Quick Fix: "Something Went Wrong With the Trace Over Your Page Load" Error on Google Lighthouse

Howdy SEOs. I wanted to share a quick fix I’ve found to get rid of the “?” Score in Google Lighthouse Performance metrics — and more specifically, the error that reads: “Something went wrong with the trace over your page load. Please run Lighthouse again (NO_LCP).


I’ve noticed that this error especially tends to occur after recent pagespeed optimizations have been made to your site.

When checking my SEO blog’s Lighthouse stats this morning, I came across the above error. Note that my website was WORKING properly, and no errors in my html, etc. It was just inexplicably telling me I didn’t have a LCP(?).



How to Fix the “?” Score + Error in Lighthouse Metrics


After a bit of digging I found an answer to a similar question entitled, “How to fix “Lighthouse returned error: NO_FCP.”? Top answers recommended:

  1. Make sure no other Lighthouse tests are running/open
  2. Clearing your browser’s cookies + cached files
  3. Running the test again in incognito mode

And though my issue was with LCP instead of FCP, following these tips worked for me — and I was again able to see my performance scores:

My pagespeed is a work in progress, alright? 😉

Don’t stress — it’s literally that simple. And it usually happens after you’ve made some recent changes to the page.

Still getting a “?” Performance Score?


The other interesting point that I learned in this thread was that Google Lighthouse has recently instituted a “15 second timeout”. If your page doesn’t respond or any content within ~15 seconds, Lighthouse will give you an error somewhere within the performance metrics read out. I recommend visiting this resource from web.dev (Google also recommends this resource) for general education and tips for improving your page load times.

Hope this helped! Feel free to drop questions in the comments.
