Should my site's address begin with www?

In the vast majority of cases, it's no longer required, so is a personal preference. However, if you've been using www a long time already, or if you print your domain on posters or flyers and you want it to be unmistakably a url, then www can help.

Depending on your choice, we'll simply redirect visitors whether they include www or not. For example, a request for https://pageplay.com would be sent http://www.pageplay.com or a request for https://pageplay.com/page-title to https://www.pageplay.com/page-title

The opposite is true is you choose to drop the www.
