Claude SEO v1.9 Adds 6 Audited Community AI Skills
Open-source Claude SEO v1.9 integrates 6 community-built skills—semantic clustering, SXO detection, drift monitoring, e-commerce schema, international localization, and gamified learning—boosting total to 23 skills, 17 agents, 30 scripts at 85/100 security score.
Cluster Keywords into Pillar Pages Using SERP Overlap
Semantic Topic Clustering analyzes SERPs for a seed keyword to group URLs ranking across multiple queries, identifying pillar pages (high overlap) versus supporting content for hub-spoke architecture. Input keywords; get interactive SVG maps showing clusters without paid tools like Ahrefs. Lutfiya Miller's skill (challenge winner) enables precise content planning: pillar pages target broad queries, clusters feed topic support, reducing keyword cannibalization and improving site structure.
Detect Page Mismatches and Track Changes to Fix Ranking Drops
Search Experience Optimization (SXO) reverses SERP analysis—examines user needs (e.g., comparison lists) against your page type (e.g., product page) to flag intent gaps, persona mismatches, and why rankings fail. Florian Schmitz's tool scores pages and suggests fixes.
SEO Drift Monitor baselines page elements (titles, metas, headings, schema) across 17 rules in 3 severity levels, then generates HTML diff reports on changes—like dev tweaks causing drops—enabling Git-style history tracking. Dan Colta's implementation catches 'invisible' issues post-update, restoring rankings faster than manual audits.
Automate E-commerce Schema and International Localization
E-commerce SEO auto-detects WooCommerce/Shopify setups to generate product/catalog schema, pull Google Shopping data, and fetch Amazon competitor pricing/intel—streamlining rich results and traffic. Matej Marjanovic's skill handles stores without custom coding.
International SEO Enhanced applies cultural profiles for DACH (Germany/Austria/Switzerland), France, Spain, Japan: locale rules for formality, currency, compliance; scores content parity across languages; validates hreflang/formats. Chris Muller's tool goes beyond tags to real signals, boosting global rankings.
