Keyword Density Checker

Keyword density represents the percentage of times a specific keyword or search phrase appears within a webpage’s total word count. Search engine crawlers (like Googlebot) use this metric to comprehend the primary subject of your document. Maintaining balanced keyword density ensures search engines index your content correctly without penalty.

Most SEO professionals and industry studies recommend a keyword density between 1% and 2.5%. This means your target keyword appears 1 to 2 times every 100 words. Anything above 3.5% risks triggering Google’s algorithmic spam filters for keyword stuffing.

Keyword stuffing is the practice of loading a webpage with keywords in an attempt to manipulate search engine rankings. Our tool automatically highlights phrases exceeding 3.0% density with an amber or red warning badge so you can naturally rephrase your sentences before publishing.

Yes! Modern search queries are predominantly long-tail (multi-word phrases). Our analyzer allows you to switch between 1-Word (unigrams), 2-Word (bigrams), and 3-Word (trigrams) to inspect long-tail keyword distributions with precision.

Stop words are commonly used grammatical words such as "the", "in", "is", "at", "which", and "on". While essential for grammar, they skew SEO calculations. Filtering stop words lets you see your actual topic keywords rather than common conversational particles.
