Google is like the yellow pages. When you don’t know the address of the company you want, you search for it in google. And like the telephone, if you do know the address, you don’t look it up to dial, you just dial in the number. At the top of your internet browser (Chrome, Safari, Firefox etc.) you have an address bar. When we start to build a site, you type the address of your domain into that bar, and you will find your site.
The reason you aren’t finding it by searching is, we have likely only just created that domain name, and it takes a while for the search engines to find it. Later on, you will be able to put your company name in, and it should come up on the first page, and hopefully at the top of that page.
