Go to google webmaster tool and download the html page to your desktop.
Login into your cpanel, click file manager and click ok. When it opens, click on public_html, when it opens, click on upload file, then it will open in a different window, when that opens, browse the google html page you downloaded, then allow it to upload(which will take about 10 seconds)
Then go to google webmaster tool and and click verify link, google will then verify that you own the site. That is all.
