1, Flash Contents are not well indexed
Adobe Flash and SEO
At present there is no effective way to optimize Flash for search engines. The main problem is not that search engines cannot index Flash content; the real problem is that search engine spiders cannot identify the content structure. While in regular HTML you can structure keywords in a hierarchical way using semantic mark-up, in Flash this is quite difficult. Additionally it is difficult for search engines to determine what is visible and what is invisible to the end user. Since this could give way to “flash content spam”, search engines take the safe approach to give extremely low priority to flash indexed content.
To make things worse many designers make the mistake to bury text into images, making the indexing task from difficult to impossible. Maybe the worst possible error from designers is to bury links into Flash objects (the spider will follow the links conservatively). A Flash website navigation bar is the best way to prevent search engine from indexing your web site completely. Make no mistakes spiders will be able to follow links in Flash object, but the weight given to these links will be very low.
