User Centric claimed that sponsored links attracted a greater amount of users' attention in search results returned in Bing than in Google - 42 per cent versus 25 per cent per search.

Related searches in Bing also attracted more attention than in Google - 31 per cent compared to five per cent. Bing displays related searches on the left-hand side of the screen, while Google returns related searches beneath the search results towards the bottom of the page.

User Centric arrived at its findings by tracking search users' eyeballs around web pages in its labs. The eye-tracking generated color-coded heat maps on the screen, with the most intensely viewed areas shown as red - these areas held individual's attention for 4.5 seconds or longer User Centric said.
