I asked her why she was registering all of these domains.
Turns out that a web tutor told her that “having multiple domain names all going to the same web-site was an easy cost effective way of getting high up on the search engines.”
That’s not correct
If you register multiple domain names – unless that are very generic domains like cars.com (and that would cost you million$) – then to get a benefit in search engines you need to develop sites on each and every domain name.
Register 1 Domain And Stick With It
My advice is this: Register 1 domain name and focus all of your efforts and resources on that.
Developing 10 web sites to all do the same thing is a false economy and will waste your time, energy and money.
