best answer to this are two different links:
https://www.axew3.com/w3/forum
and
https://www.axew3.com/w3/forums/
you see the phpBB iframed into wordpress on first link.
This link point to a wp page named forum, which just display an iframe inside.
What an iframe is and how spiders look to it?
It is a tag that retrieve a resource (phpbb in this case) and display it on page as separate content/window. It is not part of the page, nor will be considered as part of the page by spiders. Spiders just can follow the related href where it point in case (the real url of phpBB, or any other resource/url that the iframe point to).
The unique problem was represented by widgets or shortcodes that display last topics: all pointing to same wordpress page, with different kind of links.
However this problem has been resolved with a little trick time ago: spiders see the real phpBB url, while users, if iframe links activated, are redirected to correct wp page with the iframed phpBB. You can check this behavior how work with easy javascript applied, at axew3.com home. Pass mouse over a link: it display the real url to phpBB, until you do not click over or move out the mouse from link and return over. the url will result switched the one of the iframe page at this time.
In short: how iframe affect spiders or users? In no way.
The code about iframe has been just further more improved at date of this post, and i hope that this will be the right time of this test: all should result perfect, but i will test little more before to release.
Cheers!
