High keyword density is a factor that increases the popularity and visibility of a website in the search engine results pages (SERPS). However, it is not the most important factor for appearing on search engines.


Search engine optimization (SEO) is extremely important for the development of a good web page. With the selection of good keywords that can match what people search for, webmasters develop quality web content. Although keyword research may be really time consuming, if done properly it can provide a website with high traffic level.

What is Keyword Density?

Keyword density (KD) is a key element of SEO that counts the density of the main keywords throughout the website. By measuring the number of times a particular keyword shows up on a web page against the total number of words on the page, keyword density indicates how relevant a web page is to this particular keyword. For instance, if a keyword occurs 5 times in a web page of 500 words, the keyword density of the web page is 0.01, by dividing 5 by 500. Keyword density is always calculated as a percentage of the total words on the page and therefore on this example it is 0.1%.

Is a High Keyword Density a Good Factor?

Generally, a high keyword density is a factor that increases the popularity and visibility of a website in the search engine results pages (SERPS). Search engines drive traffic to a website based on the content. In the context of SEO, if a web page has a sufficient number of keywords, and a high keyword density, it is highly likely to be noticed in search engines and achieve higher search engine ranking. Although keyword density is evaluated differently by major search engines, there is no doubt that a keyword occurring twice in a web page of 500 words has a low keyword density as opposed to a keyword occurring five times in a web page of similar length.

Improving keyword density

For web pages that have low keyword density, there are methods to improve it in order to achieve higher ranking in search engines.

First of all, avoid repeating the same keywords. Using keywords extensively may result in the website being banned from search engines as a spam. This happens because search engines are smart enough to process keywords and identify which of them appear repeatedly in a senseless sequence. Therefore, it is strongly recommended to use keywords in a sequence that makes business sense, helping the web page achieve a high ranking in the SERPS for that particular keyword.

Only if the website has many pages, it makes business sense to use the same keywords throughout the website to achieve a higher keyword density because keywords are more evenly allocated in each page without being overused on each page. Besides, if the website has more pages, it offers the opportunity to use more keywords and achieve a large amount of popular search phrases throughout the website.

Secondly, make sure the keywords match the industry or the sector your business operates in. Search engine optimization is based on the selection of right keywords that reflect the products or services of a firm as these are expected to be searched for by consumers. Therefore, keywords that are irrelevant to the industry, products or services, in other words, wrong keywords are highly likely to keep the web page off-traffic, minimizing popularity and decreasing sales.

There are also software packages for checking keyword density. One of the most successful is Web CEO Software that allows evaluating and altering keyword density very easily. Besides, Web CEO provides information about websites that are directly linked to a website and possibly affect the keyword density of a particular web page. For more information, visit

Is Keyword Density So Important After All?

According to webmasters, a keyword density between 3% and 4% is considered good for a web page to have good chances to appear on search engines. However, there are websites that rank in top positions with lower keyword density, indicating that it may be an important factor, but not the most important factor for appearing on SERPS.

For some webmasters, keyword density is an overvalued factor. There are web pages with keyword density of 0.05% that are more relevant in the keyword density range than web pages with keyword density of 3% or more. This is explained by the fact that some keywords are more meaningful than others because they are less used. In other words, the less used, the more they weigh in the relevancy of a web page.
