Content Gap Analysis: Find What Your Competitors Rank For and You Don’t

A manual content gap analysis is the process of identifying topics, questions, and keywords your competitors rank for that your site does not. Done properly, it tells you exactly where your content strategy has holes and gives you a prioritised list of what to create next.

You do not need a paid tool to do this well. A spreadsheet, a few free resources, and a few hours of focused thinking will get you further than most automated gap reports, because the thinking behind the process is what creates the value, not the software.

I have run this process dozens of times across different industries, from SaaS businesses trying to grow organic pipelines to professional services firms with almost no content presence at all. The mechanics are broadly the same. What changes is how you interpret what you find. That is the part that requires judgment, not just process.

Why Manual Still Beats Automated for Gap Analysis

Automated content gap tools are useful for generating lists. Ahrefs, Semrush, and Moz will all show you keywords your competitors rank for that you do not. That is a reasonable starting point. But the output is always a raw list, and raw lists require human judgment to become strategy.

When I was growing an agency from around 20 people to over 100, we were pitching clients across multiple verticals simultaneously. The content decisions we made for our own site had to be deliberate, because we did not have the bandwidth to publish at volume. Every piece had to earn its place. That discipline, deciding what not to create as much as what to create, is something automated tools cannot give you. They will happily surface 400 gap keywords. They will not tell you which 12 actually matter for your commercial goals.

Manual analysis also forces you to read the competing content. That is not a small thing. When you read what ranks, you understand why it ranks. You see the depth, the structure, the angle, the credibility signals. You also see the weaknesses. Those weaknesses are your opportunities, and they are invisible in a keyword export.

If you want a broader framework for how content gap analysis sits within a content programme, the Content Strategy & Editorial hub covers the full planning and execution cycle in detail.

Step 1: Define Your Competitor Set Properly

Most people start a content gap analysis by listing their commercial competitors. That is the wrong place to start, or at least an incomplete one. Your content competitors are the sites that rank for the topics you want to rank for. They are not always your business competitors.

A SaaS company selling project management software might find that its commercial competitors are Asana, Monday, and Notion. But its content competitors for mid-funnel informational queries might be productivity blogs, HR publications, and management consultancies. Those are the sites worth analysing for content gaps, not just the direct product competitors.

Start by searching for 10 to 15 of your most important target keywords in Google. Note which domains consistently appear in the top five results. Build a shortlist of four to six content competitors based on that exercise. Include at least two that are not your direct commercial rivals.

Then do the same exercise for your secondary topic clusters. You may find different sites dominating different areas. That is useful information. It tells you there is no single dominant authority in your space, which usually means the gap is closable with focused effort.

Step 2: Crawl and Catalogue Competitor Content

You do not need a paid crawler for this. Screaming Frog’s free tier handles up to 500 URLs, which is enough for most competitor sites in a focused niche. Use it to pull a list of all indexed pages from each competitor domain. Export to a spreadsheet.

For each competitor, you are looking at:

• The URL structure (how they organise content by topic)
• Page titles (what topics and angles they are targeting)
• Approximate content depth (thin pages versus substantive guides)
• Content types (blog posts, landing pages, resource hubs, tools)

You are not reading every page at this stage. You are building a map of their content territory. Once you have that map, you can compare it against your own content inventory and start identifying where the gaps are.

If you have not already done a full audit of your own content, that needs to happen first. You cannot identify gaps without knowing what you already have. For SaaS businesses specifically, a content audit for SaaS typically surfaces a significant amount of thin or duplicate content that should be consolidated before any gap-filling begins.

Step 3: Map Topics Against Search Intent

This is where most content gap analyses go wrong. People identify a topic their competitor covers and they do not have, and they immediately brief a piece of content to fill it. But covering a topic is not the same as covering it for the right intent.

Search intent has four broad categories: informational, navigational, commercial investigation, and transactional. A single topic can have content needs across all four. If a competitor has a strong informational piece on a topic and you only have a product page, the gap is not just about the topic. It is about the intent layer you are missing.

When I was judging Effie entries, one of the consistent patterns in underperforming campaigns was content that addressed the right topic but the wrong moment. A brand would create brilliant awareness content for an audience already in purchase consideration, or detailed comparison content for people who had just discovered the category. Intent alignment is not a nice-to-have in content strategy. It is the difference between content that builds pipeline and content that generates page views with no commercial consequence.

For each gap topic you identify, note the dominant intent behind the searches. Use Google’s autocomplete, People Also Ask results, and the actual SERP layout (are there product listings? Are there long-form guides? Are there video results?) to understand what Google believes the searcher wants. Then assess whether your gap-filling content plan matches that intent.

The Content Marketing Institute’s planning framework is worth reading alongside this step. It puts intent mapping within a broader strategic context that helps you see how individual pieces connect to audience experience stages.

Step 4: Score and Prioritise Your Gap List

By this point you will have a list of topics your competitors cover that you do not, organised by intent. The next step is prioritisation, and this is where commercial judgment matters more than any scoring formula.

A simple scoring matrix works well here. Score each gap topic across three dimensions:

• Commercial relevance: How closely does this topic connect to your product, service, or conversion goals? Score 1 to 3.
• Search volume and difficulty: Is there meaningful demand, and can you realistically compete? Score 1 to 3.
• Content production feasibility: Do you have the expertise and resource to create something genuinely useful on this topic? Score 1 to 3.

