Verify it doesn't block important pages. Reference: [robots.txt spec](https://developers.google.com/search/docs/crawling-indexing/robots-txt) +2. **Sitemap** — Locate the sitemap (or sitemap index). Verify all important pages are listed and no dead URLs are included. Reference: [Sitemap guidelines](https://developers.google.com/search/docs/crawling-indexing/sitemaps/large-sitemaps) +3. **Meta robots tags** — Check for unintended `noindex` or `nofollow` directives on pages that should be indexed. + +Note: robots.txt and sitemaps are often auto-generated. If so, check the generator config rather than the output file. + +## Step 5 — Audit broken links and canonicalization + +Reference: [What is canonicalization](https://developers.google.com/search/docs/crawling-indexing/canonicalization) + +1. Check all internal links resolve to valid pages (no 404s). +2. Verify `<link rel="canonical">` tags are present and point to the correct URL. +3. Check for duplicate content accessible via multiple URLs (with/without trailing slash, www vs non-www). +4.

Verify the `<meta name="viewport">` tag is present and correctly configured. +2. Check that content is identical between mobile and desktop (mobile-first indexing requires this). +3.

Check font sizes are readable without zooming (min 16px body text). + +## Step 7 — Audit structured data + +Reference: [Structured data guidelines](https://developers.google.com/search/docs/appearance/structured-data/sd-policies) + +1. Check for existing JSON-LD `<script type="application/ld+json">` blocks. +2. Verify the structured data matches the page content (no misleading markup). +3. Add missing structured data where appropriate: + - **Organization/Person** on the homepage + - **Article/BlogPosting** on blog posts (with author, datePublished, dateModified) + - **BreadcrumbList** for navigation + - **FAQ** for pages with question/answer content +4. Validate JSON-LD syntax is correct. + +## Step 8 — Audit social media cards + +Reference: [Implementing Social Media Preview Cards](https://documentation.platformos.com/use-cases/implementing-social-media-preview-cards) + +Check every page template includes: + +**Open Graph (Facebook/LinkedIn):** +- `og:title`, `og:description`, `og:image`, `og:url`, `og:type` + +**Twitter Card:** +- `twitter:card`, `twitter:title`, `twitter:description`, `twitter:image` + +Verify `og:image` dimensions are at least 1200x630px.

As an example, this claim isn't valid as content unless it links to an authority that found this through research + +> Research shows teams with strong DevEx perform 4-5x better across speed, quality, and engagement + +Search for the authoritative URL and add a link to the URL. If it is not available, change the claim to something that can be substatiated. + +## Step 10 — Audit Design Compliance + +Read the design system docs and view the design screens in the designsystem folder. + +## Step 11 — Test with Playwright + +Build and run the website locally using `make website-run` (or the project's equivalent dev server command). + +**Desktop tests (1280x720):** + +1. Navigate to the homepage — take a screenshot. +2. Navigate to each major section — verify pages load without errors. +3. Check the browser console for JavaScript errors. +4. Verify all navigation links work. + +**Mobile tests (375x667, iPhone SE):** + +1. Resize the browser to mobile dimensions. +2. Navigate to the homepage — take a screenshot. +3. Verify the layout is responsive (no horizontal overflow, readable text). +4. Test navigation menu (hamburger menu if applicable). + +If any page fails to load or has console errors, fix the issue and retest. + +## Step 12 — Report findings + +Summarize the audit results: + +``` +## Website Audit Report + +### Fixed +- [List each issue fixed with file and line reference] + +### Warnings (manual review needed) +- [Issues that need human judgment] + +### Passed +- [Areas that passed audit with no issues] + +### Screenshots +- [Reference Playwright screenshots taken] +``` + +## Rules + +- **Operate autonomously — never stop to ask the user questions.** Make the reasonable default decision, record it in the report, and keep going to completion. +- **Fix issues directly** — don't just report them.
