Hello,

What role does this html, javascript, css, flash, plays in seo. I know little bit of HTML that we should make pages of that only. But this css and javascript what about that. Well I know that if we make website in flash then spider not read flash website.

Thanks.

Google has been upgrading their technology and they now do check into SOME javascript and Flash content. You can use Site Search [webmasterworld.com] to discover more discussions about this. Here are just a few threads:

It's just at the early days, and these technologies are still not the best way to get well ranked - but things are changing.
