A typical website in the UK receives 40% of it's traffic from Google properties

The quote comes in an article about twitter:
"During March, 24.3% of Twitter’s UK Internet traffic came from Google properties, whereas for Facebook the figure was 34.6%. A typical website in the UK receives 39.9% of it traffic from Google properties [my emphasis], so Twitter is less reliant on the search giant for traffic than both Facebook and the UK average. However, Twitter’s largest source of UK Internet traffic is actually Facebook (which accounted for 18.2% of its traffic in March, compared to 15.4% from Google UK), presumably a result of the integration between Twitter updates and Facebook status feeds."
