Did you know that there’s an easy way to keep that updated automatically?

On any server that supports PHP, so if you simply drop this code wherever you want, (for example, into your WordPress themes footer.php file) then you’ll automatically have a current copyright date on every page.

©
<?php
echo date("Y");
?>

The first line is the © copyright symbol, and what’s inside the brackets generates the date. You can of course add anything to this that you wish, like All Rights Reserved, your company name, your domain, or even links to this site.

What if your server doesn’t support PHP, or for some reason this doesn’t work?

Here’s a pretty cool tool that gives you even more flexibility, and although it uses JavaScript, it’s still better than an outdated page. It’s better for your users as well as the search engines to see that you’re keeping your website up to date.
