 SAN FRANCISCO (AP) — Google already monitors online shopping — and now it's keeping an eye on physical stores to try to sell more digital advertising. 
  
 The internet company said Tuesday that a new tool will track how much money people spend in merchants' brick-and-mortar stores after clicking on their digital ads. 
  
 The analysis will be done by matching the combined ad clicks of people who are logged into Google services with their collective purchases on credit and debit cards. Google says it won't be able to examine the specific items purchased or how much a specific individual spent. 
  
 But even aggregated data can sometimes be converted back to data that can identify individuals, said Larry Ponemon, chairman of the Ponemon Institute privacy research firm. 
  
 MINING CREDIT-CARD DATA 
  
 Google says it has access to roughly 70 percent of U.S. credit and debit card sales through partnerships with other companies that track that data. By matching ad clicks with this data, Google says it can automatically inform merchants when their digital ads translate into sales at a brick-and-mortar store. Previously, if people clicked on an ad without buying anything online, an advertiser might conclude that the ad was a waste of money. 
  
 If the program works, it could help persuade merchants to boost their digital marketing budgets. 
  
 The data add to the digital dossiers that Google has compiled on users of its search engine and other services, including Gmail, YouTube and Android. 
  
 Sridhar Ramaswamy, Google's senior vice president of ads and commerce, said the new tracking system was created in consultation with "incredibly smart people" to ensure it's not invasive. He described the program as "secure and privacy safe." 
  
 But Ponemon said that even if Google has good intentions now, companies and governments in the future might not. 
  
 The kinds of data that Google is collecting also could become an inviting target for hackers, said Miro Copic, a marketing professor at San Diego State University. 
  
 "The privacy implications of this are pretty massive, so Google needs to tread very carefully," Copic said. 
  
 GOOGLE'S OPPORTUNITY 
  
 Google already runs the world's biggest online ad network, one that raked in $79 billion in revenue last year. That puts it in the best position to capture any additional marketing dollars spent on computers and mobile devices. 
  
 The Mountain View, California, company touted the store-sales measurement tool Tuesday in San Francisco at an annual conference it hosts for its advertisers. 
  
 This meeting was an opportunity not only for Google to flaunt its new tools, but to work on regaining ground with advertisers who have recently boycotted YouTube . Major advertisers began pulling back two months ago over concerns that Google hadn't prevented major brand advertising from appearing alongside extremist video clips promoting hate and violence. 
  
 DIGITAL DOSSIERS 
  
 Google already knows what you like based on the searches you make and the videos you watch. Online ads are then targeted to those interests. From there, Google can tell when you click on an ad and if you make an online purchase based on that. 
  
 The new program takes that tracking into physical stores. 
  
 Google says its computers rely primarily on log-in information, such as email addresses, to identify the people clicking on ads. It then matches that data with other identifying information compiled by merchants and the issuers of credit and debit cards to figure out when digital ads contribute to an offline purchase. 
  
 It's all done in a "double-blind" way, Ramaswamy said, meaning the personal information that Google has can't be seen by merchants or its credit and debit card partners. By the same token, Google is blocked from seeing personal information held by its partners. 
  
 When it first described the tracking program to The Associated Press, Google provided an example of how it would be able to identify a specific purchase made in a physical store by a consumer who had clicked on a digital ad run by the merchant. On Tuesday, though, Google executives stressed that it won't be able to peer that deeply into what people are buying. 
  
 Google's tool won't work for cash payments or the 30 percent of U.S. card transactions that Google can't currently access. And this works only for individuals who log in. 
  
 Google gives its users the option to limit the company's tracking and control what types of ads they are shown — although in practice, relatively few users tweak such settings. ||||| Next time you see an ad on Google, the company might be able to tell if you went out and bought it in a brick-and-mortar store. 
  
 A new Google (GOOG) feature can tell when someone who clicked on an ad in search results made a credit or debit card purchase at a corresponding physical store. The tool will give advertisers a better idea of how successful their online ad campaigns are. 
  
 How does Google know if you bought something at Subway or Aldo? It works with the credit and debit card companies to match up in-store purchases with your online identity. The company has partnerships with companies that account for 70% of credit and debit card purchases in the U.S.

 The credit card companies provide Google with encrypted information about purchases, which Google software then compares to Google profiles of people who viewed relevant ads. Google cannot actually see any of the encrypted data, so it does not have access to identifiable payment information, like the person's name or what they bought. 
  
 The matches are tallied up in aggregate to protect privacy. That means Google can tell a restaurant their ads resulted in 1,000 people going there to eat and how much they spent, but not share any personal information about individual diners. 
  
 For all its futuristic investments like self-driving cars, internet-beaming balloons and thermostats, Google is still an advertising company. It relies on ad sales for the majority of its revenue. Last quarter, ads made up $21.4 billion of Alphabet's $24.8 billion in sales. Making the connection between online ads and in-person purchases could be huge for the company, which is competing against companies like Facebook (FB) for the same ad buyers.

 Google is also adding another real-world tool to get more customers into physical stores. It will show information for local stores on YouTube ads, such as hours and driving directions to the nearest store or chain location. In order to know what stores you're close to, YouTube will rely on information from your location history. The company has been using this feature on Search and Maps since 2014. 
  
 Google announced the tools on Tuesday at its annual advertising and marketing conference in San Francisco. The YouTube feature is well timed. Earlier this year, some advertisers pulled out of YouTube ads after they were shown alongside extremist videos. 
  
