AEO for container registry platforms: AI search visibility ranking
How AI search engines rank container registry platforms by visibility and citations. 20 brands measured quarterly across Google AI Mode: which brands the AI names in answers, which domains it cites as sources, and how the leaders compare. Container registry platforms used to store, distribute, and govern container images across cloud-native software delivery pipelines. Composite score: 70% visibility (% of AI answers naming the brand) + 30% citation rate (% citing the brand's domain). Full methodology →

When buyers ask AI engines about Container registry platforms, Docker Hub emerges as the leader, named in 50.0% of responses. It is often accompanied by mentions of Harbor and Amazon ECR. This visibility underscores Docker Hub's dominant presence, making it a key consideration for those evaluating options in this area.
The rankings are influenced by the sources AI engines lean on, such as google.com and octopus.com. Many of these are aggregator or review sites that collate information from various vendors, impacting how visibility is distributed across brands. This aggregation means that consistently cited brands likely have broad coverage or engagement online.
For buyers, this page highlights what AI engines prioritize: recent reviews, third-party validation, and topical authority. Consider a brand’s ability to consistently appear across diverse sources, as it's indicative of its credibility and relevance. Brands with strong third-party endorsements may offer more reliable and comprehensive solutions.
At a glance
What we observed in this category
Docker Hub dominates this category with a visibility score of 50.0%, more than double Harbor's 25.0% and four times the 12.5% shared by Amazon ECR, GitHub Container Registry, Azure Container Registry, and Google Artifact Registry. The category average visibility sits at just 6.2%, making Docker Hub's lead particularly pronounced. That gap signals that Google AI Mode has formed a strong default association between the container registry category and Docker Hub, which creates a compounding advantage in answer engine optimisation that other brands will find difficult to close quickly.
A notable divergence between visibility and citation appears across several brands. JFrog Artifactory holds zero visibility yet carries a 25.0% citation rate, matching Harbor and outpacing Amazon ECR and GitHub Container Registry on citations alone. Azure Container Registry and Google Artifact Registry each show 12.5% visibility but 0.0% citations, meaning AI surfaces them by name without treating their domains as trusted sources. This split between being named and being cited represents a meaningful AEO distinction: citation signals deeper source trust, while visibility alone can reflect shallow mention patterns.
Google AI Mode is the top engine for every brand in this dataset, confirming that the entire category's answer engine optimisation performance is concentrated in a single engine. The cited sources anchoring AI responses include google.com, octopus.com, shipyard.build, distr.sh, blog.railway.com, reddit.com, youtube.com, and daily.dev. The presence of community and deployment-focused domains such as Reddit and Octopus alongside first-party sources suggests AI is drawing on practitioner content and third-party tooling blogs rather than vendor documentation alone.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
