Sitelinks
Sitelinks are the links shown below some sites in search results and are meant to help users navigate to your site. Google analyzes 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 and when it does find something suitable then it creates a sitelink. This is what a sitelinks look like

There need to be atleast three sitelinks created by Google for a particular site for the sitelinks to be displayed. The unfortunate part is that we cannot tell Google to create sitelinks according to our choice, it does so on its own. However once Google does create a sitelink and if you dont want that particular link to be displayed then you can block it. Simply go into webmaster tools, there go to the sitelinks option and block a particular sitelink. Once blocked within a few days Google stops showing the sitelink and the sitelink remains blocked for a 90 day period. If you want that sitelink to be blocked for more time then all you need to do is just go to the sitelink page on webmaster tools. Each time you do so the sitelinks will be blocked for an additional 90 days. You can unblock a sitelink whenever you wish too
So how do sitelinks help an SEO campaign? Many a times it might happen that Google might create sitelinks of pages that you think people might not visit frequently or more importantly you feel that there are many more important pages that deserve a sitelink. Then if you block a sitelink, Google automatically will create some more relevant sitelinks. Having irrelevant sitelinks might deter users from visiting your site and that is definitely not something that you want to happen.
