1 maybe you have done something to encourage visitors stay on the site longer.
2 maybe you have done something to make pages download quicker so that visitors don't move on before the ads display.
Lots of other possibilities of course.
This caused me huge problems last month from so-called sites offering services to gaming sites and myspace users by hotlinking through Google images and still referencing the actual url thereby generating page images.
Google Analytics does not pick up on this therefore my traffic for November had a huge increase with absolutely no extra earnings.
If 5% is a few hundred or maybe even a few thousand pages, it could be just a shift in the source of traffic.
For example, visitors from search engine A might visit more pages per visit than visitors from search engine B. So if you get a spike in traffic from search engine A that could be the answer.
Or you might have gotten a link from an active forum or such, those can generate a lot of traffic sometimes.
If it continues for a week or more that's one thing, if it drops off rapidly in the next few days, that's another.
