I'm starting a project for which I have all the content and data. It's going to be a fresh site with a fresh domain. I've heard about the search engine sandboxing so I would like to make sure I do all this right and need your advice. I will have about 2 million pages total. 1. How many pages should I have in the beginning before I generate sitemap and submit the site to search engines? 2. What's the maximum number of pages I can load per day after initial launch? Any other advise is also greatly appreciated.
