SEO & CSS Display None: Is it Bad To Hide Content
The body content on any page is always important to help that page rank for the topic and keywords being discussed. Good SEO best practices are to always have your content in plain text (never in flash of images), have good quality content above the fold and ensure your pages have enough content on them. The last point, having enough content on a page, is usually a pain point with a lot of websites. Sites like to be flashy and image heavy to capture the users interest and this usually limits the amount of quality text on a page.
