When I’m traveling and need to find the nearest Cracker Barrel, I go to crackerbarrel.com because I know that’s their website. When I need to search for something, I often go to google.com, even though I know I can just type my query in the URL bar. I instinctively associate a company or organization’s URL with its brand.
As you consider your church website’s URL, remember that it’s an extension of your "brand." We recently changed Concordia Technology Solutions’ URL from cts.cph.org to concordiatechnology.org because it more clearly stated our brand (there were also some SEO benefits, more on that in another blog post soon!).
