Find Beta testers

First of all, you need to find beta testers for your site - Ideally, the beta testers should be similar to your site's target audience.

You can create an on-line application (using Forms) where potential beta testers can register, or you can go to Web Discussion Forums where you can invite users to beta test your site. Whichever way you decide to "recruit" beta testers, make sure that they meet a certain criteria, such as: Are they similar to the site's target audience? Speed at which they connect to the Internet. What Browsers do they use, etc.

Get feedback

As always, listen to what the beta testers tell you. It is extremely important that you monitor their feedback because it represents what your site's audience will think about your site. Not paying attention to their comments and suggestions really defeats the purpose of having a beta test program.

Also, make the necessary corrections/modifications to your site swiftly (if they are necessary) - You don't want to be overwhelmed with suggestions because then you may overlook important details and issues that need to be taken care of.

It is best that you create an e-mail address where the beta testers can send their feedback. Something like feedback@yoursite.com or beta@yoursite.com. This will make it easier for you to keep track of the feedback your receive.
