Before people start suggesting this is some anti-American agenda from the EU, keep in mind there are many American companies that have been complaining to the EU such as Yelp and Expedia. They want to stop Google's tying practices such as using their monopoly in search (another thing to keep in mind is that their market share in the EU is something absurd like over 90%) to benefit other products and services. It's not really calling for breaking up the company. Also this is specifically about raising the temperature on the European Commission. Parliament itself doesn't do this.

This is a signal from politicians to the European Commission that they can go hard.
