What is a Permalink? Trackback? Post slug? Ping?

I was in a fantastic luncheon today with some very intelligent marketers from all over Indianapolis. Every 4 to 6 weeks we meet to discuss a new (or popular) business or marketing book. It’s a great opportunity to get out of the office and out of the details and get back to some ‘big picture’ thinking. Some of the folks are print and media, others are Internet savvy. One comment I heard today confused some of the blogging jargon. I may incorporate some of this into the E-metrics guide I’m writing, but it’s worth the blog entry, anyways:

What’s a Permalink?

A permalink is a ‘permanent link’ to your post. This is a feature that may require enabling on your blog, it allows a user to specifically point to a single, textual, web address for each entry of content. For instance, the E-metrics article I mentioned above has a permalink of:


What’s a Trackback?


Trackbacks are powerful but are getting abused more and more by spammers nowadays. Here’s how they work… A blogger reads your post and write about you. When they publish, their blog notifies your blog by submitting the information to a trackback address (hidden in the page’s code).

That allows you to see that someone has been writing about your post online. It’s an amazing tool because it’s non-intrusive and it’s a means of informing someone that you’ve written about or are passing along your information through their blog. Always use Trackbacks when you discuss someone’s post or blog. It’s courteous. If you’re going to write about them, you should at least give them an opportunity to respond.

Of course, this is a gold mine for spammers. They utilize software that actually pings your site with the URL they want you to visit and they didn’t actually write about you at all. For this reason, we’ve gone ahead and disabled them in our WordPress settings.

What’s a Post slug?

A post slug is a textual reference to a post. Using the above example, the post slug is blogging-e-metrics. The post slug of this post is ‘blog-jargon’. If you have numbers at the end of your post, you need to enabled Permalinks on your blog. That allows textual, hierarchical URLs to be built for each post and page in your site. This can be advantageous for search engines… using keywords in your post slugs can help! You need not worry about writing these yourselves every time, though… your blogging software should do it for you. Sometimes I like to shorten them up a little with a long title like tonight’s post!

What’s a Ping?

(Short for Pingback) Once used to simply test communications between two computers on a network, now ‘pings’ have evolved for blogging. If you have pings enabled in your blog, your blog will automatically ping the recipient service to let them know when you’ve published to your blog. That allows the search engine to then ‘crawl’ your site for content and place you accordingly. I ping 5 services out there… they may be repetitive but I’m okay with that:

  • http://rpc.technorati.com/rpc/ping
  • http://rpc.pingomatic.com/
  • http://api.feedster.com/ping
  • http://rpc.newsgator.com/
  • http://xping.pubsub.com/ping

These services, in turn, then track and place my content within their search engines as well as submit them to others. Make sure you have pings enabled in your site!
