How to Do a Content Gap Analysis (Step-by-Step)
What Is a Content Gap Analysis?
A content gap analysis compares your keyword coverage against competitors to find valuable keywords where they rank but you do not. These gaps represent traffic you are leaving on the table.
It is one of the highest-ROI SEO activities because you are targeting keywords with proven demand and existing competitor content you can improve upon.
Step 1: Select Your Competitors
Choose 3-5 direct SEO competitors. These are sites that rank for the keywords you want, not necessarily your business competitors.
To find them, search for your top 10 target keywords and note which domains appear most frequently. Those are your SEO competitors.
Step 2: Export Keyword Data
For each competitor, pull their ranking keyword data using an SEO tool. Export all keywords where they rank in the top 20. You will end up with large lists — that is expected.
Step 3: Find the Gaps
Compare the keyword lists to find:
Keywords all competitors rank for but you do not
These are the most critical gaps. If every competitor targets a keyword, there is clearly demand and opportunity.
Keywords 2-3 competitors rank for
Still high priority, especially if these competitors are the strongest in your niche.
Keywords only one competitor ranks for
Lower priority but could represent untapped opportunities that other competitors have also missed.
Step 4: Categorize and Prioritize
For each gap keyword, evaluate:
- Search volume: Higher volume gaps deserve more attention
- Keyword difficulty: Start with gaps you can realistically rank for given your current authority
- Search intent: Match the keyword to the right content type
- Business relevance: Does this keyword attract potential customers?
- Content effort: How much work is needed to create competitive content?
Create a scoring matrix. A keyword with 1,000 monthly searches, low difficulty, commercial intent, and high relevance scores higher than a keyword with 5,000 searches but informational intent and low relevance.
Step 5: Map Gaps to Content Plan
Group related gap keywords into content topics. A single comprehensive article can often target 10-20 related gap keywords.
Assign each content piece:
- Target primary keyword
- Supporting keywords
- Content format (guide, comparison, tutorial, etc.)
- Target word count
- Internal link opportunities
Step 6: Execute with Quality
This is where most gap analyses fail. Teams identify the gaps, plan the content, and then produce mediocre articles that do not outperform existing competitor content.
For each gap, ask: what can I create that is genuinely better than what currently ranks? Better means more comprehensive, more current, better designed, with more original insights, or serving the intent more effectively.
Step 7: Monitor Results
Track new content performance weekly for the first three months:
- When do pages get indexed?
- How quickly do they enter the top 100? Top 20? Top 10?
- Which gap keywords are you capturing?
- What is the traffic trajectory?
Use this data to refine your gap analysis process. You will learn which types of gaps convert to rankings most reliably for your site.
Running Gap Analysis Quarterly
Repeat this analysis every quarter. As you close existing gaps, new ones emerge because competitors publish new content and search trends evolve. Make it a recurring process, not a one-time project.
