How to know if self-regulation is working: Feature article in Adotas

September 27, 2010

Some key elements are now in place for the self-regulatory framework to ensure privacy and choice in ad tracking. Today in Adotas I’m suggesting three key things that will indicate initial success for the new system:

  1. The consumer experience is great;
  2. Failures are visible; and
  3. Outliers are shunned.

Google takes out the trash? Not so much.

September 4, 2010

Those keenly interested in Google’s every move on privacy didn’t miss the fact that Google chose this Friday-before-a-long-weekend to announce a revision to their master privacy policy, which will be effective on October 3. (Marked copy is at the end of this post.)

For fans of the West Wing, you might be thinking Google must be “taking out the trash,” which refers to the strategy of announcing bad news on Friday afternoons when fewer folks are tuned in. In fact, there’s actually very little in here of interest.

When I first saw the announcement, I hoped there might be greater clarity on Google’s data retention policy, but got no love on that count. In fact, there’s no mention of any changes coming in the separate advertising-related privacy policies.

At the risk of revealing my wonkishness, one passage did catch my eye; note the addition of the last three words in this paragraph:

Google also uses cookies in its advertising services to help advertisers and publishers serve and manage ads across the web and on Google.

I wasn’t aware that third-party ads were being served in Google, but perhaps with the advent of the Google’s ad exchange (see prior post), this is changing.

See anything else interesting in here? Let me know.

AddThis transitions to behavioral advertising, ignoring key privacy questions

August 11, 2010

Last week AddThis announced that data collected through their sharing widget, installed on 1.5 million websites, will now be used for behavioral advertising. According to the announcement, anonymous profile information for over 200 million users, including the pages they have visited on AddThis publisher sites, is now available to other ad delivery companies in real time bidding.

The new AddThis program is similar to Google’s transition of AdSense into an ad exchange platform (see prior posts). In both cases, tags placed on publisher sites for one purpose are now being used for different and more extensive purposes. And in both cases the companies should clarify answers to some important privacy questions.

Publisher Notice

Shouldn’t publishers be made aware of the change in how their users’ data will be handled, and provided with an opportunity to opt-out? Is it fair to assume that all sites with the widget already installed — including hospitals, schools, church groups, and government agencies with no other advertising — would choose the AddThis widget if they were aware that their user behavioral data will be sold?

For publishers signing up today, there’s no reference to behavioral data collection in the signup process for the AddThis widget. Is this deceptive?

Consumer Notice

Will the AddThis widget include a notice to consumers that tracking information is being collected on each page that serves the widget, regardless of whether the consumer interacts with it? (This kind of notice is required under the IAB’s guidelines and could be provided with something akin to the power “i”.)

Will AddThis also ensure that when the data are used to display an ad, the consumer will be notified that AddThis was the source and provide an opt-out?

Are AddThis publishers required to amend their own consumer privacy policies to provide notice of AddThis data collection, as is standard practice for compliant ad networks?

Will consumers be able to see what’s in their own AddThis profile, as they can on Google, Yahoo! and leading ad networks?

NAI Compliance

Neither AddThis nor its parent Clearspring is listed as a member of the Network Advertising Initiative, the industry organization charged with defining privacy standards and providing oversight for behavioral advertising.

The AddThis announcement says that the company “complies with the Network Advertising Initiative standards.” What does this mean, given that AddThis is not subject to NAI compliance reviews; they do not appear to follow the NAI’s requirement that publishers pass through disclosure in their privacy policies; and they lack NAI-required privacy disclosure as to data retention?

Why wasn’t NAI membership considered a prerequisite to launching the new program?

Conclusion

Hopefully AddThis will move quickly to remedy the privacy shortcomings in their new program. How they approach this will tell us not only about their own commitment to privacy and self-regulation, but also the commitment of any partners and advertising customers who continue to participate.

