How I can upload own website
To make your own website, you will first need a web host server to upload to (which you might need to pay for), and buy a domain name as well. There are many Web Hosting + Domain packages that you can buy from various companies online just through a quick internet search.
If you would like a free website, you can sign up with websites like www.blogger.com or www.wordpress.com and choose a template for your website or customize your own. Note that your domain name will have the website's names in it as well, e.g. 'you.blogger.com' or 'you.wordpress.com'.
Once you have the space and domain name, you have to build your site. When it is ready, you need to use an FTP program to upload it to the web space.
