Do pull quotes affect SEO positively or negatively?

[kyle21ct]

I like the design element of a pull quote to ad interest and highlight an important point. If I use an exact quote from the page in a pull quote on that page, does that negatively affect SEO as duplicate content?

Are there formatting or tagging methods that could help pull quotes to boost SEO?

For clarity, by "pull quote" I mean a stylized bit of text that floats on a page in such a way that the body text wraps around it. It is actual text (not text embedded in a graphic) but it behaves like an image with text wrapping around it.

Here's an example (in red on the right side):

I agree with Jesse. Pull quotes isn't the problem. Copy article and add nothing extra of value is the duplicate content problem.

Okay so beyond my Bill & Ted reference calling out an error in your article, I just want to say that there is nothing wrong with what you call "pull quotes" and they definitely will not negatively affect your SEO.

Repeating a sentence does not qualify as duplicate content. Duplicate content would be a problem if you had this exact same article on another page of your website. In other words, the duplication problems arise between pages, not within pages. Does this make sense?

Pull quotes work fine, it's all about user experience.
