『GoogleはiFrameにペナルティを与えない』:GoogleGuy

One of those tangents was that google would penalize pages that had iframes. I've never heard the suggestion that google would penalize for iframes before reading it in the thread. Plenty of legit sites use iframes, so it wouldn't make sense to penalize for it. Powdork gave the right response in message 337 of the first Bourbon thread. Now I can easily believe that some search engine spiders would have trouble with iframes just like some spiders have trouble with frames. But I wouldn't expect iframes to cause any penalties.

iframeを利用しているからといって、それだけの理由でGoogleはペナルティを与えたりしない。多くのきちんとしたサイトもiframeを使っている。
