How to Check a Keyword Gap (Step by Step)

To check a keyword gap, you pull the search terms your competitors rank for, remove the ones you already cover or cannot realistically win, and keep the terms where they show up and you do not. That remaining list is your gap, and it tells you exactly where to point your next few months of writing. This guide walks through the whole process, from picking competitors to building a calendar, so you can check a keyword gap without guessing.

The idea is simple. Two sites in the same space will never rank for an identical set of keywords. Wherever a rival earns traffic that you miss, there is a page you could probably build to compete. Finding those spots is less about clever tools and more about a repeatable routine you run every quarter.

What Is a Keyword Gap in Plain Language?

A keyword gap is any keyword your competitors rank for on Google that your site does not. Picture two overlapping circles. One holds the terms you rank for, the other holds your competitor's terms, and the slice that belongs only to them is the gap. Those are proven demand, because someone already ranks and earns clicks for them.

This matters more every year as the open web gets quieter. In the first four months of 2026, 68% of U.S. Google searches ended without a click, according to SparkToro's clickstream analysis. When fewer searches send traffic anywhere, the ones that still do become more valuable, so you want to compete for the exact terms that already feed your rivals.

Gaps come in a few flavors. Sometimes a competitor ranks on page one and you are nowhere. Sometimes you both rank, but they sit at position three and you languish at position fifteen. Both count, and both are fixable.

Step 1: Pick the Right Competitors to Compare

Your first job is choosing whose rankings to study, and the obvious choice is often wrong. Your business rivals and your search rivals are not always the same sites. A local law firm might compete with national legal directories for clicks, not the firm down the street.

Follow these rules when you build your list:

1. Search a few of your own target terms and note which sites keep appearing in the top ten. Those are your real search competitors.
2. Include a mix of sizes. Pick one or two sites roughly your size and one larger authority to see both reachable and aspirational gaps.
3. Favor content-driven sites over pure product or directory pages, since they share more realistic keyword targets with a blog.
4. Cap the list at three to five. This keeps the next steps manageable and the patterns readable.

A quick way to sanity-check your picks is to ask whether you would be happy taking their blog traffic. If yes, they belong on the list. If their audience is a different world from yours, drop them.

Step 2: Pull Their Rankings With a Keyword Gap Tool

Once you have your competitors, pull the keywords they rank for. Almost every SEO platform ships a dedicated keyword gap or content gap feature where you enter your domain alongside two or three competitor domains, and it returns a table of terms they rank for and you do not.

If budget is tight, you can approximate the same output in stages: many platforms offer a limited free trial, and you can compare two competitor domains at a time to stay under usage caps.

Here is what to export from the tool:

• The keyword itself
• Its monthly search volume
• A difficulty or competition score
• The competitor's ranking position for that term
• Your position, if you rank at all

Dump all of it into a spreadsheet. Raw gap exports are noisy, often thousands of rows deep, so resist the urge to act on the first screen. The real work is the filtering that comes next.

Pair this export with your own Google Search Console data. Search Console shows terms you already earn impressions for, which helps you spot near-misses where a small push could move you up rather than starting from zero.

Step 3: Filter for Winnable Terms

A raw gap list is mostly junk, and this step separates signal from noise. Winnable means a term you could realistically rank for in the next few months with one good page, not a keyword that demands a hundred backlinks you will never get.

Cut these categories first:

• Competitor brand searches. You will never rank for "Acme Corp login," so delete every branded term.
• Irrelevant queries. Big sites rank for stray topics far outside your niche. If a term does not fit your business, it goes.
• Terms miles above your authority. A brand-new blog chasing "best crm software" is wasting effort. Park the giants for later.
• Near-duplicate variations. Collapse "how to check keyword gap" and "checking keyword gaps" into one target so you do not plan three pages for one intent.

What remains should be terms where a competitor near your size ranks, the topic suits your audience, and the difficulty sits within reach. That is your shortlist. A gap you cannot act on only distracts you, so be ruthless here.

Step 4: Prioritize Gaps by Volume, Intent, and Difficulty

Your shortlist still needs ordering, because you cannot write everything at once. Judge each term on three signals together, never one in isolation. A high-volume keyword you cannot rank for beats nothing, and an easy keyword nobody searches earns nothing.

Weigh these three factors:

• Search volume. Higher is generally better, but do not chase vanity numbers. Modest, specific terms often convert far better than broad ones.
• Intent. Match the term to where the searcher sits. Informational queries like "check keyword gap" build trust and future demand, while commercial queries signal readiness to buy. A healthy plan mixes both.
• Difficulty. Be honest about your site's current authority. Terms where a same-size competitor already ranks are your green-light zone.

Why does position matter so much? Because the clicks collapse fast as you slide down the page. Position one earns a 20.02% organic click-through rate while position three draws just 3.89%, per Advanced Web Ranking's 2026 study. Targeting a winnable gap where you can actually reach the top three is worth far more than ranking tenth for something huge.

A simple scoring approach works well. Rate each term one to five on volume, intent fit, and ease of ranking, then sort by the total. The terms that score high on all three rise to the top, and those are your first assignments.

Step 5: Turn the Shortlist Into a Dated Content Calendar

A prioritized list sitting in a spreadsheet changes nothing. The final step converts it into a dated calendar with one keyword assigned to one piece of content on one publish date. This is where analysis becomes habit, and habit is where the compounding happens.

Build the calendar like this:

1. Assign one primary keyword per article. Group the near-duplicates you kept as supporting terms under that single target.
2. Set a realistic cadence. Weekly beats a burst of ten posts followed by three silent months. Pick a pace you can sustain.
3. Date every entry. A keyword with a publish date is a commitment; a keyword without one is a wish.
4. Front-load your highest-scoring gaps so your best opportunities ship first while interest and momentum are high.

The honest truth most SEO advice skips is this: the keyword gap was rarely the hard part. The hard part is still being there in month six, publishing the twelfth article after the novelty wore off. A calendar you actually follow is the whole game, which is why our guide to building a daily SEO content calendar that sticks spends more time on cadence than on topics.

This is also the step where a tool like Bunzy earns its keep. It analyzes your site, surfaces winnable keywords, and publishes to your domain on a set schedule, so the gap analysis you ran once keeps producing pages long after the spreadsheet would have gone stale. Your judgment still sets the direction. The automation just makes sure the showing-up part no longer depends on a free afternoon that never comes.

Your Next Move

Open a blank spreadsheet and list three competitors who keep beating you in search. That single action, done this week, puts you ahead of every rival still meaning to get around to it. Run the five steps on those three names, pull out your top five winnable gaps, and give each one a date on the calendar. The rankings follow the sites that keep showing up, and now you know exactly what to show up and write.
