2 SEO questions:
1) a CDN means "thousands of websites on one IP address". Google doesn't like it UNTIL it knows, the IP belongs to a well-known CDN like cloundfront/cloudflare etc. Please comment?
2) An A/B test might look like "cloaking" to googles. How exactly do you run it? I assume, not in parallel, but "variation A then variation B" - correct? If yes, does it mean I have to leave the website UNTOUCHED for 21 days so the test results are not distorted by my other activities? (adding new content, internal links etc)
