I have an iframe on my site and Google gave the page a Rank 1 for 2 weeks then changed it down to a GRAYBAR and now after 2 months the page still doesnt show up in the SERPS so, at least for my case, it seems GooooooGoo doesnt like iframes.

Thats my story and Im sticking to it.

It is true that Google is not very fond of iframes. When you have a page with an iframe should considered them as 2 separate pages. Google will index them separately. It is possible that it checks the content of the iframe too but the guidelines of Google suggest to avoid them.

Recently iframes have been suggested to be used for pagerank sculpting (nofollow is not an option any more). I strongly believe that its not the best solution as it is probable that they receive pagerank.

If you have iframes you should consider adding additional content to the actual page in question to supplement the content of the iframe. As bbriniotis indicated, the SEs will see two separate pages therefore it is difficult for them to determine context with a significant part of the message being excised from the page.

My client is using an iframe for some key content on their site. The parent is on a different domain than the frame.

My concern is that I expect the iframe page to rank and show up in the SERPs. Anyone arriving at the iframe page will see an unformatted page without navigation.

I was thinking of using document.referrer to add some basic navigation for anyone coming via search. What I'd rather do is send anyone not coming from the parent domain to the parent domain, thereby displaying the iframe for a second time.

Would this work? Would it be looked at as spam? Could you give me an example of the code?
