Homepage does not serve Markdown via content negotiation
Serve a Markdown representation of your pages when agents request "Accept: text/markdown". Agents like Claude Code and Cursor ask for it, and Markdown cuts token usage by ~80% vs HTML. Cloudflare ("Markdown for Agents") and Vercel can enable this without code changes.
No <link rel="alternate" type="text/markdown"> fallback found on the homepage
If you cannot enable content negotiation, advertise a Markdown version with <link rel="alternate" type="text/markdown" href="/index.md"> so agents can discover it.

No core AI crawlers explicitly configured
Add User-agent entries for core AI crawlers in your robots.txt. For each crawler, add: User-agent: <name> followed by Allow: / on the next line.
Sitemap directive present
No Content-Signal directive found (optional)
Declare how crawlers may use your content after access with the Content Signals Policy, e.g.: Content-Signal: search=yes, ai-train=no. Known signals: search, ai-input, ai-train. Generate yours at contentsignals.org.

Response compressed with Brotli (br)
Cache validator present (Last-Modified)
Conditional request returned 200 instead of 304 Not Modified
The server advertises a cache validator but does not honor If-None-Match / If-Modified-Since. Configure it to return 304 when the validator matches, so crawlers avoid re-downloading unchanged pages.
Homepage is on the large side (558.2 KB decompressed)
Consider trimming inlined payloads to reduce crawl cost.
Server-rendered content detected (491 words, 5376 chars of visible text)
Low text-to-markup ratio (0.9%)
A very low text-to-markup ratio is a typical SPA-shell symptom. Inline more content directly into the HTML response.
Semantic landmarks present (main, section, header, footer, nav)
Single <h1> heading: "Welcome to IKEA Global!"
34/34 <img> tags have alt attributes
Site is served over HTTPS
HTTP requests redirect to HTTPS
