Website Lists by Industry: Verified Company Websites (Domains)

Industry Intelligence Center · Updated: November 2025 · Reviewed by: SICCODE Research Team

When your growth strategy depends on reaching the right companies online, nothing is more valuable than a clean, verified list of company websites (domains) by industry. SICCODE’s website lists combine accurate SIC and NAICS classification with verified domains, enabling high-precision digital targeting, ABM, ad suppression, enrichment, and analytics. Whether you’re building retargeting audiences, mapping competitor ecosystems, or powering a data lake, verified domains are the backbone of modern B2B marketing.

What’s Included in a Website List

  • Company identity: Legal name, DBA (where available)
  • Verified website/domain: Root domain and normalized URL
  • Industry classification: Primary/secondary SIC & NAICS + industry description
  • Firmographics: Revenue range and employee count (where available)
  • Geography: Country, state/province, city, ZIP/Postal
  • Lineage & freshness: Last verified date / data source references

Why Verified Domains Matter

  • Precision targeting: Create high-match custom audiences for ads and ABM by industry, size, and region.
  • Suppression control: Exclude customers/partners from prospecting campaigns to reduce wasted spend.
  • Attribution & analytics: Tie web events and conversions back to verified companies and industries.
  • Data hygiene: Normalize and unify messy URLs and subdomains into a clean company-level domain.

Use Cases for Website Lists

  • Programmatic and paid social: Upload verified domains to build or exclude target cohorts.
  • SEO/Content intelligence: Map industry ecosystems to identify content gaps and backlink opportunities.
  • ABM + sales: Arm reps with accurate websites for research, personalization, and outreach.
  • Enrichment: Append verified domains to your CRM for dedupe, routing, and lead scoring.
