A keyword gap analysis answers a blunt question: which searches are sending buyers to your competitors that never reach you? It lines up your site's rankings against the rankings of the sites you compete with, isolates the keywords they own and you lack, and turns that list into decisions about which pages to improve and which to build. Done well, it is the fastest way to find proven demand, because every keyword on the list already sends traffic to a business like yours.
We run competitor keyword gap analysis as a fixed-price project inside our keyword research services. The tools can produce a gap report in a few minutes. The value we add is everything after the export: choosing the right competitors, removing the thousands of rows that do not fit your business, checking what Google actually ranks for the important gaps and assigning each one to a page on your site. You get a list your writers and developers can work from on day one.
What Our Keyword Gap Analysis Service Includes
Every project follows the same core method. The plans differ by how many competitors we compare and how far we take the output, from a short list of the top gaps to a full topic and content plan.
| Component | What we do | What it means for you |
|---|---|---|
| Competitor selection | We identify your real search competitors, which are often different from the companies your sales team names, and confirm the list with you. | The comparison reflects who actually takes your clicks, not just who you meet in sales pitches. |
| Missing keywords | Keywords where one or more competitors rank and your site does not rank at all. | Demand you are not competing for, often whole topics or product lines with no page behind them. |
| Weak keywords | Keywords where you rank on page 2 or 3 while competitors sit on page 1 (Gap Analysis plan and above). | The quickest wins, because a page already exists and Google already connects it to the query. |
| Relevance filtering | We remove competitor brand terms, products and services you do not sell, locations you do not serve and keywords with no buying intent. | A list that fits your business, not the competitor's. |
| SERP checks | We read the live results for the highest-value gaps to confirm the intent and the page type that ranks. | You do not build a blog post where Google wants a category page, or the reverse. |
| Page matching | Each gap is matched to an existing URL that should target it or to a proposed new page (Gap Analysis plan and above). | A clear brief for every gap and no new pages competing with the ones you already have. |
| Topic and content gaps | On the Gap and Content Plan, we also look at subjects, formats and supporting content competitors cover that keyword tools miss. | A content plan, not only a keyword list. |
| Priority ranking | Every gap is scored for traffic potential, difficulty relative to your site and business value. | A short, ordered list your team can start on immediately. |
How We Run a Competitor Keyword Gap Analysis
- Brief and competitor shortlist (days 1 to 2). We ask what you sell, which products or services matter most and which markets you serve. Then we pull the domains that overlap most with your rankings in Ahrefs and Semrush, compare them with the competitors you name and agree a final list of three to eight sites, depending on the plan.
- Data pull (days 2 to 4). We run the comparison in Semrush's Keyword Gap tool and Ahrefs' competitive analysis report for your target country, and export your own query data from Google Search Console. Using both tools reduces the blind spots each database has, and Search Console shows keywords you already get impressions for that third-party tools underreport.
- Cleaning and relevance filtering (week 1 to 2). Raw gap exports are mostly noise. We strip out competitor brand names, irrelevant products, wrong locations, misspellings that duplicate other rows and terms with no realistic path to revenue. This step usually removes the majority of rows.
- Grouping and SERP review (week 2). The remaining keywords are grouped by topic, and we check the live search results for the most valuable groups to see what kind of page ranks and how strong those pages are.
- Page matching and priorities (week 2 to 3). Each group is assigned to an existing page or a new page, with a primary keyword, supporting keywords and a short note on what the page needs. Everything is ranked into a priority order.
- Walkthrough call (end of project). We present the findings, explain the top ten actions and answer questions so your team can act on the analysis straight away.
A Gap Snapshot usually takes about one week. A full Gap and Content Plan against eight competitors takes two to three weeks, mostly because of the manual review.
Keyword Gap Analysis Deliverables and How to Read Them
You receive a shared spreadsheet and a short written summary. The spreadsheet has one row per keyword with these columns:
- Keyword, monthly search volume in your target country and keyword difficulty.
- Gap type: missing, weak or shared but trailing.
- Which competitors rank, their positions and the URL that ranks for each.
- Your current position and ranking URL, if you rank at all.
