Google has implemented a cutting edge method of crawling web site for its search engine index. This unprecedented method of indexing web pages is known as Google Sitemaps, and it is quickly growing in popularity among webmasters and SEO agents and managers due to its ability to get entire web site indexed quickly and to pick up errors in the links coming into and out of these web site.
Google Sitemaps consists of placing the URLs of your pages along with important information regarding how Google should index them into an XML document. This information is then read by the Google Spider and the pages are normally indexed quite quickly assuming that they are coherent to Google’s standards for indexing pages (and also assuming that the sitemaps conform to Googles Sitemap Criteria which will be explained a little later) google index download.
There are two primary types of Google Sitemaps. The first is a list of pages in a website and the second is a list of sitemaps in the website. Google has limited the number of URLs in its sitemaps to fifty thousand URLs. This may sound like a lot, but for some of the more intricate web site, fifty thousand URLs may not even make a dent in what they want indexed.
This led to the advent of the Google Sitemap index file which can index up to one thousand sitemaps. If you do the math, this means that you could have one thousand sitemaps with up to fifty thousand URLs in each sitemap which allows for fifty million URLs to be placed in your Google Sitemap scheme. But wait, there’s more. Who ever said that you can’t have an index of indexes? You could actually make an index of a thousand index files which are all indexes of a thousand index files. Basically, there is no limit to the number of URLs that you can hold in your Google sitemaps.
