I am looking for a tool that will show me what the search engines are seeing. It is hard for me to know how to improve my search engine placements blindly. How do I know if robot text is working as I want it to? I have several pages in number one positions so I know it is not broken but I would like to analyze what is being spidered. I get searched 4 to 5 times a day by slurp and 2 to 3 by googlebot but they are not seeing all I have to offer.

Does anyone have any suggestions?

Try google alert. It will only show you google's latest search results for your site, not other SEs though. see here Google Alerts

Sorry about the above link, it should be GoogleAlert a different service.

Thanks for the tip.

But my concerns are different. This only addresses what was found. I am more interested in what was not found.

I am looking for a pet spider that will report to me just as the googlebot reports its finding to google.

Phpdig looks promising.
