I'm trying to check the core web vitals of my website but found out that it also checked my subdomains. I've checked PageSpeed Insights and GSC but couldn't find ways to deal with this.
How can I avoid that?
Core Web Vitals as reported by the Chrome User Experience Report (CrUX) are given by Origin and URL (where available) in PageSpeed Insights, and by page grouping of URLs in Google Search Console. They do not include subdomains in this in either of these tools. Can you explain why you think it does?
