Insert Google Analytics without editing your theme

I like to use Google Analytics, but the boring stuff is that when you switch themes, you’ll have to re-insert the code in the new theme. To avoid it, let’s use the power of WordPress hook to insert our analytics code without editing theme files.

Just insert the following code into your functions.php file, and you’re done. Don’t forget to paste your Google Analytics code on line 5.

<?php
add_action('wp_footer', 'ga');

function ga() { ?>
    // Paste your Google Analytics code here
<?php } ?>

Have you checked out the new Headway theme for WordPress? It is pretty cool. You can read a review here.
