Content Gap Analysis, Explained
Content gap analysis is the cheapest form of content strategy. Instead of guessing what to write next, you let the SERP show you exactly where competitors are winning traffic and you're not. This guide walks through the workflow end-to-end.
What a content gap actually is
A content gap is any topic where one or more competitors rank in the top 10 and your domain doesn't appear at all. Each gap represents proven search demand that's currently bypassing your site.
Step 1 — Pick the right comparison set
Use 2–4 SEO competitors (the domains that show up most often across your target keywords). Adding too many competitors creates a noisy gap list that's impossible to action.
Step 2 — Run the comparison
Use the Competitor Analyzer to pull each competitor's ranking keywords. Cross-reference against your own ranked keywords. Anything they rank for and you don't is a candidate gap.
Step 3 — Filter for relevance and intent
Not every gap is worth filling. Drop terms that don't match your business, queries with no commercial value, and topics outside your topical authority. A 100-line gap list usually shrinks to 20–30 high-value targets.
Step 4 — Prioritize by impact
Score each remaining gap by (Volume × Intent value) ÷ Difficulty. Tackle the top decile first. The remaining 70–80% of the list becomes your editorial backlog for the next two quarters.
Step 5 — Build, ship, track
Brief and publish content for the top gaps, then track rankings to confirm the gap is closing. Re-run the analysis quarterly — closed gaps and new ones constantly emerge.
An example of a real gap analysis
A B2B SaaS team compared themselves against three competitors and surfaced 47 gap keywords. Filtering for commercial intent and topical fit cut the list to 12 — every one of which could be served by a comparison or alternatives page. Six months later, the team owned 9 of the 12.

Frequently asked questions
How often should I run content gap analysis?
Quarterly for most sites. Faster-moving niches (SaaS, ecommerce) benefit from monthly re-runs.
How many competitors should I compare against?
Two to four. Beyond that, the gap list becomes too noisy to prioritize cleanly.
What if I don't rank for anything yet?
Then every keyword your competitors rank for is technically a gap. Filter aggressively for commercial intent and start with the top 10 highest-value terms.
Should I always create new pages for gaps?
Not always. Some gaps are best served by expanding an existing page rather than building a new one. Check your current rankings first.
