Whether you like it or not, readers will look at when a post was published and decided whether it is too old to be relevant.
That’s where adding a “last updated” date to your posts becomes important. You see it on tons of websites including The Wall Street Journal, the New York Times and Mom & Pop’s Record Store.
The reason is it helps calm the reader’s fears. They don’t want to waste their reading something that is not relevant or is outdated. Alerting them to the fact that the content is updated encourages them to read further with confidence.
It also gives them confidence that there’s someone actively working on the site.
In the tutorial below I show how to include the code to your functions.php file and have it appear right before the content. The process is automatic, so once you set it up you never have to worry about it again.
