Netestat dar ar trebui sa mearga pe taguri:

<!-- Tag based content START -->
<p>
<?php if ( has_tag('WordPress') ): ?>
<!-- This code will be displayed if the post has a tag named 'WordPress' -->
<!-- Tag 'WordPress' code starts here -->
<!-- INSERT advertising code for posts with tag 'WordPress' here -->
<!-- Tag 'WordPress' code ends here -->

<?php elseif ( has_tag(array('How-To', 'Monetize')) ): ?>
<!-- This code will be displayed if the post has at least one tag defined in the array -->
<!-- Tag 'How-To' or 'Monetize' code starts here -->
<!-- INSERT advertising for several tags here -->
<!-- Tag 'How-To' or 'Monetize' code ends here -->

<?php else: ?>
<!-- This code will be displayed if the conditions above don't hit (you can also remove the else) -->
<!-- Code for all other tags code starts here -->
<!-- INSERT generic advertising code or other content here -->
<!-- Code for all other tags code ends here -->

<?php endif; ?>
