Sitemap Suggestions

Now both Google and Yahoo have Sitemap features, Google Webmaster Central and in Yahoo Site Explorer. These two are very helpful for webmasters, but still they can add many new features like..

1. Option to include deleted and redirected pages.. so with this webmaster can inform about deleted pages which are still in the search index.

2. Option to view all indexed pages with page rank.. webmaster can use this instead of site command because site: is not returning correct results always..

3. New feature prefered domain is a good one in sitemap... but full url is already in the sitemap file... Why can't google take it from there?. anyway it is a nice option..

4. An announcement section for system maintenance, updates...data refreshes, alg changes.. etc

5. Number of pages crawled per day...

6. Default page.. Many html editors link to index.htm or index.html when you link to the top directory.. but when submit to other sites people submit only the domain name. This creates duplicate pages in google's index.. So like prefered domain, sitemap should have option to specify a prefered index page.

7. Average page loading time (while crawling the site). with this we can find out any crawling problem and fine tune our scripts and judge server performance.

8. if-modified-since, hearders, robots.txt, htaccess..etc are up to expectation or not ?

9. An internal ranking for each page (not page rank).. how much value given to each page.. like priority in sitemap...(0 to 1)

10. An overal rating of the site.. (depends on crawling efficiency, up time, quality of pages etc)
