Google Sitemap HTTP Ping
This post talks about how to submit site map of your blog/site automatically to Google/Yahoo on posting the content every time. The normal process is to submit your sitemap in Google Webmaster tools, but the shortcoming is that Google picks the site maps on regular interval once in a day or so, but If you are updating content several times within a day then you might need to submit/update your sitemaps every time.
The process of sending sitemap updates to Google / Yahoo / other search engines is called HTTP Ping for sitemaps.
For Google below is the process of sitemap HTTP ping.
Build the following url say if
your website name is : http://www.mysite.com and
your sitemap url is http://www.mysite.com/sitemap.xml then the following is the url you need to build for sitemap
Since we are sending the GET request we need to do a URLEncode of the your sitemap url.
This can be achieved through following method UrlEncode in PHP and Encode in Java or you can use free encoders available online to encode the sitemp url one time.
When I did encode of the above http://www.mysite.com/sitemap.xml this is what I got
So our final url is
send the request using wget or curl or any class of your choice.
If you get back HTTP 200 response then its a success else try it again. Google says you can send updates eevrytime you update/add content to your site and it can be upto every hour. So this will help you boost the updated nature of your content in Google search engine.
