As the old saying goes, “keep your friends close and your competitors closer.”
Competitor keyword analysis is one of the fastest, most reliable shortcuts in SEO. Your top-ranking competitors did not get there by luck. They found the keywords their audience was searching for, created content that matched that intent, and built authority over time. That work is now visible. And with the right tools and process, you can use it.
The fastest way to find competitor keywords is by analysing the terms competing websites already rank for using SEO tools like Ahrefs, Semrush, or Google Keyword Planner. This reveals which keywords drive traffic in your niche, where content gaps exist, and which ranking opportunities are realistically attainable.
This guide covers exactly how to find competitor keywords that drive results, how to identify ranking opportunities worth targeting, the tools to use, and the process we use to turn competitor research into measurable organic growth.
Let’s get into it.
TL;DR
- Competitor keyword research shows which keywords already drive traffic in your niche.
- Use tools like Semrush, Ahrefs, SpyFu, and Google Keyword Planner to uncover keyword gaps and ranking opportunities.
- Focus on keywords with achievable difficulty, clear search intent, and strong business value.
- Analyse both organic and paid competitor keywords to identify high-intent opportunities.
- Prioritise content gaps, long-tail keywords, and SERP features like AI Overviews and People Also Ask.
What Is Competitor Keyword Research?
Competitor keyword research is the process of reverse engineering the keywords your competitors are ranking for so you can identify what is working in your niche, find gaps in your own strategy, and build content that captures traffic you are currently missing.
Traditional keyword research starts from scratch: brainstorming topics, checking volumes, estimating difficulty, and guessing at intent. Competitor keyword research starts from evidence – real keywords driving real traffic to real sites in your space.
Competitor keywords are phrases and terms that your industry rivals rank for in search engine results. Identifying them allows businesses to refine their content and SEO tactics to compete more effectively for search engine visibility.
The difference in starting point is significant. When you build on competitor intelligence, every keyword you target has already demonstrated demand. Your job becomes doing it more thoroughly, more clearly, and with stronger authority signals.
Why Competitor Keyword Analysis Matters in 2026
In 2026, the SEO landscape is more competitive than it has ever been. AI-generated content has flooded the internet, Google’s ranking signals are more sophisticated, and the gap between brands that rank and those that do not is increasingly determined by the quality of their content strategy.
Tracking competitor keywords gives you early signals about where the market is heading. If multiple competitors suddenly start targeting new topics or terms, that’s your cue that something is shifting. And when you recognise those patterns early, you can adjust your strategy and be one of the first to respond.
Here is specifically what competitor keyword research helps you do:
- Find proven keywords you have not targeted yet: Terms driving traffic to competitors that are completely absent from your strategy.
- Identify content gaps: Topics where competitors are ranking but you have no content, or where your content is weaker than theirs.
- Spot where competitors outrank you: Understand where and why competitors are ranking higher, so you can close the gap strategically.
- Find commercial keywords worth bidding on: Paid keywords competitors target reveal high-intent terms worth owning organically.
- Surface long-tail opportunities: Lower-competition keywords with specific intent that competitors may be overlooking.
- Identify AI Overviews triggers: Keywords that generate SERP features (People Also Ask, AI Overviews, etc.) so you can optimise for those placements.
- Understand what is gaining momentum: Emerging keyword clusters that are rising before they become highly competitive.
From our experience at Justwords, the quickest wins in any new content programme almost always come from competitor keyword analysis. Before we write a single brief, we run a gap analysis against the top 3–5 competitors in a client’s niche. In the first audit, we typically find dozens of high-potential keywords the client is not targeting, many of which have clear ranking opportunities.
How to Identify Your Competitors for Keyword Research
Before you can analyse competitor keywords, you need to know which competitors to look at. There are two distinct types, and both matter.
- Domain-level competitors: These are brands that compete with your entire website. They operate in the same industry, serve similar audiences, and often target overlapping keyword clusters. These are the big players in your space.
- Page-level competitors: They compete with you on specific keywords or topics. A lifestyle blog might not be a business competitor at all, yet it could outrank your product page for a high-value search query. Page-level competitors are often overlooked, but they are frequently easier to beat than domain-level players.
