Changing the site title in the browser tab

Hi! I hope you can help me with this matter.

I need help changing the info showing in my browser.

Right now, when I visit any post contained in my site, my broweser tab shows the title of my post. I want to change such that when someone clicks on one of my posts, the browser tab will show “(post title) – The Urban Roamer (the name of my site btw)”

Any info you can share to help me on this would be appreciated.

Thanks!
