❓ FAQ
❓ Do I need to upload data for SEO analysis?
No. All analysis is performed entirely in your browser. Your content is never uploaded to any server, ensuring data privacy and security.
❓ What analysis items are included?
The tool analyzes: title tag length (50-60 chars recommended), meta description length (150-160 chars recommended), H1-H6 heading structure, keyword frequency and density, word count, paragraph count, readability score, image alt text presence, link count, and more.
❓ What is a good keyword density?
Generally, target keyword density of 1%-3% (1-2 times per 100-200 words) is recommended. Higher density may be seen as keyword stuffing, while lower density may not help rankings. The tool automatically calculates density for each keyword.
❓ How long should the title tag be?
Title tags should ideally be 50-60 characters. Longer titles get truncated in search results, while shorter ones may not fully describe the content. The tool highlights title length and provides recommendations.
❓ How should I write meta descriptions?
Meta descriptions should be 150-160 characters, include target keywords, and have a call-to-action. Each page should have a unique, accurate meta description. The tool checks length and keyword inclusion.
❓ Is this tool free?
Yes, completely free. No registration or payment required.
