In the last few months, Google has made a lot of changes to its Search Results Page. Recently, it was noticed that Google is testing expandable sitelinks for its mobile search results and you can now see an expanded category of the website and subsections of the important pages within the link.
Google Sitelinks are the navigational links that you see in Google Search Results under the website description. These are the links to the important pages of the website that help you find what you’re looking for.
This is what the modified mobile search results page looks like:
The new design allows the users to directly go to the website page that they want to visit, without navigating through the whole website. This saves a lot of time, as well as, makes it very convenient for users to find the most relevant page to their search.
This is one more step by Google to make the mobile user experience faster and simpler.
