does anyone have some experience how Flash Website do with goole ranking? I have read some information which makes me believe WebCrawlers have trouble reading Flash Website contend.
Flash is a threat in SEO perspective. Major search engines such as Google, Yahoo and Bing cannot read content within flash, it will only be seen as an "object". Most of websites with a full flash and no context have a poor ranking, unless you have a much stronger backlinks compared to common website like 200%. If you have to use flash, please use it as a part of website only. You should consider to put more textual beside the flash to help for index and ranking.
not only is flash a headache when you're trying to do SEO (although FLASH IS NOW INDEXED BY GOOGLE) you have to remember that initial SEO is a trial and error process. If you want to spend time redoing your flash movies and all, then it's fine. most people, however do not have that luxury.
if you are going to optimize a flash based website then use embed code for it. it will help you to get some rankings.
