What is keyword density?

Keyword density — also called keyword frequency — is the number of times a specific keyword appears on a webpage compared to the total word count. It’s often reported as a percentage or a ratio; the higher the value, the more your selected keyword appears on your page.

Why Keyword Density Matters

Keywords are a critical part of your SEO strategy .

Along with relevant content and optimized website design, ranking for the right keywords helps your site stand out from the crowd — and get closer to the top of search engine results pages (SERPs).

So it’s no surprise that a substantial amount of SEO advice centers on keywords: Doing your research can help you select and rank for top-performing keywords in your market, in turn boosting user engagement and increasing total sales.

Why? Because keywords drive searches. When users go looking for products or services, they’ll typically use a keyword that reflects their general intent, and expect search engines to serve up relevant results.

While tools like Google now take into account factors such as geographical area and page

authority — defined in part by the number of visitors to your webpage and in part by “dofollow” links from reputable sites that link back to your page — keywords remain a critical factor in website success.

The caveat? You can’t simply “stuff” as many keywords as possible into your content and expect reliable results.

This practice is called keyword stuffing, and it’s a black-hat SEO practice that can lead to penalization and even full-on removal from the SERPs.

What is keyword stuffing?

Keyword stuffing is the practice of writing low-quality content with a higher-than-average frequency of the same keyword. The purpose of keyword stuffing is to trick search engines, i.e. Google, to rank your page higher in the search engine results pages. This black-hat tactic no longer works.

During the wild west days of the first search engines, brands and SEO firms would write low-value content and cram it with keywords and keyword tags, along with links to similarly-stuffed pages on the same site. Not surprisingly, visitors grew frustrated and search engine providers realized they needed a better approach.

Now, keyword stuffing has the opposite effect — search engines will penalize the page rankings of sites that still choose to keyword stuff.

By the Numbers: The Keyword Density Formula

How do you calculate keyword density? The formula is straightforward: Divide the number of times a keyword is used on your page by the total number of words on the page.

Here’s an easy example: Your page has 1,000 words and your keyword is used 10 times. This gives:

10 / 1000 = .001

Multiply this by 100 to get a percentage, which in this case is 1%.

There’s also another formula sometimes used to assess keyword usage: TF-IDF, which stands for “term frequency-inverse document frequency”. The idea here is to assess the frequency of a keyword on specific pages (TF) against the number of times this word appears across multiple pages on your site (IDF). The result helps determine how relevant your keyword is for specific pages.

While TF is straightforward, it’s easy to get sidetracked by IDF. Here, the goal is to understand the rarity of your keyword across multiple documents. IDF is measured in values between 0 and 1 — the closer to 0, the more a word appears across your pages. The closer to 1, the more it appears on a single page and no others.

This is the “inverse” nature of the calculation: lower values mean more keyword use.

Consider this formula in practice. Applied to very common words such as “the” or “but”, the TD-IDF score will approach zero. Applied to a specific keyword, the value should be much closer to 1 — if not, you may need to reconsider your keyword strategy.

What is good keyword density?

While there are no hard and fast rules for keyword density beyond always-relevant “don’t keyword stuff” advice, many SEOs recommend using approximately 1-2 keyword for every 100 words of copy. That factors in to about 1-2% keyword density.

Your content may perform similarly with slightly more or slightly less, but general wisdom holds that Google and other search engines respond well to keyword density around 0.5%.

It’s also worth remembering the value of keyword variants — words and phrases that are similar, but not identical, to your primary keyword. Let’s say your website sells outdoor lighting solutions. While your highest-value keyword for SERPs is “outdoor lighting”, stuffing as many uses of this keyword into as many pages as possible will reduce rather than improve overall SEO.

Instead, consider keyword variants; terms that are close to your primary keyword but not an exact copy. In the case of “outdoor lighting”, variants such as “garden lighting”, “patio lighting”, “deck lighting” or “landscape lighting” can help your page rank higher without running afoul of keyword-stuffing rules.

Not sure what variants make the most sense for your website? Use the “searches related to” section at the bottom of Google’s SERP for your primary keyword. Here’s why: Google has put significant time and effort into understanding intent, so the “searches related to” section will show you similar terms to your primary keyword.

