If you are unfortunate enough to not have access to a tool or plugin to automatically ping your sitemaps on your site for you, you can still do this manually, and it’s pretty effective. A good example of this is a static site which doesn’t have the content update very often.  Simply prepare a simple page with these links:

• <a href=”http://www.google.com/webmasters/sitemaps/ping?sitemap=http://your-domain.com/sitemap-url”>Google</a>
• <a href=”http://search.yahooapis.com/SiteExplorerService/V1/updateNotification?appid=YahooDemo&amp;url=http://your-domain.com/sitemap-url”>Yahoo</a>
• <a href=”http://webmaster.live.com/webmaster/ping.aspx?siteMap=http://your-domain.com/sitemap-url”>MSN</a>
• <a href=”http://submissions.ask.com/ping?sitemap=http://your-domain.com/sitemap-url”>AsK</a>
• <a href=”http://api.moreover.com/ping?u=http://your-domain.com/sitemap-url”>Moreover</a>

Step 1: edit each link code with the url to your site’s sitemap.

Step 2: then copy the code for each line to a new page/post or html document.

Step 3: create the rest of the page.

Step 4: publish it. Each time you need to ping these sites, open this page and click on each link. It only takes a few seconds, and is ideally done as part of a checklist of things to do.
