Every blogger want a piece of site links from Google Search results for their blogs and websites. Google search results adds site links to blogs and websites if the search algorithm thinks that the link is useful. This process is automatic and is generated by Google search on its own. The site links were previously displayed just as a URL below the parent website or blog search result. Google on its official blog announced that they are releasing a change to the way the site links are being displayed with search results.
Sitelinks will now be full-size links with a URL and one line of snippet text—similar to regular results—making it even easier to find the section of the site you want. We’re also increasing the maximum number of sitelinks per query from eight to 12.
As the announcement said, the number of maximum sitelinks a site can have now being increased to 12 instead of just 8. Just look at the screenshot below for how the new site links look like.
As you can see, these site links do provide a whole lot of greater information about the useful links available on that particular search result. Google also plan to do some changes with its site link algorithm along with the way the site links are displayed. The site links wont be constant now for a particular blog or website and can vary depending on the search query. These changes are being rolled out globally and everyone must be able to see these changes soon.
