If it's the same data every time, then one view is enough (maybe a return to verify the info). Compare a personal webpage to a webjournal. For both sites, you have an idea what sort of content will be there -- content relating to the creator's life. With the journal, however, there is no certainty as to the exact content, even if you have been to the site in the past. A person's personal site requires one, maybe two, visits, but a journal means that at any time, something new may be there.
Consider the Receipt site: had the site just been scanned images of all my receipts, one visit would be enough. However, since the content changes moment-by-moment, thanks to visitor comments, there is ample reason to return to see what has changed.
The faster the content changes, the more often a user has to return to keep updated on the condition of the site. Uncertainty makes a visitor return, and uncertainty is what brings website traffic.
