Although there are some web hosting companies doing such practices, Marble Host will NEVER place ads on your website. Clients of our web hosting services can enjoy 100% bannerless hosting.
You can also run your own ads on your website. You can profit from your traffic by placing AdSense, some ad network banners or any other kind of advertisement on your website. There are absolutely no restrictions -- your website belongs to you and you will always have its content in your hands.
