Content that changes at regular intervals based on a database or the user's actions.
Dynamic content is the opposite of static content which is stationary and it can change depending upon different factors. Dynamic content can sometimes penalize a website with search engines since the content is more difficult to index, but it more than makes up for that in versatility and speed.
iMpro is very accomplished at developing web presences that address the specific requirements of its clients whether it be static or an ever changing community. Private sites, public sites, protected environments, social communities, marketing efforts, ecommerce, blogs, intranet, hubs...you name it.
