Our system provides a web front-end. A potential client would like to set up his own portal, and place our pages within his own pages, using iframes. He'd also like Google to index the joined content. I'm wondering if that's possible.
Note that since the client is going to own both his portal and ours, he can place both under the same domain. So the iframe will actually bringing content from the same website, and not from some unrelated source.
If this won't work, is there any alternative way to join content on the browser's end, in a way acceptable by search engines? Worst comes to worst he'd have to use our API and build the complete pages on his back end, but I'm looking for alternatives.
