates significant opportunities. Remember: this reflects on-page factors you can control. External factors like backlinks and competitive landscape also matter.
What is AIO Readiness?
AIO Readiness measures how well your content is optimized for AI Overviews. AIO-ready content uses clear Q&A format, FAQ schema, well-labeled sections, concise factual statements, and signals like llms.txt that help AI systems understand and cite your content.
Why are some questions weighted more than others?
Questions are weighted by real-world SEO impact. HTTPS and mobile responsiveness are weighted at 5 because they directly affect whether Google will rank your page competitively. Title tags and meta descriptions are 3-4. Formatting details carry less weight.
Should I aim for a perfect 100?
Not always necessary. Some questions may not apply to every page. Focus on high-weight questions first. Once above 85, further improvements have diminishing returns. Your time may be better spent creating more optimized content or building backlinks.
Is this tool free?
Yes. No sign-up, no limits, no data collection. All calculations happen in your browser. You can use it as many times as you need.
