Who it is for2 questionsThis question needs attention now
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.
Service area1 question
One person wants a business nearby, while another needs a specialist who is willing to travel further. Your answers make clear where, and on what terms, you help customers.
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.
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.
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.
