WordPress is really an excellent blogging software which anyone can just plug and play. It is easy to install and use and plenty of useful features to aid in anyone blogging needs. One of the great feature is its dynamic sidebar that allows you to add plenty of widgets with just a few clicks in the Admin page. Great as it is, there is an limitation: It is static throughout the blog. What appears on the front page will also appear on every single page. There is no way to configure which widget to appear on which page. If you are happy with a static sidebar, then this shouldn’t be a problem with you. However, if you want to show a specific ad on a specific post, then this will going to be a limitation to you.

However, when a specific page/post is loaded, the widget that you specified will also appear on the sidebar.