A Self-Regulatory Moment

March 26, 2010

An earlier post about Google’s new “certified ad network” program raised the question of whether websites should disclose to consumers which third-party networks may have access to user data through AdSense. Google’s program allows certified networks to use previously collected behavioral data to target ads served through AdSense, but prohibits (by contract) the collection of new data for future use. Based on this distinction, Google does not provide consumers with any specific notice-and-choice as to certified ad networks.

Lurking here is a fundamental question about ad-targeting disclosure: is it good enough to provide notice and choice only when behavioral data are being collected, or must you also provide it when being used?

Google’s approach seems founded on a literal reading the FTC’s 2009 Staff Report on Behavioral Advertising (see page 52), which by its terms speaks only of notice-and-choice on every website “where data is collected.” The NAI’s self-regulatory principles use similar language. But neither the FTC nor the NAI discussed “use” versus “collection,” the involvement of multiple companies in delivery of a single ad, nor a notion that disclosure standards might differ in those cases.

There are good reasons to conclude that consumers deserve notice-and-choice both at the point of collection and the point of use of behavioral data.

  1. The serving of a targeted ad will be the moment of recognition for many consumers; the very point at which they want to understand and exercise their choices. If they can’t easily identify the company serving the ad based on prior collected behavior, they have no way to prevent it from continuing.
  2. With visibility as to which third-parties have access to data, consumers can make their own decision about whether to rely on Google’s contractual rules about how it may be used. Google’s approach is a black box for consumers; they receive no direct assurance from the certified ad network about their practices, nor any assurance that Google will monitor or enforce the contractual prohibitions on their behalf.

In plain terms, Google says to the consumer: If you don’t opt-out when information is first being collected about you, you lose the practical ability to do so when it is used to show you targeted ads. Google’s own opt-out program does not appear to remove the user from receiving behaviorally targeted ads from non-Google networks through AdSense.

Did the FTC Staff intend this outcome? There’s nothing in the rest of the Staff’s discussion to indicate that they meant to exclude the use-only situation from enhanced disclosure.  Indeed, in distinguishing first-party from third-party data collection, the Staff said:

By contrast, when behavioral advertising involves the sharing of data with ad networks or other third parties, the consumer may not understand why he has received ads from unknown marketers based on his activities at an assortment of previously visited websites. Moreover, he may not know whom to contact to register his concerns or how to avoid the practice.

In the same statement, the FTC Staff spoke to this kind of novel situation when they said, “Where the data collection occurs outside of the traditional context, companies should develop alternative methods of disclosure and consumer choices that meet the [transparency] standards described above …”

The IAB-led coalition has adopted principles that require notice-and-choice “when data is collected from or used on a Web site for Online Behavioral Advertising purposes …” (page 17) The IAB’s overall approach to disclosure is premised on embedding notice into ad-delivery, which like the FTC explained, satisfies a consumer curious about why they saw a particular ad. This is true whether or not data are also being collected for future targeting.

“Fourth-party” ad delivery of the sort now available in AdSense is increasingly common, and Google’s precedent may end up as an industry standard. If enhanced disclosure only applies at the point of collection of behavioral data, and not at the point of use, that should be based on a thoughtful discussion of the consumer impact, rather than a narrow reading — and most likely a mis-reading — of FTC staff guidance.

This will be an important test of the industry’s self-regulatory framework. Google is an NAI member (as are several certified ad networks), and this question involves interpretation of NAI guidelines. One way or another, the NAI must pass judgment on the point, and in doing so will demonstrate whether consumers (and the FTC) can count on an effective self-regulatory effort for behavioral advertising.

AdSense Opens Up to “Certified Ad Networks”: Three Questions for Google

March 22, 2010

Google made it official last week: Any site in the vast AdSense network may now carry ads placed by third-party ad companies, which Google calls “certified ad networks.” This is an important privacy development, as it means that more than 80 new companies may now use or collect user behavioral information through Google ad tags that are already installed on millions of web pages. (To learn how this works, see the video embedded at the end of this post.)

