How to Find and Target Your Competitor Keywords

You check your Google Search Console and notice a competitor ranking on page one for a term you've never even tried to rank for. You click through to their page. It's not particularly good. The writing is mediocre, the page is thin, but there it sits — position four — pulling in traffic every day while your site sits on page three for something nobody searches for.

That's the moment most people go looking for competitor keywords.

The good news: this is one of the most tractable problems in SEO. Unlike link building or technical audits, competitor keyword research gives you concrete answers fast. You're not guessing what to write. You're looking at what's already working for someone else in your market and deciding which of those opportunities to take.

This guide covers the full process — how to find competitor keywords, how to evaluate them, and how to actually use them to close the gap.

What Competitor Keywords Actually Are

A competitor keyword is any keyword a competing site ranks for that either:

• You don't rank for at all, or
• You rank for significantly worse (say, they're on page one and you're on page three)

That's it. There's no magic to the term. The value is in the gap — the traffic flowing to them instead of you.

There are two types worth separating in your mind:

Content gap keywords: Terms where they have a page targeting that topic and you don't. You're missing because you haven't addressed the topic.

Ranking gap keywords: Terms where you both have pages, but theirs outranks yours. You're missing because your page isn't competitive enough.

The remedies are different. Content gaps require new pages. Ranking gaps require improving existing ones. You need to know which problem you're solving before you start.

Who Counts as a Competitor in SEO

Here's where most people go wrong at the start: they assume their SEO competitors are the same as their business competitors.

They're not always the same.

Your SEO competitors are whoever ranks for the keywords your customers use. A SaaS company that sells project management software might find itself competing in search results against:

• Direct product competitors
• Review sites like G2 or Capterra
• Productivity bloggers
• Industry publications

All of those sites are capturing search traffic your potential customers generate. Whether or not you'd call them "competitors" in a business sense, they're competitors for the search real estate you need.

So when you start this process, don't limit yourself to your business rivals. Ask: who's capturing my audience's attention in search results right now?

How to Find Your SEO Competitors

Before you can find competitor keywords, you need to know who to look at.

Method 1: Search your own core terms

Take three to five keywords you already rank for or care most about. Search them. Write down every site that appears consistently across the results. Those are your primary SEO competitors.

Method 2: Use a tool to identify them

Ahrefs, Semrush, and Moz all have competitor discovery features. In Ahrefs, go to Site Explorer → Competing Domains. In Semrush, it's Organic Research → Competitors. These tools calculate overlap between your ranking keywords and theirs.

Method 3: Ask the obvious question

What sites would your ideal customer visit when researching your category? Go to those sites. They're competitors.

Once you have a list of four to eight competitors, you're ready to pull keyword data.

How to Find Competitor Keywords

Using Paid SEO Tools

The most thorough approach uses a tool with a keyword database. Ahrefs and Semrush are the industry standards. Ubersuggest is a cheaper option with a smaller database.

The core workflow in any of these tools:

1. Enter a competitor's domain into the tool's site explorer
2. Pull their organic keywords report — this lists every keyword they rank for and their estimated position
3. Filter the results to show keywords where you don't rank in the top 20 or 30 (most tools let you filter by your own domain as an exclusion)
4. Export the list

What you get is a working list of every keyword they're capturing that you're not. Depending on the competitor, this list can run into the thousands.

For a structured approach to sorting through that list, the process for keyword competitive analysis walks through how to filter by volume, difficulty, and intent to prioritize what actually matters.

Using the Keyword Gap / Content Gap Tool

Both Ahrefs and Semrush have a specific feature for this. In Ahrefs it's called Content Gap. In Semrush it's Keyword Gap.

You enter your domain and two to four competitor domains. The tool returns keywords where your competitors rank but you don't — or where they rank significantly better.

This is faster than pulling each competitor's keywords individually. Run it, filter out low-volume noise, and you have a prioritized gap list.

Free Methods

If you're not ready to pay for a tool, you have options — they're just slower.

Google's autocomplete and related searches: Search a competitor's main topic and mine the autocomplete suggestions. These are real searches. Check which of them the competitor has addressed that you haven't.

Google Search Console comparison: You can't see a competitor's keywords directly, but you can see your own. Identify your lowest-performing queries — low impressions, low clicks — and then manually check what content your competitors have on those topics.

SpyFu free tier: SpyFu allows limited competitor keyword lookups for free. You won't get the full picture, but you can spot obvious gaps.

Checking their sitemap: A competitor's sitemap (usually at domain.com/sitemap.xml) reveals every URL they've built. Browse their blog or resource section and note topics you haven't covered.

How to Evaluate Which Competitor Keywords to Target

A raw list of competitor keywords is just a starting point. Most of the keywords on that list won't be worth pursuing. You need to filter.

Volume

Keywords with zero to ten monthly searches aren't worth dedicated pages unless you're in a very niche B2B market where a single conversion is worth thousands of dollars. For most sites, prioritize keywords with at least 100 monthly searches. For broad content strategies, focus your best effort on terms with 500 or more.

Difficulty

Keyword difficulty scores (Ahrefs uses DR, Semrush uses KD%) estimate how hard it is to rank. Lower is easier. For sites without strong domain authority, a difficulty score under 30 is where you'll find real traction. Targeting a keyword with KD 70+ when your domain is new is throwing effort into a void.

Match your targets to your current authority. If you have a new site, chase the low-difficulty wins and build from there.

Search intent

This is the most underrated filter. For each keyword, ask: what does someone actually want when they search this?

The four types:

• Informational: They want to learn ("how to do X")
• Commercial: They're evaluating options ("best X for Y")
• Transactional: They're ready to buy ("buy X online")
• Navigational: They're looking for a specific site

The intent has to match what your site can deliver. If you run an e-commerce store and a competitor ranks for an informational term, you can potentially target it with a blog post — but only if you can actually serve that informational intent well. Don't write a product page targeting a how-to keyword. It won't rank and it won't convert.

