In creating this website, one of the elements we implemented was a slideshow. People like slideshows because they create an ambiance, an impressive feel for your site. In Mesa SEO, we dislike sliders because it hides content behind JS, and slows load times, and statistically does not contribute to conversion. The school of thought is that by having stuff scroll, users often are not able to get the entire message, and this is bad UI (user interface). The solutions include using arrows so users can navigate your scroll bars, but even better is a static graphic, which can set ambiance as well and has better conversion rate. However, as a designer, I know some of my clients really want a slider, so I make sure to judge each situation and create the site for the client I am working with and their demo, and not rigidly limit my creativity with slavish devotion to guidelines and best practice.
