Keyword difficulty (KD) is a fundamental parameter for planning an effective SEO strategy. Understanding what it is, how to evaluate it, and how to use it to choose the right keywords can make the difference between an invisible website and a well-positioned site that converts. In this article, we’ll explore the various aspects of keyword difficulty and its role in creating a winning SEO strategy.

What is keyword difficulty?

Keyword difficulty is a metric that measures how difficult it is to rank in search results for a specific keyword. It’s calculated by analyzing several factors, including:

• The authority of competing sites that are already ranked for that keyword.
• The quality and quantity of content covering the topic.
• The volume of backlinks supporting that content.

The higher the keyword difficulty, the greater the effort required to achieve good positioning. This metric is particularly useful for avoiding investing resources on keywords that are too competitive, focusing instead on more accessible opportunities.

How to evaluate keyword difficulty

To evaluate keyword difficulty, it’s important to use specific SEO tools like SEMrush, Ahrefs, or Moz. These tools assign a difficulty score, generally expressed on a scale from 0 to 100. Here’s how to interpret these scores:

• 0-20: low difficulty, ideal for new sites or those with little authority.
• 21-50: medium difficulty, requires good optimization and quality content.
• 51-100: high difficulty, recommended for established sites with a strong backlink strategy.

Beyond the score, it’s useful to analyze:

• Monthly search volume: a keyword with high difficulty and low volume might not be a good investment.
• Search intent: ensure the keyword is relevant to your audience.
• Competitor content: study the top results to understand what makes them effective.

How to choose the right keywords

The right keywords for SEO aren’t always those that generate the most traffic, but those that convert the most. A high-volume keyword doesn’t necessarily guarantee results, while a specific and less competitive keyword can attract a targeted audience.

Here are some criteria for choosing keywords:

1. Search intent: identify whether the user is looking for information, wants to purchase, or perform a specific action.
2. Relevance to your business: ensure the keyword is relevant to your products or services.
3. Competitiveness: assess whether you have the necessary resources to compete with already-ranked sites.
4. Commercial value: prefer keywords that attract users willing to convert.

Example: an e-commerce site selling shoes might choose “waterproof running shoes” instead of “running shoes.” The first keyword, while having lower volume, attracts an audience with specific needs and a higher likelihood of conversion, also thanks to easier positioning due to lower keyword difficulty.

Focus keywords and long tail keywords

An effective SEO strategy requires balancing focus keywords and long tail keywords. Here’s how to differentiate and use them:

Focus keywords

Focus keywords are short, generic keywords that represent a main topic. These keywords often have high search volume and higher keyword difficulty. For example, terms like “running shoes” or “SEO” can attract a broad audience, but require extremely high-quality content and strong authority to rank at the top of search results.

Focus keywords are ideal for:

• Building site authority on a specific topic.
• Creating main pages (pillar pages) that serve as reference points for related content.
• Attracting general traffic that can be guided to other site pages.

However, due to their competitiveness, they’re not always the best choice for those with limited resources or a new site.

Long tail keywords

Long tail keywords, on the other hand, are longer, more specific phrases targeting a niche audience. Examples of long tail keywords include “waterproof running shoes for winter trails” or “how to choose the best hosting for a WordPress site.”

These keywords offer several advantages:

• Lower competition: thanks to their specificity, they attract fewer competitors compared to focus keywords.
• Higher conversions: users who use long tail keywords often have more defined search intent, making them more likely to take action (purchase, subscribe, etc.).
• Content adaptability: they can be easily integrated into blog articles, FAQs, and practical guides.

How to combine them in an SEO strategy

A balanced approach that integrates focus keywords and long tail keywords is essential for maximizing results. Here’s how to do it:

1. Create a pyramid structure: use focus keywords for main pages and build around these more specific content optimized for long tail keywords.
2. Content interconnection: link pages optimized for long tail keywords to main pages to improve navigation and increase site authority.
3. Adapt content to the conversion funnel: focus keywords attract a broader audience at the top of the funnel, while long tail keywords guide users toward purchase or other actions at the bottom of the funnel.

Practical example:

Imagine a site selling fitness equipment. The main page could be optimized for the focus keyword “gym equipment.” Within it, you could link articles covering long tail keywords like:

• “How to choose a treadmill for small spaces”
• “Adjustable dumbbells vs fixed dumbbells: which to choose?”
• “Complete guide to buying an exercise bike for beginners”

This strategy not only improves positioning for a wide range of keywords, but also increases time on site and conversions.

Keyword difficulty over time

Keyword difficulty is not a static metric. Over time, some keywords become more competitive, while others lose relevance. It’s essential to regularly monitor your keywords and adapt your SEO strategy accordingly to keep pace with market and search engine changes.

1. Emerging keywords: identify industry trends to anticipate competition. For example, use tools like Google Trends to identify growing searches in your sector. Integrate these emerging keywords into your content before they become highly competitive, ensuring an initial advantage.
2. Content updates: optimize existing articles to maintain positioning or improve performance. This may include adding new information, improving readability, or integrating recent data. Search engines appreciate updated content, thus increasing the chances of remaining visible for strategic keywords.
3. Focus keyword rotation: alternate attention on different main keywords to diversify traffic. Concentrating efforts on a single group of keywords can make your site vulnerable to algorithmic changes. Adopt a rotation strategy to cover more related topics, thus ensuring stable and diversified presence in search results.
4. Continuous performance monitoring: use tools like Google Search Console to analyze your keyword performance over time. Identify which keywords are losing effectiveness and plan targeted interventions, such as creating additional content or revising link building strategies.
