SEO analysis for Thai websites — Thai word count, keyword density, Schema, hreflang, OG preview, and more.

SEO analysis built for Thai websites — ตัดคำไทย นับคำ ตรวจ Schema hreflang และอื่นๆ The only SEO extension that truly understands Thai. Accurate word counts, keyword density, readability scoring, and 20+ checks — all running locally in your browser. No account needed. No data sent anywhere. Why existing SEO extensions fail on Thai sites Global tools like Detailed SEO, Ahrefs Toolbar, and MozBar split text on whitespace. Thai has no spaces between words. The result? A 500-word Thai article shows as “5 words.” Keyword density is broken. Readability scores are meaningless. SEO Toolkit fixes this by using Chrome's native Thai word segmentation — the same technology that powers Google Search. Changelogs: https://nutttaro.com/extension/seo-toolkit#changelog
