Keyword Density Analyzer

Check the keyword density, word frequency, and phrase patterns in any piece of content. Paste an article, blog post, or product description and instantly see which words and phrases appear most often, whether your target keyword sits in a healthy range, and where you might be over-repeating. Everything runs in your browser — nothing is stored or sent anywhere.

What is the ideal keyword density for SEO?

Most SEO professionals recommend keeping your primary keyword density between 1% and 3%. This range tells search engines your page is relevant to a topic without crossing into over-optimization territory. The exact sweet spot depends on content length, competition, and how naturally the keyword fits your writing. Longer articles naturally spread keywords more evenly, so a 2,000-word post at 1.5% density is perfectly healthy. Short pages might land slightly higher and still read fine. The key is that density should be a check after writing, not a target you write toward.

How do I use keyword density data for SEO best practices?

Start by identifying your primary keyword and two or three secondary keywords. Write your content naturally first, focusing on being helpful and thorough. Then run it through this analyzer. Check that your primary keyword sits between 1-3%, secondary keywords appear at least a few times, and no single word or phrase dominates unnaturally. Review the bigrams and trigrams — repeated two and three-word phrases often reveal your content's true topical focus and can highlight unintentional repetition you missed while writing. Use the data to make small edits, not to rewrite from scratch.

What is keyword stuffing and how do I avoid it?

Keyword stuffing means cramming a keyword into your content an unnatural number of times to try to manipulate search rankings. Google has penalized this practice for years. Common signs include density above 5%, awkward phrasing where keywords feel forced into every sentence, and the same phrase appearing in nearly every paragraph. To avoid it, write for humans first, use synonyms and related terms throughout your content, and check your density after writing rather than before. If a keyword appears more than once every 50-100 words, it is likely overdone. This tool color-codes your target keyword density to make the check instant — green means healthy, yellow means borderline, red means you should edit.
