Top 813 Arduino Keywords: Search Volume, CPC and Trends (October 2026)

Arduino keywords are maker and education terms: boards, sensors, projects, code examples and kits. Volume is driven by students and hobbyists; the CPCs by component sellers and course providers.

The list holds 813 keywords with a combined 3,426,810 searches a month. The most searched are arduino (1,000,000), arduino ide (450,000), arduino uno (368,000), arduino projects (246,000), arduino nano (135,000), arduino uno r3 (60,500), arduino mega (40,500), arduino cloud (33,100), arduino kits (33,100) and arduino starter kit (33,100).

Advertisers pay most for arduino cli ($1.34 a click), arduino command line ($1.34 a click), arduino iot cloud ($0.55 a click) and arduino cloud ($0.52 a click). 0% of the keywords in the list cost $1 or more a click, which marks the commercial end of the niche.

Demand is steady through the year: across the list, the busiest and quietest months are within 1.4x of each other. The trend column shows each keyword's own twelve months.

Volumes are global monthly averages from Google; CPC is the top-of-page bid in US dollars; competition runs from 0 (few advertisers) to 1 (many). Last refreshed October 2026. For any other keyword, the free search volume checker gives the same numbers, and the Keywords Everywhere extension shows them inside Google as you search.
