Technology brands and tech-adjacent websites dominate Arduino's nearest audiences, with no single neighbor pulling far ahead of the rest — the top 10 span a tight 0.85 to 0.82 range.
The shape is flat: DigitalOcean leads at 0.85, followed closely by MacRumors.com at 0.84, Adafruit Industries at 0.84, MongoDB at 0.84, and GitHub at 0.83. Six of the top 10 neighbors carry the Technology subcategory (Brands), while the remaining four are Websites — specifically MacRumors.com, Slashdot, Macworld, and The Hacker News. The one outlier in the set is Curiosity Rover (0.83), classified under Miscellaneous > Technology — a research and exploration entity whose audience nonetheless maps closely onto this same profile. No celebrities, no retail, no entertainment properties appear in the top 10; the cluster is almost entirely developer tools, cloud infrastructure, and tech-news destinations.
What stands out is how tightly the neighbor set stays within a single professional-technical lane. The spread from first to tenth is only 0.03 similarity points, meaning no single neighbor is a dramatically stronger match than any other — the audience shape is consistent and cohesive across the whole cluster.
This flat, tech-dense pattern suggests Arduino's audience is drawn from a well-defined technical community whose attention is distributed evenly across developer platforms, open-source infrastructure, and Apple-ecosystem news rather than concentrated around any one hub.
