I learned something new about trackbacks, pingbacks, and backlinks, but I am still quite puzzled by these.
Trackback can be faked, and encourages spamming.
Pingbacks support auto-discovery where the software automatically finds out the links in a post, and automatically tries to pingback those URLs, while trackbacks must be done manually by entering the trackback URL that the trackback should be sent to, and do not send any content as trackback does an excerpt to original post.
One notable blogging service that does not support trackback is Blogger. Instead, Blogger provides "backlinks", which allow users to employ Google's search infrastructure to show links between blog entries. Which may mean a lot of delay to find out the links if other website are not indexed quickly by Google search engine, there will not be "immediate effect", it will be "long term" to get the backlinks to show up into you comments area.
Is my understanding of trackback, pingback, and backlink right?
