Top 1,136 Chemistry Keywords
Monthly search volume, CPC, competition and a 12-month trend for 1,136 chemistry keywords, updated October 2026.
Chemistry keywords are study terms: the periodic table, reactions, equations, named compounds and exam topics. The searches peak with the school year; tutoring and course providers are the few advertisers.
The list holds 1,136 keywords with a combined 129,767,110 searches a month. The most searched are gases (30,400,000), periodic table (9,140,000), temperature (6,120,000), mole (2,240,000), ph (2,240,000), glass (1,830,000), alcohol (1,500,000), proton (1,500,000), bases (1,220,000) and batteries (1,220,000).
Advertisers pay most for chemical weapons convention ($5.27 a click), lipidomics ($3.83 a click), ocean acidification ($3.52 a click), inductive effect ($3.38 a click) and leaving group ($3.19 a click). 15% 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 1.2x 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.