 If the idea of Google tracking real world purchases, even in aggregate, unsettles you, there are ways to opt out. You can log out of your Google Account before using search, or turn off your search history so that it's not saved. You can also use cash to buy your frosty and fries. 
  
 For the local ad information tool, you can turn off your location history. ||||| Google’s holding its annual conference for marketers today in San Francisco, and to kick it off they’re announcing some new tools advertisers can use. One of them promises to tie your offline credit card data together with all your online viewing to tell advertisers exactly what’s working as they try to target you and your wallet. 
  
 Attribution is important to businesses, because marketing costs money. Businesses are willing to spend some money on advertising and outreach — but only if they see it translate into a return. 
  
 The TL;DR Version Advertisers want to know if their ads work before they spend more money on marketing Google has access to 70% of all credit/debit card transactions in the country Google’s matching that credit card data to your ad viewing history to tell marketers if their ads work You can opt out of some, but not all, of Google’s big wide hyper-targeting net 
  
 That return, for decades, was hard to measure in all but the most vaguely correlative of ways. Did people buy your product after seeing your TV ad? After seeing your billboard? On a whim after seeing neither? Who knows! 
  
 But in the age of highly targeted, algorithmic advertising, the landscape is completely different. The apps on your phone know what you looked at and when, and can tie that in to what you see on other devices you’re also logged into their services on (like your work computer). 
  
 Meanwhile, you’re leaving tracks out in the physical world — not only the location history of your phone, but also the trail of payments you leave behind you if you pay with a credit card, debit card, or app (as millions of us do). 
  
 Put A and B together, and suddenly you have a much clearer picture to share with advertisers: Why yes, John Smith did see four ads for your coffee drink online yesterday, before spending exactly what one of those drinks costs at a location of yours near his office. Congratulations, your ads work; spend more money advertising with us now, please. 
  
 Coordinating all those different online and offline data points into one single person’s profile has basically been the holy grail of advertising for years now. Facebook, the world’s second-biggest advertising company (Google’s largest, and everyone else is a distant third), got there first when it launched Facebook Atlas in 2014. That service let Facebook generate universal cross-platform profiles: Any activity on any device you’ve logged into Facebook on counts as “you,” and can be collated into one profile for measuring advertising efficacy. 
  
 Google also introduced some offline measurements to its online tool suite back in 2014, when it started using phone location data to try to match store visit location data to digital ad views. But a store doesn’t make any money when you simply walk into it; you need to buy something. So Google’s tracking that very granularly now, too. 
  
 “In the coming months, we’ll be rolling out store sales measurement at the device and campaign levels. This will allow you to measure in-store revenue in addition to the store visits delivered by your Search and Shopping ads,” Google explains to advertisers. That’s very literally a collection of spending data matched to the people who spent it, matched in turn to people who saw ads. 
  
 Businesses that collect your email address to track your purchases and send you coupons can import their loyalty program data directly into their Google advertiser account, making it even easier to follow you around everywhere you go. For everyone else, Google says its third-party partnerships capture roughly 70% of all credit and debit card transactions in the U.S. 
  
 The data won’t have your name attached, Google makes sure to point out. It’s anonymized and then hashed over, so what advertisers see is that user 08a862b091c379fe9767615d10873 saw these ten ads in the morning, and spent $27.73 at a certain grocery store that afternoon. 
  
 That said, “anonymity” is pretty much anything but.If anyone’s looking at your digital breadcrumbs, they can be reasonably sure you are you from shockingly little data. Studies have shown that it it only takes three pieces of data to identify you by credit card spending alone, or two to identify you from a social media app. 
  
 On top of that, the larger picture of big data is, frankly, kind of overwhelming. FTC research has found that has found that cross-device tracking is everywhere and poorly disclosed. And finely granular ad targeting can have real harms, from small scale price discrimination to unintentional racial discrimination or even completely illegal racial discrimination that perpetuates housing segregation. 
  
 You have a little more control over how Google uses your data (for now) than over Facebook does, at least. You can visit Google’s advertising and privacy settings to opt out of having some of your activity logged, and to opt out of being shown some ads. But your history of ad viewing is still going to be out there, tied to your credit card spending, without a whole lot you can actually do about it. |||||

Google already tracks what you buy online; it's about to start tracking what you buy offline, too, the AP reports. The tech giant announced Tuesday it will start tracking money spent at merchants' brick-and-mortar stores by people who've clicked on those stores' digital ads. Google has access to about 70% of credit and debit card sales in the US, it explains, via partnerships with other data tracking companies; its new tool will match up those sales with the ad clicks of users logged into Google. Google can then let merchants know how effective their digital ads are at leading not only to online sales, but also to in-person sales, thus possibly convincing companies to increase the money they spend on online ads. Google runs the world's largest digital ad network. The Consumerist explains that location services on your phone could also be helpful in tracking offline purchases, giving this example: "Why yes, John Smith did see four ads for your coffee drink online yesterday, before spending exactly what one of those drinks costs at a location of yours near his office." And, as CNN reports, Google will also start making more of an effort to get people into physical stores by offering up local store information on YouTube ads. Google says its new tracking tool is not invasive and that the company won't have access to the exact amount spent or the particular items purchased by a user, but one privacy expert says it's possible for aggregated data to be used to identify individuals—and another marketing expert says this type of data could be tempting to hackers. "The privacy implications of this are pretty massive, so Google needs to tread very carefully," he says.
