How to Steal Your Competitor’s Best Keywords with Semrush

Key Takeaways

• Competitor keyword research should be ethical, strategic, and value-driven.
• Semrush Organic Research helps reveal competitor keywords and top pages.
• Semrush Keyword Gap helps compare your domain against competitors.
• The best tabs to review are usually Missing, Weak, and Untapped keywords.
• Keyword Magic Tool helps expand competitor topics into long-tail opportunities.
• Do not copy competitor pages. Instead, build better pages that answer search intent more completely.
• Therefore, the real win is not stealing keywords. It is stealing market attention with better content.

What “Stealing Keywords” Really Means

First, let’s be clear. You are not stealing private data. You are researching public search visibility. Your competitors rank for keywords in Google. Therefore, you can study those rankings and decide where your website should compete.

However, ethical competitor keyword research does not mean copying their articles, layouts, offers, or brand voice. Instead, it means identifying market demand and creating a better answer.

For example, if a competitor ranks for “technical SEO audit checklist,” you should not rewrite their article with different wording. Instead, you should create a stronger checklist, add better examples, include schema, include screenshots or process steps if possible, and connect the page to your own services or affiliate strategy.

Google’s SEO Starter Guide explains that SEO helps search engines understand content and helps users find your site. Therefore, the best way to compete is to create genuinely helpful content that satisfies search intent better than the current results. Google SEO Starter Guide

Consequently, “stealing keywords” should really mean “finding proven demand and serving it better.”

Why Semrush Works for Competitor Keyword Research

Semrush works well because it gives you several ways to uncover competitor keyword opportunities. Additionally, it connects keyword data to traffic estimates, keyword difficulty, CPC, intent, SERP features, and ranking pages.

Use these core tools:

• Organic Research: Find competitor rankings, top keywords, and top pages.
• Keyword Gap: Compare your domain against competitors and find missing or weak keywords.
• Keyword Magic Tool: Expand competitor topics into long-tail opportunities.
• Position Tracking: Track your progress after publishing.
• Site Audit: Make sure technical issues are not blocking growth.

Semrush’s Keyword Gap tool can compare your site with up to four competitors and identify missing opportunities. Additionally, Semrush’s 2026 keyword research guidance specifically highlights Missing and Weak keywords as high-value places to focus. Semrush keyword research framework

Step 1: Build Your Competitor List

Before opening reports, choose the right competitors. This step matters because many businesses compare themselves to the wrong sites.

You need three types of competitors:

1. Direct Business Competitors

These companies sell similar products or services. For example, an SEO agency may compare against other SEO agencies.

2. Search Competitors

These websites rank for the same keywords, even if they do not sell the same thing. For example, blogs, directories, review sites, and media companies may compete for search visibility.

3. Aspirational Competitors

These are stronger sites you want to eventually compete with. However, do not only study huge brands. Otherwise, your keyword list may become unrealistic.

Competitor Selection Checklist

• Do they rank for keywords you want?
• Do they sell to your audience?
• Do they publish similar content?
• Do they target your service areas?
• Do they have realistic authority compared to your site?
• Do they get traffic from topics you should own?

After that, choose three to five competitors for the first analysis.

Step 2: Use Organic Research to Find Top Keywords

Next, enter a competitor domain into Semrush Organic Research. This helps reveal which keywords drive visibility for that competitor.

What to Review

• Top organic keywords
• Estimated traffic by keyword
• Current ranking position
• Search volume
• Keyword difficulty
• CPC
• Ranking URL
• Top organic pages

Then, export the best opportunities into a spreadsheet. However, do not export everything blindly. Instead, focus on keywords that match your audience, services, content strategy, or affiliate model.

Actionable Filter

Start with keywords where the competitor ranks between positions 1 and 20. These terms already show that the topic has value. Additionally, look for keywords with clear commercial or informational intent.

For example, if a competitor ranks for “Semrush vs Ubersuggest,” that keyword may support an affiliate comparison article. If they rank for “technical SEO audit service,” that keyword may support a service page.

Step 3: Use Keyword Gap to Find Missing Keywords

After reviewing one competitor, use Keyword Gap. This is where the real opportunities appear.

Enter your domain and up to four competitor domains. Then review the keyword overlap. Semrush’s Keyword Gap tool shows common and unique keywords across compared sites. Semrush Keyword Gap

Focus on Missing Keywords

Missing keywords are keywords your competitors rank for but your website does not. Therefore, these are often the fastest content planning opportunities.

What to Look For

• High-intent service keywords
• Comparison keywords
• Question keywords
• Buyer guide keywords
• Local service keywords
• Product review keywords
• Long-tail informational keywords

Actionable Tip

Sort missing keywords by intent first, not volume. A low-volume keyword with commercial intent can be more valuable than a high-volume keyword with vague intent.

Step 4: Find Weak Keywords You Can Improve

Missing keywords show where you have no visibility. However, Weak keywords may be even more valuable. These are terms where you already rank, but competitors rank higher.

Because you already have some visibility, you may not need a brand-new page. Instead, you may need to improve the existing page.

