The meta title is the HTML element that labels a webpage and appears in the browser tab and search engine results pages.

Generally, when we optimize your website with PageSpeed Insights, you will see a missing <title> in the result. If you use WordPress, you can solve this problem by doing as below:

Method 1: add_theme_support( ‘title-tag’ ) to functions.php

in the theme setup function, you will see:

add_action( 'after_setup_theme', 'theme_setup' );

function theme_setup() {

add_theme_support( 'title-tag' );

}

If Method 1 does not work, you can follow Method 2.

Method 2: going to header.php and adding this in <head>

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

when you add this, it is going to improve your SEO and Accessibility in your website.
