I have a website, and I would like it when the name of this site was searched on Google, it would also show the internal pages below, as it happens on some institutional websites.
I was researching this, and I saw that you'll need to make changes to your sitemap in Rich Snippets. But, I have not found any information that helps me to change the current sitemap that I have.
This is the framework I currently have:
<url>
<loc>http://www.site.com.br</loc>
<lastmod>2018-04-09</lastmod>
<changefreq>weekly</changefreq>
<priority>1.0</priority>
</url>
What would I have to change?
