SAN FRANCISCO — Google’s skills in tracking people, figuring out desires, and placing ads revolutionized the world of marketing. Now it is adding even more technology muscle to its ad business.

On Tuesday, Google announced a package of products aimed at helping companies more efficiently figure out what potential customers are interested in and how to sell things to them.

The products, called Analytics 360, are Google’s attempt to surpass efforts by companies like Adobe, Oracle and Salesforce in creating marketing clouds that companies use to collect and manage data about customer behavior. A decade ago this was a haphazard affair for data enthusiasts, but increasingly it is an ordinary part of sales.

For Google, it is the main business. In the fourth quarter of 2015 the company had revenue of $21 billion, $19 billion of which came from advertising. While some of that is from individual ad purchases, an increasing amount comes from comprehensive marketing campaigns by big companies.