- Topic group and the primary keyword of that group.
- Matched page on your site, or a proposed new URL and working title.
- Search intent, business value rating and priority.
To interpret the results, read the gap types differently. Weak keywords point to pages that need better content, stronger internal links or a clearer focus. Missing keywords where several competitors rank point to topics you should cover. Missing keywords where only one competitor ranks are worth a closer look: sometimes they reveal a smart niche, and sometimes the competitor ranks by accident with an off-topic page.
Success looks like a team that knows exactly which pages to write or improve next, and can track progress by watching the target keywords in Search Console as those pages go live. We do not promise rankings for any gap, because results depend on what you build and how competitors respond.
Keyword Gap Analysis Pricing
Keyword gap analysis is a one-time, fixed-price project. The cost depends mainly on how many competitors we compare, how large those sites are and whether you want only a ranked list of gaps or a full content plan with topic gaps and page matching. Comparing against a handful of focused competitors is a smaller job than comparing against large publishers or marketplaces with hundreds of thousands of ranking keywords.

What Is a Keyword Gap Analysis?
A keyword gap analysis is a side-by-side comparison of the keywords two or more websites rank for, used to find relevant searches where competitors are visible and you are not. The "gap" is the difference between their keyword coverage and yours. It is a form of keyword competition analysis, but instead of judging one keyword at a time, it looks at the whole ranking footprint of each site at once.
Here is a simple example. Imagine an online store that sells espresso machines. A gap analysis against three rival stores shows those stores ranking for "espresso machine descaling", "best grinder for espresso" and "dual boiler vs heat exchanger", while the store ranks for none of them. The first is a support topic that brings existing owners back, the second is a buying guide that sells grinders, and the third is a comparison that shapes which machine people buy. None of these would show up if the store only researched its own product names.
Keyword Gap vs Content Gap Analysis
The two terms are often used interchangeably, but they answer different questions.
| Keyword gap analysis | Content gap analysis | |
|---|---|---|
| Starting point | Ranking data from SEO tools | Topics, questions and buyer journey stages |
| Main output | Keywords competitors rank for that you do not | Subjects, formats and questions your content does not answer |
| Finds | Proven search demand with traffic data | Gaps tools miss, such as low-volume questions, sales objections and missing formats like comparisons or calculators |
| Best for | Prioritizing pages by traffic potential | Planning a complete topic and a stronger content library |
Our Gap and Content Plan combines both. The keyword gap tells you where the measurable demand is, and the content gap review makes sure the pages you build cover the topic as completely as the pages already ranking.
The Four Keyword Gap Types That Matter
Most keyword gap analysis tools sort results into several categories. Semrush, for example, uses filters such as shared, missing, weak, strong, untapped and unique. For decision making, four of them matter most:
- Missing. Every competitor in the comparison ranks and you do not. These are usually core topics for your market and the strongest signal that a page is needed.
- Untapped. At least one competitor ranks and you do not. Wider and noisier than missing, but it is where niche opportunities often sit.
- Weak. You rank, but below every competitor. These keywords usually need page improvements rather than new pages.
- Strong. You rank above every competitor. Not a gap, but worth knowing so you protect these pages during redesigns and migrations.
If someone asks about the four types of gap analysis in a general business sense, they may mean something different, such as gaps in performance, product, market or skills. In SEO, the categories above are the ones that turn into actions.
Keyword Gap Analysis Tools Compared
There is no single best tool for keyword gap analysis. Each database has different coverage, and the right choice depends on your market and budget. These are the tools we use or that clients most often ask about:
| Tool | Strengths | Limits |
|---|---|---|
| Semrush Keyword Gap | Compares up to five domains at once, with clear filters for missing, weak and untapped keywords, plus organic and paid comparisons. | Volumes and positions are estimates, and coverage of small local markets can be thin. |
| Ahrefs competitive analysis | Large keyword index, shows which URL ranks for each gap, and pairs well with Ahrefs backlink data. | Paid plans only for full competitor data, and long exports need careful cleaning. |
| Moz Pro | Keyword gap reports alongside Moz's own difficulty and priority scores. | A smaller database than the two above in many markets. |
| SE Ranking and SpyFu | Lower-cost options for competitor keywords, with SpyFu strong on paid search history. | Smaller databases outside the USA. |
| Google Search Console | Your real queries, positions and impressions, straight from Google. | Shows only your own site, so it cannot reveal competitor keywords on its own. |
A keyword gap analysis free of charge is possible on a small scale. You can search your main topics, note which competitor pages appear, read their headings and compare them with your Search Console queries. It is slow, and it misses most long-tail keywords, but it works for a site with a handful of services. Free trials and limited free tiers of the paid tools can also cover a one-off check.
