When buyers inquire about Knowledge graph platforms, AI engines frequently highlight Neo4j as the top choice. Leading with 50.0% visibility, Neo4j stands out due to its strong presence. Other notable mentions include Stardog and Amazon Neptune, demonstrating these brands' competitive stance in the field.
The rankings reflect reliance on widely cited sources such as google.com and ovaledge.com, indicating that AI engines trust large aggregators and authoritative domains. The prominence of these sources suggests that platforms with substantial third-party validation enjoy enhanced visibility.
For buyers, this emphasizes the importance of selecting a brand with strong AI recognition. When choosing from the list, consider how often a platform is reviewed or discussed by leading sites. AI engines favor brands with recent reviews, authoritative third-party validation, and expertise in specific subcategories.
At a glance
What we observed in this category
Neo4j holds the clear lead in this category with a composite score of 50.0, which is more than double Stardog's 26.2 and nearly three times Amazon Neptune's 17.5. The category average visibility sits at just 7.6%, meaning Neo4j's 50.0% visibility figure represents a gap that most competitors cannot close through incremental improvements alone. Eight of the 18 tracked brands register zero composite score, which signals that AI Mode is consolidating answers around a very small set of recognised names.
Stardog illustrates a meaningful divergence between visibility and citation performance. It appears in 37.5% of responses, placing it second for visibility, yet its citation rate is 0.0%. Neo4j, by contrast, matches its visibility score with an equal citation rate of 50.0%, and Memgraph also maintains parity at 12.5% each. This pattern suggests AI Mode names Stardog as a relevant brand but does not anchor answers to its domain content, a distinction that matters significantly for AEO because citation drives referral intent.
Google AI Mode is the sole engine driving all rankings in this dataset, and the top cited external sources include google.com, ovaledge.com, youtube.com, and neo4j.com directly. The presence of neo4j.com as a cited source reinforces why Neo4j achieves citation parity with its visibility. Third-party comparison and market-research domains such as ovaledge.com, digetiers.com, devopsschool.com, and fortunebusinessinsights.com also appear in the citation list, indicating that AI Mode draws on independent review and analyst content rather than vendor pages 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 →
