I saw some of site just opened newly but their have page rank. But my question if the site brand new, how they got page rank and when google give any site pagerank. Someone have knowledge about this please share me.
That depends.
If website have opened and google updated page rank, then it can get good rank.
Like website is opened a week ago and google update the page rank, then website will get good rank if it is a healthy site.
