A content gap analysis finds the searches your competitors rank for and you don't, plus the topics your own pages cover too thinly to rank. You run it by comparing your keyword footprint with two to five real search competitors in a tool like Ahrefs or Semrush, adding your own Search Console data, and turning the gaps worth winning into a prioritized list of pages to create, expand or merge.
This guide is for e-commerce and Shopify teams who want more organic traffic without guessing at topics. You'll get the types of gaps to look for, the tools and what each one actually compares, an eight-step process, how to read keyword gap reports, a prioritization model with real click-through data, and a create, expand or merge decision table you can use on your first list this week.
What is a content gap analysis?
A content gap is any search a potential customer makes that your site doesn't answer well enough to rank. Some gaps are obvious: a competitor has a buying guide for a product you sell and you have nothing. Others are subtle: you have a page, but it skips the subtopics every top result covers, or it's a blog post where Google now shows product listings.
The analysis has two inputs. The first is outside-in: what competitors rank for that you don't, pulled from a third-party keyword database. The second is inside-out: what your own Search Console data says Google already associates with your site, including queries where you appear on page two without a dedicated page. Most teams only do the first. The second is often where the fastest wins are, because Google already sees you as relevant.
Content gap analysis vs. keyword research
Traditional keyword research starts from a seed term and returns volume and difficulty. Gap analysis starts from who already ranks. Every keyword it surfaces is one that a site like yours is earning traffic from today, which tells you the demand is real and the intent fits your type of business. It doesn't replace keyword research; it focuses it.
The types of content gaps to look for
Look for more than missing keywords. These six gap types cover most of the opportunity on a typical store.
| Gap type | What it looks like | Where you find it |
|---|---|---|
| Keyword gap | Competitors rank for a query, you don't rank at all | Ahrefs Content Gap, Semrush Keyword Gap |
| Ranking gap | You rank, but below every competitor | Semrush "Weak" filter, Search Console position |
| Topic gap | A whole cluster of related questions you never cover | Grouping gap keywords by theme |
| Depth gap | Your page exists but skips subtopics the top results cover | Manual review of the top results |
| Format or intent gap | You have a guide where Google shows products, or the reverse | Manual review of the results page |
| Funnel gap | Plenty of top-of-funnel posts, nothing for comparison or buying queries | Mapping your pages by funnel stage |
For e-commerce, funnel gaps are usually the most valuable. Comparison pages ("X vs Y"), "best X for Y" guides, sizing and compatibility pages, and well-written collection pages all sit close to a purchase. If your blog is full of general advice and your competitors own those buying queries, that's where to start.
Tools for a content gap analysis
You don't need every tool. You need one competitor keyword database and your own Search Console data. Here is what each common option actually compares, according to its own documentation.
| Tool | What it compares | Best for |
|---|---|---|
| Ahrefs Content Gap (under Competitive Analysis) | Your domain or URL against up to 10 competitors | Domain gaps and single-page gaps with the Exact URL scope |
| Semrush Keyword Gap | Your domain against up to five competitors, for organic, paid or Shopping (PLA) keywords | Sorting gaps into Missing, Weak, Untapped and other groups |
| Google Search Console | Your own queries, pages, impressions, clicks and positions | Inside-out gaps: queries where you show up but have no strong page |
| Manual results review | The live results page for a query | Depth, format and intent gaps no tool flags |
Third-party tools estimate traffic and rankings from their own crawls, so treat their numbers as directional. Search Console is first-party data from Google, but it only shows queries where you already appear. Used together, they cover both blind spots. Our Google Search Console Analyzer makes the Search Console side faster.
We'll benchmark you against your top three competitors on Google and AI answers, show the pages ready to move, and prioritize the fixes with the revenue math.
How to do a content gap analysis, step by step
- Pick your real search competitors. Choose two to five sites that rank for your most important commercial queries, not just the brands you compete with in stores. A marketplace or a niche blog may be your biggest search competitor. Ahrefs' own guidance suggests starting with one to three.
- Run the competitor comparison. Enter your domain and the competitors in Ahrefs Content Gap or Semrush Keyword Gap, set the country you sell in, and limit results to keywords where competitors rank in the top 10 or 20. Rankings at position 60 rarely mean a competitor has a page worth studying.
- Export and clean the list. Remove competitor brand names, products you don't sell, locations you don't serve and obvious junk. This step often cuts the list by more than half.
- Add your inside-out gaps. In Search Console, export queries from the last three months. Filter for queries with meaningful impressions where your average position is roughly 8 to 30. These are searches Google already connects with your site but no page answers well.
- Group keywords into topics. Cluster terms that one page could answer together. "Best trail running shoes for wide feet" and "wide toe box trail runners" are one page, not two. Each cluster becomes one row in your plan.
- Check each cluster against your existing pages. Search your own site for each topic. If a page already exists, the gap is a depth or ranking gap, and the fix is an update, not a new URL. A keyword map keeps one owner page per topic.
- Review the live results for the top clusters. Look at what format wins (product grid, guide, comparison, video), how deep the top pages go and what questions they answer that you don't.
- Prioritize and assign. Score each cluster with the model in the next sections, then assign each one an action: create, expand, merge or skip, with an owner and a due date.
How to read keyword gap results
Semrush's Keyword Gap groups results by how your rankings compare with your competitors'. Knowing what each group means tells you which action to take.
| Semrush group | Definition (per Semrush) | What to do with it |
|---|---|---|
| Missing | All competitors rank, you don't | Highest-confidence new pages: demand and fit are proven |
| Untapped | At least one competitor ranks, you don't | Wider net; validate each with a results review |
| Weak | You rank, but lower than every competitor | Expand or refresh the page you already have |
| Shared | Every site entered ranks | Benchmark; find where you're close to the top |
| Strong | You rank higher than all competitors | Protect these pages from decay |
| Unique | You rank, no competitor does | Your edge; build related pages around them |
Expect a long tail
Most of what a gap report returns will be low-volume keywords, and that is normal. Ahrefs reports that keywords with fewer than 10 monthly searches make up almost 93% of its US keyword database. Don't dismiss a cluster because each term is small. A single page that answers the topic well can rank for dozens of those terms at once.
Source: Ahrefs, Long-tail Keywords, updated May 2026; Ahrefs, Search Traffic Study, December 2023
The other side of that data is a warning: Ahrefs' 2023 study of about 14 billion pages found that 96.55% get no traffic from Google at all. Publishing a page for every gap keyword is how you add to that number. Group first, then build one strong page per topic.
How to prioritize content gaps
A raw gap list can run to thousands of rows. Score each topic cluster on four factors and work from the top down.
| Factor | Question to ask | Higher priority when |
|---|---|---|
| Business value | Does this topic lead to a product or collection you sell? | The searcher is close to buying |
| Traffic potential | What does the top-ranking page earn across all its keywords? | The whole cluster, not one term, has real demand |
| Ability to rank | Do sites like yours rank in the top 10? | Competitors at your authority level already rank |
| Existing asset | Do you have a page that could be expanded? | Yes, because updating is faster than starting new |
Position decides the payoff
When you estimate traffic potential, remember that clicks are concentrated at the top. First Page Sage's 2026 data from 1,184 domains shows a blended organic click-through rate of 7.1% at position 1, falling to 0.7% by position 5. A gap you can only reach position 8 for is worth far less than its search volume suggests.