Because these companies are hungry for access to the AdSense network, Google’s certification requirements may have more immediate impact on prevailing ad-industry privacy practices than any new regulation or industry initiative. By setting and enforcing standards on participating networks and AdSense publishers, Google has the opportunity to catalyze a truly effective self-regulatory system for interest-based advertising.

To do so, Google should answer three key questions:

1. How does Google confirm compliance with certification standards?

Google’s policies do not require that certified networks be members of the Network Advertising Initiative, the group of leading ad companies (including Google) that sets standards and provides compliance reviews. But Google does require certified ad networks to abide by the NAI’s 2008 Guidelines. These rules require a consumer-facing explanation of what kind of information is gathered and how it is used, as well as:

  • Disclosure of how long consumer data is retained;
  • A consumer opt-out process (such as an opt-out cookie); and
  • Assurance that sensitive behavior (i.e. health, personal finance) will not be used for ad targeting without prior user consent.

A review of selected privacy policies from certified ad networks shows that quite a few do not meet these requirements (as of 3/19/10). Some examples (with links to the PrivacyChoice Index):

Google also should clarify these technical and operational points:

  • Do certified ad networks have access to behavioral data, even if they have agreed not to collect such information when serving ads through AdSense?
  • Does the network see the site or page visited, an IP address or the network’s cookie? If so, does each certified ad network need to engineer their backend systems to segregate AdSense data from data gathered elsewhere?
  • Will compliance be subject to review by Google personnel or any independent organization?

2. Will Google provide AdSense publishers with privacy-related information about certified networks, in order to enable them to make better decisions?

Google puts AdSense publishers in control by allowing them to turn off certified networks individually or entirely, but does not yet provide any privacy-related information to inform those decisions. Some AdSense publishers might want to allow only companies that are subject to oversight through the NAI; others might want to review retention or other specific privacy policies.

Google could improve website decision-making by showing publishers information about the privacy practices and oversight for each certified ad network. Website operators ultimately must be accountable to their own users for the practices of companies who have access to their user information. Google can make it easier for publishers to make good decisions, and thereby support higher standards across the industry.

3. Will Google provide AdSense publishers with a way to disclose third-party networks and their privacy policies to consumers visiting their sites?

Google already requires AdSense publishers to disclose that Google itself may collect or use behavioral information through AdSense, and requires sites to link to Google’s privacy policy and consumer opt-out choices. Under the NAI guidelines, each certified ad network engaged in behavioral advertising also has the same obligation when serving ads via AdSense. The practical problem is that AdSense publishers may not know which certified networks will be serving ads on their pages, since the ads come through pre-existing tags. The list is also subject to change, which makes disclosure a continuing headache for websites. Of course, just providing one big list of 80+ networks would not constitute meaningful disclosure.

For good reason, both the NAI Guidelines and those adopted by the IAB-led coalition require such disclosure not only when behavioral data are being collected, but also when behavioral data are being used to target ads (which is when the consumer may be most curious). This means that even if certified networks follow the rules against collecting behavioral information through AdSense, if they use other behavioral data to target ads, then enhanced disclosure is required on the website or page where the ad appears.

The process of providing this disclosure can be automated. The free PrivacyWidget service demonstrates one method to automatically present the right list of ad networks (and related opt-outs) on the fly, with minimal publisher effort.

Conclusion

When Google launched interest-based advertising across AdSense last year, their transparent consumer privacy approach raised the bar for other ad networks. Google’s launch of certified ad networks in AdSense should reflect the same commitment. By following through on the questions outlined here, Google can seize the opportunity to set best practices for the industry and accelerate consumer understanding (and informed acceptance) of interest-based advertising.

PrivacyWidgets as a platform for value-exchange

January 18, 2010

As mentioned in the release notes for the PrivacyWidget and earlier posts, PrivacyWidgets can provide a platform for the value-exchange between consumers and advertisers using behavioral advertising. In this relationship, the consumer exchanges information about themselves and their interests for more relevant advertising and content.