Business relevance

Some keywords your competitors rank for are simply not relevant to you. A project management tool competitor might rank for "free spreadsheet templates." That traffic isn't their target customer either — it's just adjacent content they're capturing. If it doesn't lead toward a conversion for you, deprioritize it.

How to Actually Target a Competitor's Keyword

Finding the keyword is thirty percent of the work. The other seventy is producing something better than what's ranking.

Study what's already ranking

Before you write a word, look at the top three to five results for your target keyword. Ask:

• What format is ranking? (list post, how-to guide, product page, comparison)
• How long are the pages? (word count isn't the goal, but it signals depth)
• What subtopics do they cover?
• What are they missing?

Your job is not to copy the competitor. Your job is to understand why their page ranks and then build something that covers the same ground with more depth, more accuracy, or a clearly better user experience.

Match intent precisely

If the keyword is informational, write a guide. If it's commercial, write a comparison or roundup. If it's transactional, build a product or service page. Mismatching intent is why good content sometimes fails to rank — Google can tell what people want when they search a term, and it filters out pages that don't deliver it.

Target the full keyword cluster, not just the head term

When you build a page for a competitor keyword, you're rarely targeting just one phrase. Related terms, long-tail variations, and semantically related questions should all appear naturally in your content.

For example, if you're targeting "project management software for small teams," your page should also naturally address terms like "affordable project management tools," "team task management," and "project tracking for startups." You capture the main keyword and the surrounding cluster.

For a complete breakdown of how to find and use these clusters, competitor keyword research covers the full gap-identification process with examples.

Build the page, then promote it

Publishing the page is not enough. A new page starts with no authority. You need internal links from your existing pages pointing to it. You may need external links from other sites over time. At minimum, make sure it's indexed and that you've linked to it from relevant existing pages on your site.

Building a Systematic Competitor Keyword Strategy

One-off keyword targeting doesn't compound. A real strategy runs on a repeatable process.

Here's a simple quarterly cadence:

1. Pull your gap list every quarter. Competitor keyword sets shift — they publish new content, they drop rankings, new competitors emerge. Run a fresh content gap report every three months.

2. Score and prioritize your opportunities by volume, difficulty, and business relevance.

3. Assign page types to each target keyword before writing anything. Know whether you're building a guide, a comparison, a landing page, or a product update.

4. Create and publish in batches, not as one-offs. Producing ten pages around a topic cluster does more for your authority in that area than ten scattered individual pages.

5. Track and revisit. Check your rankings on target keywords sixty to ninety days after publishing. Pages that aren't moving may need more internal links, more depth, or a restructure.

This kind of structured keyword research competitor analysis turns a one-time task into an ongoing content engine.

Common Mistakes to Avoid

Targeting keywords that are too competitive too soon: Match your domain authority to the difficulty of what you target. Trying to rank for head terms against established competitors with a new domain is a waste of resources.

Ignoring the intent: You can have the highest-quality post on a topic, but if it doesn't match what searchers actually want, it won't rank. Check the SERP before you write.

Chasing volume without checking relevance: A keyword with 10,000 monthly searches is useless if the people searching it aren't your potential customers.

Not tracking results: Many people do competitor keyword research, publish content, and never check whether it worked. You need to know what's ranking so you can double down on what works and fix what doesn't.

Treating it as a one-time project: Competitors keep publishing. Rankings shift. This is a continuous process, not a box to check.

FAQ

How many competitors should I analyze?

Four to six is a practical number. Analyze your top two or three direct business competitors plus one or two SEO-specific competitors (sites ranking for your terms that aren't direct business rivals). Beyond six, the returns diminish and the list becomes unmanageable.

How do I find competitor keywords for free?

Manually: search your topic on Google, study who ranks, visit their sitemap, and read their content to spot topics you haven't covered. Use SpyFu's free tier for limited keyword lookups. Use Google Search Console to find your own weak spots and then check competitor coverage on those topics.

How long does it take to rank for a competitor's keyword?

Typically three to six months for low-competition keywords on sites with some established authority. Higher competition terms on newer domains can take twelve months or more. There's no reliable shortcut — the variable you can control is the quality of the page you build and the internal links pointing to it.

Should I target the exact keywords my competitor ranks for, or similar ones?

Both. The head keyword your competitor ranks for is worth targeting if it fits your site. But the real opportunity is often in the related long-tail terms around that topic — lower competition, easier to rank, and collectively often more traffic than the head term alone.

My competitor ranks for hundreds of keywords I don't. Where do I start?

Filter by three criteria in this order: business relevance first (is this traffic that could actually convert for you?), then difficulty (can your site realistically rank for this?), then volume (is there enough search demand to matter?). The intersection of those three filters gives you your starting list.

What if a competitor ranks for a keyword but their page is thin or low quality?

That's your best opportunity. It signals the keyword has demand but the competition hasn't committed to serving it well. Build a better page — more depth, clearer answers, better structure — and you have a real shot at outranking them.

Can I target competitor branded keywords?

You can target queries like "alternative to [competitor]" or "[competitor] vs [your brand]" — these are fair game and often have strong commercial intent. Targeting their brand name directly is a different matter. It can work in some cases (comparison content, reviews), but the intent is usually navigational, meaning people searching "[competitor]" usually want to go to that site, not discover yours.

How often should I redo competitor keyword research?

Quarterly is a good baseline. If you're in a fast-moving market or actively publishing content, monthly gives you a tighter feedback loop. The main signal that it's time to revisit: you've published a batch of content and want to see what gaps remain, or a new competitor has appeared in your space.
