Surprisingly often, a seemingly un-noteworthy article makes it into the top five or so articles by pageview count and remains there. Currently, for example, AMGTV[1] has been on the Trending feed card for English Wikipedia for some times. The persistence of articles like this in the upper ranks supports a suspicion that its ranking is being inflated by bot traffic.
