When we talk about what is keyword difficulty in SEO, we’re basically asking: How hard will it be to rank for this keyword on Google (or any search engine)?

It’s like checking the level of competition before jumping into a game. Some keywords are tough because established websites with high authority are already targeting them.

If you go after these, you’ll likely need solid content, strong backlinks, and time to build authority.

On the flip side, keywords with low difficulty don’t have as much competition. They’re easier wins, though they usually bring in less traffic compared to the “big” keywords.

Knowing keyword difficulty helps you choose smarter.

Instead of guessing, you can decide whether it’s worth chasing high-competition terms or focusing on easier keywords that can get you results faster. 

In this post, we will explore everything you need to know about keyword difficulty, matching your SEO goals with the right opportunities.

What is Keyword Difficulty?

Keyword difficulty refers to how challenging it is to rank for a specific keyword or search term on search engines like Google. 

It is a critical metric in SEO because it helps marketers assess the level of competition for a keyword and determine the resources required to achieve high rankings, a process well-understood by any top digital marketing agency focusing on results-driven campaigns.

High-difficulty keywords typically require more content, backlinks, and optimization efforts, while low-difficulty keywords are easier to rank for but may have lower search volume.

Understanding Keyword Difficulty vs. Keyword Competition

When working with SEO, it's important to understand the distinction between "Keyword Difficulty" and "Keyword Competition." Although they may sound similar, they are two separate concepts that help in planning SEO strategies.

Aspect Keyword Difficulty Keyword Competition
Definition Measures how difficult it is to rank for a specific keyword in organic search results. Refers to the level of competition in paid search when bidding for a keyword.
Focus Area Organic Search (SERPs) Paid Search (Google Ads)
Purpose Helps assess the likelihood of ranking for a keyword based on competition from other websites and overall search engine optimization factors. Indicates the level of competition you might face when bidding for a keyword in Google Ads.
Measurement Usually represented as a score, ranging from low to high difficulty based on factors like domain authority, backlinks, and content quality. Typically indicated by the "Competition" metric in Google Keyword Planner, which shows how many advertisers are bidding on that keyword.
Relevance Most relevant for SEO efforts aiming to improve organic rankings over time. Primarily relevant for paid search campaigns and ad strategy.
Examples Ranking for "best digital cameras" or "buy running shoes" organically. Competing with other advertisers for "digital camera sales" or "discount running shoes."

Both Keyword Difficulty and Keyword Competition are crucial for SEO and PPC strategies, but they apply to different aspects of your online marketing efforts. Understanding the difference allows you to make more informed decisions in your digital marketing strategy.

The Importance of Keyword Difficulty in Keyword Research

When conducting keyword research, SEO teams typically prioritize content opportunities based on two key factors: search demand and competition. But how do you determine whether you have the potential to rank for a given keyword?

This is where keyword difficulty in SEO comes into play.

When optimizing your site for a new topic, it’s often most effective to target keywords that are easier to rank for, yet still attract a reasonable amount of search volume. These are commonly referred to as "low-hanging fruit" keywords. Since they face less competition, they can quickly drive traffic to your site without requiring heavy resources.

Focusing on low-difficulty keywords can also have significant long-term advantages. By optimizing content around long-tail keywords and strategically interlinking it, you can create a topic cluster around a specific subject. OOver time, this helps search engines recognize your website as an authoritative source, which can increase your chances of ranking for more competitive, high-traffic keywords. Centric, a digital transformation agency, helps businesses leverage such keyword strategies for better online visibility and growth.

Keyword difficulty meaning is crucial for understanding how much effort you'll need to rank for certain terms. A good strategy for new websites is to focus on SEO keyword difficulty that's on the lower end of the scale while gradually increasing the difficulty as your site gains authority and backlinks.

What Is a "Good" Keyword Difficulty Score?

A good keyword difficulty score varies depending on your SEO strategy and the competitiveness of your niche. However, here’s a general guideline:

  • Low Difficulty (0-30): These are the easiest keywords to rank for. Although they tend to have lower search volumes, they’re ideal for new websites or for targeting longer-tail keywords. They represent prime opportunities for rapid wins.
  • Medium Difficulty (31-60): These keywords are moderately competitive. They usually offer a balance between search volume and competition. Established websites with some domain authority can effectively target these keywords with optimized content.
  • High Difficulty (61-100): These are the most competitive keywords, usually dominated by authoritative sites with strong backlinks. Targeting high-difficulty keywords typically requires substantial time, resources, and a well-established online presence.

Keyword difficulty tools can help you assess the competitiveness of a keyword, allowing you to prioritize efforts based on real-time data. If you're looking for a keyword difficulty tool free, many platforms offer basic analysis tools to help you get started. For more detailed insights, it’s worth investing in the best keyword difficulty tool.

Striking the Right Balance

Ultimately, the "best" keyword difficulty score depends on your website’s authority, available resources, and your overall SEO goals. The key is to strike a balance between targeting achievable keywords and aiming for those with substantial traffic potential. By leveraging low-difficulty keywords as stepping stones, you can build authority and gradually work your way up to more competitive keywords. In this way, understanding how to find keyword difficulty can guide your strategy and lead to better, more sustainable results in the long term.

