First thing: it's better to have no website than one that's out of date. Going to a church's website in September and finding the summer schedule ... that's a message we don't want to send. Basically it says "we don't know what a website is for."
Beyond that, though -- what's on the website? Does it show buildings? If you expect the over-50 set to be the main audience, buildings are OK. Buildings, especially old buildings, say "we've been around, we're going to be here, your donations aren't going to a rented shack somewhere."
But if you want the under-40 crowd (kids!) to learn about you from your website, what do you want them to know? Besides basic information like where you are and what time services start, what meta-message do we want to send? "We care about people"? Then we want thoughtful or happy faces -- faces that are younger than 40. "Community"? Groups. If we want to emphasize celebration, empathic listening, contemplative worship, whatever -- pictures are worth thousands of words. If I were a webmaster I'd consider short video clips too.
But don't forget to keep the website current. Otherwise please take it down.
