Traffic
Traffic: people search the symptom before the part
The search that precedes an RV purchase is usually a description of something going wrong, phrased the way an owner would say it rather than the way a catalog would. Nobody types the name of a component they have never heard of. They describe the smell, the noise, the reading on the panel or the thing that will not move. Stores that publish a genuine problem library, one page per symptom, explaining causes in order of likelihood, what to check first and which parts solve which cause, collect that demand for years. The products are then linked from within the explanation rather than pushed at the reader, which is why these pages convert as well as they rank.
