If you use WordPress:
- If you want to add the text/link directly into your template files (header.php, footer.php, sidebar.php, etc), here is the code you need to use:
<?php if(is_home() && !is_paged()): ?>THE TEXT/LINK OF THE OFFER<?php endif; ?>
- If you want to put the text/link in a specific widget, you can use the Widget Logic plugin, and insert the following code in the "Widget Logic" field of the widget:
is_home() && !is_paged()
If you are using another CMS, we advise you to check their documentation and any related forums for the correct code or plugin.
