6. Supplemental index
   • Why and How?
     
     Assuming all your urls are unique and original, how many of your urls will be in google's main index? Let's say you create a brand new website last week, and it has 1,000 unique urls, all with great and original content, and the website's structure is perfect done by the best SEO company in the world, how many urls out of your 1,000 urls will be in google's main index?
     
     Well, if you are lucky enough to be indexed by google, the maximum urls in google's main index is 1, the home page itself, the rest 999 urls will be in supplemental database.
     
     Why? Think yourself as google's owner, will you put all the 1,000 urls in your main index from a site that is a week old?
     
     Here is the formula that I discover to determine how many urls to be in google's main index:
     
     Primary urls = 3.32 * 10 ^ (PR - 1)
     
     So, if you have PR 4, your maximum urls in the main index is 3,320. This calculation assumes you don't waste your PR: that is, if you try to distribute PR 4 evenly to 6,640 urls, all 6,640 will be in supplmental, except perhaps the home page...Of course, in reality, google will adjust its calculation and redistribute the energy so you may have 1,000 urls in the main index.
     
     So, if you have PR 4, pick the best 3,320 urls and distribute the energy to them for fully index, if you try to distribute to 4,000 urls, then you will have this many in the primary index:
     
     3,320 - ( 4,000 - 3,320 ) * 2 = 1,960
     
     The constant value of 3.32 may be slightly different...
     
     PR 0: maximum primary urls indexed: 1
     PR 1: maximum primary urls indexed: 3
     PR 2: maximum primary urls indexed: 33
     PR 3: maximum primary urls indexed: 332
     PR 4: maximum primary urls indexed: 3,320
     PR 5: maximum primary urls indexed: 33,200
     PR 6: maximum primary urls indexed: 332,000
     PR ≥ 7: all in primary index ...
     
     Again, the assumption is all your urls are original and unique and with great value.
     
     
   • How to get out of supplemental index?
     
     Obviously, improve your page rank!
     
     
7. Submitting sitemap or not - does google really trust user submitted sitemaps?
   
   It depends on your PR. If your PR is 7 or higher, yes, google MAY trust you.
   
   But if your PR is 4 or less, don't bother to submit any sitemap! At best, it will have zero effect on your site, at worst, google will use them against you!
   
   Instead, design your urls so that they can be reached from home. It is a sort of tree structure, from root to leaf, without broken path...
