Keyword Density Checker (Thai-aware)
Paste your article, landing page or caption and instantly see which words and phrases appear most often, and at what density. Built for SEO writers and marketers working in Thai and English, it segments spaceless Thai text correctly, groups results into 1-, 2- and 3-word phrases, and flags anything that looks over-optimized. Everything runs in your browser and it is completely free.
Comma-separated, up to 10. Matched as exact text, so brand names count correctly even where Thai segmentation misses them.
Stop words are very common words (the, and, ที่, และ) that add noise to frequency counts.
By default numbers and URLs are skipped. Turn this on to count numeric tokens too.
Ignore single-word entries shorter than this (in characters). Applies to 1-word phrases.
Thai word boundaries are dictionary-based and approximate — brand names and slang may split unexpectedly.
Your browser does not support precise Thai segmentation — Thai results are approximate.
