Website Visitor Identification

Identify anonymous website visitors at the company or contact level using reverse-IP and pixel-based identification tools

Error Handling

  • Rate limits: RB2B allows 100 req/min, Koala 60 req/min, Clearbit 600 req/min. Implement exponential backoff on 429 responses.
  • No match found: Not every visitor can be identified. Company-level tools match 50-70% of B2B traffic; contact-level tools match 15-40%. Expect misses.
  • Bot traffic: Filter out known bot user agents before counting visitors. Most tools do this automatically but verify by checking for suspiciously high page counts from single IPs.
  • GDPR/Privacy: Visitor identification must comply with local privacy laws. Ensure your cookie consent banner covers analytics and identification pixels. Koala and RB2B operate on first-party data principles but consult legal counsel for your jurisdiction.
