How to Find Your Competitors’ Keywords

To find your competitors’ keywords, first identify who your actual search competitors are (the sites ranking for your target terms, which aren’t always your business rivals), then use keyword-research tools to see the terms they rank for, run a keyword-gap analysis to find terms they rank for and you don’t, and mine their top pages and the live SERPs. Finally, filter what you find by winnability — target the gaps you can realistically rank for. Here’s how.

This guide covers identifying competitors, pulling their keywords, and filtering to the winnable gaps.

Step 1 — Identify your real search competitors

Your search competitors aren’t always your business competitors. The sites you’re competing with in search are whoever ranks for the terms you want — which might include publishers, directories, or businesses you’d never think of as rivals. Find them by searching your core target keywords and noting who consistently ranks on page one. Those are the sites whose keywords are worth studying.

Step 2 — Use keyword-research tools

Tools like Ahrefs, Semrush, and similar let you enter a competitor’s domain and see the keywords they rank for, along with volume and difficulty. This is the fastest way to get a broad picture of a competitor’s keyword footprint. Look at:

• Their top organic keywords (what drives their traffic).
• Keywords where they rank but you don’t.
• The intent behind those keywords.

Step 3 — Run a keyword-gap analysis

Most tools offer a keyword gap (or “content gap”) feature: enter your domain and a few competitors, and it shows keywords they rank for that you don’t. This is the highest-value output — it surfaces the specific opportunities you’re missing. These gaps are your candidate targets.

Step 4 — Mine their top content and structure

Beyond tools, study competitors’ actual pages:

• Look at their best-performing pages — what topics and questions do they cover?
• Note the subtopics and questions within those pages (often revealing long-tail terms).
• Check their internal structure — clusters and pillars reveal how they organize a topic.

This qualitative mining catches intent and topic angles that raw keyword lists miss.

Step 5 — Read the live SERPs

For any promising keyword, search it yourself and study the results: who ranks, how strong they are, what format Google rewards, and what related terms appear in People Also Ask and related searches. The live SERP is free, current competitive intelligence that confirms intent and difficulty.

Step 6 — Filter by winnability (don’t just copy)

This is the step that separates useful competitive research from wasted effort: don’t just target everything a competitor ranks for. A big competitor may rank for terms far beyond your site’s current authority. Filter your gap list by winnability — check keyword difficulty and the actual SERP strength — and prioritize terms you can realistically rank for. Winnable gaps beat impressive-but-impossible ones.

Step 7 — Map and act on the gaps

Turn your filtered, winnable gaps into a content plan: assign each to a single page (avoiding cannibalization), and create content that’s genuinely better than the competitor’s — more thorough, better intent match, answer-first. Finding the keyword is step one; out-executing on it is what earns the ranking. (SEO consulting turns competitor keyword gaps into a winnable content plan — or run a free website audit.)

Frequently asked questions

How do I find my competitors’ keywords? Identify your real search competitors (the sites actually ranking for your target terms), then use keyword-research tools like Ahrefs or Semrush to see the keywords they rank for. Run a keyword-gap analysis to find terms they rank for and you don’t, mine their top pages for subtopics, and read the live search results. Finally, filter the gaps by winnability and target the ones you can realistically rank for.

What tools show competitor keywords? Tools like Ahrefs, Semrush, and similar SEO platforms let you enter a competitor’s domain and see the organic keywords they rank for, along with search volume and difficulty. They also offer keyword-gap or content-gap features that compare your site to competitors and reveal terms they rank for that you don’t. These paid tools are the fastest way to get a broad, data-backed view of a competitor’s keyword footprint.

Who are my search competitors? Your search competitors are whoever ranks for the keywords you want to target — which aren’t always your direct business rivals. They can include publishers, directories, review sites, or businesses outside your usual competitive set. To identify them, search your core target keywords and note which sites consistently appear on page one; those are the sites whose keyword strategies are worth studying.

What is a keyword gap analysis? A keyword gap analysis compares your site to one or more competitors and shows the keywords they rank for that you don’t. Most SEO tools offer this as a gap or content-gap feature. It’s one of the highest-value outputs of competitor research because it directly surfaces the specific opportunities you’re missing, giving you a targeted list of candidate keywords to pursue rather than guessing.

Should I target all the keywords my competitors rank for? No. A larger or more established competitor may rank for terms far beyond your site’s current authority, so blindly copying their entire keyword list wastes effort on unwinnable targets. Instead, filter the gaps by winnability — checking keyword difficulty and the actual strength of the current search results — and prioritize terms you can realistically rank for. Winnable gaps produce results; impossible ones don’t.

Can I find competitor keywords for free? Partly. Reading the live search results for your target terms — seeing who ranks, studying their pages, and noting People Also Ask and related searches — is free competitive intelligence. Google’s Keyword Planner offers some free data too. However, comprehensive competitor keyword data and gap analysis generally require paid tools like Ahrefs or Semrush, which show the full picture of what competitors rank for.

How do I use competitor keywords to rank? Filter competitor keywords to the winnable gaps, map each to a single page to avoid cannibalization, and then create content that’s genuinely better than the competitor’s ranking page — more thorough, a stronger intent match, and answer-first structured. Finding the keyword is only the start; you rank by out-executing the current results, not just by targeting the same term the competitor uses.
