CyberCodeKeyword Density Checker
Free keyword density checker. Paste your content to see the most frequent keywords and two-word phrases with counts and density percentages — with stop-word filtering.
What is keyword density?
Keyword density is the percentage of times a word or phrase appears in a text relative to the total word count. If 'dns lookup' appears 12 times in a 600-word article, its density is 2%.
There is no magic density that ranks a page — Google's guidance is to write naturally. The real use of this tool is diagnostic: spotting accidental keyword stuffing (densities above 3–4% read as spammy) and checking that your target phrase actually appears in the copy at all.

Frequently asked questions
- What is the ideal keyword density?
- There isn't one — Google has confirmed there is no target percentage. Under 1% may mean the topic is unclear; above 3–4% starts reading as keyword stuffing. Write naturally and use this tool as a sanity check.
- What are stop words and why filter them?
- Stop words are extremely common words like 'the', 'and', 'of' that carry no topical meaning. Filtering them surfaces the terms that actually describe your content.
- Why does the tool show two-word phrases?
- Most valuable search queries are multi-word. Seeing your top two-word phrases tells you which exact phrases your content emphasises — often more useful than single-word counts.
- Is my content uploaded anywhere?
- No. The analysis runs entirely in your browser — your draft never leaves your device, so it is safe for unpublished content.
