How does it make changes to your content to internet surfer?
Blog pinging means that you are calling google bots to crawl your blog content and index in
their database. so that when somebody search for the content that your blog has, your blog comes on google serps( search result pages). If you have updated your blog and yet google crawler has not crawled your page then by using ping service you are inviting them to crawl your blog's latest post.

If you have pinged your blog then you have submitted your blog for google crawling. Your data of blog is submitted to google. If some one searched related to your submitted item then google will show your post in result as well.
