Well, sitemaps are just a bunch of links for the spiders after all, but there’s quite a bit of thinking that goes into before creating one. And that’s what we weren’t told about in all the thirdparty sitemap generators, but not anymore. Google’s sitemap generator tool thinks on it’s own - or so it looks like.
According to the official blog,
Our new open-source Google Sitemap Generator finds new and modified URLs based on your webserver’s traffic, its log files, or the files found on the server. By combining these methods, Google Sitemap Generator can be very fast in finding these URLs and calculating relevant metadata, thereby making your Sitemap files as effective as possible.