Topics scoring 7 or above are your priority tier. Topics scoring 4 to 6 are your secondary tier. Topics scoring below 4 should be deprioritised or dropped entirely, regardless of how much traffic your competitor gets from them.

This matters especially in specialist verticals. I have worked across highly regulated and technically complex sectors, and the temptation is always to chase volume. But a piece of genuinely authoritative content on a low-volume, high-intent topic in something like life science content marketing will outperform a generic high-volume piece every time, because the audience is smaller but the commercial stakes are higher and the bar for credibility is much steeper.

The same principle applies in government contracting contexts. B2G content marketing operates on long procurement cycles where trust and demonstrated expertise matter far more than reach. Filling gaps with thin, traffic-chasing content in that environment actively damages your credibility with the audience that matters.

Step 5: Audit Depth, Not Just Coverage

Once you have your priority gap list, go back and read the competitor content that ranks for those topics. Not skim it. Read it properly. You are looking for three things:

• What they cover well: You need to match this as a baseline. If you cannot match the depth on the core topic, do not publish yet.
• What they miss or underserve: This is your differentiation opportunity. Most content that ranks is not excellent. It is adequate. Finding where it is thin or where it avoids complexity is where you create genuine value.
• What has changed since they published: A lot of ranking content is old. If the topic has evolved, the gap is not just coverage, it is currency. Fresh, accurate content on a topic where the ranking piece is outdated is one of the most reliable ways to displace an established competitor.

This depth audit applies equally in highly specialised fields. In sectors like content marketing for life sciences or OB-GYN content marketing, the gap is almost never just a missing topic. It is a missing level of clinical or technical accuracy that generic content cannot provide. Identifying that gap requires reading the competitor content with domain knowledge, not just scanning a keyword report.

Moz has a useful perspective on using pillar pages in content strategy that is worth reading at this stage. The pillar and cluster model is a practical way to organise your gap-filling efforts so you are building topical authority systematically rather than publishing disconnected pieces.

Step 6: Build Your Content Gap Brief

A content gap analysis is only useful if it produces something actionable. That means turning your priority gap list into properly structured content briefs before anything gets written.

Each brief should include:

• The primary topic and target keyword
• The dominant search intent
• The top three ranking competitors for that keyword and what they cover
• The specific gaps or weaknesses in the existing ranking content
• The angle your piece will take to differentiate
• The content type (guide, comparison, checklist, case study)
• The internal links it should carry and receive
• The conversion goal, if any

That last point is one most content teams skip. If a piece of content has no defined conversion goal, you have no basis for evaluating whether it worked. That does not mean every piece needs a hard CTA. But it does mean you should know in advance whether success looks like email sign-ups, demo requests, time on page, or simply ranking for a topic that builds topical authority for your pillar pages.

HubSpot’s content creation templates are a reasonable starting point if you need a brief structure to adapt. The format matters less than the discipline of completing it before briefing a writer.

Step 7: Track and Revisit Regularly

A content gap analysis is not a one-time exercise. Competitors publish new content. Search behaviour shifts. Your own product or service offering changes. A gap that was low priority six months ago may be your most important opportunity today.

Set a calendar reminder to repeat the core steps of this process every quarter. You do not need to rebuild the full competitor map each time. A focused review of your priority topic clusters and a check on what new content your key competitors have published is usually enough to identify material changes.

Mailchimp’s guidance on content performance analysis is useful for the measurement side of this. Tracking how your gap-filling content performs over time gives you the feedback loop you need to refine your prioritisation criteria and get better at predicting which gaps are worth closing.

One thing I have learned from running this process across multiple industries is that the biggest gaps are rarely in obvious places. The most valuable gaps tend to be in the mid-funnel, where audiences are actively comparing options and forming preferences but most brands are either absent or publishing content that is too generic to build any real trust. That is where a well-executed manual content gap analysis pays back disproportionately.

It is also worth noting that analyst-influenced buying decisions in B2B markets create a specific kind of content gap. If analysts are framing your category in ways your content does not reflect, you are invisible in the conversations that matter most to enterprise buyers. That is a gap that keyword tools will never surface, but a manual review of analyst coverage alongside your content map will. Understanding how an analyst relations agency approaches content positioning can give you a useful lens for identifying those narrative gaps in your own programme.

The mechanics of a content gap analysis are straightforward. The judgment required to turn a gap list into a content programme that actually moves commercial metrics is not. That judgment comes from understanding your audience deeply, knowing your competitive position honestly, and being willing to deprioritise high-volume opportunities that do not serve your actual business goals. Most content teams are not short of ideas. They are short of a clear filter for which ideas deserve to exist.

For more on how content gap analysis connects to broader editorial planning, the Content Strategy & Editorial hub covers everything from content auditing to distribution, with a consistent focus on commercial outcomes rather than content for its own sake.

Copyblogger’s piece on SEO and content marketing is also worth reading alongside this process. It frames the relationship between search visibility and content quality in a way that reinforces why manual analysis produces better strategic decisions than automated gap reports alone.
