Hello, we’re sorry to hear that you’re facing issues with verifying your site on Google Search Console using Rank Math.
If you’ve followed all the steps and cleared your website’s cache but are still unable to verify your site, we recommend checking if the HTML meta tag from Rank Math has been added correctly to your website.
You can verify this by heading to Rank Math SEO → General Settings → Webmaster Tools from your WordPress dashboard and ensuring that the HTML meta tag has been added in the Google Search Console field.
If the meta tag is added correctly and you’re still facing issues, please ensure that there are no additional characters or spaces added before or after the meta tag. Sometimes, these extra characters can cause verification issues.
If the issue persists, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further. Thank you for bringing this to our attention.
