How to Do a Content Gap Analysis

Most websites do not have a traffic problem. They have a content coverage problem. Your competitors are ranking for keywords you have never targeted, answering questions your audience is asking, and showing up in AI-generated answers your brand is completely absent from. A content gap analysis finds exactly where those gaps are and tells you what to build next.

This guide walks you through the full process, from identifying missing keywords to mapping content to your customer journey and checking your AI search visibility.

Step 1: Understand What a Content Gap Analysis Is

A content gap analysis is the process of comparing what content your site currently has against what your audience is searching for and what your competitors rank for. The goal is to find the topics, keywords, and questions your site does not cover yet but should.

A thorough content gap analysis covers three layers:

Most businesses only ever look at the first layer. The sites that dominate search cover all three, and increasingly a fourth: AI visibility gaps, which we cover in Step 7.

Step 2: Audit Your Existing Content

Before you can find what is missing, you need a clear picture of what you already have. A content audit tells you what pages exist, what they rank for, and which ones are actually performing.

Here is how to do it:

1. Export all your URLs from Google Search Console or your sitemap.
2. Check each page's performance in Google Search Console. Look at impressions, clicks, average position, and top queries for each URL.
3. Group pages by topic. Which topics do you already cover well? Which has only one weak page?
4. Flag thin or underperforming content. Pages with high impressions but low clicks, or pages sitting below position 20 for their target keyword, are candidates for a refresh rather than a new page.

This audit gives you two things: a map of your existing content and a list of pages that need improvement before you add anything new. Fixing weak existing pages almost always produces faster results than publishing new content from scratch. This is true whether you run an e-commerce business, a law firm, a dental office, or a SaaS company.

Step 3: Identify Your SEO Competitors for Content Research

Your content gap analysis is only as good as the competitors you measure against. Your SEO competitors for content purposes are the sites that rank on page one for the keywords your audience searches for. These are not always your direct business competitors.

How to Find Them

1. Search your five most important keywords in Google.
2. Note which sites appear most consistently across all five searches.
3. Add any sites that appear in the People Also Ask box or featured snippets for those queries.
4. Build a list of four to six content competitors to analyze.

The process is the same whether you are a small business, a real estate agency, or a tech startup.

Look for sites that regularly publish content in your space, even if they do not sell the same product or service. Industry blogs, comparison sites, and educational platforms often outrank direct competitors on informational keywords and represent your biggest content gap opportunities.

Step 4: Run a Keyword Gap Analysis

A keyword gap analysis is the core of any content gap process. It identifies every keyword your competitors rank for that your site does not. These missing keywords represent content your audience is searching for right now, with no page on your site to capture it.

How to Do It with a Tool

Tools like Ahrefs Content Gap, Semrush Keyword Gap, and Moz's True Competitor show you this data automatically. Enter your domain alongside two or three competitors and the tool produces a list of all keywords they rank for that you do not.

How to Categorize What You Find

Not every gap is equal. Sort your findings into four categories to prioritize effectively:

‍

Start with missing keywords that have clear search intent, manageable difficulty, and direct relevance to what you sell. These are your fastest ranking wins.

Understanding keyword research fundamentals helps you interpret gap analysis data more accurately and prioritize opportunities with confidence rather than guesswork.

Step 5: Analyze Competitor Content to Find Topic Gaps

Beyond keywords, look at what topics your competitors cover that you have no content about at all. This goes deeper than keyword data. It is about understanding which subjects your audience cares about and which ones your site completely ignores.

What to Look For on Competitor Sites

1. Blog categories they publish in regularly — If a competitor has 20 posts on a topic you have never covered, that is a strong signal of audience interest.
2. Their top pages by estimated traffic — Use Ahrefs or Semrush to find which pages send them the most organic visitors. Those topics have proven demand.
3. Questions they answer in their content — Read the headings and subheadings of their top posts. Every H2 that covers a topic you have not written about is a content gap.
4. Their People Also Ask coverage — Search a competitor's main topics and look at the PAA boxes. If they have content targeting those questions and you do not, add them to your gap list.

