SEO Content Gap Analysis

Find the topics and search intents your competitors cover and you don't — then turn the gaps into a prioritized content plan.

What it does

Compares the content footprint of a site against one or more competitors to surface gaps: missing topics, uncovered search intents, absent content formats, and underserved funnel stages. It then prioritizes the gaps into a content plan mapped to the buyer journey. This is an editorial/strategic gap analysis from public pages — it complements (not replaces) a keyword tool with volume data.

When to use this skill

• "Find content gaps vs <competitor>."
• "What topics should we be writing about?"
• "Do an SEO gap analysis between our blog and theirs."
• "Build a content plan to outrank <competitor>."

Inputs needed

• Required: the user's site/blog URL and at least one competitor URL.
• Helpful: the target audience and ICP, the product's key topics, and any keyword data the user already has (volumes, current rankings) — fold it in if provided.
• If no competitor is given, ask for 1–3, or infer likely ones and confirm.

Method

1. Inventory each site's content — crawl the blog/resources/glossary of the user's site and each competitor. For each, list topic clusters and notable pages (pillar pages, guides, tools, glossaries, comparison pages).
2. Classify by intent & funnel stage — tag content as:
   • Intent: informational, commercial, transactional, navigational.
   • Stage: TOFU (awareness), MOFU (consideration), BOFU (decision).
3. Build the coverage matrix — topic clusters × sites; mark who covers what.
4. Identify the gaps:
   • Topic gaps — clusters competitors cover that the user doesn't.
   • Intent gaps — e.g. competitors have BOFU comparison/alternative pages and the user has only TOFU blog posts.
   • Format gaps — missing tools, templates, glossaries, comparison pages.
   • Depth gaps — topics the user covers thinly vs competitor pillar content.
5. Prioritize — score each gap by relevance to ICP, business value (funnel stage), and effort. Favor BOFU and high-relevance gaps for quick wins.
6. Produce a content plan — recommended pieces, each with target topic, intent, format, funnel stage, and the angle that beats existing results.

Output format

## TL;DR
- Where the biggest gaps are, and the 3 pieces to publish first.

## Coverage matrix
| Topic cluster | You | Comp A | Comp B | Gap type |
|---------------|-----|--------|--------|----------|

## Gaps by type
- Topic gaps: · Intent gaps: · Format gaps: · Depth gaps:

## Prioritized content plan
| # | Topic / title angle | Intent | Funnel stage | Format | Why (gap) | Priority |
|---|---------------------|--------|--------------|--------|-----------|----------|

## Quick wins (BOFU / high-relevance first)

Quality bar

• Be explicit that this is an editorial gap analysis from visible content; if the user has keyword volumes/rankings, integrate them — otherwise don't invent search volumes or traffic numbers.
• Every recommended piece maps to a real observed gap and a funnel stage.
• Prioritize by business value, not just volume of missing posts.

Common mistakes to avoid

• Listing every competitor post as a "gap" without checking relevance to the ICP.
• Ignoring BOFU comparison/alternative pages (often the highest-value gaps).
• Recommending topics the user already covers well (no depth check).
