Through our SEO Agency Optimize 360.

Le natural referencing is a major challenge for companies and individuals who want to make the most of their online presence.

Among the many optimisation techniques and strategies to be considered, the choice of keywords is crucial.

With this in mind, the notion of Keyword Difficulty (KD) makes perfect sense. In this article, we explore this concept and how it can help SEO experts to improve their performance.


What is Keyword Difficulty or KD?

La Keyword Difficultyalso known by the abbreviation "KD", is an indicator expressed as a percentage, generally between 0 and 100, which assesses the complexity of the natural referencing a keyword on search engines. The closer this score is to 100, the more difficult it is to rank for this keyword in the first results of Google and other search engines.

This value is generally the result of a combination of several factors, such as the level of competition for this keyword, the search volumethe relevance of existing content and the authority of sites that are currently well ranked for this keyword.

Why is KD important for SEO experts?

Knowing the difficulty of a keyword is essential for SEO experts because this allows them to better direct their efforts and their optimisation strategy. Based on this information, they can choose to concentrate their resources on keywords for which they have a better chance of achieving good positioning in the search results.

In addition, the KD gives them an idea of the level of competition on a specific keyword and therefore of the amount of work needed to rank well. This can help them adjust their approach to get the best possible return on their SEO investment.

How do you measure Keyword Difficulty?

There are several tools and methods for determining KD:

  • Manual analysis of competitor sites: This method involves examining the first 10 websites that appear in search results for a given keyword in order to assess their authority, relevance and content quality. Although this approach can give a rough idea of the difficulty, it is generally considered to be less accurate than using automatic tools.

  • SEO tools for measuring KD : There are various SEO tools available on the market that provide KD estimates for keywords. These tools generally take into account factors such as the number of backlinksdomain authority or search volume to determine the KD. The most popular tools include SEMrush, Ahrefs, Moz and Ubersuggest.

Factors taken into account when calculating Keyword Difficulty

Each KD measurement tool or method will use slightly different factors to estimate the complexity of a keyword. Here are the main factors generally taken into account:

    1. Level of competition : a keyword that is very popular and sought after by Internet users will also attract the attention of companies and content creators, making the competition more intense.
    2. Search volume : when few Internet users are searching for a keyword, it can be easier to position yourself on that keyword. On the other hand, if volumes are high, this can make the task more difficult.
    3. Relevance of existing content : if the pages currently ranked for a keyword offer high-quality content that is relevant to users, they will be harder to unseat.
    4. Authority for top-ranked domains : when websites with a solid reputation are already ranked highly for a keyword, it will be more difficult to surpass them, even with high-quality content.

How can KD be used to improve your SEO strategy?

Once the difficulty of the keywords has been assessed, here are a few tips for optimising your strategy based on this information:

  • Target low-KD keywords: if certain keywords that are relevant to your business have a relatively low difficulty level, it may be wise to target them as a priority to rapidly improve your chances of appearing in the first results.

  • Improving the quality of content : To tackle the most competitive keywords, it's essential to create high-quality, informative content. Pay particular attention to the structure, style and relevance of the information provided.

  • Obtaining quality backlinks : Domain authority is often a key element in calculating KD, and obtaining inbound links from reputable websites reinforces this authority. So put in place a netlinking to maximise your chances of success.

In short, Keyword Difficulty (KD) is a valuable indicator for directing SEO efforts by choosing the keywords best suited to your natural referencing strategy.

By measuring KD and implementing an appropriate methodology for targeting the most accessible keywords, SEO experts can maximise their impact and improve their performance in terms of online visibility and the generation of qualified traffic.
