Let’s sign in to google’s webmaster tool section. The link « add a site » is found right at the bottom center of the page, where you log in to. You click the link, and fill up the field that pops out, with the name of the website that you want to submit.
You will be given a few choices, but I found that the easiest is to upload a file using ftp.
Personally, I download the html file google provides, save it back to my site’s home folder (computer), and then upload to my site’s home folder (server).
Once done, you can submit the sitemap to Google. It is assumed that you have already added your site to google by now. Also, you have your xml sitemap created at http://www.yoursite.com/sitemap.xml. Submit that to google, you have all the links to do that, that you have discovered after submitting your site to Google above.
