Hey , I was doing some research of seo specific for google for a pretty long time and decide to share some information with anyone who owns sites with half of million pages (or more) and hope if you can share something back. So what i figure out is that every page gets some rank only at point of indexing or recrawling , the most important part is that every page gets ranking depends on your DA and number of indexed pages. so i think the formula looks something like that ((DA/Number of indexed pages)*Content Update Date) * Number of backlinks to specific page, in other words the more DA(Domain Authority) you have and less pages you have the more chances that you inner pages will get higher in search results BUT you need to find golden middle between number of indexed pages and DA otherwise you might be loosen a lot of rankings if you have too many indexed pages or you could just waste your DA power if you have very few indexed pages. So basically when i am talking about huge sites I assume that no backlinks were built to inner pages. If anyone know (for sure) , for some testing purpose I need to figure out the fastest way to get deindexed all pages from google and let them index all again from begining.
