Ever wonder why your competitors outrank you? The answer might be hiding in the keywords they rank for—but you don’t. That’s where the Ahrefs Content Gap Tool comes in—a goldmine for SEO professionals, marketers, and content creators looking to uncover untapped traffic potential.zS
What Is the Ahrefs Content Gap Tool?
The Content Gap Tool is a feature in Ahrefs that compares your site to your competitors’ and shows keywords they rank for that you currently do not.
What Makes It Powerful
It highlights real search terms, complete with volume and difficulty metrics, that represent clear opportunities to improve your SEO strategy.
Why Keyword Gaps Matter for SEO
Understanding Missed Opportunities
If you’re not targeting the same keywords as your competitors, you’re potentially missing out on traffic they’re currently enjoying.
Outranking Your Competitors
By identifying these content gaps, you can create optimized content to leapfrog over your competition on the SERPs.
Setting Up the Ahrefs Content Gap Tool
Where to Find It
In Ahrefs, go to Site Explorer, input your domain, and look for the Content Gap option in the left-hand menu under “Organic Search.”
Inputting Your Site and Competitors
Add your website in the “Show keywords that the below targets rank for, but the following doesn’t” section. Then list 2–3 of your top competitors in the fields above.
Step-by-Step: How to Use the Content Gap Tool
Step 1: Identify Your Competitors
These should be sites ranking for similar content, not necessarily your business rivals.
Step 2: Input URLs
You can compare full domains (domain.com) or specific URLs if you’re working on page-level strategy.
Step 3: Analyze Keyword Differences
Click “Show keywords” and Ahrefs will display a list of keywords your competitors rank for that you don’t.
What to Look for in the Results
SERP Intent – Make sure the keyword aligns with your type of content (blog, product, service)
Keyword volume – Choose terms with real search demand
KD (Keyword Difficulty) – Prioritize low to medium KD for faster wins
Prioritizing Keyword Opportunities
Relevance to Your Site
Not all keywords make sense—filter out the ones that don’t match your offerings.
Ranking Potential
Look for keywords with moderate volume and low Ahrefs KD (<30) to rank quickly.
Traffic Value
Don’t just chase volume. Keywords that lead to conversions or email signups are more valuable.
Using the Data to Create Content
Build content silos that boost authority in your niche
Map new keywords to existing content or create new pages
Group related keywords into topic clusters
Examples of Content Gap Insights in Action
Blog Post Topic Discovery
If a competitor ranks for “best time to post on Instagram” and you don’t, write a comprehensive post optimized for that phrase.
Service Page Keyword Expansion
If they rank for “local SEO services near me” and you don’t, update your service page or create a location-based landing page.
Tips for Better Competitor Selection
Avoid mega-sites (like Wikipedia or Amazon)—they may skew the data
Use sites with similar or slightly higher DR
Choose competitors ranking for topics you also cover
Using the Tool for Local SEO and Niche Sites
You can discover:
Niche-specific questions (e.g., “how to dry age beef at home”)
Perfect for smaller businesses or content creators in specific verticals.
Local keywords (e.g., “best NYC plumber”)
Mistakes I Made Using the Ahrefs Content Gap Tool (So You Don’t Have To)
I love the Content Gap Tool—but I’ve messed it up a few times. Here’s what I learned:
I copied other sites too closely
Big mistake. I saw what my competitors ranked for—and just tried to copy it.
But Google doesn’t want the same content.
It wants better.
Now, I ask: “How can I say this in a new or stronger way?”
Google talks about this in their helpful content guide. Worth a read.
I added too many competitors
I used to drop 5 or 6 websites into the tool at once.
Guess what? It got messy.
Too many results. Too many directions.
Now, I stick to 2–3 real competitors.
People who write like me. Sell like me. Rank where I want to rank.
I ignored search intent
Here’s where I really blew it:
I tried ranking blog posts for keywords that were meant for product pages.
For example: “Buy noise-canceling headphones”
That keyword means someone’s ready to shop—not read a blog.
You have to match what people actually want.
This guide from Moz helped me get it straight.
