A student once showed me his article about AC repair in Karachi. The phrase AC repair Karachi appeared thirty one times in five hundred words. He thought more mentions meant better ranking. Google thought it looked like spam and the page never ranked. A keyword density checker would have shown the problem in seconds.
What is keyword density
Keyword density is the percentage of words on a page that belong to a specific keyword or phrase. If a 1000 word article uses a two word phrase 10 times, the phrase covers 20 words, which is a density of 2 percent.
Density is not a ranking factor by itself, but it is a great warning signal. Very high density often means keyword stuffing, which can hurt you. Very low density can mean the page is not clearly about the topic.
What the checker shows
Our Keyword Density Checker works with a live page URL or pasted text. It shows three tables:
- Single words with count and density
- Two word phrases which reveal your real focus topics
- Three word phrases which often match your target keywords
Common filler words like the, and, of and for are removed so you only see meaningful terms. Any keyword above 3 percent is highlighted so you can spot stuffing quickly.
How to use it
- Open the Keyword Density Checker.
- Enter a page URL, for example your blog post, or paste your draft text.
- Click Check Density.
- Review the two and three word tables first. They tell you what Google probably thinks the page is about.
What is a good keyword density
There is no magic number, but these ranges work well in practice:
- 0.5 to 2.5 percent for your main keyword phrase
- Below 1 percent for secondary phrases
- Above 3 percent is usually a red flag for a single phrase
More important than the number is how it reads. Read your paragraph out loud. If it sounds robotic, reduce repetition.
How to fix high keyword density
- Replace some exact mentions with synonyms and pronouns.
- Use related terms. Our LSI Keywords Generator finds words people naturally use around your topic.
- Add depth instead of repetition. Explain steps, prices, examples and mistakes.
- Move the keyword to important places such as the title, first paragraph and one heading, then relax elsewhere.
How to fix low keyword density
If your main phrase barely appears, the page may look unfocused. Mention it in the title, the opening lines and at least one subheading. Then check the result with the On-Page SEO Checker, which tests keyword placement across the whole page.
Use it for competitor research
Run the checker on a competitor page that ranks well. The two and three word tables reveal which topics they cover. If they mention warranty, delivery and installments often and you never do, you have found a content gap.
A simple workflow before you publish
Here is the routine I follow for every article. First I write freely without thinking about keywords at all, because the first draft should sound like a person explaining something to a friend. Then I paste the draft into the checker. If my main phrase is missing from the top ten two word phrases, I add it to the title, the introduction and one heading. If it is above three percent, I replace a few mentions with natural alternatives.
Next I look at the three word table. It often shows phrases I repeated by accident, like best price in or click here to. Cleaning those up makes the article read better instantly. Finally I compare my table with a competitor that ranks on page one. Topics that appear in their table but not mine become new paragraphs. This whole check takes less than five minutes and catches problems that would otherwise cost weeks of ranking.
Frequently asked questions
Is keyword density still important for SEO
It is not a direct ranking factor, but extremely high or low density still affects how natural and relevant your page looks.
Can I check a page that is not mine
Yes. Enter any public URL and the tool reads the live page.
Does it count words in menus and footers
It focuses on the main text and ignores scripts and styles, so the numbers reflect the content readers actually see.
