Cookies can be used to record various kinds of data about users including: what you do on the site, whereabouts in the world you are, what device you are using and where you go online afterwards. Google has begun testing changes to the way companies are able to track users online. A new feature in the Chrome browser disables third-party cookies – small files stored on your device to collect analytic data, personalise online ads and monitor browsing. Google describes the changes as a test, with plans for a full rollout to eliminate cookies later this year. Will this affect Google marketing revenue ?
