Find Content Gaps for Your Course With Eurekaa AI

I get a version of the same email every couple of weeks. Someone has picked a course topic, usually something popular like “email marketing for beginners” or “how to start a Shopify store,” and they want to know if it’s a good idea. Almost every time, the honest answer is that the topic itself is fine. The problem is that fifteen other people already made a perfectly decent course on the exact same topic, covering the exact same ground, and there’s no reason for a student to pick the new one over the old ones.

That’s a different problem than “is there demand for this.” There’s obviously demand, that’s why fifteen courses exist. The real question is whether you can build something that covers what those fifteen courses are missing. That’s what content gap analysis is for, and it’s a genuinely different exercise from general course idea validation. If you haven’t read my piece on how to validate a course idea before you build it, that one covers the broader question of whether a topic is worth pursuing at all. This piece assumes you’ve already got a topic in mind, or a topic that’s already crowded, and walks through the specific process of using AI to find the angle nobody else is covering well.

I’ve used Eurekaa’s content gap analysis feature on a handful of course concepts over the past year, both for my own projects and for people I coach. In this guide I’ll walk through exactly how the feature works, the step by step process for using it properly, the mistakes that make people waste time chasing gaps that don’t matter, and how to turn whatever gap you find into an actual module list you can start building from.

Why “Just Another Course” Is the Most Expensive Mistake in Course Creation

Building a course takes real time. Depending on how thorough you are, you’re looking at anywhere from 40 to 150+ hours between outlining, recording, editing, and building out the platform side. If you spend that time recreating a course that already exists in five other forms, you’re not just wasting the hours, you’re also setting yourself up to compete purely on price or marketing spend against people who’ve had a two or three year head start building an audience around that exact topic.

This is the same lesson I try to hammer home with people looking at ecommerce, by the way. Picking a saturated product category with no differentiation is a slow way to burn cash, whether you’re building a course or a store. If you’re weighing course creation against other online business models, it’s worth reading my breakdown of how to actually pick a niche that has room for a new entrant, because the underlying logic is nearly identical. You’re not looking for zero competition. You’re looking for competition that has an obvious, exploitable weakness.

Content gap analysis flips the usual course planning process on its head. Instead of starting with “what do I know that I could teach,” you start with “what are the courses already ranking and selling on this topic actually leaving out, glossing over, or handling badly.” Then you build toward that gap specifically. It’s a more defensible way to compete because you’re not trying to out-market people, you’re offering something they genuinely can’t get elsewhere on the same topic.

Prerequisites Before You Start

You don’t need much to run this process, but a few things make it go faster and produce better results.

A candidate topic, even a rough one. This doesn’t need to be a finished course idea. “Something about freelance copywriting” or “a course on dog training for reactive dogs” is enough to start with. You’ll narrow it as you go.
An Eurekaa account. The Researcher plan runs $14 a month and is enough to run gap analysis on a handful of topics. If you’re planning to go further and actually build curriculum from the findings, the Creator plan at $16 a month (billed annually, $39 month to month) unlocks the AI Lesson Architect, which I’ll cover later in this guide.
Access to check two or three competing courses by hand. This is the step people skip, and it’s the one that catches mistakes an AI tool alone won’t. You don’t need to buy the courses. Landing pages, curriculum previews, and public reviews usually tell you enough.
Fifteen to twenty minutes of uninterrupted time. The tool itself is fast, but reading the output carefully and cross-checking it takes longer than people expect the first time through.

If you’re brand new to building any kind of online income and you’re still deciding whether a course, a service, or a product business makes more sense for you, my beginner’s guide is a good place to get oriented before you commit real time to any one path.

Step by Step: Running a Content Gap Analysis in Eurekaa

Step 1: Narrow your topic to something a gap analysis can actually work with

“Fitness” is too broad. “Marketing” is too broad. The tool needs something specific enough that it can pull a meaningful set of comparable courses and books, but not so narrow that there’s nothing to compare against. “Strength training for runners over 40” works. “Marketing” does not. Spend five minutes narrowing before you run anything, because a vague input gives you a vague, mostly useless comparison.

Step 2: Enter the topic and let Eurekaa pull the comparison set

Once you enter your topic, Eurekaa pulls together the existing courses, books, and other content already published on that subject and starts comparing what each one covers. This is the part that would otherwise take you hours of manually browsing course marketplaces, reading tables of contents, and skimming Amazon book previews. The tool does that legwork and organizes it into a comparison you can actually read in one sitting.

