4 Steps To a Content Gap Analysis for SEO in 2026

In SEO, content gap analysis is identifying the topics, keywords, and formats your competition writes about but that your website is missing. Comparing the two and ranking those gaps on demand and difficulty before filling the highest ones is key. There are four steps to making it consistent.

As defined by Ahrefs, “content gap analysis is the identification of topics that your competitors write about but that you do not,” and Ahrefs lists three benefits as well: traffic to existing content, topics to write about, and traffic from your competitors (Source).

Depth matters too. “The quality of the content includes whether it provides a substantial, complete, or comprehensive description of the topic” (Source), which is precisely what the gap analysis answers per page.

In the case of Jidoka Technologies, we analyzed more than 6,600 keywords and identified gaps for four competing sites, and the website currently ranks for 677 keywords, 33 of them in the top three.

This guide will explain each of the four steps, the tools that speed them up, and how to measure the result.

Understanding Content Gap Analysis

What is content gap analysis? It is an assessment of your pages compared to competing pages in order to determine the things that your website is lacking. What is content gap analysis in SEO, specifically? It is the same process of comparison based on search parameters: keyword, topic, format, and search intent.

Ahrefs distinguishes between two gap categories. A domain-level gap is one where the competitor addresses the topic that your site is lacking in, whereas a page-level gap is where you both have pages on the topic but yours ranks for fewer keywords since their page provides more depth.

A third perspective comes from a web traffic gap analysis. This kind of comparison involves the comparison of estimated organic traffic by pages and topics on your domain and the domains of your competitors, thereby showing you areas where your competitors are getting visitors you are not getting.

An SEO content gap analysis also helps you save money. Without it, your team writes content on the topics that they are interested in while the topics that searchers are using remain unused on your site.

Content gap analysis SEO managers can repeat needs three inputs: your pages, competitor pages, and search data.

A strong SEO content gap analysis delivers four things:

• Better visibility in search results
• A clear view of content weaknesses and competitor wins
• A ranked content plan
• Pages that answer more of what your audience asks

The table below lists the five gap types we check on every site.

Step-by-Step Guide to Performing Content Gap Analysis

1. Audit Your Existing Content

We begin our analysis in the Google Search Console. The Performance report features clicks, impressions, CTR, and average position by query and page. This report is updated with the information for the previous three months by default.

We should export the Pages and Queries reports to Google Sheets. Next, we add the columns for topic, search intent, and the latest update. After that, we find pages that are outdated, duplicate, and competing for the same query. These pages require improvement before the team creates new pages. New pages will not fix such issues.

Then we sort the Queries report by impressions. A query with a lot of impressions and low average position becomes our closest target. Since Google shows this page on SERP, it only needs a reason to rank it higher.

DianaHR shows the importance of conducting an audit first. We devoted one month to deleting the content causing keyword cannibalization, fixed all technical issues, the traffic decreased but after that it increased by 121% per month, from 635 to 1,401 visits, and the number of ranked keywords increased from about 200 to more than 1,500.

2. Analyze Competitors’ Content

Pick competitors from the live search results, not from your business plan. The sites that rank for your target queries are your real competitors. Three to five is enough. Run the SEO gap analysis against the same set each quarter so results stay comparable.

A publisher or a software vendor can outrank you on informational queries while selling something entirely different, so include them. They compete for the same reader, which is what a gap analysis measures.

In Ahrefs, enter your domain and one to three competitors in the Competitive Analysis tool, set it to keywords, and click “Show keyword opportunities.” Semrush’s Keyword Gap tool compares up to five domains and sorts results into categories such as Missing, Untapped, and Weak.

• Missing: every competitor ranks, and you do not.
• Untapped: you do not rank for the term, but at least one competitor in the report does.
• Weak: you rank, but lower than every competitor.

For traffic gaps, compare estimated organic traffic by page in the same tools. A page that drives heavy traffic to a rival and none to you marks a high-value gap.

3. Identify Content Gaps

An SEO gap analysis is going to yield large lists, so you should filter them out. As per Ahrefs, you should eliminate competitor brand names and irrelevant phrases, focus on keywords that at least two competitors appear on within the first ten search results, and set a monthly minimum of 20 and a maximum Keyword Difficulty of 30.

Moreover, as Ahrefs notes, if the list is above 100,000 keywords, it is likely to crash its Google Sheets template. In Ahrefs’ own example, their competitor had 120 keywords for which their page was being searched, while the author’s page had none; those keywords were worth 2,187 estimated monthly visits, but they were irrelevant to the author, who, therefore, chose to disregard them.

However, check the intent behind those keywords before doing anything. Check if the top results for your chosen keyword include guides, lists, tools, or product pages. The blog post will not be able to compete with a product page.

After the intent check, ask these four questions of every gap you plan to fill:

• Which competitor keywords do we lack?
• Which content formats do competitors use that we do not, and which of those formats rank best for the target query?
• Which audience questions do we leave unanswered?
• Which buying stage has no page?

4. Develop a Plan to Fill the Gaps

Each gap will be turned into a task. Domain-level gaps are translated into new pages, while page-level gaps translate to new sections on existing pages. Before producing any content, check your domain with a site: command to see whether the page already exists in your domain.

Prioritize the list based on search demand, keyword difficulty, fit for the business and efforts required. In each short description, mention the query, the recommended sections, the supporting keywords, the search intent and one competitor page that you have to beat.

Depth works wonders. Backlinko examined 11.8 million Google search results and concluded that there was a correlation between Content Grade and rankings; for the top 30 results, one grade point corresponded to one ranking position. It is a correlation study, so it cannot establish cause (Source).

Implementing Your Findings

Write each page to the brief, then check it against this list before you publish.

• Put the target query in the headline and the first sentence.
• Cover every missing subtopic from the gap report, and answer the questions your audience asks in sections with clear headings, so a reader who skims the headings still finds each answer.
• Add a conclusion that points the reader to one clear next step, such as a contact page, a download, or a related guide.
• Link to related pages on your site and to credible sources, and check that every link opens the right page.
• Keep one consistent voice across the page.

Page-level gaps need a different workflow. Open the existing page, list the subtopics the competing page covers that yours skips, and add them as sections, keeping the URL unchanged so the page keeps its history. Update the date only when the content changes in a way a reader would notice.

Google adds a transparency test: make clear who wrote the content, how it was made, and why it exists. Its stated goal is content created primarily to help people. Show the author on the page.

Measuring Success and Iterating

Monitor each newly created page on Search Console for impressions, clicks, and average position and on Google Analytics for engagement and conversions. Allow time for the results to come through.

With Jidoka Technologies, the clicks spiked drastically in December 2025 when the keywords were in better positions, having recorded over 6,550 clicks and 843,000 impressions within six months. You should use a trend over a quarter to make judgments on a gap.

The impressions usually come first, followed by the average position, and then the clicks. When there is an increase in impressions and clicks have remained unchanged for two or three months, then change the title and meta description and not the body as the page is being seen and not clicked.

Repeat the analysis quarterly. The competitors will be publishing and the pages getting older; thus, a scheduled content gap analysis SEO can help keep the plan up to date. Quarterly content gap SEO report will also give the gaps that have been fixed.

Conclusion

A gap analysis turns guesswork into a ranked list. Audit what you have, compare it with the pages that outrank you, filter the gaps by demand and difficulty, and fill the best ones with pages that go deeper than the competition, because depth is the difference between a gap you close and one you merely cover.

• Audit your pages in Search Console first.
• Compare three to five real competitors.
• Filter gaps by volume, difficulty, and relevance, and keep the list short enough to finish.
• Repeat every quarter.
