Site Title, Tagline and Email
Your site title is what shows in the top bar of your browser after the page name. When you’re on the homepage of your site, your site title is followed by the site’s tagline.
Modify your site’s title by going to Settings > General in the admin area as shown
Your site title and tagline are the first two items on the page
Alternately for the site title, you can chose to make your own site title within the Customizer by going to “Appearance” > “Customize” in the /wp-admin area.
If you have a short title, you have the option to use a single line title and if you have a longer title, you have the option to make the site title span two lines and chose which text goes in which position.
