Annual figures cover the 29 pages I measured and estimated organic search traffic only, so the real total is higher. Coverage is published so you can judge how representative the number is.

One visit ≈ a 10-watt LED bulb for 33 minutes. A year of estimated search visits to the pages measured ≈ driving a new car 960 km. What these numbers mean
