Keyword Density Checker

The Keyword Density Checker scans your text and counts how often each word or phrase appears. It then compares these counts to the total word count to show keyword percentages. You’ll also see reports of which single words or phrases appear most often. It’s a quick way to understand how search-friendly and balanced your content is.

Stop words are very common words like “the”, “and”, “of”, or “in” that usually don’t carry much meaning on their own. When you exclude stop words, the checker focuses on the more important terms in your text, like product names, topics, and key phrases. This makes your keyword reports cleaner and easier to read. If you want to see the raw, full picture of every word used, you can turn stop word filtering off.

Keyword density helps search engines figure out what your page is about. Keeping a healthy balance makes your content relevant for specific searches without looking spammy. It’s a key factor in showing search engines you’re covering a topic naturally and in depth.

Aim for roughly 1–2% for your main keywords. Don’t obsess over exact numbers — the goal is to sound natural and helpful. Anything much higher than 3% might look forced or spammy to search engines. Write for readers first and use your keywords where they make sense.

Yes. You can use it for short blog posts or full-length articles, guides, and ebooks. The tool handles any text size and gives you detailed keyword breakdowns no matter how long your content is.

Keyword stuffing means cramming too many keywords into a page in an unnatural way. It can hurt both rankings and readability. To avoid it, write naturally, mix in synonyms, and make sure your text flows well. Keeping keyword usage below 3% usually keeps you safe.

Yes — it’s a good habit for all major pages: blogs, product pages, landing pages, and services. Each should focus on its own keywords at a healthy level. Regular checks help you find pages that need more balance or better targeting.

Look at the top keywords and their percentages. Ideally, your main keywords appear around 1–2%, and related terms are spread naturally. Over 3% means you might be overdoing it; below 0.5% could mean the topic isn’t clear enough. The best content feels natural but still focused.

Definitely. You can paste in a competitor’s text to see what keywords they focus on, how often they use them, and which topics they emphasize. It’s a great way to spot opportunities or areas where your content could outperform theirs.

Voice search likes natural, conversational language. Focus more on question-style phrases and longer, human-like wording instead of short, exact keywords. A slightly lower keyword density with varied phrasing performs better for voice-based results.

Keyword density measures how often a word appears compared to the total number of words. TF-IDF goes further — it compares how often that word appears in your text versus how common it is across the web. Density gives a basic view; TF-IDF shows how important a keyword really is in context.

Use both. Single words help cover broad topics, while longer keyword phrases (three to five words) attract more specific searches and conversions. The checker analyzes both types so you can fine-tune your balance.

LSI (Latent Semantic Indexing) keywords are words and phrases related to your main topic. Using them helps search engines understand context. Instead of repeating one keyword, mix in similar terms and related concepts to build richer, more natural content.

Yes. They highlight where you might be repeating too much or missing key terms. That makes it easier to keep your writing clear, natural, and focused. Just remember: the tool supports good writing — it doesn’t replace it.

It’s smart to check whenever you publish new content, update old pages, or review SEO performance. Many editors also recheck density after big algorithm updates. A quick quarterly review of your key pages keeps your site healthy and well-optimized.