How to Find Your Competitors?
Here’s how to identify your real search competitors:
- Using Ahrefs: Enter your domain in Site Explorer to see domain-level competitors. Enter a target keyword in Keyword Explorer to find page-level competitors ranking for that specific term.
- Using Semrush: The Organic Rankings tool shows your main organic competitors by domain. The Keyword Gap tool reveals page-level competitors for specific keyword clusters.
- Using Google Search: The most immediate method. Search your primary target keywords and note which websites consistently appear above you. Every site ranking above you for your core terms is a competitor worth analysing.
Start with 3–5 strong competitors. This is enough to identify clear patterns without overwhelming your analysis. For most niches, the top 3 organic competitors for your two or three most important keywords will give you more than enough data to work with.
5 Key Factors in Competitor Keyword Analysis
Before adding a keyword to your strategy, evaluate it against these 5 factors:
1. Search Volume
Search volume tells you how many monthly searches a keyword receives on average. Higher volume means more potential traffic, but also, typically, more competition.
The mistake most people make is chasing volume at the expense of everything else. A keyword with 50,000 monthly searches and a keyword difficulty of 85 is functionally useless to a new site. A keyword with 800 monthly searches and a keyword difficulty of 20, targeted with strong content, can rank and drive qualified traffic within weeks.
Evaluate volume in context always alongside difficulty and intent.
2. Keyword Difficulty
Keyword difficulty (KD) measures how hard it will be to rank for a keyword in organic search, based on the authority of the pages currently ranking for it. Keyword difficulty scores typically range from 0 to 100, with higher numbers indicating more competitive keywords. A high difficulty score means you will face strong competition from established websites, while a low score represents an opportunity to rank more easily.
For most content programmes, the sweet spot is keywords with reasonable search volume and a difficulty score that is attainable for your current domain authority. Target keywords with lower difficulty scores, typically under 50, to gain quick wins and establish relevance and authority before gradually targeting more competitive terms.
3. Search Intent
Search intent is the single most important factor in keyword evaluation and the most frequently underestimated.
Every keyword reflects an underlying purpose. Users searching a keyword want one of four things: information (informational intent), navigation to a specific site (navigational), a comparison or evaluation (commercial), or a purchase (transactional). A keyword with perfect volume and low difficulty is worthless if your content does not match what the searcher actually wants.
When evaluating competitor keywords, look at the pages currently ranking: what format are they? What do they cover? What does the searcher clearly want? Your content must serve that intent better than anything currently on page 1.
4. User Engagement Metrics
Competitor keyword research lets you see which queries are driving the most clicks and engagement, revealing the questions your audience is asking and what they are trying to accomplish.
Look beyond rankings to understand how users interact with the content ranking for a keyword. High bounce rates on competitor pages signal that existing content is not satisfying intent – an opportunity for you to do it better. Strong time-on-page signals that the format and depth are working – useful guidance for your own content approach.
5. SERP Features and AI Visibility
In 2026, ranking position is no longer the only measure of keyword opportunity. Google’s SERP is increasingly populated with features that appear above traditional organic results: AI Overviews, People Also Ask boxes, knowledge panels, and image packs.
When evaluating competitor keywords, note which SERP features are triggered. A keyword that triggers an AI Overview is an AEO opportunity: structure your content to directly answer the query and you may be cited even without ranking in the top 3 organic positions.
How to Find Competitor Keywords: A 5-Step Process
Here’s the step-by-step process to find competitive keywords effectively:
Step 1: Gather Your Resources
Before you start, assemble the following:
- Your shortlist of 3–5 competitors (domain and page-level).
- A chosen keyword research tool (see recommendations below).
- A spreadsheet or analysis template to organise your findings.
- Your own current keyword rankings (export from Google Search Console).
Having your own rankings data is essential. You need it to identify genuine gaps, not just keywords your competitors rank for that you also rank for.
Step 2: Run Your Competitors Through Your Keyword Tool
Enter each competitor’s domain into your chosen tool and export their organic keyword data. Depending on the tool, you will be able to see:
- Every keyword the domain ranks for organically.
- The ranking position for each keyword.
