Keep it updated but make your update count
Updating your website is a great but this initiative can easily pale into insignificance if no one accept you sees what you have done. Similarly, if the update does not cause your visitors to takes some kind of action, such as contact you, buy or sign up, then what purpose does it actually serve?
Keep it updated and target traffic and conversion
Many websites update regularly but lose track of why they are doing what they do. Consequently they lose traffic and have a poor conversion rate. When you update your site try to make sure your update gets found by Google to ensure the people its targeted at, get it. Craft your message to compel your visitors to take some action, whether it be to order, download or contact you.
Keep it updated with insight using Google Analytics

It measures how your site is being used, sales and conversions, and will lets you know how effective your strategy to keep it updated has been. The insight you get will help you to focus your efforts on the parts of your website that are failing to perform.
