One of the most effective ways to refine your SEO strategy and capture more organic traffic is through keyword gap analysis.
This technique helps you uncover the keywords your competitors are ranking for that you’re missing out on, allowing you to adjust your content and SEO efforts accordingly.
In this blog post, we’ll explore how to conduct a keyword gap analysis to uncover new opportunities and improve your search engine rankings using Semrush, a leading SEO tool known for its comprehensive data and intuitive interface.
What is Keyword Gap Analysis?
Keyword Gap Analysis is a process of comparing your website’s keyword profile against your competitors. It helps you identify:
- Keywords your competitors rank for that you don’t
- Keywords you’re both targeting, but where they’re outperforming you
- Your unique keywords that competitors aren’t targeting

Why Keyword Gap Analysis Matters
The online market is saturated, simply targeting high-volume keywords isn’t enough. You need to understand the nuances of your competitive niche.
Keyword Gap Analysis allows you to:
- Discover untapped opportunities

- Allocate resources more effectively
- Stay ahead of market trends
Get Started with the Semrush Keyword Gap Tool
To get started with the Keyword Gap Tool, log into your Semrush account and navigate to the Keyword Gap tool under the “Competitive Research” section.
Enter your domain in the first box, then add up to four competitor domains in the subsequent boxes.
Once you enter your domain name, Semrush will automatically suggest some competitors you can choose from. Otherwise, enter your own competitor domains.
Select your target country and choose between organic keywords, paid keywords, or PLA keywords. Finally, click Compare.
Choosing the Right Competitors
Selecting the right competitors is crucial for meaningful analysis. Consider:
- Direct business competitors
- Websites ranking for your target keywords
- Industry leaders and up-and-coming brands
You can use Semrush’s Organic Competitors report to identify your top organic search competitors if you’re unsure who to analyze.
Understand the Keyword Gap Interface
Once you’ve entered the domains, you’ll be presented with a wealth of information. Let’s break down the key elements:
1. Venn diagram overview
At the top of the page, you’ll see a Venn diagram-style visualization showing the keyword overlap between the analyzed websites. This gives you an immediate visual understanding of your competitive landscape.
2. Detailed keyword table
Below the Venn diagram, you’ll find a comprehensive table with various metrics for each keyword, including:
- Keyword
- Volume
- Keyword Difficulty
- CPC
- Competition Level
- SERP Features
- Intent
- Trend
Domain Comparison Columns
For each domain you’ve entered, you’ll see columns showing:
- Position
- Volume
- Traffic %
- Costs %
- URL
This allows for quick comparisons across domains for each keyword.
Features to Explore On the Keyword Gap Tool
1. Keyword overlap types:
Semrush categorizes keywords into different overlap types:
- “Unique to the first domain’s keywords”: Keywords only your site ranks for
- “Common keywords”: Keywords all analyzed domains rank for
- “Unique keywords”: Keywords only found on one of the competitor sites
- “Shared keywords”: Keywords shared by two or more, but not all, domains
2. Advanced filters:
To refine your analysis, use these advanced filters:
- Keyword difficulty
- Search volume
- SERP features
- Word count
- Intent (informational, transactional, navigational, commercial)
3. Keyword types:
Semrush classifies keywords into four types:
- “Shared”: Keywords you and your competitors are ranking for.
- “Missing”: Keywords some competitors rank for, but others (including you) don’t
- “Weak”: Keywords where competitors outrank you
- “Strong”: Keywords where you outrank competitors
- “Untapped”: Keywords your competitors rank for, but you don’t
- “Unique”: Keywords you are ranking for, but other competitors are not.
- “All”: Keywords for which at least one of the entered domains has rankings.