- The estimated monthly traffic each keyword drives.
- Keyword difficulty and search volume.
- The specific page ranking for each keyword.
Do this for each competitor and pull the data into your spreadsheet.
Step 3: Run a Keyword Gap Analysis
A keyword gap analysis compares your keyword rankings against your competitors’ to reveal keywords they rank for that you do not. This is where the most actionable opportunities live.
Keyword gap analysis is an SEO method that helps you discover keywords your competitors rank for while you do not. By comparing keywords side by side, you can uncover hidden opportunities and capture relevant organic traffic from competing SERPs.
Most major tools (Semrush, Ahrefs, KWFinder) have a dedicated keyword gap feature. Enter your domain and 2–4 competitors simultaneously, and the tool will surface the keywords they rank for that you are missing entirely.
Step 4: Evaluate and Prioritise
You must first identify the keyword gaps that are worth closing immediately. Filter your list using the 5 factors above (volume, difficulty, intent, engagement signals, and SERP features), and assign a priority level to each opportunity.
A useful prioritisation framework looks like this:
| Priority | Criteria |
| High | Clear intent match, achievable difficulty, meaningful volume, SERP feature opportunity |
| Medium | Good intent fit, moderate difficulty, solid volume, no SERP features currently |
| Low | Relevant but high difficulty, low volume, or intent mismatch with your content |
Focus your immediate content efforts on high-priority gaps. Plan medium-priority keywords into your content calendar. Set low-priority keywords aside for review in 6 months when your authority may have grown.
Step 5: Build and Monitor
Create content targeting your priority keywords or update existing content to capture keyword gaps where you already have relevant pages. Then track your rankings for those keywords monthly to measure progress and adapt.
Improving your SEO with competitor keywords requires a strategic approach: conduct a thorough analysis to identify what terms significant players are ranking for, perform a content audit to pinpoint gaps, and continuously evolve your approach based on updated competitor insights.
Competitor keyword research is not a one-off exercise. Competitors update their content, target new keywords, and build new pages continuously. Build a quarterly review into your SEO workflow to stay current.
The Best Competitor Keyword Analysis Tools in 2026
1. Semrush
Semrush is the most comprehensive all-in-one SEO and marketing platform available for competitor keyword analysis. Its Keyword Gap tool lets you compare several competitors side by side to spot overlapping and exclusive keywords. Position Tracking displays how keywords rank over time against competitors, and the Competitors Dashboard offers a quick look at the main competitors and their share of traffic in the niche.
Semrush’s keyword database covers 25+ billion keywords with detailed metrics, competitor keyword analysis, search intent analysis, and SERP feature tracking, making it the most data-rich option for serious competitor analysis.
Best for: Full-service competitor keyword research, keyword gap analysis, and ongoing competitive monitoring.
2. Ahrefs
Ahrefs has a robust competitor keyword research tool that lets you identify content gaps, look at multiple competitors simultaneously, and find keywords you should be targeting. Its Site Explorer tool is particularly strong for understanding which pages are driving the most traffic for competitor domains, giving you insight into not just which keywords to target but what content formats are working.
Ahrefs is also the industry standard for backlink analysis, which makes it useful for understanding why competitors rank for the keywords they do and what authority-building work might be required to compete.
Best for: Deep competitor analysis, content gap identification, and backlink research.
3. SpyFu
SpyFu is built specifically for competitive intelligence, particularly for uncovering competitors’ paid keyword strategies. SpyFu previewed competitor ad activity in a way that most tools do not match. Entering a competitor URL gives you a full view of the keywords they have bid on historically, their best-performing ad copy, and the organic keywords they rank for but you do not.
If paid search competitive analysis is part of your research (and it should be – paid keywords reveal high-intent terms worth targeting organically), SpyFu is the best tool for the job.
Best for: Paid keyword competitive analysis, PPC strategy, and identifying high-intent organic opportunities from competitor ad data.
4. Google Keyword Planner
Free, reliable, and frequently underused for competitor research. Log in to your Google Ads account, navigate to Keyword Planner, and enter a competitor’s URL instead of a keyword phrase. Google will generate keyword ideas based on the content of that URL, giving you a window into the terms Google associates with their site.
