The Duplicate Post plugin allows you to create quick duplicates of both Pages and Posts. This plugin is handy for creating quick alternative Pages for, say, if you want to create six service pages for six different cities in your region. The plugin duplicates not only the text, but all the tags, custom fields, title, and meta entries (if you are using an SEO plugin).

The plugin gives you two different ways to create a duplicate version of any Post or Page on your website. From the Edit posts or Edit pages navigation pages within the dashboard, you can click on the Duplicate link for the post or page you want to copy. You can also make a copy while you are in edit mode by clicking on "Copy to a new draft," which appears above the Move to Trash link.

Of course, once you have created a duplicate of your post using the plugin, you'll need to edit it so that it is not exactly the same as the original. The duplicate post gives you a good place to start if you are publishing a similar article, but you should rewrite some portion of the content so that the search engines will index both copies. If you have two identical articles on your site, the search engines will pick one to display and ignore the other completely. The Duplicate Post plugin is a useful tool to have if you frequently publish content that is similar to other content on your website, such as the localized versions of the same sort of information for different cities.
