I started a couple of websites and linked them with webmaster tools. For Site A website I kept on resubmitting the sitemap (2-3 times a day) and for the Site B I just submitted it just once. All the pages for Site A got indexed in a week while only 2 Pages for Site B got indexed. Then I tried the same with Site B and all the pages got indexed in about 7 Days. (I had about 10 pages on each site) I did some social bookmarking and made about 10 PR4+ backlinks for both. Just thought I would share!!
