Cloudflare™ Guides and Fixes

Case studies

• Unmasking a scraping campaign hidden behind residential bots
  Unique visitors jumping from 45,000 to over 800,000 a day with page views flat: the reading that exposed the campaign, and the four-layer answer.

Bot protection & security

• Fix Cloudflare Bot Fight Mode false positives
  Challenge loops, blocked real users, silently dropped webhooks: causes and surgical fixes.
• Block AI crawlers while keeping Googlebot
  Stop GPTBot, ClaudeBot and Bytespider with custom rules without hurting your SEO.
• Fix security rule false positives blocking signups and checkouts
  Tune security rules that reject legitimate customers during registration, login and payment.

  Rate limiting and bot rules to protect registration and login forms.
• Unblock Googlebot and protect SEO rankings
  Recover from accidental search crawler blocks and verify Googlebot access.

Performance & caching

• Fix Cloudflare cache not working and low hit ratio
  Why the cache bypasses your origin content: cookies, headers, cache rules and origin setup.
• Fix Cloudflare cache purge not working
  Old versions still showing after a purge: browser vs edge cache, cache key mismatches, rule order and cf-cache-status.
• Improve Core Web Vitals with Cloudflare rules
  LCP, INP and CLS: caching, Early Hints and protocol tuning, measured against real field data.

DNS & email deliverability

• Migrating your DNS to Cloudflare without downtime

  Prove your email is legitimate with a safe, progressive DMARC rollout.
