Things change all the time. Associated Content installed their newest feature yesterday. It makes my article about using the publish template a little out of date, but that’s OK because it’s progress.
On page three of AC’s publishing template there is now an area labeled “Terms that describe the topic of your content. (5 max, separate by commas).” Here’s the official pop-up help:
Enter single words or phrases that describe and define your content, specifically and in general. These tags are used to link this submission to related content and vice versa.Example: An article on the 2008 Presidential Election could have these search tags: politics, presidential election, election 2008, Barak Obama, John McCain
So what is it really? Tagging. Which is cool and very helpful to the search engines.
