This church (remaining nameless) has had this sign on its homepage for at least several years:

The site (which is one page) has this encouragement:

For anyone who might have been keeping an eye on the site, it's been a pretty disappointing wait! These signs on websites are bad for a number of reasons.

As one study concluded:

"Users also felt that "under construction" signs were disrespectful of their time."

Tony explains neatly on Twitter:

"If it wasn't important enough to get it ready for launch, you're never going to do it".

The answer is simple - remove the 'under construction' sign.

As another author explained:

"There is really no point in saying that your web page is "under construction". If your page is not yet finished, then you should not be publishing it."

Churches are often culprits with the 'under construction' banners. When the person who started the website leaves the church, the website doesn't receive attention for weeks, months, or even years. It's much better to launch a simple website that you build on, than to promise much, and never deliver.
 

In my opinion, anyone who has anything to do with a church website should read 'Don't Make Me Think' by Steve Krug. As websites become increasingly important for our mission, it's important that we learn how to make them user-friendly. 

And if you're yet to be convinced, your church needs a good website.
