What is a content gap analysis?

A content gap analysis identifies relevant subjects your website has missed or could explain better. A gap can also be an unclear answer or content that fails to meet the reader's needs. Semrush's guide describes these different forms.

Separate a missing topic from a missing explanation

A domain-level gap concerns a topic absent from your site. A page-level gap concerns an existing topic where a competing page ranks for additional keywords. These are the two levels described in Ahrefs' workflow.

Hypothetical example: a cleaning company has an office cleaning page but no information about preparing an office before the cleaners arrive. Check whether a short preparation section would answer the question. Do not automatically commission another article.

For this exercise, use a content audit to review what you already publish. Use the gap analysis to decide which unanswered questions deserve work. Keep both decisions in one spreadsheet so the review ends with something a writer can act on.

Where should a small business start?

Choose one offer and one audience. For a freelance designer, that could be logo projects for independent shops. Leave website projects and large corporate clients outside this first review.

Write the customer's questions first

Collect questions from enquiries, sales conversations and support requests. Customer conversations and reviews can expose needs beyond keyword lists, as Semrush explains. Record the question without copying personal customer details.

• What does the customer need to understand before choosing?
• What must they provide before work starts?
• Which alternatives are they comparing?
• What happens after they order?

Then list the existing pages that should answer those questions. Beside each page, write the answer you found or mark it as missing. Read the page itself before making that call.

A keyword is a phrase someone searches for. Turn your customer questions into a small set of candidate phrases, using the guide to finding specific search phrases if you need help. Keep different wordings of the same question together for now.

How do you compare competitor content without copying it?

Search your candidate questions and open relevant pages. Choose competitors serving a similar customer, then compare the answers they provide. Write down useful missing information rather than collecting headings to imitate.

Run a manual comparison first

For each competitor page, record its main question, practical advice and supporting examples. Next, inspect your closest equivalent. Describe the difference in plain language, such as “our page does not explain what the customer must send us.”

Search intent means what the person wants to accomplish with the search. An intent gap exists when content does not meet that need, according to Semrush's classification. Use the search intent guide before deciding that every question needs a blog post.

Use tools to expand the candidate list

Ahrefs Competitive Analysis compares your domain with competitors to find keywords they rank for and you do not. Its guide also recommends removing irrelevant topics and competitor brand terms. See the Ahrefs process.

Semrush Keyword Gap offers “Missing” for terms all entered competitors rank for but you do not. “Untapped” includes terms where at least one competitor ranks and you do not. These filters are explained in the Semrush walkthrough.

Treat either export as a research list. Before approving a topic, write down why your customer needs the answer and what your business can contribute. If you cannot complete those two sentences, set it aside.

How can you find content gaps with Google Search Console?

Look for relevant queries associated with your website, then inspect whether your pages answer them. Search Console's Performance report shows your site's Google Search performance and lets you group data by queries or pages. Google documents these views.

Read the numbers before interpreting them

Impressions count appearances in search results. Clicks count visits through those results, while CTR is clicks divided by impressions. These definitions come from Google's report documentation.

1. Choose a date range and keep it consistent during the review.
2. Read the Queries table and note relevant customer questions.
3. Use the Pages view to examine the appropriate pages.
4. Open each page and look for a clear answer.
5. Record an edit only when you can identify what is missing.

Hypothetical example: a bicycle shop appears for a question about choosing a commuter bike size. Its buying guide explains frame materials but says little about sizing. Ask the writer to add a practical sizing explanation using information the shop can verify.

Keep observation and recommendation separate. “This query appears in our report” is an observation. “Add a sizing section” is your proposed response, which still needs editorial judgment.

The report concerns your own site's search performance, so do not use it as a complete competitor keyword database. That scope is clear in Google's overview. Combine these observations with the manual comparison instead.

Which gaps should become new pages?

Choose the action that answers the question with the least unnecessary duplication. First check whether a suitable page exists. Ahrefs recommends considering new sections for existing pages and creating pages where the topic is absent. Its decision process provides the basis for this check.

Copy this content gap analysis template

Use one row per customer question. Add the evidence, current page, missing answer, proposed action and owner. The following entries are hypothetical planning examples, not measured business results.

Prioritize with three practical questions

• Does this help someone who could realistically buy from us?
• Do we have evidence that the answer is needed?
• Can we provide a useful, accurate answer now?

Start with a gap that has clear answers to all three. For related questions, plan a main guide and supporting pages using the topic cluster guide. A topic cluster is simply a connected group of pages about one broader subject.

Before commissioning separate pages for similar phrases, compare the answers they would contain. If the plans substantially overlap, review the guide to overlapping keyword targets. Decide which existing page should handle the question before assigning more writing.

How do you turn the findings into work this week?

Finish the review with one clearly assigned update and one new-page outline at most. This is a suggested starting workload, not a required publishing schedule. Adjust it to the time your team actually has.

Give the writer a concrete assignment

Include the reader, question, existing page, missing answer and evidence to use. Specify the next step the reader should be able to take. The content brief template can help organize that assignment.

Hypothetical brief: “Update the cleaning service page for office managers preparing for their first visit. Explain access arrangements, desk preparation and where to raise special requests. Have the operations manager verify every instruction before publication.”

Ask someone unfamiliar with the draft to follow its instructions. Mark any point where they have to guess. Give those notes back to the writer before calling the gap closed.

Record the change and review it

Save the previous search figures, the edited page and a short change note. Choose a review date and compare equivalent periods. Search Console supports different date ranges and performance measures, as described in Google's documentation.

Also review whether the same unanswered question still appears in enquiries. Use that observation to decide whether the explanation needs another edit. When the new answer is ready, apply the internal linking guide to connect relevant existing pages to it.
