WPSSO Core uses the WordPress
get_the_title() functions to determine the title of most webpages. These WordPress functions are used by theme templates and plugins to retrieve the title of the current webpage, or any page / post ID. WordPress also provides filters for these functions — a way for plugin authors to modify the title for various purposes. These filters are often used by SEO plugins, for example, to modify / standardize the webpage titles. See http://codex.wordpress.org/Plugin_API/Filter_Reference/wp_title for more information.
If your Open Graph and webpage titles (shown in the web browser’s title bar and tabs, for example) do not show the correct information — perhaps always showing your website name, and not the current post / page title — then perhaps a plugin or theme has “hooked” into the
wp_title() filter to manipulate its output. By default, the
wp_title() function should return the post / page title, which changes from one post / page to another.
