We have created an web application that gives the client the possibility to use his websites as an online showroom (cars, bikes, etc etc).
What is offered is photo's, information about the vehicles and so on.
However, we would like to offer this as an iframe rather then developing plugins for certain CMS systems (Drupal, WordPress etc etc) or giving an file_get_contents/curl method.
The only downside we can think of is that the content within the iframe isn't going to be indexed by Google.
Is it possible to let it be indexed to the parent webpage? So that the content of the iframe belongs to Domain A.
We've tried it with canonical tags but this didn't work.
Any ideas or is this just not possible?.
