This is a bit of a SEO question. If you search something on Google on a mobile device you see something like this:
How do you edit or change the word inside the red circle? I thought it reflected what you have inside the title meta tag but it doesn't seem to be the case.
Add the below meta
tags in the header.php file (Appearance -> Theme File Editor -> Header.php)
Note: You can also access and edit the header.php file from wp-content/themes/{YOUR_THEME}/header.php via FTP/SSH
og:title
is responsible for title shown in Google search results. For more details check out this link https://ogp.me/
<head>
<meta property="og:title" content="Your Title" />
<meta property="og:image" content="Your Image URL" />
<meta property="og:description" content="Description " />
<meta property="og:site_name" content="My Website, Inc." />
</head>
Alternate Method : you can use Meta Tag Manager to edit meta tag via plugin