Step 3: Read the comparison output for coverage patterns, not just a list

Don’t just skim the list of what exists. Look at the pattern across it. If eight out of ten courses cover the same first three modules in roughly the same order, that’s not a gap, that’s the established curriculum everyone agrees is the baseline. The gaps show up in what’s consistently thin, rushed, or entirely absent across most or all of the existing content, not in what one single course happens to skip.

Step 4: Pull out the specific gaps the tool surfaces

Eurekaa’s gap output typically flags things in a few categories: topics that are missing entirely from the existing courses and books, topics that are mentioned but treated shallowly across the board, and areas where the existing content is outdated or based on old information. Write these down separately. A completely missing topic and a shallow topic call for different responses in your own curriculum, which I’ll get into in the outline section below.

Want to see this on a real topic before committing? Eurekaa’s Researcher plan starts at $14 a month, and running one or two gap analyses on your candidate topic is the fastest way to know if there’s actually room to build something different. Try Eurekaa’s content gap analysis →

Step 5: Cross-check the flagged gaps against real course reviews and Q&A

This is the step that separates a gap that’s real from a gap that’s a mirage. Pull up two or three of the top-ranked courses on your topic and read their reviews on the platform they’re sold on, plus any public reviews on sites like G2 or Capterra if the course lives on a learning platform that gets reviewed there. Search the course name plus “missing” or “wish it covered” or “doesn’t explain.” Students are usually blunt about what a course left out, and they’ve already done a chunk of your validation work for you for free.

Step 6: Look for gaps that show up more than once

A single review complaining about one missing topic could just be one person’s preference. A gap that Eurekaa’s comparison flagged, that also shows up in reviews of two different competing courses, and that also comes up in forum threads or Reddit posts about the topic, is a genuine pattern. Weight the gaps you act on by how many independent sources point to the same hole, not by which one sounds most interesting to you personally.

Step 7: Check search and community volume around the gap itself

Before you commit to building around a gap, spend ten minutes checking whether people are actually searching for or asking about that specific sub-topic. A quick search of the exact gap phrase, a look at related subreddits or Facebook groups for your topic, or a scan of “people also ask” boxes on Google will tell you fast whether this is something real people want answered or just an edge case nobody’s actually asking about.

Step 8: Run the gap through Eurekaa’s AI Lesson Architect (Creator plan and up)

If your account is on the Creator plan ($16 a month annually) or the Pro plan ($44 a month annually, which includes three seats if you’re working with a co-creator or a small team), you have access to the AI Lesson Architect. Feed it the gap you’ve identified and it will help translate that finding into a rough module and lesson structure, which saves you the blank-page problem of turning “here’s a gap” into “here’s a curriculum.”

Common Mistakes People Make With Content Gap Analysis

Confusing “nobody covers this” with “nobody wants this.” This is the single biggest mistake, and it happens constantly. A topic can be genuinely missing from every existing course for the simple reason that almost nobody is looking for it. Eurekaa’s comparison will tell you what’s missing from the existing content, but it won’t tell you on its own whether that absence is an opportunity or just a dead end. That’s why step 7 above, checking actual search and community demand around the gap, isn’t optional. Skip it and you risk building a beautifully differentiated course that answers a question nobody’s asking.

Ignoring reviews that already flag the exact gap you’re looking for. People do the AI comparison step and then skip the manual review-reading step because it feels slower and less impressive. That’s backwards. Real students leaving real complaints on a competing course’s reviews are some of the highest quality validation signal you can get, because they’re not hypothetical, they’re people who already bought a course on this exact topic and are telling you in their own words what it failed to deliver.

Chasing a gap that’s too narrow to build a course around. Sometimes what the tool surfaces is a real gap, but it’s genuinely a single-lesson topic, not a full course’s worth of content. Trying to stretch that into an entire curriculum results in padded, thin modules. If the gap is narrow, consider building it as a differentiated bonus module or a lead magnet inside a course that otherwise follows the standard structure, rather than trying to build an entire course around it.

Treating one gap analysis run as final. Course topics and the competitive landscape around them shift. A gap you find today might get filled by a competitor’s next course update in six months. Re-running the comparison periodically, especially before you finalize your curriculum and again before a major relaunch, keeps you honest about whether the gap you found is still actually a gap.

