Our webpage has been embedded in others website using iframe. Does this hurts us in rankings?

[vtmoz]

Hi all,

One of our partners have embedded our webpage in their website using iframe such a way that anybody can browse to any page of our website from their website. It's said that content in iframes will not get indexed. But when I Google for h1 tag of our embedded webpage, I can see their website in SERP but not ours which is original. How it's been indexed? Is this hurting us in rankings?

Thanks

It is possible for Google to index content within an iframe. There are some solutions to stop it indexing the content, if possible I would get your partner to add a canonical to your page to stop the content competing. However, this really depends on what the purpose of the page is and what you are able to do technically.

This is a really good case study explaining the different ways to index iframes by search laboratory.
