“noindex” tag is added on HTTP Response

Hello,

We’ve had a similar issue before regarding the Buy Now WooCommerce plugin. The Buy Now Button for WooCommerce plugin is setting the product pages as the cart or checkout pages and that’s why our plugin is setting them as Noindex.

Can you please try adding this filter to your website and see if it helps?

add_filter( 'rank_math/frontend/robots', function( $robots ) {
    if( is_cart() || is_checkout() ) {
        $robots['index'] = 'index';
    }
    return $robots;
});

You can add the filter via a plugin or through the rankmath.php file. You can also add it to your functions.php file but it may replace the code whenever the theme is updated. So the first two options would be the best practice. You can learn more about this here:

If that didn’t work, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Hello,

In this case, would you kindly share your WordPress Logins as stated in my previous reply?

We would also need to check if the code was added properly as well.

We really look forward to hearing back from you. Thank you.
