Gone are the days of your youth when you could go on the yearly hunt for Easter eggs. Not to worry, you don't have to leave the excitement of discovery behind. In the past 35 years, there have been hidden inside jokes in video games, albums and DVD special features. As adults, we can still find subtle winks designated only for those people who look deeper than most.
Not only can you enjoy random references through Easter eggs someone else has created, but if you are building a site for personal reasons or even a business, you can make your own.
If you run a business site, you need to be taken seriously, but that doesn't mean that you shouldn't show your personality somewhere on your site. Don't bog down your home page with links, but add a few to your mission statement or About Us page. Many readers see a link and avoid it, thinking that an annoying advertisement will pop up. Yet, if they click on one of your hyperlinks, reward them with a link to a funny meme or picture. However, you should make that hyperlink go to one of your own pages so people don't actually leave your site.
Custom 404 Pages
Website builders should come with the feature to create a custom 404 page. While creating a stand-by page might feel like a waste, it at least informs your reader that the information they seek cannot be found. That page doesn't need to be a dead end. Most readers instinctively just click on the back button. In the 2.5 seconds they remain on the page, you might as well make it enjoyable. Why not throw in a meme of Gandalf from Lord of the Rings telling the reader "You shall not pass!" or a picture of an emotional hipster with the text, "I liked 404 pages before they were cool."
Google is the king of mini-games. They randomly use their logo and search bar to do daily games. This Easter egg may require some coding, but you can find it all online. One example of a mini-game is to change your site's background to a classic game like Mario or Sonic the Hedgehog. Readers may only briefly look and acknowledge that you've changed your background, but if they scroll to the bottom of the page, they'll find that they can control a player or missile command in the attempt to shoot down asteroids.
Video Prank Tutorials
If you don't mind taking a few risks with your readers' patience, feel free to add in a random video to your tutorials page. Your new client may need help in setting up an account, so add a Rick Astley video to Rick-Roll them. At that point, you will have lured them in to clicking on your actual tutorial videos just to see if there are any other Easter eggs.
Easter eggs are anything but unprofessional. They show your readers that you've taken the time to create an experience. Your goal is to have repeat readers and good word of mouth. Throwing in a few online, inside jokes is one of the best ways to do that.
