1. What's your TTFB (Time to First Byte)?

Measure it at webpagetest.org or in Chrome DevTools → Network → first row → Time. It's the #1 hosting indicator.

2. What type of hosting do you use?

Hosting is the #1 speed lever according to the corpus. Not the CDN, not image optimization — the server.

3. Does your server return a 200 on the final URL (no redirects)?

Google says: 'always use the final URL'. Redirects add latency and can confuse the crawler.

4. Does your robots.txt block AI bots (GPTBot, ClaudeBot)?

CUBO-09: 5.9% of 140M sites block GPTBot without knowing. Cloudflare enables it by default.

5. Have you implemented IndexNow?

CUBO-09: IndexNow is a ping to Bing/Yandex. 'Google is not in it'. 32-digit key, 10,000 URLs/day. Useful for Bing, irrelevant for Google.

6. Does your page use server-side rendering (SSR)?

CUBO-09: 'Gemini and Copilot can render JS, but ChatGPT cannot'. If your site is an SPA without SSR, ChatGPT sees an empty page.
