Common Block by ISP / ASN Mistakes for B2B Stores
- 1 Blocking too broadly — start with targeted rules and expand based on data rather than blocking entire regions your b2b customers might come from
- 2 Not reviewing blocked traffic logs — regular reviews help you catch false positives and discover new threat patterns
- 3 Setting up blocking once and forgetting it — threat patterns change, and your b2b store's rules should evolve with them
- 4 Ignoring the analytics impact — blocking bad traffic improves your data quality, but only if you re-baseline your metrics after implementation
- 5 Not combining blocking methods — layered protection using multiple blocking types provides much stronger security than any single method

Review your blocking reports weekly for the first month, then monthly. Look for new patterns, adjust rules for seasonal changes in your b2b market, and expand protection as you identify new threat sources.
