What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears in your content relative to the total word count. The formula is simple: (number of times the keyword appears ÷ total words) × 100. So a keyword used 6 times in a 600-word article has a density of 1%. It is one of the oldest on-page SEO signals, and while search engines are far more sophisticated today, density is still a useful guardrail for spotting both the under-use and the over-use of your target terms.
What is a good keyword density for SEO?
There is no official perfect number, but most SEO professionals aim for roughly 1–2% for a primary keyword. The goal is not to hit a magic figure — it is to mention your topic naturally enough that search engines understand the page, without repeating it so often that it reads like spam.
- Under 0.5% — your keyword may be too sparse and the page focus can look unclear.
- 1–2% — a healthy, natural range for most content.
- Over 3–4% — risk of keyword stuffing, which can trigger ranking suppression.
How to use this keyword density analyzer
- Paste your text into the box, or switch to the Analyze URL tab and enter a page address to pull its content automatically.
- Choose a minimum word length and whether to exclude common stop words such as the, and, and for.
- Click Analyze Content.
- Review the table of top keywords, their counts and density percentages — plus the automated recommendations that flag over-optimization or thin content.
How to fix keyword stuffing
If the tool flags a term above about 3–4%, do not simply delete every instance — rewrite. Swap some mentions for synonyms and related phrases (semantic variation), break the content into clearer sections, and add genuinely useful detail so the keyword share naturally drops. Modern search engines reward topical depth, not exact-match repetition.
Why keyword density still matters in 2026
Google now relies heavily on semantic understanding, entities and search intent rather than raw keyword counts. So why check density at all? Because it is a fast diagnostic: it instantly reveals if you have accidentally over-stuffed a term, ignored your main topic, or written content that is too thin to rank. Treat density as a sanity check that supports good writing — not a target to game.
Who uses a keyword density analyzer
Bloggers editing a draft
You have rewritten an intro four times and the main phrase has crept into every paragraph. A quick density check before publishing catches the repetition your eyes stopped noticing, and the stop-word filter keeps "the" and "and" out of the way.
SEOs auditing old pages
Older posts written for 2015-era SEO often repeat an exact-match phrase at 4% or more. Running them through the analyzer gives you a fast list of pages that read as stuffed and are worth a light rewrite.
Writers checking briefs
When a client asks for a keyword "at least five times", the tool shows whether you hit it and whether the page still reads naturally. It turns a vague instruction into a number you can show them.
Comparing against competitors
Analyse the top three ranking pages for your query and look at which secondary terms they use that you do not. That gap is usually more useful than the density of your main keyword.
Editors of AI-assisted drafts
AI writing tools tend to repeat the prompt's key phrase and a few favourite words. The frequency table makes those tics obvious so you can vary the wording before a human reader or a search engine notices.
Google lists keyword stuffing as a spam practice in its Search Essentials spam policies, but it has never published an ideal density. The ranges above are working rules from editors, not Google figures.
A worked example: reading the numbers
Say you paste in an 1,200-word guide targeting "meal prep containers". The table shows the full phrase 19 times, which is a density of about 1.6%. That looks fine on its own. But the single word "containers" appears 41 times, or 3.4%, and "meal prep" appears 33 times. Read the page aloud and you will hear the problem: nearly every sentence ends on the same noun.
The fix is not to delete mentions until the number drops. Look at what the sentences are actually doing. Where you are describing material, say "glass" or "BPA-free plastic". Where you are describing use, say "lunch boxes" or "portions". Where the noun is obvious from context, use "they". After that edit, the main phrase might sit at 1.2% and the single word at 2%, and the page will read better without losing any meaning. That is the pattern to follow: use the analyzer to find the repetition, then fix it by writing more precisely, not by counting.
Density versus topic coverage
Here is the honest limit of this tool. Keyword density measures repetition, and repetition is a weak signal. Google's systems work out what a page is about from the whole vocabulary on it, the entities it mentions and how well it answers the query. A page about meal prep that never mentions freezing, portion sizes or reheating is thin, however perfect its density is.
So use density as a guardrail, not a goal. It is very good at catching two mistakes: stuffing, where one phrase dominates, and drift, where you have written 1,500 words and mentioned your actual topic twice. Between those extremes, the number matters far less than whether the page covers what a searcher needs. If you want to find out which queries a page is close to ranking for, the Striking Distance Analyzer will tell you more than any density figure. And before you publish, check the title in the SERP Snippet Preview, because the snippet decides whether anyone clicks.
Common mistakes when checking density
- Counting the navigation and footer. If you analyse a live URL, menus, sidebars and footers are included. Paste only the article body when you want an accurate figure for your writing.
- Chasing an exact percentage. There is no reward for hitting 1.5% exactly. Aim for the range, then stop thinking about it.
- Ignoring variants. "Container", "containers" and "container's" are counted separately. Look at the whole family of words before deciding a term is under-used.
- Checking only the main keyword. The more useful view is the list of supporting terms underneath it. If your competitors all mention a concept you never do, add a section about it.
- Analysing very short text. On a 150-word product description, one extra mention moves density by almost a whole percentage point. The numbers only become meaningful from a few hundred words up.
Frequently asked questions
Is this keyword density checker free?
Yes, it is completely free with no sign-up. You can analyze unlimited text or URLs right in your browser.
Does keyword density affect Google rankings?
Indirectly. There is no exact density Google rewards, but stuffing can hurt you and too-thin usage can leave your topic unclear. Natural, well-structured content wins.
What is the ideal keyword density?
Aim for about 1–2% for your main keyword, with related terms and synonyms spread naturally throughout the page.
Can I analyze a competitor page?
Yes. Use the Analyze URL tab to fetch and analyze the content of any public web page.
How is keyword density calculated for phrases?
For a multi-word phrase, the tool counts how many times the exact phrase appears and divides by the total word count, then multiplies by 100. Some tools divide by total words minus the extra words in the phrase, which gives a slightly higher figure. The difference is small, so focus on the range rather than the decimal. A phrase that appears far more often than any related wording is the real warning sign.
Should I exclude stop words?
Usually yes. Words such as the, and, of and for are the most frequent words in almost any English text, so they crowd the top of the table without telling you anything. Excluding them shows the terms that actually describe your topic. Turn the filter off only when you are checking a phrase that contains a stop word, such as "how to" or "best of", and want an exact count.
Does it work for languages other than English?
It counts words in any language that separates words with spaces, so French, Spanish, German and similar languages work well. The stop-word list is English, so in other languages switch the filter off or ignore common function words in the results. Languages written without spaces between words, such as Chinese or Japanese, are not split correctly by this kind of counter and need a dedicated tool.
Is keyword density the same as TF-IDF?
No. Keyword density only measures how often a word appears on your page. TF-IDF also compares that frequency with how common the word is across many documents, so it highlights words that are distinctive for your topic. TF-IDF tools are better for finding missing supporting terms. Density is better for a quick check that you have not repeated one phrase too often. They answer different questions and work well together.
How often should I check keyword density?
Check once before publishing and again whenever you make a large edit, such as adding a section or merging two posts. Re-checking every week is unnecessary because the text does not change on its own. It is more useful to audit older posts once a year, because pages written several years ago are the most likely to contain the heavy repetition that older SEO advice encouraged.