You can speed up this research by using ChatGPT for keyword research to summarize a competitor's content and identify which subtopics they cover most thoroughly before you build your own pages. The ChatGPT cheat sheet has ready-to-use prompts for exactly this kind of analysis.

Step 6: Map Content Gaps to the Customer Journey

Not all content gaps are created equal. A keyword with high search volume is worthless if it attracts people who will never buy from you. Mapping your content gaps to the customer journey tells you which gaps drive real business outcomes and which ones just drive traffic.

The customer journey has three stages, and you need content at each one:

Most content gap analyses find that websites are heavy on awareness content and almost completely missing consideration and decision-stage content. That is where conversions happen. A visitor who reads your blog post but finds no comparison page, no case study, and no clear path to your service will leave and convert on a competitor's site instead.

For each gap you identify, ask: which stage of the journey does this keyword belong to? Then check whether you have content at that stage. If you do not, those are your highest priority gaps to fill.

We do this for clients across industries, from accounting firms and financial advisors to restaurants, gyms, and moving companies.

At ReachGiant, we map every content gap to a specific stage of the customer journey before recommending what to build. It is the difference between content that drives traffic and content that drives revenue. If you want us to run this analysis for your site, book a free call.

Step 7: Evaluate Your AI Search Visibility Gaps

This is the step most content gap analyses skip entirely. It is also the one that will matter most in the next two years.

AI-powered search tools including ChatGPT, Google AI Overviews, Perplexity, and Gemini now generate answers to user queries by pulling from content across the web. Your website might rank on page one for competitive keywords yet remain invisible when millions of users ask AI platforms the same questions. This is a growing problem for enterprises, hospitals, and software development firms in particular, where branded queries are common in AI search.

That is an AI visibility gap, and it is a new category of content gap that traditional keyword tools cannot detect.

Research suggests that the overlap between top Google links and AI-cited sources has dropped from 70% to below 20%. Ranking well in Google no longer guarantees you will appear in AI-generated answers. The two systems are increasingly separate, and your content strategy needs to account for both.

How to Check Your AI Visibility

1. Search your main topics in ChatGPT, Perplexity, and Google AI Overviews. Ask the same questions your customers would ask. Note which brands and pages are cited in the answers.
2. Check whether your site is cited. If competitors appear and you do not, that is an AI visibility gap.
3. Look at what content the AI cites. AI systems favor content that answers questions directly, uses clear structure, includes data and expert sources, and demonstrates authority on the topic.

How to Close AI Visibility Gaps

• Add direct question-and-answer sections to your most important pages. AI systems pull answers from content that addresses questions explicitly.
• Include data, statistics, and original research in your content. AI systems cite sources that provide factual, verifiable information.
• Use clear heading structures with H2s and H3s that match the questions your audience asks. AI crawlers parse headings to understand what a page covers.
• Build topic authority by covering a subject across multiple pages that link to each other. AI systems favor brands with broad, consistent expertise on a topic.

Content with proper schema markup shows 30 to 40% higher AI visibility. Adding FAQ schema, HowTo schema, and Article schema to your key pages is one of the fastest technical stepsb you can take to improve AI search coverage.

Step 8: Build Your Content Gap Action Plan

All of the research above only creates value when it leads to a prioritized plan. Here is how to turn your findings into a content calendar you can actually execute:

1. Start with quick wins. Pages ranking positions 11 to 20 need a title tag update, a few internal links, and possibly a content refresh. These move the fastest.
2. Fill high-intent missing gaps next. Keywords with clear consideration or decision-stage intent that have no page on your site yet. These drive leads directly.
3. Build awareness content for AI visibility. Informational content that answers specific questions in a clear, structured format. This is what AI systems cite most often.
4. Refresh thin competitor-beating content. Where competitors have weak, outdated pages on topics with strong demand, build a better version and promote it.
5. Plan long-term topic clusters. Group related keywords into clusters and build a pillar page with supporting posts. This builds topical authority over time.

Assign each gap a content type, a target keyword, a journey stage, and a publish date. A gap analysis without a calendar is just a list of good intentions. Whether you are an IT service provider, a logistics company, or a fashion and apparel brand, the calendar structure is the same, only the keywords change.
