wp_title( string $sep = '»', bool $display = true, string $seplocation = '' )

Display or retrieve page title for all areas of blog.

Description

By default, the page title will display the separator before the page title, so that the blog title will be before the page title. This is not good for title display, since the blog title shows up on most tabs and not what is important, which is the page that the user is looking at.

There are also SEO benefits to having the blog title after or to the ‘right’ of the page title. However, it is mostly common sense to have the blog title to the right with most browsers supporting tabs. You can achieve this by using the seplocation parameter and setting the value to ‘right’. This change was introduced around 2.5.0, in case backward compatibility of themes is important.

Parameters

$sep

(string) (Optional) default is '»'. How to separate the various items within the page title.

Default value: '»'

$display

(bool) (Optional) Whether to display or retrieve title.

Default value: true

$seplocation

(string) (Optional) Direction to display title, 'right'.

Default value: ''

Return

(string|null) String on retrieve, null when displaying.

Best practices

Plugins might use the wp_title filter to generate a value. While it is possible to construct a “title” by doing things such as concatenating with bloginfo (the Site Name), if you do not use the wp_title function in your theme, you will likely have errors or unexpected behavior.

Return Values

The function returns a concatenated string. It always queries the database for a default string; the value of the default string depends on the type of post or page:

Single post
the title of the post
Date-based archive
the date (e.g., “2006”, “2006 – January”)
Category
the name of the category
Author page
the public name of the user

The function then prepends or appends the sep string and returns the entire value.
