log side reporting tool

[hugo_guzman]

I'm looking for a high end reporting tool. I need something that will allow for the following:

1)Keyword reporting. What keywords are being searched for and on what search engine(s). How much traffic per keyword(s), etc...

2)SERP reporting. What ranking do specific search terms have (data must be reported for Google, Yahoo, & MSN at the very least). The key here is that this data must be logged so that I can refer back to it at a later date i.e. what position was I in on March 13th of this year...

3)This must be software application that gathers the data from server logs,etc... It cannot be a third-party tracking counter (I cannot insert a snippet of code in web pages).

I have recently been retained by a large corporate entity, and I am working on a report that will justify sweeping changes to a site's internal linking structure (anchor text changes, etc...) and general seo initiatives.

They were working with web position gold, but I am not sure that this is the best tool for the job at hand. Also, money is not really an issue here.

I would appreciate the help.

There have been a few requests for keyword-analysis tools recently. A question: does a search for "blue widgets" count as a hit for 'blue' and for 'widgets' or just one for 'widgets' or ...?
(ie. do you have to pre-specify what your key words/phrases are for the analysis?)

If you had a sample of the input/output that might make things more clear.
