Google's parent company, Alphabet, saw its shares drop in after hours trading after the internet giant missed revenue forecasts.
Alphabet, which also owns YouTube, reported $36.3bn (£28bn) in sales for the first quarter, below expectations of $37.33bn.
Profits also fell during the three months to 31 March.
It was impacted by a fine from the European Commission for blocking rival online search advertisers.
Shares in Alphabet fell by nearly 5%.
