Then when you come back to that website, because you want to reference something that you didn’t quite catch in your first visit, you become a bit annoyed with the fact that you have to wade through all that flashiness just to get to the content you’re seeking.
While on your initial visit you viewed the dynamic flashy nature of the website as impressive and quite entertaining, once past that experience on a return visit the site seems less helpful as a source for pertinent content because the site design and navigation is geared toward brand new visitors and not return visitors.
The ideal answer is likely a better balance of a site that has some flare to it and a site that has a clean design and functional user experience allowing the user to find what they’re looking for. However, if you’re going to err one way or another, I would suggesting erring on the side of simple, clean and functional. Flare and pizazz can always be added later, but if visitors arrive on your site and have trouble understanding the site, what your company does or how to find the information they’re seeking then no amount of entertaining motion graphics are going to convince that visitor to return and buy something from you.
Keep the information on your website/blogsite clear, concise and easy to find to communicate your company’s brand messages. If you can add some flash and entertainment value, great, but be sure a solid foundation is firmly in place first.
