Google to cut web cookies, ending tracking tool for advertisers

Alphabet Inc’s Google plans to block a common way businesses track online surfers in its Chrome browser, Reuters reported.
Google for enterprise technologyGoogle said its plan, which will be implemented within two years, is to restrict advertising software companies and other organizations from connecting their browser cookies to websites they do not operate, the company said in a blog post on Tuesday.

Apple made a similar move in 2017 in its Safari browser, but Chrome’s global market share is more than three times greater at about 64 percent, according to tracking company Statcounter.

Financial analysts expect minimal effect on Google’s own ad business because it gathers data on users in many other ways.

For nearly three decades, cookies placed by relatively unknown companies on nearly every website have fueled advertising on the internet.

Cookies are a tool within browsers that allow website operators to save data about users, so that for example, they can keep a particular user logged into a website over multiple days.

But cookies also have given obscure software vendors, whose technology is used by website operators, a broad window into which webpages a user is visiting. When shared with advertisers, the data enable predictions about which ads the individual would find relevant.

Users and regulators have questioned how businesses with access to the browsing data store and share them since the advent of the cookie. But over the last three years, data breaches and new privacy laws in California and Europe have prompted major changes at internet businesses.

Google said its restriction would not go into effect until alternatives that Google considers more privacy-preserving are viable. Any major transition in Web technology requires significant investment by website operators, and it remains unclear whether more limited data on users would depress online ad prices.

Justin Schuh, a director for Chrome engineering at Google, said initial feedback to proposals it announced in August “gives us confidence that solutions in this space can work.”
