The Difference between Pingback and Trackback
Many bloggers are often confusing pingbacks and trackbacks, but what is the difference between pingbacks and trackbacks? here I list some features of them.
Pingback and trackback have different protocol mechanism. Pingback works on XML-RPC of notification medium. but the trackback uses HTTP POST.
If your site has open the pingback function, the pingback should find the URIs in your post and ping them automatically, But the trackback destination needs to be filled with a proper link address and notify it manually.
The result of pingbacks, similar as: "Article title->Blog name"+"[...] Blog name + Blog Description+...+ Article title [...]"
The result of trackback: Only similar as: "Blog name"+"article excerpt".
If you update your article, pingback will automatically notify the URIs in your post, but trackback should be excuted manually if you want to.
Super example: If you have written a new blog, you may need to send a "pingback" to google to update it. while if your blog has some content related to others article, you may need to seed a "trackback" to other's blog manually.
