I have run a link checker on my site and it came up with this link:

<link rel='dns-prefetch' href='//fonts.googleapis.com' />

I confirm this URL is not valid. How do I isolate why did bad link is in the site? Is it an issue with the WordPress core? The theme? I tried looking in the theme code and I can't find it.

  • What "link checker" were you using? The reported "error" is really a fault /limitation of the link checker. Note the rel="dns-prefetch" attribute.

If you are trying to view the site fonts.googleapis.com in a browser, you might think it is not a valid URL, but it is actually used to load Google fonts in the background of your WordPress site. This might be via a theme or a style sheet.
