Google: Lighthouse Scores Do Not Affect Google Search

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.

Here is John’s tweet:

Lighthouse scores do not affect Google Search.

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. https://t.co/yCoaYduHU4

Code obfuscation is a strong smell that a dev is trying to hide something dishonest, and is likely hurting your business. Fire that team.

Google has often downplayed Lighthouse metrics for SEO over the years.

This thread on Twitter is super interesting, here are some responses that caught my eye:

Google is partly to blame for this IMO. They’ve created such hysteria with their CWV update that site owners are scrambling to get a perfect Lighthouse scores in order to stay relevant, and so far these shady “SEO” tools seem to be working…

Malte Ubl is a Googler:

Most SEOs don’t understand the lighthouse scores don’t directly relate to your page speed scores even prior to the page experience roll out.
