If you want to outrank rivals, start by learning how to see what keywords your competitors are using. This guide shows you exactly how to find competitor keywords, free and paid options, how to check competitors’ keywords ethically, and how to prioritize what to target next. For broader context and a complete framework, see our SEO competitive analysis guide.
SEO competitors vs. business rivals
Your business rivals are the companies you pitch against in sales. Your SEO competitors are the domains that outrank you in the SERPs for your target queries. These two groups overlap but are rarely identical. For example, a niche blog might outrank your SaaS site for comparison queries, while a marketplace page dominates your product keyword even though you do not compete commercially.
Why this matters: you should extract competitor keywords from whoever owns the SERP, not just from brands you recognize. Here is a practical way to identify true SEO competitors:
As a first step in competitor analysis, focus on the domains that consistently own the SERP for your seed topics.
- Start with seed topics – list 10 to 20 core terms customers use.
- Scan the SERP – note the recurring domains in positions 1 to 10. Include publishers, marketplaces, and aggregators.
- Cluster by intent – group domains by informational, commercial, transactional, and local intent to understand who competes where.
- Prioritize by overlap – if a domain appears across multiple clusters, they are a prime SEO competitor.
To structure your review, see competitor profiling: what to include.
InSpace.io speeds this up with real-time SERP reconnaissance, continuously mapping which domains gain or lose visibility across your topic clusters so you always target the right rivals.
Ways to find competitor keywords
There are three reliable routes. For breadth, use organic rankings data to see all keywords a competitor ranks for. For speed, run a keyword gap analysis across several competitors to surface missing or untapped opportunities. For high intent, mine paid keywords to discover converting queries competitors buy. Dedicated competitive analysis features can streamline these workflows.
Free manual checks
If you need to check competitors’ keywords for free, manual SERP and page analysis still works. Pick a keyword, open the top 5 results, then review:
- Title, H1, H2 – recurring phrases often reflect primary and secondary keywords.
- URL slugs – short slugs hint at head terms; long slugs reveal long-tail angles.
- Internal links – anchor text surfaces related topics and synonyms.
- FAQ schema – questions reveal supporting keywords and subtopics.
Limitations: it is slow, biased to a handful of pages, and misses hidden or low-volume long-tail terms. Use it to sanity-check your findings or when you need to find a competitor’s keywords without tools. A structured set of competitive analysis questions to ask keeps your review objective. If you want to accelerate parts of this workflow with automation, you can use AI for keyword research.
Find a single competitor’s keywords
To see what keywords your competitors are using at scale, pull their organic ranking keywords:
- Enter the competitor domain or URL in your analysis tool.
- Filter for your target market and language.
- Sort by traffic, position, and intent to spot their top-value pages.
- Export keywords for pages that mirror your products, categories, and key articles.
For a complete walkthrough, conduct a competitive analysis step-by-step.
Prioritize terms where your site is absent or sits outside the top 20, especially keywords with mid to high intent and realistic difficulty. InSpace.io’s competitive keyword scan highlights the exact pages and queries that drive leads for your rivals, including the percent of traffic and recent position shifts so you can jump on decaying content or rising trends. Pair this with competitor profiling to capture messaging, target keywords, and page types for each rival.
Compare multiple competitors with keyword gap
A keyword gap compares what your competitors rank for against your coverage. This reveals two high-yield sets:
- Missing – competitors rank, you do not. Build targeted pages or expand existing content.
- Untapped – some competitors rank, others do not. Great for quick wins where the SERP is less consolidated.
How to run it:
- Select 3 to 5 competitors representing the SERP: a publisher, a marketplace, and direct peers.
- Run the gap analysis and filter by intent, difficulty, and volume ranges that match your resources.
- Group results by topic and assign each topic to a content format: guide, comparison, checklist, category page, or product page.
InSpace.io automates gap clustering and produces an execution-ready backlog with content briefs, internal link targets, and projected traffic opportunity. Use a competitive profile matrix to score rivals and expose keyword themes where you can win.
