How to read this. A first-place recommendation earns 10 points, second place 9, down to 1 point for tenth. An absence earns zero. We average within each platform, then across platforms and studies, and scale to 100. Each study has equal weight.
Only valid ranking responses count. Qualification requires at least two studies and three response appearances. Published names are grouped by case and punctuation; distinct name variants remain separate. A broad score can favor providers serving many household needs. It is not a customer rating, service quote, workmanship guarantee, or assessment of local qualifications.
