The easiest way to test if your site is visible on Google is to go to Google and type in "site:[mydomain.com]" and see if your website appears. For example, to check if Golfing4u.co.uk was indexed, I would type "site:golfing4u.co.uk" into search engines. If your website isn't visible after this search, it means that your website isn't yet found on Google at the moment.
