How people are getting benifit on free websites?

[Jake]

Most free hosts earn revenue with a combination of advertising and paid upgrades. User content is the engine that drives the ad revenue by attracting visitors.

You can register a site domain name through an official registrar like godaddy.com or namecheap.com for about $12 a year. You effectively own the name as long as you pay the annual renewal, corporations may pay 10 years in advance.

The site might use a free host with the custom domain or paid hosting providing better performance and control, typically costing $4 to $9 a month on a shared server.