Some ad-delivery companies are already investing in making the value-exchange more transparent for users, by showing them information about the specific interests and preferences that have been stored about them. At least seven companies already do this: BizoBlueKaieXelateGoogleRubicon ProjectSafecount and Yahoo!

These companies are betting that, by and large, consumers will appreciate more relevant advertising and can be made comfortable with any privacy impact. They’re giving this substance by reading back something about what they know about the consumer, and inviting the consumer to engage with a process to share even more about their interests.

PrivacyWidgets facilitate this transparency. As a simple start, we had added links within the PrivacyWidget to take the user directly to their personal preference information for those companies that make it available. Check out the Sample PrivacyWidget on our site to see some examples.

This is also good for websites, who choose their ad delivery partners and provide the context for the exchange in value: ad-supported content and services. Consumers who will share more about their interests will provide more advertising value. So PrivacyWidgets offer more than just an easy way to comply with disclosure requirements; over time they can drive engagement and higher ad value. For the consumer, this virtuous circle leads to more and better free content.

Google’s Teracent: The worst consumer opt-out? (updated)

January 10, 2010

UPDATE 1-18-10: Some rapid progress on improvements: There is now an opt-out link on Teracent’s homepage and the CAPTCHA requirement has been removed. Hopefully improvements are also in the works to make the opt-out cookies unique and longer-lived (although just as likely, you might expect Teracent’s entire process to be assimilated into Google’s consumer disclosures and opt-out interface). In the mean time, here’s Teracent’s entry in the PrivacyChoice Index (still showing no opt-out available, given the remaining uncertainties).

In November of last year, Google announced the acquisition of Teracent, a company specializing in dynamic ad creative that is customized on the fly based on factors like the user’s interests and location. A review of Teracent’s consumer privacy experience shows that Google has much work to do in order to bring it up to industry norms. Unfortunately, it also provides a reminder of the challenges to self-regulation for ad-targeting.

Starting with disclosure, the Teracent privacy policy includes the kind of statement that confounds privacy advocates (for good reason):

“We retain the Non-[Personally Identifiable Information] collected via our Technology for up to 6 months in order to ensure that our Technology is functioning properly. After 6 months, we render this information anonymous and store it for up to three years.”

But wait, if the information you collect is “Non-Personally Identifiable” then why would you need to render it “anonymous” after six months? Isn’t it already anonymous?

Of course, they probably mean that after six months they will disassociate individual log entries from IP addresses, but can a consumer possibly understand what this means?

There’s even more work to do on Teracent’s opt-out process, which doesn’t even come close to best practices (see our handy guide to those):

1. The process is not easy to find because it’s not linked from Teracent’s homepage. An interested consumer needs to click the “About” link from the homepage to then see anything about privacy or an opt-out.

2. The opt-out cookies themselves store unique strings (destroying any semblance of anonymity) and are not named in a way to be identified by the user as an opt-out cookie. (The vast majority of networks include the phrase “opt out” in the cookie name or text to make this clear.) Also Teracent appears to use three different domains in the opt-out process (teracent.net, smtad.net, ytsa.net) but you can’t tell if all three are necessary for the opt-out to be effective. If all three aren’t necessary, the ones that aren’t shouldn’t even be written as part of the process.

3. The opt-out cookies have a six-month lifespan, far short of the five-year minimum now required by the NAI.

4. This is really unusual: the user has to complete a CAPTCHA in order to get the opt-out cookie(s). And it’s a fussy one, at least in my experience. I’m not sure I’ve seen an opt-out process that is less consumer friendly.

No doubt Google is working to assimilate Teracent into its own (much better) consumer privacy practices. But Teracent’s shortcomings provide a good reminder of the chasm in quality between the best and worst consumer privacy practices of ad-targeting companies. Until websites and advertisers start to attend to these matters in their own choices, this disparity in commitment to best practices will remain a central challenge to effective self-regulation.

