See Exactly Where Your Website Appears In Search Engines
Once you submit your XML Sitemap to Google you get to see exactly where your website appears for various search terms as well as how many users are clicking your website for that specific term in Google's search engine result page.
Search information is graphed over time and you can even compare your keyword performance by country and in Google's specific search engines such as image search and video search. The average position of each search term in Google's result page is shown next to each keyword as well.
Yahoo and Bing also provide similar feedback including who links to your website, and any problems they experience when adding your website to the search index.