Keyword Density Tools

While you can do the math on keyword density yourself by calculating the total word and keyword counts across every page on your website, this can quickly become time- and resource-intensive as your website expands and page volumes increase.

Keyword density tools help streamline this process. Potential options include:

Want to improve your SERP position and boost site impact? Start with strong keywords.

The caveat? Keyword balance is key to search success. By finding — and regularly assessing — the keyword density of both specific pages and your site at scale, it’s possible to boost relevant SEO impact and avoid the ranking pitfalls of overly-dense keyword distribution.

keyword frequency

Whether you work in search engine optimization or you’re a part-time AdWords advertiser trying to grow your business, you may have come across the term “keyword frequency.”

So how does keyword frequency work, and how important is it to your online marketing campaigns?

Let’s review the role keyword frequency plays in search engine marketing and online advertising.

What Is Keyword Frequency?

Keyword frequency refers to how often a keyword appears on a given webpage or within a piece of content. The more frequently a keyword appears in a given page or piece of content, the higher the keyword frequency.

What is keyword frequency, keyword frequency example

Keyword frequency is closely related to keyword density.

Keyword frequency and SEO

If you’re trying to rank for a keyword organically, it’s important to be aware of your keyword frequency. If your keyword frequency is too low, you’ll have trouble ranking for that keyword unless the competition level is very low. Search engines like Google need to see “proof,” in the form of keywords, that your content is truly relevant to the query.

However, if your keyword frequency is too high, that sends a negative signal to the search engines. Avoid the black-hat technique known as “keyword stuffing,” where your keyword frequency is unnaturally high and distracting to users.

Keyword frequency and PPC

Keyword frequency matters when it comes to your paid search ads, too. If your keyword doesn’t appear in your ads at all, your ad will read as less relevant to both searchers and search engines. That lowers your click-through rate and Quality Score (which can significantly increase your costs).

However, just as in SEO, too high a keyword frequency can hurt you. In a study of top-performing AdWords ads, we found that strong ads typically only repeat the keyword twice, like this:

best ads adwords lexical diversity part 1

Compare this to an ad with much higher keyword frequency:

best ads adwords lexical diversity part 2

Our data shows that users are more likely to click lexically diverse ads than they are to click on ads stuffed with keywords. So aim for balance when considering your ads’ keyword frequency levels.

What Is a Good Keyword Frequency?

Newcomers to SEO and paid search often ask what a “good” keyword frequency is, or what guidelines they should follow when it comes to determining the right keyword density. Unfortunately, as with many elements of SEO and online advertising, there are few true “rules” regarding keyword frequency. There are, however, some generally accepted best practices that you may want to follow.

Generally speaking, many SEO professionals agree that a keyword should not appear more than once per 200 words of copy. This means that for every 200 words of copy on a webpage, a given keyword should not appear more than once.

This includes close variants of a keyword. For example, “secondhand cars” is a variant of the keyword “used cars.” Although the two terms are different, they are closely semantically related; their meanings are identical, and only their phrasing sets them apart from one another. This means you should try to space keyword variants as you would with multiple instances of the same keyword.

How Important Is Keyword Frequency?

Although keyword frequency can have an impact on how discoverable a site or webpage may be, it is just one among many such factors.

In the past, many sites got away with “keyword stuffing” – the practice of cramming as many keywords and variants as possible onto a single webpage – in an attempt to manipulate a page’s rankings. Today, however, search algorithms are significantly more sophisticated, making such techniques largely useless, and potentially even harmful.

Keyword Frequency and the User Experience

It may be more effective to think of keyword frequency not in the context of on-page SEO, but rather that of user experience.

No matter what type of content a webpage contains – a product listing, a blog post, a landing page, a thank-you page – always consider the user experience. All copy should read easily and naturally, and including forced, awkward keywords is one of the fastest ways to ruin the experience of your audience.

Keyword Frequency vs. Keyword Density

Keyword frequency and keyword density are essentially two different terms for the same principle. Both terms refer to the frequency with which keywords appear on a given webpage, which can also be called the keyword density of a webpage. As such, both terms mean the same thing and can be used interchangeably.

Keyword frequency or density can be calculated numerically. To do this, simply divide the number of instances in which a keyword appears by the total number of words on the page. For example, a 1,000-word blog post that features 10 unique instances of a keyword would have a keyword frequency or keyword density of 1%.
