Thai SEO title and meta checker
Preview Thai search copy and catch encoding, language and repetition problems in your browser. No signup and no URL fetching.
Four worked checks
Every row is computed by the same function as the tool. Word counts use Node 22 ICU Thai word segmentation.
| Example | UTF 16 | Graphemes | Words | Findings |
|---|---|---|---|---|
| A. Clean Thai title | 32 | 25 | 7 | No problems found |
| B. Decomposed sara am and repeated words | 49 | 38 | 10 | Decomposed sara am: fix, Repeated words: check |
| C. English title on a Thai page | 29 | 29 | 4 | Language mismatch: check |
| D. Hidden zero width space | 18 | 11 | 6 | Invisible characters: fix |
Width findings are absent because the Google evidence capture hit a CAPTCHA.
Google guidance, rules and limits
Google title link guidance, checked 30 October 2026: “While there's no limit on how long a <title> element can be, the title link is truncated in Google Search results as needed, typically to fit the device width.”
Google snippet guidance, checked 30 October 2026: “There's no limit on how long a meta description can be, but the snippet is truncated in Google Search results as needed, typically to fit the device width.”

- There is no fixed character limit claim. Google may rewrite the title link or snippet, and display varies by device and query.
- The live SERP measurement stopped at a CAPTCHA. No truncation verdict or Google preview width is included.
- Pixel widths are measured locally with your browser's Thai fallback font. They are not a prediction of another device's rendering.
Every rule the checker uses
- DLVX Unicode check: write sara am as U+0E33, not U+0E4D followed by U+0E32.
- DLVX text check: remove zero width characters, byte order marks and soft hyphens from search copy.
- DLVX editorial check: remove leading, trailing and repeated spaces.
- Google title link guidance: Google tries to match the page's primary language and writing system, and may rewrite a mismatched title link.
- Google says to avoid keyword stuffing. Three repetitions is a DLVX review threshold, not a Google number.
- Google snippet guidance: Google may create a snippet from page content when no meta description is available.
Google also advises against keyword stuffing. It tries to show a title link that matches the page's primary language and writing system, and may generate a different title link after detecting a mismatch.
