I have seen that for some top keywords, google shows more than regular links for some sites which appears at the top in results and called as site links. for an example when we search for keywords- "seo forums" seochat.com appears at the top but google also show some more links for the same site below main page for it like- http://www.google.com/search?sourceid=navclient&ie=UTF-8&rls=GGLJ,GGLJ:2006-39,GGLJ:en&q=seo+forums I just want to know that can we do anything or there is any method so that we can also get these site links fo our site form google for our targeted keywords.
A proper and effective internal linking structure is the best method, which should already naturally exist within your website.
