Oddly I was just thinking of this tonight and searched for this current topic.
1. I have an oddly named site map file and was getting ready to relocate it. I was wondering if anyone is aware of a "standard" name for the file. Sitemap.htm could easily be confused with a SE submitted sitemap file.
2. I do a combination sitemap/ask-us/google custom search page. If they can't find, or are to lazy to search the site map for it, they can search. If they STILL can't find their answer they can form e-mail us.
3. Where should the site map be linked from for best effect? Every page? Every 1st level category page? 1st + 2nd level? Home page only? If you link it from almost every page, to benefit users the most, it gets a lot of PR, but almost never winds up on the SEs because it is so general in nature and mostly a bunch of links.
4. IF you include a Google Adsense search field on every page does it leak a lot of PR back to G? Instead should you have a "search" link from each page to a single, central, on-domain search page which is the only single place the Google Search field is located?
