In early 2008 Google announced that they have started indexing Flash content to greater height and they claimed that Google might see the text appear in the Flash website as visitor might see. But still optimizing the FLASH website is a real nightmare for many SEO geeks in the industry. We can still read in blogs and discussion forums people discussing and throwing away ideas not to use FLASH in the website and they treat that as a real suicide in SEO field.
To make things simpler, Adobe launced a newsite to help with SEO process. Getting started with the FlashSEO they have provided few excellent SEO articles,
- Search optimization checklist for RIAs
- Adobe Flash Player version checking protocol
- Enhanced search indexing of SWF content
