How can I get this kind of search result ? I have search for digitalpoint on google.It gives more links with first result. How can I get that kind of result when people type the domain name with or without extension on the google? First result shows main links to the site.I saw most popular sites have this kind of search result when we search it's name on google. Could you please explain me how can I get that? Thank You.
Those are called Sitelinks, and you don't have any control over how to create them. You can check your Webmaster Tools account to see if any have been created for you. Even if there are, Google won't use them in search results until you have at least 4 of them. The only bit of "control" you have over Sitelinks is the ability to request that one of them be removed, but obviously that can only happen after Google has already created some for you.
Your site has to be deemed worthy by google by being in authority in your market niche. No one can request this to be done for their site.
