Thanks for sharing.
Yes, I already figured out that it seems that there are two AdSense Auto ad code snippets on the website. However, if I disable Google Site Kit AdSense Auto Code replacement, then I do not have any AdSense Code in my WebSite.
Site Kit only inserts the Auto ads snippet on one occasion on a users site. From checking the details you kindly provided I do see this warning when checking your site, and I noticed what looks like non Site Kit placed ads related snippets.
Can you check if the same console error appears after following the steps below, which will help determine the cause?
- Login to your site from a Chrome browser incognito window
- Install and activate the Health Check & Troubleshooting plugin.
- Navigate to “Plugins > Health Check & Troubleshooting > Troubleshoot”.
- From the same screen click on the “Available Plugins” tab at the top right and then click on the “Enable” option next to “Site Kit by Google”
- Check for the console error once more
Let me know how you get on with the above, or ask if you have any questions.
However, since I know that it doesn’t impact the ads being served, it is still being complained by lighthouse and my beforehand 100% is now down to 83%.
When you add servers to your website, including ads or Google services there are additional http requests made. Such trade offs are not uncommon although you can use the insights and suggestions from PageSpeed insights for any performance improvements. You can also consider AMP for your website to maintain a high performance.
