Website SEO Setup

Context

SEO infrastructure is invisible to users but determines whether search engines can find, understand, and rank the site. Getting it wrong at launch means weeks of lost indexing time. This skill ensures every technical SEO element is configured correctly before the site goes live.

Procedure

1. Write title tags for every page using the pattern: [Primary keyword] — [Brand]. Keep under 60 characters. Homepage: [Brand] — [Value proposition]. Inner pages: [Page topic] — [Brand].
2. Write meta descriptions for every page: summarize the page content with a call-to-action in 120-160 characters. Include the primary keyword naturally.
3. Set canonical URLs: every page points to its own canonical (self-referencing). Use absolute URLs with the production domain. Handle trailing slashes consistently.
4. Configure robots.txt: allow all public pages, block admin/API routes, reference the sitemap URL.
5. Generate the XML sitemap: include all public pages with lastmod dates, priority hints, and change frequency. Exclude non-indexable pages (404, redirects, paginated).
6. Implement structured data (JSON-LD): Organization schema on homepage, WebPage on all pages, BreadcrumbList on inner pages. Add product-specific schemas where applicable (FAQ, HowTo, SoftwareApplication).
7. Configure Open Graph and Twitter Card tags: og:title, og:description, og:image (1200×630px), og:url, twitter:card (summary_large_image).

## QA Rubric (scored)

- Metadata uniqueness (0-5): every page has distinct title and description.
- Technical accuracy (0-5): robots.txt, sitemap, and canonicals are correctly configured.
- Structured data validity (0-5): JSON-LD passes Google Rich Results Test.
- Launch readiness (0-5): all checklist items verified before going live.

## Examples (good/bad)

- Good: "Title: 'AI Marketing Platform — LemuriaOS' (32 chars). Description: 'Orchestrate 75 AI marketing specialists across SEO, paid, and social. Start with a free scan.' (97 chars). Canonical: https://https://lemuriaos.ai/. JSON-LD Organization with logo, sameAs, and description."
- Bad: "Title: 'Home'. Description: empty. No canonical. No structured data. robots.txt blocks everything. No sitemap."

## Variants

- Blog-heavy mode: includes Article schema, author markup, and paginated sitemap for content-heavy sites.
- E-commerce mode: includes Product, Offer, and AggregateRating schemas, plus product-specific OG tags.
