Many people dont have a clue on what sitelinks actually are. Frankly, i was also not aware about the term. And i was foxed to see links below some sites. Then I started investigating it.
First thing, I found was that these links below a site listings on google search pages are called "Sitelinks".
Google explains it like this "The links shown below some sites in our search results, called sitelinks, are meant to help users navigate your site. Our systems analyze the link structure of your site to find shortcuts that will save users time and allow them to quickly find the information they're looking for."
Google also explains that sitelinks are completely automated. It means that it may very well be possible that Google's algorithm may churn out inaccurate or wrong sitelinks. Though a webmaster cannot do anything to correct the sitelinks, what webmaster can do best is to Block it.
Since, Google has not revealed the algorithm for sitelinks just like their other algorithms, webmaster and SEO cannot do nothing much to directly influence the sitelinks. This I personally feel to be a good thing as it gives rogue SEOs less options to manipulate and ruin another potentially good thing for site visitors.
Over the next week, i will research on the subject on how to get these sitelinks. I will surely keep you all updated.
I'm curious. I didn't even realize these existed. I'll look for your update.
