Keyword density in SEO means how often a keyword appears in a piece of writing in relation to the total number of words.
It’s often show as a percentage. To find it, divide the number of keywords on the page by the total words on the page, and then multiply by 100.
Here, we will show you with example, when main keyword will be using 10 times in a 1000-word article, then keyword density will be 1%. If you try to use it 30 times, the keyword density will be 3%.
What is Keyword Density in SEO?
Keyword density is how often a specific phrase shows up in your writing. In the past, SEOs focused on it too much, leading to articles filled with keywords that were hard to read.
So, thankful, search engines are better now.
They now focus more attention to the context and instead of just repeating keywords. This means that having a lot of keywords isn’t as important before, but it still matters a bit. It can still show that your content is relevant, and new tools can help you to check how properly you’re doing this.
Let’s explain why keyword density is still important (a bit), how to measure it, and how to find the right balance in between SEO and easy reading.
Keyword Density Formula
You can calculate keyword density as a number if you want. To find the keyword density of a webpage, just divide how many times a keyword is used by the total number of words on the page. This number is the keyword density for that page.
What Is TF-IDF?
TF-IDF, which means ‘term frequency and inverse document frequency,’ is a better method for measuring how often a word appears in a text.
This measure helps find out how important a word is in a document. Search engines might use different versions of TF-IDF to see how relevant a page’s content is to what a user is searching for. But, there are many other SEO factors to consider too.
Why Keyword Density Is Important?
Keyword density was a significant factor in search engine optimization (SEO) for several reasons. However, over time its important has diminished. Here are some historical reasons why keyword density was important in the past:
Search Engine Ranking Algorithms: In the past, search engines used simpler methods, and keyword density was a key measure to find out what a webpage was about and how relevant it was. Pages with more keywords were usually seen as more relevant for certain searches.
Content Relevance: Keyword density showed how well the content matched what a user was searching for. More keywords meant the content was probably closer to what the user wanted.
Content Optimization: Website owners and SEO experts thought that by placing keywords carefully in their content, they could help their pages rank better for those keywords. This resulted in a method called keyword stuffing; where too many keywords were added to the content to try to trick search engines.
Keyword Density vs. Keyword Stuffing
Keyword density suggests how often to use a keyword naturally, while keyword stuffing means adding keywords to a webpage in a way that feels forced.
This is a useless SEO trick that tries to change search results. It helps a webpage show up for many keywords at the same time, but gives no real value.
In the early day of SEO, adding many keywords to a page work well. This was because search algorithms were are not smart now. Just adding lots of keywords was enough to get a good ranking.
After Google updated its Penguin algorithm, using too many keywords stopped working.
Today, using this bad SEO method goes against Google’s spam rules. Doing this could result in penalties, making your website completely vanish from search results.
Can You Rank Without a Specific Keyword Density?
Yes! You can achieve it. You should still pay attention to keywords, but the algorithm works differently now.
In 2025, Google uses smart search to see how well you answer a question. Its system doesn’t see just your exact words; instead of, this also considers ideas, phrases, and how they relate to each other to easily understand meaning.
Semantic search is more than just checking keywords. It considers what the person is trying to find, the tone, feelings, and other factors to get the best answer to a search question.
You should still use keywords, but make sure they flow well in the text and cover the topic fully.
In simple terms, it’s more important to meet what people are looking for and provide what they need. Keywords should fit naturally into the text, not be the main goal.
