The hour is the search. «Midday», «twice a day» and «after work» are the real keywords, because the problem is a time slot rather than a dog.
The street name beats the city. Somebody looking for a walker wants a person from their own neighbourhood, and districts in the text bring enquiries a city page never gets.
Holidays create a second, entirely different demand. «Dog care while away» is typed weeks in advance and has nothing to do with the daily walk.
Trust is the reason behind the search. «Dog walker reviews» and «how does the key handover work» come before every booking and go almost entirely unanswered.
The difficult dog is an unclaimed niche. Reactive and fearful dogs make their owners search explicitly, because two providers have already said no.
Price gets searched outright. «How much does dog walking cost» with no answer sends the person to the next page, and one figure in prose keeps them here.
