Melissa Tarquini of Boxes and Arrows wrote a good article about common myths that exist concerning designing a Web page that requires users to scroll down "below the fold." It's well written and well considered, but it's important to note what wasn't said just as much as what was, lest readers get the wrong impression.
Tarquini's principle claim is that "the fold doesn't matter in certain contexts." However, this claim is flat out wrong. The fact of the matter is, the fold does matter. Always. And Nielsen says so. But with all the compromises that must be made when designing websites, designing to put content below the fold might be the best option available. It certainly seems to be the case for the AOL portal page (which Tarquini mentions), where several titillating content regions perform well.
A more complete commentary of Nielsen's point is as follows:
"The change from 1994 [to 1997] is that scrolling is no longer a usability disaster for navigation pages. Scrolling still reduces usability, but all design involves trade-offs, and the argument against scrolling is no longer as strong as it used to be. Thus, pages that can be markedly improved with a scrolling design may be made as long as necessary, though it should be a rare exception to go beyond three screenfuls on an average monitor."
In fact, if we're to take the whole of Nielsen's position, much of Tarquini's thesis is about the exception to user behavior, not the rule. According to Prioritizing Web Usability, which Nielsen wrote with Hoa Loranger, for the first visit to a homepage, only 23% of users scrolled. On the fourth and later visits, that number fell to 14%.
However, on the search engine results page (which I would wager, with its dynamic content, compares more favorably to the type of page Tarquini was specifically talking about), 47% of users scrolled.
That's a difference in audience behavior large enough to make me reconsider how I design a page. It's important, then, to identify the type of page you are designing before making decisions based on blanket assumption that may or may not apply to everyone.
All this means is that when designing websites, you have to accommodate different things according to the goals of the organization and the wants, needs and tendencies of a diverse group of users. People don't all navigate websites in the same way. If you are going to design a website that will require scrolling to access certain types of content, be sure to put the highest priority content above the fold, conform to usability best practices (which Tarquini also mentioned), and don't confuse the ability to do something with the practice's acceptability.
Without a doubt, Tarquini's point applies foursquare to the types of pages she is specifically talking about, and given the user behavior she describes, it is apparent to me that, even without looking at the page, AOL is doing a fine job with it. Let's just be careful about the inferences we draw from her example. - Cam Beck
Note: To be fair to Tarquini, I think her article shows a fundamental understanding that the fold does
matter, because she points out later in the article, in general terms, several things that should always be above the fold. Her statement that we have "documented evidence that the fold really doesn't matter in certain contexts" should be read with the context of the entire article in mind.
