I know adding rel="nofollow" to links prevents Google from following that link and prevents leaking of link juice, but I had a few questions on how far this goes with other elements.
I've searched and found [webmasterworld.com
...] but this is old (from 2003) and wanted some clarification.
1 - Do external images leak link juice? The link above says people hotlinking to a hosted image of yours can boost your PR, so does that mean having external images on your site can leak link juice?
2 - Do external iframes leak link juice? If I were to include an iframe on one of my domains that is hosted on another, would this leak link juice to that domain? For example, abcde.com has an iframe of a fghij.net page.
Appreciate any feedback, thanks!
