Digital Marketing Marketing Metrics

What is Keyword Difficulty?

Keyword Difficulty explained clearly with real-world examples and practical significance for marketers.

Keyword Difficulty is a metric that measures how challenging it would be to rank on the first page of search engine results for a specific keyword, typically scored on a scale of 0-100 where higher scores indicate greater competition.

What is Keyword Difficulty?

Keyword difficulty evaluates the competitive landscape for search terms by analyzing factors like the authority of currently ranking pages, the number of referring domains, content quality, and search volume. Most SEO tools calculate this metric using proprietary algorithms that weigh different ranking factors to produce a single difficulty score.

The basic formula considers several key components:

Keyword Difficulty = (Domain Authority of Top 10 Results + Page Authority + Content Quality + Backlink Profile + Search Volume) / Weighted Algorithm

For example, the keyword “best running shoes” might score 85/100 in difficulty because the top results include established e-commerce sites like Amazon, Nike, and Runner’s World with domain authorities above 80, thousands of referring domains, and comprehensive content. Meanwhile, “best trail running shoes for muddy terrain” might score 45/100 due to fewer high-authority competitors and more niche content opportunities.

Different tools use varying methodologies. Ahrefs focuses heavily on the number of referring domains to top-ranking pages, while SEMrush incorporates more on-page factors and user behavior signals. Moz emphasizes domain and page authority metrics from their own index. These differences can result in the same keyword receiving scores of 60 on one platform and 75 on another.

Keyword Difficulty in Practice

HubSpot, the marketing software company, targets keywords across the difficulty spectrum strategically. They compete for high-difficulty terms like “marketing software” (difficulty score 78) where they rank on page one despite fierce competition from Salesforce and Adobe. However, they also target lower-difficulty long-tail keywords like “marketing automation for small businesses” (difficulty score 34) to capture more qualified traffic with less competition.

Backlinko founder Brian Dean demonstrated this approach when launching his SEO training course. Instead of targeting “SEO course” (difficulty 89), he focused on “SEO training online” (difficulty 52) and “learn SEO” (difficulty 41). This strategy helped him achieve first-page rankings within six months while building authority for more competitive terms later.

Local and Niche Opportunities

Local businesses often find success with location-based keywords that show dramatically lower difficulty scores. A Denver law firm might struggle with “personal injury lawyer” (difficulty 84) but easily rank for “personal injury lawyer Denver Colorado” (difficulty 28).

Sporting goods retailer REI uses this principle by targeting city-specific terms like “hiking gear Seattle” (difficulty 35) rather than competing solely on “hiking gear” (difficulty 76). E-commerce sites frequently balance high-volume, high-difficulty product terms with specific model numbers and features. Best Buy competes for “laptop” (difficulty 82) while also targeting “Dell XPS 13 2024 review” (difficulty 23) to capture buyers at different stages of the purchase funnel.

Why Keyword Difficulty Matters for Marketers

Understanding keyword difficulty enables marketers to allocate resources effectively and set realistic timeline expectations for organic search campaigns. Targeting only high-difficulty keywords without sufficient domain authority often results in pages buried beyond the first few result pages, generating minimal organic traffic.

Keyword difficulty scores help prioritize content creation and link building efforts. Marketers can identify quick wins with low-difficulty, high-intent keywords while simultaneously working toward longer-term rankings for more competitive terms. This approach maximizes return on investment by generating traffic and conversions from attainable keywords while building the authority needed for premium search terms.

The metric also influences budget allocation between paid and organic strategies. Keywords with difficulty scores above 80 might require extensive content development, outreach campaigns, and months of consistent effort, making pay-per-click advertising more cost-effective initially while organic efforts develop.

FAQ

What is a good keyword difficulty score to target?

New websites should focus on keywords with difficulty scores below 30, while established sites with strong domain authority can compete for terms scoring 50-70. Scores above 80 typically require significant resources and established authority to rank competitively.

How does keyword difficulty differ from search volume?

Keyword difficulty measures competition level and ranking difficulty, while search volume indicates how many people search for a term monthly. High-volume keywords often have high difficulty scores, but many low-competition terms also have substantial search volume, particularly in niche markets.

Do keyword difficulty scores change over time?

Yes, keyword difficulty fluctuates based on competitor activity, algorithm updates, and market changes. Seasonal trends, new competitors entering the space, or major brands shifting their SEO focus can increase or decrease difficulty scores for specific terms.

Which keyword difficulty tool provides the most accurate scores?

No single tool provides definitive accuracy since search algorithms remain proprietary. Ahrefs, SEMrush, and Moz each use different methodologies, so marketers often compare scores across multiple platforms to gain a comprehensive understanding of competitive landscapes.
