Flash content isn’t great for SEO (let alone usability) because search engines can’t crawl the content in it. Thankfully, SWFObject2 can help out by delivering alternate content when a user doesn’t have Flash installed, a search engine visits the page, or when someone deliberately turns Flash off just to spite webmasters who still use it on their sites.
I’ve created a test using SWFObject to either deliver a Flash slideshow or HTML content based on the visitor’s capabilities. Once Google hits it, I’m going to see if the text from my alternate content shows up. (Note: The page has no meta description, so I’m hoping Google will pull a rich snippet from the alt content).
