Top 1,280 River Keywords
Monthly search volume, CPC, competition and a 12-month trend for 1,280 river keywords, updated October 2026.
River keywords are place names and geography: the world's great rivers, river systems, cruises and the vocabulary of rivers (delta, tributary, basin). Travel and education searches sit side by side.
The list holds 1,280 keywords with a combined 617,485,520 searches a month. The most searched are amazon (414,000,000), bar (16,600,000), flow (11,100,000), river (9,140,000), delta (7,480,000), kayaking (6,120,000), temperature (6,120,000), ford (4,090,000), fords (4,090,000) and fish (2,740,000).
Advertisers pay most for indigenous rights ($15.50 a click), community resilience ($11.40 a click), inundation ($10.71 a click), water trading ($9.67 a click) and world water day ($7.89 a click). 16% 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 1.3x 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.
