Although RealEstateDemos can produce Flash Tours with Flash Player controls, this Flash movie has a few benefits over the one with controls. For example, it loads faster, thereby not really requiring a preloader, although preloaders can be interesting and informative, but more importantly, the search engine robots that index the Internet have a hard time reading the content of Flash movies. In this type of Flash movie, i.e., without controls, RealEstateDemos can incorporate 'Meta Data' into the movie file, which enables the search engine robots to be able to read and index what a particular Flash movie is about, as well as other crucial data and information about the movie and the site it is from and/or referring to. As well, RealEstateDemos Flash movies without controls take up less vertical space, thereby leaving more visible content above the fold of the page, i.e., above the fold refers to what a viewer can see on the monitor without scrolling down.
