The way title tags display in WordPress is Blog Title >> Post Title. But you may have noticed that some sites display like Post Title >> Blog Title.
Optimal Title is a WordPress plugin that mirrors the function of
wp_title() exactly, but moves the position of the ‘separator’ to after the title rather than before. This allows you to have your blog name tacked on to the end of the page title instead of having it appear first.
Having your page information appear before your blog name in the title is advantageous because it provides more meaningful search engine results and browser bookmark names. The text that appears between your <title> tags is used to generate both of these things, and will often be truncated when viewed. Because of this, it is more effective to have words directly relating to the content of your page appear before common markers. Not only will the titles be more meaningful, but the they will also be more scannable when being viewed in a list.
