Yes, Like Bob said, you need a different domain for each website - which you will need to purchase separately.

Luckily, all of your websites are contained within wealthy affiliate.
So, once you bought your domain name, you simply change the DNS settings and transfer the site, which will then show up in your siterubix site manager.
At this point, both your '.siterubix.com' domain and your 'mydomaingoeshere.com' domain will show up, although you will be working from your 'mydomaingoeshere.com' domain log in.

So, each time you build a new site, you do the same thing again and you will start to see your site manager fill up.

Just be careful not to overload yourself as it can become quite stressful :)

Good luck to you!

Yes, but start with just one. One website is more than enough to keep you busy for months. It's hard to manage more than one in the beginning. Focus.

Thankyou. That helps.

A domain name should reflect, in some way, the niche that you're targeting. By having different niches on the separate sites, you can focus better on that area and not confuse your readers with unrelated content mixed on a single site. As fitmomuv3 says, you'll then build out multiple pages on each site. (As an aside, it might be best to concentrate on one site first before extending your efforts across other niches.)

Also, don't get too concerned with having multiple domain names -- they're fairly cheap to register ($10 or less per year). Since you're a premium member, you can host all of your domains here at WA at no cost beyond your premium membership.

For each website, yes, you need to purchase a different domain. (ex. mycoolthings.com or automotivetips.com) WITHIN each website, you will have multiple pages (About me, Contact us, Information etc.) which will be populated with information, and posts on a regular basis to expand on certain areas. Hope this makes sense.
