I saw a commercial on the air that stopped me: There was no audio, no music, just a website. The URL was www.metrocatholicschools.com For some reason, maybe because I was never good at Wheel of Fortune, I couldn’t read it or decide who placed the ad (here’s a hint, my children go to catholic schools).
Maybe you can read it. It is actually, www.MetroCatholicSchools.com. This reminded me that we only have seconds to communicate or the moment is lost–sometimes forever. Instant recognition is imperative.
So here is a simple trick: Capitalize the real words of your URL (Uniform Resource Locator). 
The capital letters will not impact the navigation. They will improve your recognition and enhance communicating your URL name. And in advertising, since many people are not just waiting by the TV, radio or mailbox with a pen and paper, it will help people remember your URL name so they can call it up later.
Capitalization helps us make sense of the name. If you have a short URL, it may not make much of a difference; however, URLs are getting longer and longer because most short URLs are already taken.
Can you read this URL? www.capitalizerealwordsinyoururl.org.
Now try: www.CapitalizeRealWordsInYourURL.org. (This is not a real site.)
Even the most computer-adroit teenager who text-messages and IMs will appreciate being able to read the URL, even if it is only on some subconscious level.
Another reason: What is www.molestationnursery.com? Is it MolestationNursery.com or MoleStationNursery.com; or TheRapistFinder.com or TherapistFinder.com; ExpertSexChange.com or ExpertsExchange.com? These are all real URLs.
