Tarik: We used sitemaps 15 days ago. We submited the sitemap.2 days later deep craw started. After submiting, our traffic from google dropped from 2000 visitor to 200-300 visitors. There were 19000 pages in the index before but now we have 48500 pages in the index traffic is near 400 visitors now. Before submiting we changed our link structure. All pages with rank disappeared. This is normal but how long will we wait? Will there be an increase in the traffic? As our pages in the index increase will our
page rank increase?

Randy: Sitemap is becoming a big problem. Google's sitemap forum is being overrun with help requests, including my own. The above is a case in point. Here, the author made a critical SEO mistake by taking down all his pages with rank. His traffic won't return until he builds up rank on the new pages.
