I am working on SEO and link building for the site designdirectuk.com. I want Google sitelinks for this site, but I am not getting the same. Please Help!
You don't have direct control - it's automatically generated by Google as putradi said. But if you have a high enough PageRank and you put links at the bottom of your site on every page, those links should become your sitelinks.
you need good internal linking structure to be able to develop sitelinks as stated above with bottom of the page links
