SEO Content Gap Audit

Find content gaps and decay using Ahrefs MCP data. Stack-agnostic. Produces a roadmap of create, update, merge, and prune actions across the existing content catalog and identified topic gaps.

When to use

Planning the next quarter or half of content investment
Refreshing a stale or underperforming content catalog
Building topical authority in a target space
Identifying decaying pages before they tank traffic
Audit prep before a major site redesign or migration
Diagnosing why content investment is not driving organic growth

When NOT to use

Pure keyword research (use seo-keyword)
Competitor keyword gap (use seo-keyword-gap-audit)
Single-page optimization (use seo-onpage)
Pure prune-and-redirect decisions (use seo-content-audit)
New site planning with no existing content (use content-strategy)

Required inputs

Target property and content scope
Competitor set (3-5 properties with comparable content depth)
Target topics or pillars (if defined)
Existing content inventory with URLs, primary topics, publish dates
Performance data (organic clicks per page, ranked keywords per page)
Confirmation Ahrefs MCP is connected

The framework: 4 categories of content opportunity

Every content opportunity falls into one of four categories. Different categories need different actions.
