What is keyword density?
Keyword density is the extent to which the keyword appears on the web page. For example, if your web page is focusing on the term “mortgage calculation,” it’s vital that this combination of words appears more often on the page. Google’s crawlers are constantly scanning web pages to ensure that users are given the right/relevant search results. It is important that for the relevant keywords you are trying to rank on, that your pages are focused on these keywords as well. So if your page is focused on the term mortgage calculation, it is a sign to the crawlers that a searcher looking for “mortgage calculations” can find what they are looking for on your webpage. In addition, the keywords in the heading tags also matter for keyword density. So it’s not just about the keywords in the main text, but also keywords in the headings.
The right keyword density
The rule of thumb when it comes with keyword density is aim for a density between 1 and 3%. Keyword density can be calculated by dividing the number of times the focus keyword appears by the total number of words on the page.
As an example, you focus the web page on the term “cavity wall insulation”. The term appears 25 times on the web page. The total number of words on the page is 636. The formula then is: 25/636 * 100% = 3.9%.
This means that the keyword density of the page is too high. It is important to stay away from keyword stuffing or over-optimizing. Yes, that is absolutely possible.
Keyword stuffing is the over-representation of the focus keyword in the overall text. It is essentially, when the same keyword or phrase appears on a page over and over again. Google penalizes this as it is detracting to the reader and has a negative impact on the readability and user experience. So it is important to pay attention to this factor when creating any piece of content for your website.. You have several ways to combat keyword stuffing. Consider:
- Minimizing the appearance focus keyword.
- Replacing the focus keyword with a synonym.
