Do robots crawl iframes?
Is it common for robots to crawl inside iframes? And how do they do that? Do they index it instantly or do they just 'remember' the URL and continue sometimes later? If there is an href/src link somewhere on an indexed (i.e. crawled ) HTML/XHTML page, it will get indexed. Whether or not the page is presented to the user via an iFrame is irrelevant. Iframes are easily crawled as others have pointed out. However I wanted to clarify that your page will not get "credit" for the iframed contents. So your page will not actually get indexed as containing the content -- it is merely a stepping stone
