What you’ll find may be surprising. I found that of the top 20 Christian churches, only 3 actively use images of Jesus Christ on their site. Most churches don’t visually emphasize church doctrine or principles, but rather emphasize recent news in the church or upcoming conventions, concerts, and speaking series. Most of the churches choose to advertise programs or other websites and they promote their bookstores and other products for purchase. Some churches emphasize healthy living, taking care of the poor, and providing relief during disasters. Some have a really strong emphasis on the leadership of their church, directing readers to church hierarchy and important people.
One thing you’ll want to notice from each church is whether or not they are incorporated. You’ll find an interesting connection between the churches that have a “.com” website address and their visual emphasis on money-making conventions. The .org sites tend to be focused more on doctrinal and faith-based issues (but not all).
