How can I achieve this?

Hi,

Just wondering if anyone could tell me how to achieve column links on google?...

These are "SiteLinks". Google displays them for your site,
when it considers your site as an "authority" for a particular keyword.

From the Google Webmaster Tools :

Sitelinks are additional links Google sometimes generates from site contents in order to help users navigate your site. Google generates these sitelinks periodically from your site's contents.

Because we generate sitelinks dynamically, this list can change from time to time.

Sitelinks are completely automated, and we show them only if we think they'll be useful to the user. If your site's structure doesn't allow our algorithms to find good sitelinks, or we don't think that the sitelinks are relevant to the user's query, we won't show them.

Maintain a clean and clear navigation structure and keep building links to your site. Check the Google Webmaster Tools to see your status for these site links.