5 Key Factors Affecting Keyword Difficulty 

It includes search volume, domain authority, backlinks, content quality, and competitor strength, all influencing how challenging it is to rank for a keyword.

1. Search Volume

Keywords with higher search volume typically face more competition, as many businesses target these terms to capture larger audiences. This is particularly true in local SEO keyword research, where competition can vary significantly depending on geography and niche.

2. Domain Authority

Websites with strong domain authority are more likely to rank for competitive keywords. Higher authority sites are trusted by search engines, making it easier for them to rank.

3. Backlinks

The quality and quantity of backlinks a website has directly affect its ability to rank. Websites with a robust backlink profile tend to rank better for challenging keywords.

4. Content Quality

Well-structured, relevant, and detailed content is essential for ranking higher. High-quality content not only attracts more traffic but also increases the likelihood of earning backlinks.

5. Competitor Strength

The strength of the websites ranking for the keyword plays a significant role. If these top-ranking pages have high domain authority, backlinks, and optimized content, it becomes more challenging to outrank them.

Keyword difficulty is typically measured on a scale from 0 to 100, where a higher score indicates greater difficulty. The score is derived based on several parameters:

  • Search Volume: High search volume often correlates with high competition, which increases difficulty.
  • Competition: If multiple strong competitors are targeting the same keyword, the difficulty increases.
  • Backlinks: Pages with a high number of quality backlinks are often harder to outrank.

  • High (60-100): Keywords in this range are highly competitive, usually with high search volume and multiple well-established competitors. Achieving a high ranking for these keywords requires significant SEO efforts, including high-quality content, extensive backlink strategies, and an authoritative website with strong domain metrics.

9 Easy Steps to Choose Keyword Difficulty

When reviewing keyword difficulty scores, it’s not just about picking a specific number, it’s about truly understanding what is keyword difficulty and how it reflects the competition around a keyword.

The smartest strategy often involves a mix: pursue a few competitive keywords for long-term growth while building momentum with low to medium-difficulty keywords that offer quicker wins.

Keyword difficulty scores are a helpful metric to gauge the level of competition for each keyword, but they’re just one piece of the puzzle. 

Here’s how you can approach it:

1. Enter Your Seed Keyword

Enter your seed keyword into an SEO tool that provides search volume and keyword competition or difficulty metrics.

2. Build a Keyword List

Select all relevant keyword options and save them in a list.

3. Export to Spreadsheet

Export the list to Google Sheets or Excel for further analysis.

4. Sort by Search Volume

Sort the list by search volume, starting with the highest.

5. Apply Color Scales

Apply color scales to the search volume and keyword difficulty columns for easier visual comparison, just as learning how to search a word on a website makes analyzing content or finding key information more efficient during the SEO research process.

6. Identify Keyword Opportunities

Look for keywords with high search volume and lower difficulty scores.

7. Choose Primary and Secondary Keywords

Choose one or two primary keywords and a few secondary ones that best fit your goals.

8. Check Search Intent

Evaluate the search intent behind these keywords and review the pages that are currently ranking. Be honest about whether you can create content that fulfills this intent.

9. Refine Your Keyword List

Remove any keywords that don’t align with the search intent or your content strategy.

Keep in mind the authority of your domain. If you’re a large brand with high authority, you may not need to worry as much about competition, whereas smaller businesses should focus on less competitive keywords to gain traction in search results.

Keyword Difficulty and its Impact on Strategy

Keyword difficulty directly shapes how you plan and execute your SEO strategy.

High-difficulty keywords usually mean strong competition from authoritative websites, which often require significant investment in high-quality content, backlinks, and domain authority to stand a chance of ranking.

While these keywords can deliver large amounts of traffic, they also demand more time, effort, and resources.

On the other hand, low-difficulty keywords give you quicker wins.

These terms may not drive massive traffic, but they’re easier to rank for and can steadily build your site’s visibility.

Targeting these keywords helps smaller or newer websites gain traction before competing for harder, high-volume terms—a strategy often recommended by agencies offering digital marketing services to ensure steady growth and ROI.

The smartest strategy is often a mix: pursue a few competitive keywords for long-term growth while building momentum with low to medium-difficulty keywords.

This approach reflects broader marketing efforts, similar to what are five marketing strategies that retailers spend half of their annual budget on?, where prioritization is key to balancing short-term wins with long-term gains.

This balance ensures you’re not only chasing big opportunities but also capturing realistic traffic that supports your overall business goals.

FAQs: What is Keyword Difficulty?

What is keyword difficulty with example?

Keyword difficulty (KD) refers to how hard it is to rank on the first page of search engine results for a particular keyword. It takes into account factors like the number and quality of backlinks, domain authority, content quality, and how competitive the search results are for that term. For example, the keyword "buy shoes online" might have a high keyword difficulty due to strong competition from established e-commerce websites, while "buy handmade shoes in London" might have lower difficulty due to fewer competing pages.

What is a good keyword difficulty score?

A good keyword difficulty score depends on your site's authority, but generally, a score under 30 is low competition, 30-50 is moderate, and above 50 is high difficulty. For new websites, targeting keywords with low keyword SEO difficulty (below 30) is ideal.
