@munabaly,
The links shown below the search results are the so-called Sitelinks and they are automatically generated by Google based on your site structure. It’s not based on our plugin’s settings. The Yoast plugin automatically adds all the necessary Schema needed to generate Sitelinks. So you won’t need to change anything from the plugin.
You could signal to Google which links you want to appear by using the following actions:
1. Provide a clear structure for your website, using relevant internal links and anchor text that’s informative, compact and avoids repetition. These guides explain more: Site Structure of a Growing Blog, Site Structure for SEO, and Clean the Site Structure
2. Allow Google to crawl and index important pages within your site. Use Fetch as Googlebot to check that they can be rendered properly.
3. Be sure to then resubmit your sitemap to Google as it will encourage Google to reindex your site and update its index. This guide explains more — Submit Sitemap to Google
4. You may also wish to contact Google for more information on how they decide which links appear. You can contact Google by making a post on their forums — https://productforums.google.com/forum/?rd=1#!forum/webmasters.
Thank you.
