If you don’t see the website that you want to optimise within the Available section of the Websites tab two things could be the case.
You don’t have your website connected to your Webmaster Tools account. If this is the case, please go to the ‘How do I make my website available’ chapter of this document.
If you are sure that the site is connected to the Webmaster Tools, click on the ‘Re-fetch Available Websites’ button within the Available section (grey button on the right side of the screen). A popup window will appear. Click on the ‘Re-fetch my available websites’ below the message. This way Polkadot Tiger will inspect the Wordpress sites connected to your Google account.
