The Google Sitemaps tool added some new features this week, I reported them over at the SEW blog about two days ago. I wrote that Google Sitemaps Adds Top Keyword Positions, Top Mobile Queries and CSV Downloads;
(1) Your average position by your top search queries. This is basically a site ranking report for the your top keywords, the keywords people search to find you on.
(2) If you have mobile enabled site, you will also now see your top search queries on mobile devices.
(3) You can now download "details, stats, and errors" to a SV file that you can then do what you like with it.
Now that this has settled in some, the forums have had their chance to speak their mind on the features.
WebmasterWorld has a thread on the topic and has several responses from the Sitemaps users.
