When buyers ask AI engines about VPN services, NordVPN stands out as the clear leader, being most frequently named with a visibility percentage of 62.5. ExpressVPN and Surfshark are also top brands frequently mentioned. This gives NordVPN a strong presence in discussions, which can be reassuring for potential buyers.
The rankings of VPN services are influenced by data drawn from popular sources like YouTube, which often include video reviews, and websites such as thebestvpn.com and cnet.com, which are known for comprehensive product reviews. Reddit and security.org also play roles, highlighting both user experiences and expert opinions.
For buyers, this list offers insight into what AI engines value when recommending VPN services. They prioritize brands with strong third-party validation and recent reviews from trusted sources. Consider looking at the reviews and content from these top-cited sites to make a well-informed decision based on up-to-date and authoritative sources.
At a glance
What we observed in this category
NordVPN leads the VPN services AI visibility landscape with a composite score of 55.0 and visibility of 62.5%, well above the category average of 10.6%. The gap to rank two is meaningful: ExpressVPN and Surfshark both sit at 50.0% visibility but score only 38.8 composite, a 16-point deficit. Below rank four, visibility collapses sharply, with Mullvad at 12.5% and six brands including IPVanish and Private Internet Access registering zero visibility, showing the category is effectively a three-brand AI conversation.
A clear divergence exists between which brands are named and which are cited. CyberGhost, Norton Secure VPN, and Windscribe each hold a 12.5% citation rate despite 0.0% visibility, meaning AI responses reference their domains without featuring them prominently in answers. ExpressVPN shows the opposite tension: visibility doubled from 25.0% to 50.0% in the latest period, yet its citation rate held flat at 12.5%, suggesting it is named frequently but not treated as a trusted source anchor.
Google AI Mode is the dominant engine across all 20 brands in this dataset, with no brand recording a top engine other than Google AI Mode. Among cited sources, youtube.com, reddit.com, cnet.com, and pcmag.com appear alongside specialist sites thebestvpn.com, security.org, and pcworld.com. NordVPN is the only brand whose own domain (nordvpn.com) appears in the top cited sources list, indicating AI anchors on third-party review and community content rather than brand-owned pages for most VPN queries.

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 →