Only comparing against courses, and skipping books and free content. Some of the best gaps show up when you compare against books on the topic too, not just other paid courses. A topic that’s been covered thoroughly in books but never translated into a structured, practical course format is its own kind of gap, and it’s one that a course-only comparison would miss entirely.

Turning a Content Gap Into an Actual Course Outline

Once you’ve got a validated gap, the translation into curriculum works best in three passes.

First pass: map the standard baseline. Every crowded topic has an agreed-upon core curriculum that most of the existing courses cover in some form. Build that baseline into your outline first, even though it’s not your differentiator, because students expect it and skipping it makes your course look incomplete by comparison. This is typically 60 to 70 percent of your total module count.

Second pass: build the gap into its own dedicated section, not a footnote. If you bury your differentiator as a single bullet point inside an existing module, you lose the marketing and positioning value of it entirely. Give the gap its own module or its own clearly labeled section, and reference it explicitly in your course title, sales page, and marketing, because that’s the specific reason a student should pick your course over the five others covering the same baseline topic.

Third pass: weight your module order by gap severity. If the gap you found was something completely missing from every competing course, put it earlier in the curriculum where it’s more visible and harder for a student to miss. If it was something covered shallowly rather than entirely absent, you have more flexibility on placement since you’re deepening existing coverage rather than introducing something students have never seen addressed at all.

If you’re on the Creator or Pro plan, this is where the AI Lesson Architect earns its keep. Rather than staring at a blank outline document, you can feed it your validated gap plus your baseline topic list and get a starting structure to edit from, which is almost always faster than building the skeleton from scratch yourself.

Frequently Asked Questions

Is content gap analysis the same thing as course idea validation?
No, though they’re related and often done in sequence. Idea validation asks whether a topic has demand at all. Gap analysis assumes the topic already has demand, evidenced by existing courses selling on it, and instead asks what those existing courses are missing so you can build something differentiated rather than duplicative.

Do I need the Pro plan to run gap analysis, or does the cheapest plan work?
The Researcher plan at $14 a month gives you access to the core comparison and gap analysis feature, which is enough to identify gaps on your topic. You only need to step up to the Creator plan at $16 a month for the AI Lesson Architect that helps turn a gap into curriculum, or the Pro plan at $44 a month if you’re working with a team of up to three seats.

How many competing courses should I compare against before I trust a gap?
I’d want to see a gap show up across at least three to five existing courses or books on the topic, not just one. If only a single course is missing something and four others cover it well, that’s not really a market-wide gap, it’s just one competitor’s weak spot.

What if the tool doesn’t find any real gaps on my topic?
That happens, especially on topics that are extremely mature with dozens of well-built courses already covering every angle. If a genuine search turns up nothing, that’s useful information too. It usually means you either need to narrow your angle further (a specific sub-audience, a specific method, a specific outcome) or consider a less saturated adjacent topic instead.

Can I use this same process for a course I’ve already built and want to update?
Yes, and it’s actually one of the better uses of the feature. Running a gap analysis against current competitors periodically will tell you if new gaps have opened up since your last update, or if a competitor has closed the gap you originally built your course around, which is a signal that your curriculum needs refreshing to stay differentiated.

Next Steps

The fastest way to know whether this is worth your time is to run it on the actual topic you’re considering rather than reading about it in the abstract. Pick your candidate topic, run it through Eurekaa’s comparison and gap tools, then spend the extra fifteen minutes cross-checking against real reviews before you commit to a curriculum. I run Ecommerce Paradise, and the pattern I see over and over with the people I work with is that the ones who do that manual cross-check step almost always end up with a stronger, more specific angle than the ones who trust the AI output alone.

If you decide a course isn’t the right fit for you after all, or you want to pair course income with a physical product business, that’s a path I cover extensively as well. My guide to what high-ticket dropshipping actually is and my step by step breakdown of how to find suppliers for high-ticket products are both good starting points if you want to compare the two models before picking one.

And if you do end up building a store alongside or instead of a course, don’t skip the legal setup step. My guide on business formation for high-ticket dropshipping covers what to set up before you start taking real money through the business.

If you’d rather have someone build the store side for you while you focus on course content, my done-for-you service handles that.

And if you want direct feedback on your course or business plan as you go, that’s exactly what my coaching program is built for.
