Fgrade, unadjusted scale

Annual figures cover the 30 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 28 minutes. A year of estimated search visits to the pages measured ≈ driving a new car 2.9 million km, or the electricity of 230 Dutch homes. What these numbers mean
