A sitemap for your website is possibly one of the most important things you can add to your site to help with Search Engine Optimization, and getting the maximum number of pages indexed to improve search engine traffic.
If you use Serendipity, Wordpress, Joomla, or any of the popular CMS systems then you probably know that you can install a plugin that creates sitemaps in at least one format that the search engines spiders will read.
The problem is that most only submit your sitemap to Google, which is great, and of course they have the largest market share, but there are other search engines, and some of them will often provide different traffic that you may never get from Google.
Here's why; Yahoo, MSN Live, and Ask.com all index a site differently, for example Yahoo tend to like pages that are quite topical, on this blog I get more traffic about Italian phrases from Yahoo than I ever get from Google, yet hardly ever get SEO traffic from Yahoo which tends to be one of my biggest keywords from Google.
It is worthwhile getting your site indexed by the smaller search engines, I'd even go so far as to say that some of that traffic might convert better, so without further ado, here are the urls you need to use to submit your sitemap to Google, Yahoo, MSN Live, and Ask.com
http://www.google.com/webmasters/tools/ping?sitemap=
http://search.yahooapis.com/SiteExplorerService/V1/ping?sitemap=
http://webmaster.live.com/ping.aspx?siteMap=
http://submissions.ask.com/ping?sitemap=
To use any of these URLs, simply add the full URL of your sitemap file after the = sign.
