At a glance
What we observed in this category
Plex leads the manufacturing execution systems category with a visibility score of 50.0%, more than double the 25.0% held by second-place Siemens Opcenter and Tulip. The category average visibility sits at just 6.9%, making Plex's position a significant outlier rather than a marginal lead. This gap suggests AI responses in this category are not distributing attention evenly across vendors, and brands outside the top three receive minimal or zero unprompted mentions in Google AI Mode responses.
A clear divergence exists between which brands get named and which get cited. Plex has 50.0% visibility but 0.0% citation, meaning AI responses mention it without linking to its domain. SAP Digital Manufacturing shows the reverse pattern, with only 12.5% visibility but 25.0% citation, and Critical Manufacturing achieves 25.0% citation despite 0.0% visibility. This split indicates that being named in AI narratives and being used as a source reference are two distinct and poorly correlated signals in this category.
Google AI Mode is the dominant engine across all ten tracked brands, with no alternative engine appearing as a top performer for any brand. The top cited external sources include gartner.com, youtube.com, softwarereviews.com, and abiresearch.com, pointing to analyst reports, review platforms, and video content as the primary anchors for AI-generated responses. Niche sources such as ifactoryapp.com, averroes.ai, reliamag.com, and harmoni.io also appear, suggesting the AI draws on a broader, less predictable source pool than major analyst sites 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 →
