What Is Keyword Density Analysis?
Keyword density analysis measures how frequently a specific word or phrase appears in a piece of content relative to the total word count, expressed as a percentage. A keyword density analyser automates this calculation — paste your content, and the tool reports density for every significant word and phrase in your text.
WordCountNow's Keyword Density Checker analyses your text instantly in the browser and returns density figures for single words, two-word phrases, and three-word phrases, sorted by frequency.
How to Read Your Keyword Density Report
A typical keyword density report lists every word or phrase alongside its frequency count and percentage. Not everything in the list is meaningful. Common words like "the", "and", "is", and "for" will always appear with high frequency — these are stop words, and most tools filter them automatically.
Focus on the content words — nouns, verbs, and phrases that reflect your topic. Your primary target keyword should typically appear at a density of 0.5–2.5%. Below 0.5% may signal the page isn't clearly associated with that keyword. Above 3% risks appearing to search engines as keyword stuffing, which can suppress your rankings.
Ideal Keyword Density by Content Type
- Blog posts (1,000–2,000 words): Primary keyword at 1.0–2.0%
- Landing pages (500–1,000 words): Primary keyword at 1.5–2.5%
- Long-form guides (3,000+ words): Primary keyword at 0.5–1.5%
- Product descriptions: Primary keyword at 1.0–2.0%
- Meta descriptions: Include the keyword once naturally
Using Keyword Density Analysis in Your Workflow
Write your content naturally first, then analyse density afterwards. Checking during writing leads to forced repetition that damages readability. Once your draft is complete, run a density analysis and look for two issues: keywords that are too sparse (add a few natural mentions) and keywords that feel forced (vary your language with synonyms).
Compare your density against the top-ranking pages for your target keyword. If competing pages average 1.2% and your page is at 2.8%, you may be over-optimising. Data from real competitors gives you a target range tailored to your specific niche.