It is less comprehensive than paid tools and does not show competitor ranking positions, but for businesses starting out or working with limited budgets, it provides genuinely useful competitive keyword data at no cost.
Best for: Budget-conscious competitor keyword research (free with a Google Ads account); supplementing paid tool data.
5. Moz Pro
Moz’s Keyword Explorer tool offers keyword volume ranges, difficulty scores, and related keyword suggestions. The Link Explorer gives insight into where competitors are earning links, and Competitive Research and Domain Analysis provide snapshots of top-ranking pages, authority metrics, and keyword visibility.
Moz Pro is particularly well-regarded for its domain authority metric and its clean, accessible interface. This makes it a practical choice for teams that need competitor keyword insights without a steep learning curve.
Best for: Keyword research with authority context; teams newer to SEO tooling.
6. Ubersuggest
Ubersuggest offers a cost-effective entry point for competitor keyword research. Running a competitor’s domain through Ubersuggest’s Domain Overview tool shows estimated traffic, top keywords, and a preview of their backlinks. It’s not as detailed as paid platforms, but enough to understand which pages are driving their traffic. Keyword Overview and Keyword Suggestions give search volume, CPC, and SEO difficulty data plus related keyword ideas.
Best for: Small businesses and solo marketers who need competitor keyword data without enterprise-level pricing.
7. BuzzSumo
BuzzSumo approaches competitor research from a content and social angle rather than a pure keyword angle, making it a strong complement to the tools above. Its Content Analyzer feature shows you how your content compares to competitors’ in terms of social shares, content type, engagement, and keyword coverage.
Use BuzzSumo alongside a keyword-focused tool like Semrush or Ahrefs to understand not just which keywords competitors rank for, but which of their content assets are generating the most engagement and backlinks.
Best for: Content gap analysis, identifying high-performing competitor content formats, and social engagement intelligence.
Stacking Free Tools for Maximum Coverage
The best results from free tools come from stacking them, since each free plan has limits. Semrush uncovers keyword gaps, SpyFu previews competitor ad activity, and Similarweb shows traffic sources. Combined, they give a fuller picture of competitor strategies, even if the free versions only offer partial access.
If budget is a constraint, the combination of Google Keyword Planner (URL-based research), Semrush free plan (keyword gap), SpyFu free plan (paid keyword intelligence), and Ubersuggest (domain overview) will cover most bases without any paid subscription.
8 Best Practices to Maximise Your Competitor Keyword Analysis
Finding competitor keywords is only half the work. How you act on the data determines whether you see actual results.
1. Prioritise keywords where searcher intent is not well served:
Look for competitor keywords where the top-ranking content is thin, outdated, or mismatched to the query. These are your easiest wins. You do not need to build more authority than the current ranking page; just produce better content.
2. Target long-tail keywords around high-difficulty head terms:
If a direct competitor ranks for a high-difficulty keyword you cannot currently compete for, look for long-tail variants around the same topic. These related queries are often less competitive, carry more specific intent, and can drive highly qualified traffic.
3. Build topical clusters, not isolated pages:
When you find a keyword gap, do not just create one page. Build a content cluster – a pillar page targeting the main keyword, supported by related pages addressing subtopics and long-tail variants. This approach builds topical authority faster than isolated articles.
4. Turn competitor paid keywords into organic targets:
The keywords competitors are spending money on in Google Ads are high-value, high-intent terms. If you can rank organically for those keywords, you capture the same traffic without the ongoing cost. Paid keyword data is one of the most underused sources of organic keyword intelligence.
5. Watch for seasonal and trend-driven keywords:
Competitor keyword rankings shift with trends and seasons. Set up monitoring for key competitor URLs so you are alerted when they publish new content or start ranking for new terms. Early awareness of a rising keyword lets you move before it becomes competitive.
6. Target bottom-of-funnel keywords for conversion impact:
Informational keywords drive awareness; transactional and commercial keywords drive revenue. Identify the bottom-of-funnel terms your competitors rank for (product comparisons, “best of” lists, service-specific terms) and prioritise them alongside your awareness content.
