As you can see in the attached image, the meta name=“viewport” tag has been inserted, but PageSpeed Insights still throws an error no matter how many times I try.
It looks like you’re facing an issue with the <meta name="viewport"> tag not working as expected. The viewport meta tag is crucial for ensuring proper responsiveness and display on different devices. Here are a few steps you can take to troubleshoot and resolve the issue:
Verify the placement: Make sure the <meta name="viewport"> tag is placed within the <head> section of your HTML code. It should be placed before any other CSS or JavaScript files.
Check for conflicting code: Ensure that there are no conflicting CSS or JavaScript codes that might be overriding or interfering with the viewport settings. Look for any other viewport-related tags or CSS properties that might be conflicting.
Check the syntax: Double-check the syntax of the viewport tag to ensure it is correct. It should resemble the following:
Pay attention to the placement of quotes, commas, and the values of the content attribute.
Clear cache: If you have previously tested the <meta name="viewport"> tag and it didn’t seem to work, try clearing your browser cache. Sometimes, cached versions of your website might not reflect the recent changes you made.
I have faced the same issue. It was caused by another app I installed for blocking frauds and visitors from specific countries. After uninstalling it, all my pagespeed metrics became green as the meta tag was detected at last.
