Together
What these skills do together
Audit: Full-site SEO audit
One URL in, a health score and an action plan out. Run it first so the rest have something to fix.
Read what Google does with it: Search Console performance review
Search Console through the API, two windows, three lists: where a revision beats a new page, where a title loses clicks, where demand moved.
Fix the platform: Technical SEO audit
Crawlability, indexability, rendering and the crawler table. The findings here decide whether anything else is visible.
Score the money pages: Product-page SEO scoring
Product pages and their schema, the surface a store earns from.
Mark up: Structured data (JSON-LD)
JSON-LD for what the pages contain, validated before deploy.
Scale, if the data supports it: Programmatic SEO planner
Only with data that is yours; the skill says so before you build.
Limits
What a skill cannot replace
Instructions alone do not see your Search Console, your CrUX field data or your competitors’ rankings. Retrieval needs an authorised connection: the Search Console pack on this shelf includes one, read-only, and the toolkits shelf has two more. An audit run without a connection is a read of the HTML, and a good one; it is not a measurement of what Google is doing with the site.

The service behind this shelf: what is run, how it is measured, and what it costs.

From our guides
The method behind the skills, with the measurements.
- How to run an ecommerce SEO auditMost audit checklists mix one thing Google publishes a threshold for with fifty things it does not. Here is the difference, and the ecommerce-only section that generic audits leave out entirely.
- Ecommerce SEO: What to Fix and in What OrderEvery ecommerce SEO guide is the same four headings. Across three major storefront platforms the audit category named SEO scores 92 to 100 and separates nobody. Here is where the work that is left sits.
- Shopify SEO: which technical decisions the platform already madeShopify decides much of your technical SEO by default and documents the two problems it creates. Plus eleven public robots.txt files read on one day, serving two different Shopify defaults.
- What are Core Web Vitals? Thresholds and counting rulesThe three metrics, the three published thresholds, and the three counting rules that decide whether a store passes. Plus what the numbers look like by ecommerce platform.
- B2B SEO strategy: plan for small terms and long timelinesThere is no B2B ranking algorithm. What changes is the size of the terms, the number of people deciding, and how long a page takes to pay back. Each of those can be put into numbers.
- SaaS SEO strategy: name the conversion firstAcross 86 SaaS clients from Q1 2022 to Q3 2025, First Page Sage measured organic trial-to-paid rates of 18.2 percent without a card and 48.8 percent with one.
Questions
Questions people ask before installing
Can Claude Code help with SEO?
For the parts that are reading and structure, yes, and the five skills here crawl, score, validate and plan. For the parts that are measurement (rankings, field Core Web Vitals, indexation), only with a data connection, and two of the toolkits on this site provide it.
Which one do I install first?
seo-audit if you have a site and a question; schema if you have one page to mark up; programmatic-seo if you are deciding whether to build a page set.
Do these work on Shopify?
Yes. They read rendered HTML, so the platform does not matter, and seo-ecommerce is written for product pages.