7. Track SERP features and AEO opportunities:
For every keyword you target, note whether Google is serving an AI Overview, featured snippet, or People Also Ask box. Structure your content specifically to capture these placements. They can generate visibility and clicks even when you do not rank in position 1.
8. Make competitor keyword analysis a recurring discipline:
Quarterly reviews are the minimum. In fast-moving niches like technology, marketing, finance, and e-commerce, monthly competitive audits are worth the time investment. Competitor strategies shift, new competitors emerge, and Google’s rankings update constantly. Your keyword intelligence is only as useful as it is current.
Final Thoughts
Competitor keyword research is not a project you complete once and file away. It is an ongoing intelligence practice – one that gives you a continuous window into what is working in your niche, where the opportunities are, and how the competitive landscape is shifting.
The brands that consistently win in organic search are the ones that treat competitive intelligence as a standard part of their SEO workflow. They know which keywords they are missing. They know what their competitors are publishing next. And they act on that knowledge systematically.
Use the tools, follow the process, and make it a rhythm. The data will tell you exactly where to focus. And that focus is what separates content that ranks from content that gets lost.

FAQs
1. What is the best way to find competitor keywords?
The most effective approach is to use a dedicated competitor keyword analysis tool like Semrush, Ahrefs, or SpyFu, to enter a competitor’s domain and see every keyword they rank for organically. From there, run a keyword gap analysis to identify which of those keywords you are not currently targeting. Supplement with Google Keyword Planner (enter a competitor’s URL instead of a keyword) for additional ideas, and Google Search for quick manual verification.
2. How do I check competitor keywords for free?
Google Keyword Planner is the most accessible free option. Log in with a Google Ads account, enter a competitor’s URL, and generate keyword ideas based on their site content. Semrush, Ahrefs, Ubersuggest, and SpyFu all offer free plans with limited queries that can provide useful data without a paid subscription. Stacking multiple free tools gives broader coverage than relying on any single one.
3. What is keyword gap analysis?
Keyword gap analysis is the process of comparing your keyword rankings against your competitors’ to identify terms they rank for that you currently do not. It is the core output of competitor keyword research – the list of high-potential keywords that represent your most direct organic growth opportunities. Most major SEO tools have a dedicated keyword gap feature that automates this comparison.
4. How do I know which competitor keywords are worth targeting?
Evaluate each keyword against five criteria: search volume (is there meaningful demand?), keyword difficulty (is ranking achievable given your current authority?), search intent (does the keyword match what you can produce?), user engagement signals (is existing content serving the searcher well?), and SERP features (are there AI Overviews to capture?). Keywords that score well across all five are your highest-priority targets.
5. What is the difference between domain and page-level competitors?
Domain-level competitors are websites that compete with you across your entire keyword footprint – they operate in the same space and target similar audiences broadly. Page-level competitors only compete with you on specific keywords – a single blog post from a publication outside your industry might outrank your page for one high-value term without competing on anything else. Both types are worth analysing; page-level competitors are often easier wins because the overall domain may have lower authority than yours.
6. How often should I perform competitor keyword analysis?
For most businesses, quarterly analysis is the minimum. Fast-moving niches like technology, digital marketing, fashion, and finance require monthly reviews. Competitor strategies shift, new players enter the market, and Google’s rankings update constantly. The brands that stay ahead competitively are the ones treating keyword intelligence as a continuous process, not a one-off exercise.
7.Can I use competitor keyword data for paid search?
Absolutely. It is one of the most valuable applications of the data. The keywords competitors are bidding on in Google Ads are high-intent terms with proven commercial value. Use tools like SpyFu to see exactly which paid keywords competitors are targeting, what they are paying per click, and which ad copy is performing. This intelligence informs both your paid strategy and your organic content priorities.
8. What should I do once I have found my competitor keywords?
Prioritise your keyword gap list by difficulty, intent fit, and strategic value. Create new content targeting your highest-priority gaps, or update existing content to capture terms where you have a relevant page but weak ranking. Build topical clusters rather than isolated pages. Set up rank tracking to monitor progress. And schedule a recurring review to update your analysis as the competitive landscape evolves.
