Hi Tommy — for local trades with thin digital footprints, we’ve found custom research outside Clay works better before any enrichment. We usually rely on manual size proxies (team size from LinkedIn, years in business, service area coverage, number of locations, reviews volume), then bring only qualified leads into Clay for light enrichment. Signals like repeat job postings, Google reviews velocity, and licensing records tend to be more reliable than firmographics. Happy to share more if useful.
