Check Pages Indexed
This tool queries the three major search engines (Google, Yahoo and MSN) for the number of pages from a website present in their search database.
If the number of pages indexed differs greatly from the number within the search engines, then search engine spiders may be encountering problems spidering the site, or there might be a lack of incoming links (if the number if to low); alternatively, there may be problems associated with duplicate content such as that created by some dynamic websites (if the number is too high).
