The project is being held in a developer sandbox for testing. The aim of the development is to increase “”size, indexing speed, accuracy, comprehensiveness and other dimensions.””
Blocking my page in robots.txt will prevent indexing.. This is just not true, your robots.txt is a tool used to prevent crawling… not indexing. While blocking a page in robots.txt will prevent well behaved spiders from crawling these pages, it will not prevent indexing, remove a page from the index, nor block the flow of PageRank to the page.
