The configured site title is used in multiple locations, including the browser title through the <title> tag, is read by third party crawlers (search engines, indexers, social networks). You should never leave this value blank.
To not have the title visible in the site’s header simply use the theme’s Header Content option and configure it accordingly.
thank you for your reply I have tried all the different theme settings and it does not allow me to have the title in the top bar in the internet browser and admit the text banner it create this is the one where the first letter is red. Perhaps this is only available in premium theme which were looking into thanks
