A favicon (short for favourites icon), also known as a website icon, shortcut icon, URL icon, or bookmark icon is a 16×16, 32×32, 64×64 pixel square icon displayed by most web browsers next to URL.
For example, Yvonne writes an interesting article on her Web log. Kathleen reads Yvonne’s article and comments about it, linking back to Yvonne’s original post. Using pingback, Kathleen’s software can automatically notify Yvonne that her post has been linked to, and Yvonne’s software can then include this information on her site.
There are three significant differences between pingbacks and trackbacks, though.
The best way to think about pingbacks is as remote comments:
The pingback is generally displayed on Person A’s blog as simply a link to Person B’s post. In this way, all editorial control over posts rests exclusively with the individual authors (unlike the trackback excerpt, which can be edited by the trackback recipient). The automatic verification process introduces a level of authenticity, making it harder to fake a pingback.
Some feel that trackbacks are superior because readers of Person A’s blog can at least see some of what Person B has to say, and then decide if they want to read more (and therefore click over to Person B’s blog). Others feel that pingbacks are superior because they create a verifiable connection between posts.
A slug is a few words that describe a post or a page.

The slug for that post is “
