In de Webmasters/Site owners Help schrijft Google:
Note that while Google can index the content of Flash files, other search engines may not be able to. Providing text equivalents of these files will help other search engines crawl and index your content. You could also consider using sIFR (Scalable Inman Flash Replacement). sIFR (an open-source project) lets webmasters replace text elements with Flash equivalents. Using this technique, content and navigation is displayed by an embedded Flash object but, because the content is contained in the HTML source, it can be read by non-Flash users (including search engines).
Het lijkt me dus veilig. Kan je daar wat mee?
