[WordPress] How to display the page title and how it should be displayed

This is a story about how to display page titles and how they should be displayed.

First, I would like to list some ways to display page titles in WordPress.

How to display [blog name]

<title><?php bloginfo('name'); ?></title>

'name' is the 'site title' set in 'Settings > General' on the administration screen.

How to display [Page title]

<title><?php wp_title(''); ?></title>

To display the page title in WordPress, a template tag called wp_title is used, which is a very flexible and convenient tag.

use box sizing property for align the size of the form items

• When viewing an individual page or article, display its title
• Display date when viewing archive page
• Display category when viewing category page
• Show tags when viewing tag page
• Display the author when viewing the author page

It will display each one like this.

How to display [Blog name | Page title]

To display the combination of blog name and page title as [Blog name | Page title], write as follows.

<title><?php bloginfo('name'); ?><?php wp_title(' | '); ?></title>

Or you can write it as follows.

<title><?php bloginfo('name'); ?><?php wp_title(' | ',true,''); ?></title>

Put ' | ' inside the parentheses of wp_title to separate it with a vertical bar.
I think you can use characters other than vertical bars to separate them.

How to display [Page title | Blog name]

To bring the page title to the top, write as follows.

<title><?php wp_title(' | ',true,'right'); ?><?php bloginfo('name'); ?></title>

Adding 'right' inside the parentheses of wp_title moves the separator line to the right.

What happened to this blog?

As a result of various considerations based on the above, this site displays only [Page Title] for single article posts (single.php), and [Page Title | Blog Name] for other posts.

In the past, I blindly posted single articles using [page title | blog name], but I thought that for blogs, I could increase the SEO effect by using only [page title]. Ta.

Afterword

I briefly discussed how page titles should be displayed and how they should be displayed.

I don't know if you have the same idea as me, but there were quite a few famous blogs that only used [page title] when posting a single article.

I would like to measure the effect and verify it for a while.
