Claude Skills

Free skills for Claude built by Lil Big Things. Each one runs inside your Claude session: no external service, no subscription, no card.

We build these from the same playbooks we run for GEO and SEO clients. When we find a diagnostic or workflow worth automating, we package it and give it away.

Website SEO + AEO Audit

Audit any website for SEO and AI search. In one command.

A Claude skill that checks your site the way Google and AI answer engines actually read it, then hands you a prioritized, fix-it-first report. Nine phases, two disciplines: SEO substrate (crawlability through Core Web Vitals) and AEO readiness (AI crawler access, extractability, entity-welding, trust signals).
