SEO Failed Tests

Hello,

Thank you for contacting Rank Math, and sorry for the inconvenience caused.

1. No keywords found in page title

You will need to add the keyword in your Page Title.
Go to specific page > Add Title and in the page
go to SEO Settings > Edit snippet > Check if you have the keyword in the meta title.

2. Permalinks
We do not recommend changing permalinks for an already established website.
However, if you still want to do it, you may refer to this post https://wpbuffs.com/wordpress-permalinks/

3. WWW and non-WWW
Your site does not seem to have proper redirections. You will need to add the rewrite rules for this one.
If you want to redirect from www to non-www. You can add the below code in the .htaccess file

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.yourdomain.com [NC]
RewriteRule ^(.*)$ http://yourdomain.com/$1 [L,R=301]

Replace yourdomain.com with your actual domain name.

4. Opengraph meta

The OpenGraph tags are automatically generated from the meta tags. In order for me to be able to advise further, kindly share with me a related URL to the affected page using a sensitive data section so that I may be able to advise further.
Alternatively, you can fix this problem by adding a default OpenGraph image via WP Dashboard > Rank Math > Titles & Meta > Global Meta and assign a default OG thumbnail.

This will be used as the default OG image but you can head over to your homepage and assign featured images that will be used for the homepage.

I hope this helps. Looking forward to helping you. Thank you.
