Who it is for2 questions
A private customer with a small job is looking for something different from a buyer with a large project. By clarifying who you work for, you help AI judge which searchers your business suits.
Lead times and availability1 question
A rush job calls for a different solution than a project for next year. That’s why we ask about your schedule, usual lead times and room for urgent requests.
Quality and guarantees3 questionsThis question needs attention now
Anyone comparing businesses also looks for certainty. How long will something last? What happens if there’s a problem? Your answers help AI explain better what customers can expect.
Certifications and labels1 question
For some searchers a quality mark is a plus; for others a specific certification is a hard requirement. That’s why we map out which accreditations you hold and what they cover.
Experience and references2 questions
“Has this business done something like this before?” A searcher wants to see recognisable examples. Your projects and references give AI concrete information about the experience you bring.
Sustainability1 question
One person looks for reused materials, another wants less waste or a product that lasts longer. These questions make concrete which sustainable choices your business offers.
