Do google index iframes?
Well my experience says it does.. We had an adserver which used to serve ads in an iframe into our websites. One fine day our System admin noticed that a page from our internal ip in google’s index.
Digging on to the above, we found that it was the page which was shown in other sites within iframes. There was no other way google could have indexed our page !!
Any other arguments? Shout here.. We will get into a strong conclusion !! 🙂