Doubleclick’s Flash cookies

October 25, 2009

Since the next version of the privacychoice opt-out tool will incorporate integrated control of Flash cookies, we’ve developed internal tools to start monitoring the incidence of use of Flash cookies by tracking companies. It’s not news that use of Flash cookies has been widely embraced by ad networks; what is surprising is how few of them explain this in their privacy disclosures, or provide any guidance on how to delete or control them.

The most notable example of missing Flash-cookie disclosure comes from the biggest dog of all: Google’s DoubleClick subsidiary. We’re seeing their Flash cookie, googleads.g.doubleclick.net, on multiple test machines, which raises questions:

  1. Is DoubleClick’s Flash cookie used to gather interest information? This is not confirmed one way or another in the privacy policy, but should be. (In fact, a search of DoubleClick’s site reveals no mention of Flash cookies.)
  2. If I expressly opt out using the regular DoubleClick browser cookie, and then that opt-out cookie is deleted for any reason, does DoubleClick reconnect my profile with the surviving Flash cookie? Why doesn’t Google just delete the Flash cookie as part of the normal opt-out process?
  3. Better yet, if Google is using Flash cookies to enhance the ad serving experience, why not set the user’s opt-out preference with a durable Flash cookie?

My guess is that DoubleClick’s Flash cookies are not used for interest gathering or ad targeting, but in the absence of a clear statement as to how they are used, consumers are left to wonder.

AdSense opens up and privacy disclosure gets more complicated

August 27, 2009

According to Paid Content, Google’s AdSense network will soon allow many other third-party ad networks to serve advertising via the AdSense code already embedded on millions of websites. This is significant from a privacy point of view, to the extent that it provides many smaller ad networks with access to a much wider set of websites, complicating privacy and opt-out disclosures.

googleadsenseGoogle will make the determination as to whether a third-party ad network qualifies to participate, and according to the program rules, this includes a review of their privacy practices. When it comes to user targeting, here’s how Google explains the requirements in an FAQ for third-party ad networks:

You may use cookies for reporting purposes and to target ads, provided that the data you use was collected in accordance with industry standards:

Where there is a conflict between the NAI and IAB UK policies, the more stringent policy applies. Google determines at its own discretion whether or not you are compliant with these standards.

In particular, the certification process requires you to have the following:

  • A descriptive privacy policy on your site
  • A prominent link to opt-out from the privacy policy
  • No PII used in the creation of segments
  • No sensitive segments or segments targeted at children under 13 years of age
  • No packet sniffing in the collection of behavioral data

There’s no mention of the new self-regulatory principles, which are more specific about disclosure and require individual websites to disclose specific ad networks that use or collect behavioral data on their site (if such disclosure is not present in the ads themselves). Google does not seem to be requiring that a participating AdSense website provide such disclosure; the privacy statement and opt-out presentation applies only to the ad network’s own website.

The AdSense policies draw a distinction between collection and use of behavioral information in this program — third-party networks may use behavioral information they have gathered elsewhere to serve the ad, but may not collect information for behavioral purposes in the course of serving it. As Google explains it to the ad network:

You may use a cookie, web beacon, or other tracking mechanism to collect anonymous traffic data for purposes of aggregated reach, frequency and/or conversion reporting. Collecting impression-level data via cookies or other mechanisms for purposes of subsequent re-targeting, interest category categorization, or syndication to other parties on AdSense inventory is prohibited. (This restriction does not apply to click- or conversion-level data.)

Google does not explain here if or how these distinctions will be enforced. The same information is available to the ad network in either case, so to confirm compliance with this rule would require some kind of back-end audit of the network’s practices.

We will be watching AdSense sites closely as new networks start to flow through Google’s widely distributed Javascript. The privacychoice platform looks beyond the Javascript itself to see which servers are actually serving ads on a page through that code, so our Network Privacy Profiles will provide an accurate picture of the privacy policies in play for any AdSense website that opens up to third-party ads. For an AdSense website publisher committed to complete privacy disclosure and choice, our system should provide a simple solution.
