Useful Claude Skills for SEO and ASO in 2026

A short post sharing two Claude Skills worth bookmarking if you ship websites, portfolios, or mobile apps. One focuses on SEO, the other on ASO (App Store Optimization). Both are free, both run inside Claude Code.

A Quick Note on SEO in 2026

Search is no longer just Google. There is now a second layer most sites do not optimize for: AI search engines like ChatGPT, Perplexity, Bing Copilot, and Claude - all of which recommend sites and cite sources. This new layer is called GEO (Generative Engine Optimization), and it sits next to traditional SEO.

For portfolios, agency landing pages, and product sites, optimizing for both is becoming the default expectation.

Claude SEO: Full-Site Audits From the Terminal

Claude SEO is an open-source skill that turns the terminal into an SEO consultant. The pitch is simple: run /seo audit [url] and get back a 0-100 health score with a prioritized action plan in minutes.

What it covers:

Technical SEO (crawlability, indexability, Core Web Vitals)
Content quality scored through the E-E-A-T framework
Schema markup detection plus auto-generated JSON-LD
Local SEO and Google Business Profile audits when relevant
AI search optimization (GEO) for ChatGPT, Perplexity, Bing Copilot
Industry-aware recommendations (SaaS, local service, e-commerce, publisher, agency)
Optional integration with Ahrefs and Semrush MCPs for richer data

It is MIT-licensed, has thousands of GitHub stars, and runs nine parallel agents under the hood for the audit. Worth bookmarking before your next launch.

Claude Skills for Mobile (ASO)

If you ship mobile apps, Code With Beto put together a curated list of five Claude Skills focused on the non-code side of shipping:

ASO Audit (by appeeky) - health check on your App Store listing with concrete fixes
Apple Search Ads - paid acquisition and bid strategy
App Store Preflight - catches rejection-prone issues before you submit a build
App Icon - icon design and conversion testing
UI Skills - polish on the parts of the app that convert visitors into installs

The whole list is framework-agnostic - works the same whether you are on Expo, vanilla React Native, Flutter, or native. The focus is on listings, screenshots, icons, and metadata - the parts most developers tend to under-invest in.

Why Skills Like These Matter

Claude Skills are not a replacement for SEO or ASO specialists - real experts still win on enterprise-scale work and competitive markets. What these skills do is bring the 80/20 within reach of solo developers and small teams: the parts of an audit you would normally skip because they were tedious, expensive, or required learning yet another dashboard.

If you have a launch coming up, both of these are worth 20 minutes of your time:

Claude SEO - web SEO and GEO audits
Best Claude Skills for mobile development - mobile / ASO

Free, open source, and immediately useful. That is a rare combination.