| Value | |
|---|---|
| Position 1 | 7.1% |
| Position 2 | 3% |
| Position 3 | 1.7% |
| Position 4 | 1.1% |
| Position 5 | 0.7% |

Two things follow. First, a gap where you can realistically reach the top three beats a bigger gap where you'll stall on the bottom of page one. Second, new pages are slow: in Ahrefs' 2025 study, only 1.74% of newly published pages reached the top 10 within a year. If you have an existing page that's close, expanding it is usually the faster route to position 1 to 3. The CTR calculator helps you run this math for your own clusters.

Create, expand or merge: what to do with each gap
Once a cluster makes the cut, decide whether it needs a new page or a better existing one. Creating a new URL when you already have a relevant page is the most common way gap analysis backfires, because the two pages end up competing.
| Situation | Action | Next step |
|---|---|---|
| No page covers the topic and the intent is distinct | Create | Brief a new page matched to the winning format |
| A page exists but misses subtopics or ranks on page two | Expand | Add the missing sections and refresh the facts |
| Two or more of your pages split the topic | Merge | Combine into the strongest URL and 301 the rest |
| Results favor products and you have a collection page | Optimize the collection | Add intro copy, FAQs and internal links to it |
| Low value, wrong intent or out of reach | Skip | Log it and revisit next quarter |
Before you create anything, check that the new page won't overlap an existing one. The Keyword Cannibalization Checker shows queries where two of your URLs already compete. For expansions, our guide to content refreshing covers how to update a page without losing what it ranks for, and if the gap list exposes thin pages you'd rather remove, see content pruning.
Build topic clusters, not one-off posts
When several gap clusters sit under one theme, plan them together: a main guide or collection page plus supporting pages that link to it and to each other. That structure helps search engines and readers see the depth of your coverage, and it makes future gaps easier to spot. Our guide to topical authority covers how to plan the cluster.
Common content gap analysis mistakes
- Comparing against the wrong competitors. Your biggest retail rival may not be your biggest search competitor. Use the sites that actually rank.
- Chasing volume over intent. A high-volume informational keyword with an AI answer may send fewer buyers than a small comparison query.
- One page per keyword. Splitting a topic across several thin pages creates cannibalization and adds to the pages that get no traffic.
- Ignoring your own data. Search Console queries on page two are gaps Google has already half-closed for you.
- Treating tool estimates as facts. Third-party traffic numbers are modeled. Use them to rank opportunities against each other, not to forecast revenue precisely.
- Running it once. Competitors publish every month. Repeat the comparison quarterly and after any big competitor launch.
Your first content gap analysis
Keep the first pass small enough to finish. Pick three real search competitors, run one comparison, clean the list, add your Search Console page-two queries, and group everything into topics. Score the top 20 clusters, decide create, expand or merge for each, and put the top five on this month's content plan. Then track rankings and clicks for those pages so the next round is based on what worked.
