Does iFrame effects SEO?

[har.sinha]

I think there is a misunderstanding about frames affect SEO that I've heard from a lot of people. There is no inherent penalty for having iframes on your site, as there are several legitimate uses for them. There are iframes in Gmail for example. but as Northcutt said, The content of an iframe isn't part of the parent page and isn't going to be indexed as such (if at all), so that could be problematic.