Find competitors’ paid keywords
To find out what keywords competitors are using in ads, inspect their paid search footprint:
- Capture ad keywords – pull paid queries by domain and country. Look for consistent head terms across months.
- Match ad copy to intent – note CTAs and value props tied to keywords with high CPC or impression share.
- Cross-check with landing pages – confirm the mapped intent and conversion flow. If they spend on it, it likely converts.
Practical uses:
- Build a high-intent cluster – add these to your SEO plan and to your own PPC for coverage.
- Exclude waste – find irrelevant brand or broad matches they avoid and add them as negatives.
- Auction insights – watch overlap rate and top-of-page rate to calibrate bids.
InSpace’s advertising intelligence flags the keywords your rivals buy, their landing pages, and volatility in spend so you can react in real time.
How to choose and use competitor keywords
Finding keywords is easy. Winning with them requires evaluating fit, difficulty, and impact, then choosing the right content or campaign play. Start with the metrics that matter most, then map each target to the right page type and internal links.
Evaluate potential keywords
Use the following metrics to judge whether to pursue a keyword for SEO, PPC, or both. Combine them rather than relying on a single score.
| Metric | What it measures | Use in SEO | Use in PPC |
|---|---|---|---|
| Search volume | Average monthly demand | Helps size traffic, but validate with topic breadth | Forecasts spend and reach |
| Keyword difficulty | Estimated effort to rank | Gauge link and content needs | Irrelevant |
| SERP intent | Informational, commercial, transactional, local | Pick the right format and CTA | Align ad type and offer |
| CTR curve | Clickability based on SERP features | Adjust expectations if ads, maps, or snippets dominate | Higher ad density can justify bids |
| Top pages’ authority | Link and topical strength of ranking pages | Signals required authority or internal links | Suggests landing page trust signals |
| CPC | Average cost per click | Proxy for commercial value | Budget planning |
| Position volatility | How often rankings change | Good for agile content to capture swings | Spot seasonal bid windows |
Decision rule of thumb: target keywords with clear intent, realistic difficulty relative to your domain strength, and a path to revenue. InSpace.io enriches each keyword with real-time volatility, intent, and page-level insights so you can prioritize by impact, not guesswork.

High vs. low competition keywords
Low-competition keywords are ideal for fast wins, especially long-tail phrases like how to check competitor website keywords or how to find keywords of competitors website. They need less authority and often convert better due to specific intent. High-competition head terms can be worth the investment if they map directly to core revenue pages, but plan a phased approach: publish a best-in-class asset, build internal links, then layer supporting content and outreach.
Fill content gaps and long-tail opportunities
Content gaps are keywords your competitors rank for and you do not. Long-tail alternatives are the 3 to 6 word variants with lower volume but higher conversion, such as how do I find my competitors’ keywords for free or how to check competition on a keyword. Tackle gaps with focused pages that precisely satisfy intent, and expand with clusters of long-tail subtopics using FAQs, comparisons, and checklists. InSpace.io’s content gap mapping generates topic clusters with briefs and internal link targets so you can ship quickly.
Build topical authority
Topical authority grows when you cover a subject comprehensively and connect pages logically. Create a hub for your core problem, link to detailed guides and comparisons, and keep everything updated. Use internal links from high-authority pages to give new pages a lift, and add structured data where relevant to win rich results.
Track and refine
Once you deploy, track rankings, traffic, and conversions by keyword and page. Monitor competitors’ movement to catch content decay, new entrants, or SERP feature changes. Practical actions:
- Position tracking – monitor your targets vs. 3 to 5 key competitors by device and location.
- Change alerts – get notified when rivals publish or gain links on overlapping topics.
- Iterate – update pages when intent shifts or competitors introduce new angles.
InSpace.io adds real-time competitive tracking that surfaces sudden gains or losses so you can respond before impact compounds.
