About the Keyword Density Checker
Keyword density is the percentage of a page's words made up by a given term or phrase — a quick signal of whether content is naturally focused or awkwardly stuffed. This checker analyzes any block of text and ranks the most frequent words and phrases by how often they appear and what share of the content they represent.
Content writers and SEOs use it to audit a draft before publishing: confirming the target topic actually shows up, spotting a phrase that has been repeated too aggressively, or finding the unexpected filler words eating up the count. Because it can analyze two- and three-word phrases, not just single words, it surfaces the multi-word terms that often matter most for search.
How to Use the Keyword Density Checker
- Paste your content into the input box.
- Choose a phrase length — 1, 2, or 3 words — to analyze single keywords or longer phrases.
- Adjust the options: toggle "Exclude stop words", set a minimum word length, and turn case sensitivity on or off.
- Click Analyze to see the ranked table of words or phrases with their counts and density percentages.
- Sort by count, density, or alphabetically, then Copy the results or Export CSV for your records.
Why Use ToolForge’s Keyword Density Checker
- It analyzes one-, two-, and three-word phrases, so you can audit the longer key phrases that single-word counters miss entirely.
- A built-in stop-word filter removes 40-plus common words like "the" and "and" by default, so the ranking reflects meaningful terms — and you can switch it off when you need the raw count.
- Results export to CSV and copy as text, fitting straight into a content audit spreadsheet or a report.
- All analysis happens in your browser, so unpublished drafts are never uploaded.
Frequently Asked Questions
What is a good keyword density?
There is no official target, but most SEO guidance suggests keeping a primary keyword in the low single digits as a percentage — roughly 1–2% — to stay natural. Far higher densities can read as keyword stuffing. Use this tool to spot terms that are over-represented rather than chasing an exact number.
What are stop words and why exclude them?
Stop words are extremely common words such as "the", "and", "is", and "to" that carry little topical meaning. Excluding them — the default here — keeps the ranking focused on words that actually describe your content. You can include them by unchecking the option.
What does phrase length do?
It sets how many consecutive words count as a single term. At length 1 you see individual words; at length 2 or 3 the tool counts two- and three-word phrases, which is how you find meaningful multi-word key phrases instead of isolated words.
Is my content sent anywhere?
No. The text is analyzed entirely in your browser with JavaScript and is never uploaded, so you can safely check drafts and unpublished pages.
