In response to unexpected SEO traffic loss caused by misidentified crawl activity, we built a custom Googlebot exemption mechanism into our CDN. The result: full indexing coverage, zero compromise in bot protection, and a 34% increase in organic traffic.
Industry
Funtech
Our client is a mid-size Video Streaming platform. It operates in a content-heavy, high-traffic environment where SEO performance directly impacts growth. Their infrastructure includes a security layer with advanced anti-bot protections – optimized for detecting and blocking malicious actors like scrapers, DDoS attackers, and credential stuffers.
Challenge
During Google’s algorithm updates, Googlebot often ramps up crawl activity to re-index affected sites. Our client’s anti-hotlink system was tuned to block requests exceeding a fixed rate per IP, a rule that typically stops botnet traffic and abuse.
However, this system did not distinguish between Googlebot and harmful bots. When Googlebot’s frequency exceeded the threshold, the crawler was blocked or throttled, resulting in:
- Delayed or partial indexing
- Reduced search visibility
- A sudden drop in organic traffic
Since Google does not announce crawl-rate changes ahead of time, when the server saw an unexpected increase in bot traffic, it treated it as an attack.

Solution
After analyzing the clients’ issue, we decided to develop smart exemptions and rule tuning features to restore healthy indexing for the client. We designed and implemented a targeted functionality within the CDN that allowed Googlebot to bypass rate limits while preserving strong anti-bot protections elsewhere.
Our approach included:
1. Googlebot whitelisting logic
We engineered a verification mechanism that allows us to reliably identify Googlebot traffic – accurately distinguishing genuine crawlers from impersonators.
2. Exemption from rate-limiting
Once verified, Googlebot was granted a “trusted crawler” status. This bypassed all frequency thresholds and IP-based blocking rules, allowing it to crawl freely regardless of volume.
3. Platform-wide configurability
We extended this solution beyond a single client, transforming a specific issue into a platform-wide enhancement. We began by analyzing the client’s problem and manually adjusting settings to ensure legitimate crawlers were properly recognized. Then, we updated the protection functionality across the entire platform and added a toggle for Googlebot (and other known crawlers) in all our clients’ dashboards. Since then, the feature enables our CDN users to balance tight security and search visibility in a controlled, predictable manner.

Results
The initial implementation resolved the client’s indexing delays and resulted in a significant increase in organic traffic. Googlebot resumed high-frequency crawling without triggering false positives.
Following this success, we rolled out the solution across our broader client base, leading to several key outcomes:
- 100% indexing coverage during subsequent Google updates
- Sizeable SEO traffic gains
- No compromise in anti-DDoS or malicious bot detection
- Platform-wide adoption of trusted bot exemptions
- Improved crawl health scores across multiple ecosystems
Clients appreciated the ability to fine-tune bot access directly in their CDN settings. For high-traffic, SEO-sensitive businesses, this added control meant:
- Consistent content discovery
- Lower SEO risk during Google rollouts
- Faster reaction time to indexing anomalies
What began as an emergency fix became a long-term feature. This not only restored search visibility for one client, but helped others facing the same challenge during algorithm updates.
