Keyword density refers to the number of times a specific keyword appears in a given piece of content or webpage. It is also referred to as keyword frequency. But, how important is keyword density, and is it still relevant for SEO?
Content is king, and keyword density is the foundation of Search Engine Optimization and has a direct impact on the visibility of your site content’s Search Engine Results Pages or Search Engine Ranking Pages, in addition to the costs of your site’s marketing campaign.
What is the Right Keyword Density for SEO?
As we just mentioned, keyword density pertains to the number of times a specific key phrase or keyword shows up within a certain piece of content or a webpage as a percentage or ratio of the full word count.
When it comes to the formula for keyword density, it can be evaluated as a definite figure, if need be. So if you were trying to figure out a webpage’s keyword density or piece of content’s keyword density, you would simply divide the total number of words by the number of times the given keyword appears on that page. This will give you those specific pages or a piece of content’s keyword density.
When it comes to keyword density, there are no clearly defined rules, as is the case with all facets of SEO. So one thing that you’re not going to find is directions from Google telling you the number of keywords your content can and should contain, neither are you going to find specific steps or figures that you can depend on to guide you on keyword density.
However, there are some reflections that may be able to help your content out and ensure that your content is effective enough to increase your visibility and boost the ultimate exposure and experience of your audience.
When SEO was in the process of making an appearance, around a decade ago, a technique referred to as “keyword stuffing” was quite popular. The action of filling as many keywords as you want inside a piece of content or on a webpage is known as keyword stuffing. However, this method of SEO felt forced and strange to the reader. As you, would imagine, the entire flow of the content would be ruined and leave the user with a less than desirable experience after reading the content.
This was ultimately achieved by including footers that were lengthy at the end of pieces of content or web pages, and these footers contained hundreds of keyword variations of frequent or everyday search terms. This practice was most often noticed on hotel websites. They would frequently display footers that contained hyperlinked keywords, and these keywords would take readers to web pages that featured a similar or related stuffed footer.
In today’s post-Panda world, this practice is odd and less frequent. The technique did, however, offer dishonest search engine optimization advantages in this way for site owners to rank high on Google’s results for practically every keyword you would think of.
And the only reason they got away with it is that Google’s algorithms were not as developed or enlightened enough to decipher these keyword-crammed pages for what it was. Ultimately, it was a cheap hack to manipulate the SERPs, so these pages would rank high on Google’s results.
However, this is not the case today. Google has made lots of changes to search algorithms, and as such, you should refrain from stuffing keywords into web pages as often as possible as it will probably have less than desirable results when it comes to ranking.
Where Do Keyword Variants Come in?
So if you didn’t already know, over 5 billion searches are handled by Google every day. Every day approximately 15% of those searches are brand new. This means completely new as in, no one has ever searched for those keyword terms in human history before.
How is this possible?
This is very much a reality nowadays since people don’t search the same way they used to years ago. The introduction of artificial intelligence and voice search features on computers and mobile devices has basically changed how users interact with search engines. It’s now frequent or usual to find that organic traffic is driven by hyper-specific search queries, questions, and sentences.
This is because focus keywords now play a different role, and longtail keywords have become more crucial. So keyword repetition no longer controls the relevance or outcome of SEO. So each target keyword is basically a bucket that holds modifiers, plurals, rephrased searches, sentences, and other positively related search terms. On the flip side, once a keyword becomes a bucket, it isn’t easy to decipher keyword density for that specific term.
However, this doesn’t mean that you should stop optimizing for specific keywords. However, do remember that you’re not simply optimizing for those terms on its own. You are optimizing for hundreds of keywords that are related to that specific keyword.
How Do Keywords Affect the User Experience?
So Google has a new algorithm known as RankBrain, and it basically gives Google the cue to start indexing more semantically.
So when someone searches for “where to find bats,” they could either be looking for baseball bats or the other bats, which are the furry, flying mammals. To offer the best content and find out which type of bat the individual is searching for, personalized content such as the user’s Google search history and location will be pulled by Google.
Google does also has its ways of deciphering whether a webpage is relevant for a certain keyword, contextually.
