How to achieve Site Structure like this in Google. I just know it can be done via Sitemap submission i don`t know how ? Some people say use data highlighter, well i really don`t know how to use that. Some people say Google does it by itself when site gets trusted or old, but one of my friend did it on his domain in less than a week(don`t ask me to ask him, he won`t tell).Can someone guide properly with reasons ?
