Master SEO with Authority Mark: AI Skill for Claude & Codex

This AI skill leverages the Authority Mark method to evaluate SEO keyword difficulty, helping developers assess their website’s competitive standing directly from the current SERP results.

What this skill does

  • Analyzes live SERP data for a specific keyword query.
  • Collects Ahrefs Domain Ratings (DR) for the top organic ranking domains.
  • Compares the user's domain rating against these top-ranking domains.
  • Identifies the first top-10 ranking position where the user's DR is higher than that of the competing sites.
  • Provides an actionable threshold for entering the SERP based on current authority openings.

Who it is for

This skill benefits developers and SEO teams using AI coding agents like Claude Code, Cursor, and Codex, aiming to better understand and leverage SEO keyword difficulty metrics.

Use cases

  • Developers optimizing websites for search visibility by actively identifying authority openings in SERPs.
  • Teams prioritizing SEO efforts based on concrete domain authority comparisons rather than generalized difficulty scores.
  • Businesses assessing new keyword opportunities with a focus on their competitive standing against existing top-ranking websites.

Technical details

  • Integrates with Ahrefs to fetch Domain Ratings (DR) for competing domains.
  • Employs AI-supported agent capabilities within Claude Code and Codex environments.
  • Relies on publicly available information from live SERP assessments.

Note: Users must comply with the terms of use of each SERP data source. This skill targets publicly available information only and does not bypass authentication or CAPTCHA.

Ran it on a client's Google Ads account and it flagged wasted spend we'd been missing for months. Paid for itself on day one.

We finally caught broken conversion tags before launch instead of after. The pre-launch checklist alone is worth the price.

Dropped it into Claude Code and my LCP went from 4.1s to 1.9s in an afternoon. It explains every fix it suggests, so I actually learned something too.
