Can I remove the links at the bottom my my web pages that say "Design a website" and "List Your Business" ?

Are these links at the bottom of my web pages removable? Having Homestead ads on my website makes it feel unprofessional. They would be expected on a free hosting plan, but this is a site I'm paying for.

Also, when I go to my website, the URL changes-- why is my domain name not showing?

I am happy with my Homestead package for the price, but it needs to look professional.
