There seems to be quite a few articles out there that say iframes cause problems with organic search and that the various bots can't/won't crawl them. Most of the articles are a few years old (including Moz's video sitemap article). I'm wondering if this is still the case with YouTube/Vimeo/etc videos, all of which only offer iFrames as an embed option. I have a hard time believing that a Google property (YT) would offer an embed option that it's own bot couldn't crawl. However, let me know if that is in fact the case. Thanks! Jim
