Traffic: the laptop model is the search
The most valuable query in this niche names a device. A bag for a specific sixteen inch laptop, a sleeve for a particular tablet, a case for a machine that just changed dimensions in a new generation. That demand renews every time a manufacturer redesigns a chassis, and almost no bag brand builds pages for it. A device fit page for each popular model, listing the machine's dimensions and which bags in the range take it with clearance, ranks quickly because the competition is thin and the intent is unambiguous. Around that sit the professional use collections, commute, business travel, court and site work, each written for the day the bag has to survive rather than for the material it is made from.
