CTR Performance Comparison (October vs September 2025)
A notable change between the two months warrants further breakdown.
As the volume is low to begin with, we'll ignore statistics for DoK, Edge & IT, as well as certification-based content.
Here are the key changes worth noting:
- CTR for Data on Kubernetes decreased by 5.40pp, but rose by 2.50pp for Infrastructure and 1.76pp for Networking. The average CTR for the two months differed by just 0.14 percentage points, despite apparent variance.
- Interestingly, Observability which was a trending topic for September, suffered a 1.90pp loss in CTR, while Security and Development gained it by 0.70-0.80pp month-on-month.
Account Performance Analysis
We'll discuss the key trends we've observed in the performance of our accounts.
The dominance of Architectural content in the Learnkube media universe.
Kube Architect, focusing on development, software architecture, and software development lifecycle, has shown high demand for this content type in recent months.
Kube Architect's average impressions per post have consistently increased, while maintaining an impressive volume of between 560k and 570k impressions per month.
Month-on-month, Efficiency for Kube Architect has increased by 4%.
The Kubernetes community has caught on with the Podcast fever.
KubeFM, our podcast, continues to gain audience, highlighting demand for podcast content.
While month-on-month KubeFM's total volume (of impressions) has increased by 4.5%, it has risen by 20% when compared to the numbers back in July 2025.
Top Content Performance Analysis
Highest Volume Content (>15k impressions)
- The top content in October 2025 was a Golang Tool - Kor overview (for unused Kubernetes resources), earning 77,510 impressions.
- Next was Kite, a lightweight Kubernetes dashboard, with 42,474 impressions, followed by FaaS (22,934), a deployment tool, and K3k (22,081), a multitenancy solution.
All four top pieces, with the highest volume, were tool overviews, totaling 164,999 impressions. **
While these content pieces had the most impressions, the CTR hierarchy was a little different.
Highest CTR Content (>7.5%)
| Content | CTR | Impressions | Clicks |
|---|---|---|---|
| Kubernetes observability from day one - mixins on Grafana, mimir and alloy | 13.38% | 2003 | 268 |

| Non-HA Kubernetes Gotchas: Downtime and Autoscaling Pitfalls with Single Replica Workloads | 7.01% | 1807 | 123 |
It becomes fascinating when we categorize the highest CTR content by category and subcategories._
The key takeaways here are:
- Tool overviews = CTR magnets. The best performing category for the second month running.
- Case studies and Walkthroughs come in with second-best CTR numbers. Highlighting why a plain tutorial isn't enough anymore unless you bring in a personal perspective/opinion to the content.
- Since the announcement content was an official Kubernetes release, it received such a high CTR.
Key Trends and Insights
October 2025 confirms demand for Data on Kubernetes (DoK) content
A topic curiosity that intrigued in September has now been confirmed as a trend with October data.
Most efficient topic for the second month running, while the total impressions have increased by almost 40% month-on-month.
The Cloud-native/Kubernetes community has caught the Podcast fever
While hands-on tutorials, walkthroughs, and tool overviews make for good reads, the audience yearns for Podcast videos - essentially not full podcast episodes, but shorter clips that articulate an opinion. A detailed review of podcast content will be included in our November 2025 report.
KubeFM, our podcasting brand, has now made 100k+ impressions for the second consecutive month, indicating even better numbers in the coming months.
Observability content = High CTR
While Observability content had the second-highest CTR (5.50%) in September, it has now taken the number-one spot (3.77%) in October, with a volume of 66,150 impressions.
As we increase the frequency of content for this topic, we'll understand if it can translate into a high-volume and high-efficiency topic.
Resource Optimization and Configuration Management are almost evergreen topics
For every month over the past six months, either one of these topics has ranked in the top two on the most efficient list. Highlighting the consistent demand for the topic content.
If we average the impressions for these topics in the last six months, it comes out to be an impressive 164,276 for Resource Optimization and 145,209 for Configuration Management.
