Perhaps one of the most well known written rule of SEO
iswas to never use flash to build your contents since search engines only crawls and index text. Flash has always been popular due to its simplicity in building vector graphics, games, animations and rich media. But the tradeoff (at least in the eyes of SEOs) has always been that these contents gets no love from the search engines.
This rule might need to be rewritten as Google has announced that they are now crawling and indexing flash content. It ain’t perfect yet, but we know we’re getting there.
Flash publishers can now probably ask for more pay 🙂
