Domain mapping is a process that you’ll need if you have URLs parked elsewhere that you want to link to your site or redirect completely. Mapping the domain can seem tricky at first, but following the instructions will get you there.

Here are a few reasons to map your domain:

You have an existing site and want to transfer the CMS to WordPress but keep your URL. This could be purely because you’ve heard about the great things at WordPress and want to try it for yourself. If you’ve built up the reputation and links to a URL, you won’t want to start again completely. So mapping it to a new CMS could be the perfect option.
You want to point multiple domains to a primary hosting account. For instance, if you have purchased multiple domains to match various search queries or misspellings, your customer will always end up at www.yourdomain.com – your primary domain – and see the content that you have planned for them to see first.
You want to point your URL to a sub-level page of your site. If you want your blog to be the first thing visitors see when they land on your site, you can set the domain to your blog without having “blog” in the URL, for example. This also works if your blog is hosted elsewhere and you want to link two domains together.

If this is what you’re trying to achieve and you’re working with WordPress or want to transfer to WordPress, then this article is for you.
