Creating and publishing a website is not always a cheap endeavor. Most people don’t realize just how many things they have to pay for to get a site up and running. Not only do you have to pay for development, but there’s also web hosting and domain registration to worry about. Depending on the size and capabilities of your site, your website costs can start adding up pretty quickly.
Do not use more than one domain for a website. The result of using multiple domains is that you will not be as effective on Google, Bing, and other search engines. It can be very confusing for your customers as well. Domain names should be unique, to the point, favoring.com, and not changed or manipulated over time.