How to Improve Weak Keywords

• Rewrite the title tag.
• Add a clearer direct answer.
• Expand thin sections.
• Add FAQs.
• Add internal links.
• Update outdated information.
• Add comparison tables.
• Improve page speed.
• Add schema.
• Strengthen the CTA.

Therefore, Weak keywords are useful because they often require optimization, not total creation.

Example

If your page ranks position 11 for “how to use Semrush for keyword research,” and a competitor ranks position 3, inspect what their page does better. Then improve your page with stronger steps, better examples, more internal links, and clearer FAQs.

Step 5: Expand Winners With Keyword Magic Tool

After identifying a strong competitor keyword, open Keyword Magic Tool. This helps you turn one keyword into a full cluster.

How to Expand a Competitor Keyword

1. Enter the competitor keyword.
2. Review related terms.
3. Use question filters.
4. Filter by lower difficulty.
5. Check commercial intent.
6. Group similar terms.
7. Choose one primary keyword per page.
8. Save supporting keywords for sections and FAQs.

Example Cluster

Primary keyword: “competitor keyword research”

• how to do competitor keyword research
• competitor keyword analysis
• keyword gap analysis
• find competitors keywords
• Semrush competitor keywords
• SEO competitor analysis tool

As a result, one competitor keyword becomes a full content plan.

Step 6: Sort Keywords by Intent and Value

Not every competitor keyword deserves your attention. Therefore, sort the list by intent and value before creating content.

Keyword Intent Types

• Informational: The user wants to learn.
• Commercial: The user compares options.
• Transactional: The user wants to buy or take action.
• Navigational: The user wants a specific brand.

Keyword Value Signals

• CPC
• Search volume
• Keyword difficulty
• Business relevance
• Affiliate potential
• Lead-generation value
• Ranking realism
• Internal linking fit

Additionally, ask one practical question: “If this page ranks, what business outcome can it create?”

If the answer is unclear, the keyword may not be a priority.

Step 7: Reverse-Engineer Competitor Pages

After selecting a keyword, study the page that ranks. However, do not copy it. Instead, diagnose why it wins.

Review the Competitor Page

• Page format
• Heading structure
• Search intent match
• Depth of content
• FAQs
• Internal links
• External authority links
• Schema
• Examples
• Tables or checklists
• CTA placement
• Freshness

Then identify weaknesses.

Common Competitor Weaknesses

• Thin explanations
• No actionable steps
• No schema
• No direct answer
• Outdated examples
• Weak internal links
• Generic CTAs
• No comparison table
• No original insight

Consequently, you now know how to beat the page without copying it.

Step 8: Build Better Content Than the Competitor

Better content does not simply mean longer content. Instead, it means more useful content.

How to Build a Better Page

• Answer the question directly near the top.
• Match the exact intent.
• Add clearer steps.
• Use examples.
• Include comparison tables.
• Add FAQs from real buyer questions.
• Use trusted external links.
• Add relevant internal links.
• Include schema.
• Make the CTA match the intent.

For example, if competitors write generic SEO tips, build a page with screenshots, workflow steps, checklists, and prioritization frameworks. Additionally, connect the topic to related pages on your site.

Because of that, your page becomes more valuable than the competitor’s page, not merely similar.

Step 9: Build Internal Links Around the New Page

Internal links help search engines understand how your pages connect. Therefore, do not publish a competitor-keyword page and leave it alone.

Link it from relevant existing pages. Additionally, link from the new page to related pages.

Internal Linking Checklist

• Link from related blog posts.
• Link from relevant service pages.
• Link to parent hub pages.
• Link to sibling comparison pages.
• Use descriptive anchor text.
• Avoid overusing the exact same anchor.
• Update old posts with new links.

For example, this page should naturally connect to:

• How to Use Semrush for Keyword Research
• Semrush vs. Ahrefs
• Semrush vs. Ubersuggest
• Technical SEO Audit Using Semrush
• SEO Services for Businesses

As a result, the new page joins an existing topical cluster.

Step 10: Track Rankings, Leads, and Revenue

After publishing, track performance. Otherwise, you will not know whether the competitor keyword strategy worked.

Track These Metrics

• Keyword rankings
• Impressions
• Clicks
• Click-through rate
• Average position
• Affiliate clicks
• Leads
• Sales calls
• Conversions
• Revenue
• AI visibility mentions where relevant

Use Semrush Position Tracking for keyword movement. Additionally, use Google Search Console for real impressions and clicks. For official Google guidance, review Google Search Console.

Then update the page after 30–90 days based on performance.

An affiliate site can find comparison keywords competitors already rank for, such as “Semrush vs Ubersuggest” or “best SEO tools for bloggers.” Then it can build better comparison pages with honest recommendations, tables, FAQs, and subtle affiliate links.

Local Service Business

A roofing company can find competitor city and service keywords, such as “roof repair Akron” or “metal roofing Medina.” Then it can create stronger service-area pages with local proof, FAQs, and clear CTAs.

B2B Agency

A B2B agency can find competitor industry keywords, such as “SEO for manufacturers” or “Google Ads for home services.” Then it can build industry-specific content that speaks directly to each buyer.

Ecommerce Website

An ecommerce store can find product comparison keywords, buying guide terms, and category keywords competitors rank for. Then it can improve product collections and buying guides.
