The thing that you will need is a domain from a cheap web hosting services. You can easily get a custom domain for nearly $10 or less.
So now i assume you have a custom domain so let’s get started. Go to Google Apps and under menu name solution select Google Apps (Free) >> Get started.
Now you will be required to input your domain name and other details. After filling all the details Google will provide you two options. Going “EXPRESS” way or “CUSTOM”. I suggest you select the “EXPRESS” as it is easy and fast to set up.
After doing that you will get option’s like shown From that choose “VERIFY DOMAIN OWNERSHIP” and click NEXT.
For verifying the domain you will be given “Alternative methods” from which the one most preferable for a blogger blog is “Add a meta tag to your site's home page”. When you select this option you will be given a meta tag like shown below.
<meta name="google-site-verification" content="MiDASwsM-zcVLsZpYach5gQ_Umwk5GhzyJdN3rXvQ5da8" />
Try sending any email and you will see that it is delivered with your domain name. Remember all this you need a domain which you can easily get from Web hosting service.Happy blogging. :)
