My experience has shown that announcement posts are almost always more effective when they are combined with a sticky notification visitors won’t miss easily. Adding a notification bar with your announcement message and link to WordPress is not that difficult. WP-TopBar is a quality plugin that lets you display a message bar at the top or bottom of your website.
Your TopBar will be highly customizable and can be shown at the top or bottom of your website. Users can change the color, text, image, and link in their bar. Delay, display, starting, and ending time are changeable too. If you know your CSS, changing the position of this bar won’t be that much of an issue. But even if you are a newbie, margin and padding settings can be changed from the settings page.
WP-TopBar is social media friendly and highly customizable. You can even debug this plugin from the settings page. This is a pretty neat tool to use if you need to add a notification bar to the top or bottom of your website.
