How and when google is adding new domain names into it's SERPS?! It's adding all them at once?! like every week ? or it's adding the new domain names, one by one , as it's finding it... Also how is the first crawl ?! is it an in deep crawl? or it's a normal crawl?!
I believe they add in new domain names if: 1) There is a link to this new domain on an existing page (crawled by the bots) OR 2) The owner of the new domain create and submit the Google sitemap.
if you can get a link from a trusted high pr site you will be in the index within a couple days...sometimes way less than that...