How to Choose Competitors for a Keyword Gap Analysis
The quality of a gap analysis depends more on competitor selection than on the tool. Pick the wrong sites and you get a long list of irrelevant keywords. These are the rules we follow:
- Use search competitors, not only business competitors. The site that outranks you may be a publisher, a niche blog or a smaller rival you have never heard of. Tools list your organic competitors by keyword overlap, which is a better starting point than a sales list.
- Exclude giants with different intent. Amazon, Wikipedia, Reddit and major news sites rank for everything. Including them buries the useful gaps.
- Compare at the right level. If a competitor sells many product lines and you sell one, compare against the relevant subfolder rather than the whole domain.
- Match the country. A US gap analysis and a UK gap analysis can produce different lists for the same two sites, so we run each target market separately.
- Mix sizes. One larger competitor shows where the market is heading, and two or three similar-sized competitors show what is realistic to win now.
Keyword Gap Analysis Mistakes That Lead to the Wrong Pages
- Treating the export as the answer. Raw gap lists include competitor brand terms, unrelated products and keywords the competitor ranks for by accident. Acting on them unfiltered wastes content budget.
- Building one page per keyword. Many gap keywords are variants of the same search. They belong on one page, not five.
- Ignoring the weak keywords. New pages feel productive, but improving a page that already sits on page 2 is often faster than building something new.
- Skipping the SERP check. A competitor may rank for a keyword with a type of page you cannot or should not build.
- Chasing gaps outside your offer. If a competitor ranks for a service you do not provide, that traffic will not convert for you.
- Running it once and forgetting it. Competitors publish new pages every month. A gap analysis once or twice a year keeps the plan current.
Can ChatGPT Do a Keyword Gap Analysis?
Not on its own. ChatGPT and similar assistants do not have reliable access to ranking positions or search volumes for your site and your competitors, so any keyword gap they produce from a prompt is a guess. They are useful later in the process: grouping an exported keyword list into topics, drafting page outlines for a gap or summarizing what competitor pages cover. We use AI for these supporting tasks and keep the data, filtering and final decisions with a person who reads the actual search results.
Keyword Gap Analysis for PPC and Paid Search
A keyword gap analysis for PPC compares the keywords competitors bid on in Google Ads with the keywords in your own account. Tools such as Semrush's advertising research and SpyFu estimate which terms competitors have bought and which ad copy they ran. The output is useful in two directions: it suggests new keyword groups for your campaigns, and it shows where you are paying for clicks on terms you could earn organically. If both channels are in play, our guide to SEO vs PPC explains how to split keywords between them.
Who Our Keyword Gap Analysis Service Is For
A good fit
- Businesses with an established site that watch competitors win searches they think they should own.
- Content teams that have run out of obvious topics and need a list grounded in real demand.
- Stores and service businesses planning new categories, services or locations.
- Companies preparing a redesign who want to know which topics the new site must cover.
Probably not a fit
- Brand-new sites with almost no rankings. A full keyword research project is the better starting point.
- Markets so small that competitors have very few ranking keywords to compare.
- Teams with no capacity to write or improve pages after the analysis.
Related Keyword Gap and Competitor Services
A keyword gap shows what competitors rank for. Our competitor analysis services explain why they rank, from site structure to content depth. The link gap analysis does the same comparison for backlinks, which often explains why a competitor wins a keyword your page covers just as well. Once the gaps are chosen, keyword mapping assigns them to pages without creating cannibalization. If you want an outside view before buying anything, start with a free marketing audit.
