Google has managed to add to its already dominant search market share, as rival Yahoo slid slightly last month.
In the US in March, Google held 63.7 per cent of the market, up from 63.3 per cent in February, according to stats from comScore. Yahoo slipped slightly from 20.6 per cent to 20.5 per cent.
Microsoft held just 8.3 per cent, followed by Ask at 3.8 per cent and AOL at 3.7 per cent.
Americans used such search engines 14.3 billion times in March, up nine per cent on February at least partially explained by the shorter month.
Google might be leading in search, but its move into other web areas has created privacy and copyright concerns.
