This plugin allows you to make multiple front end websites from just a single, simple installation of WordPress.
Suppose you have a WordPress site example.com. It contains 100 posts. You want to show some of them on cars.example.com, some on my-super-domain.com and some posts on mobiles.example.com. See? you can show content across multiple subdomains and even on separate domains.
How to do it? Very simple. To setup a new subdomain for example cars.example.com, do the following:
<ul>
<li>
First point cars.example.com to your main website server. This may require changing of DNS records. On many hosting providers this process is called create a “Domain Alias”. The target is that if you browse your new domain or subdomain, it should show the content as you see on your main site.
</li>
<li>
Create a new ‘Contributor’ type user.
</li>
<li>
Put https://cars.example.com in site url field and save.
</li>
<li>
Now, go in Posts and set that author to those posts which you want to show on cars.example.com.
</li>
<li>
That’s all. Now browse https://cars.example.com and you will see posts made by the contributor user of this site.
</li>
</ul>
