Your licence number builds trust. Homeowners are encouraged to check a builder's licence before they sign anything. NSW rules generally require a contractor licence number in advertising for residential building work, so we put yours on every landing page and, where it fits, in the ads. General information, not legal advice. Check the current rules with NSW Fair Trading or the Building Commission NSW.
Negatives cut the rest. Building searches attract students, job seekers, owner-builders after advice and people hunting free plans. Our starting list for builder marketing blocks those, then we add more every week from what people actually typed.
