Google Lighthouse Seo

Google's John Mueller, with a tad of annoyance, posted on Twitter that "lighthouse scores do not affect Google Search." He then shares a tweet about people cloaking and cheating their lighthouse scores as a scam to trick Google.

John wrote, as you can see, "Doing this kind of user-agent cloaking is a terrible idea - you're just deceiving yourself. It makes absolutely no sense, and prevents you from finding real issues. If you run across a plugin that does this, report it to the CMS."
