Editing the Top Description Before Domain Name in Search Engine

Please help, I really wish to edit the site description that appears at the top of my domain name before the site url (domain name) on search engine, (I am not talking about site title). I have two images attached to explain what I mean. The image for cbtpractice.com.ng is what I want to change to make it appear like the one in the second image.
