The Best SEO Skills for Claude Code
SEO skills are easy to write badly, because the advice is public and the hard part is the diagnosis. These seven are scored by whether they produce a finding you did not already have.
Our marketing category is the second-largest at 119 skills, and SEO is its densest sub-cluster. The skills split into audits (find what is broken), production (make something that ranks), and research (find what to target).
Audits
technical-seo-checker — 9.3 · Marketing
Crawlability, indexability, sitemap validity, canonical consistency, redirect chains. The most mechanical of the group and the most valuable, because technical problems are invisible from the outside and often decisive.
on-page-seo-checker — 9.2 · Marketing
Diagnoses why a single page is not ranking: title, headings, internal links, content depth, intent match. Narrower than the technical audit and aimed at a specific URL rather than the whole site.
Production
serp-markup-builder — 9.4 · Marketing
Meta tags, title tags, and descriptions written for the SERP rather than for the page. The highest-scoring SEO skill in the directory, and the one with the clearest output: strings you can paste.
page-play-builder — 8.9 · Marketing
Builds programmatic SEO pages — the template-plus-data pattern that produces hundreds of long-tail pages. Powerful and risky in equal measure: programmatic pages are also the fastest way to create thin content, and search engines are good at spotting it.
Research
search-term-miner — 8.6 · Marketing
Mines your existing search terms for new keyword opportunities. Works from data you already own (Search Console), which makes it more grounded than generic keyword research.
keyword-research — 8.6 · Marketing
Finds keywords and prioritizes by search intent. The conventional entry point; useful mainly for breadth.
serp-analysis — 8.6 · Marketing
Maps SERP features and what currently occupies the results for a query. Answers "what would I have to beat" rather than "what should I write".
The order that actually works
The temptation is to start with keyword research. In practice, for a site that is already live, the order is: technical audit → on-page audit of existing pages → then keywords. Keyword research on a site that cannot be crawled or indexed produces a plan you cannot execute.
That ordering also matches what we see in our own data: the pages that get impressions are existing long-tail pages, not new ones. Fixing what is already there beats adding more.
