In 2020, Google began phasing in a privacy feature called "Consent Mode," which changes the way you collect ads tracking data and your analytics. The new feature allows you to modify tracking tags based on whether your site's users permit you to track them.
Right now, the Consent Mode framework is compatible with both opt-in and opt-out users. Opt-in users have explicitly said yes to your tracking efforts while opt-out users are tracked by default, but who have the right to say "no."
Google's Consent Mode is still in beta, which means it's essentially in early or limited release. It's an optional feature that allows you to manage the consent preferences of your website's visitors when interacting with Google-owned properties, such as Google Ads and Google Analytics.
It's brand new, still in a testing phase, and the mode's purpose is to permit websites to honor the individual user's consent preferences while still collecting anonymized metrics.
For instance, some privacy laws demand that websites honor a user's preferences regarding cookie use. When someone decides to withhold consent, website owners are deprived of valuable data.
Google's Consent Mode gives website owners a way to remain compliant with international privacy laws while still gaining insight into their businesses.
All in all, many experts believe that the new Consent Mode meshes nicely with Google's efforts to align its services with laws, such as Europe's General Data Protection Regulation (GDPR) and California's Consumer Privacy Act (CCPA).
Let's take a deeper look at this.
There are two new tags (ad_storage and analytics_storage), which Google Consent Mode uses to control the behavior of cookies and Google tags.
Here's what happens:
When your user gives consent, you can use Google Analytics and Google Ads cookies to measure and retarget ads as you usually would because the associate tags will function normally. On the other hand, if a user declines to give consent, then Google's Consent Mode will use pings to convey the message that events have occurred.
Pings are used for events, such as:
When consent is not given, Google Consent Mode allows you to gain conversion measurements from website traffic and Ad campaigns, although you will not get detailed information about your visitors. In other words, you'll still get valuable information even though you won't be able to conduct personalized advertising or retargeting campaigns.
However, Consent Mode changes that dynamic by using the "ad_storage" tag to control cookie behavior and measure conversions. The tag is dependent on the user's consent choice and determines whether Consent Mode uses regular marketing cookies or switches to the use of pings to measure conversions.
Using Consent Mode, you'll be able to respect user privacy while still recording and measuring conversions from the following:
Think of it like this. Suppose a user visits your website and a conversion takes place. If the user accepts all cookies, reporting will continue as usual in your cookie pop-up. On the flip side, if the user declines to give consent and cookies aren't accepted, the ad_storage tag will ensure that marketing cookies are not read or written. In that case, you'll receive a more aggregated level of conversion data.
As previously mentioned, Google Consent Mode works with Google Analytics too. Here too, Consent Mode respects a user's choice to give or withhold consent when it comes to marketing cookies. If users don't consent to all cookies, then Google Analytics will disable features that rely on Google signals.
You'll essentially get information on things like page views and the number of visitors. You won't gain enough data for retargeting purposes.
There are more than a few services, which Consent Mode supports. They include the following:
You'll still gain the following non-identifying, aggregated information when users decline cookies.
Again, while you won't be able to use any of this kind of data for retargeting, you'll still be able to benefit from it by optimizing ad budgets, ad copy, and landing pages.
Today, just about every country has implemented some kind of data privacy law, which regulates how data is collected, the legal basis for that collection, the amount of control users have over their data once it's transferred, and more.
Companies that fail to comply with the relevant legislation face lawsuits, steep fines, and even the banning of the company's website in certain locations.
In order to stay compliant with these laws, companies that want to use tracking technologies that utilize cookies, etc., must gain explicit user consent.
"Natural persons may be associated with online identifiers provided by their devices, applications, tools and protocols, such as internet protocol addresses, cookie identifiers or other identifiers such as radio frequency identification tags. This may leave traces which, in particular when combined with unique identifiers and other information received by the servers, may be used to create profiles of the natural persons and identify them."
The GDPR goes on to clarify what constitutes "consent." According to the law, consent is "the informed, prior, clear and unambiguous indication of a user's wishes." In effect, to be compliant, your users must give explicit consent to your use of their personal information, which according to the GDPR, includes cookies.
Other laws that require consent for the collection and processing of personal information include:
Some may wonder if Google's Consent Mode is actually compliant with data privacy laws since it allows companies to use certain kinds of data via Google Analytics even without consent. According to Google, the answer is yes.
When user consent is declined, all data provided to companies via Google Analytics will be anonymized. The information captured will be delivered in an aggregated form and without a client ID.
However, some German authorities, like the German Federal Court of Justice, disagree with Google's assertions. Their view is that a completely anonymous interaction isn't possible since a website visitor's IP address is transmitted during most interactions.
For instance, the German authorities wrote that:
"If a website operator does not think that collecting consent is necessary, from a technology perspective they must ensure that an anonymous interaction is possible in 100% of users' website interactions ... otherwise consent will always need to be collected."
Despite Google's confidence, and in light of some of the misgivings certain EU authorities may have concerning the use of the tech giant's Consent Mode, it would be prudent to consult with an attorney before adopting its use.
While consulting with an attorney is recommended, as mentioned previously, you can help ensure that you obtain explicit user consent and become GDPR compliant by using a consent management platform on your company's website, such as a cookie banner.
Of course, this can also help remove any potential downsides to using Google's Consent Mode.
Using a cookie consent banner known as a "cookie wall" allows you to block user access to your website until they either explicitly accept all cookies or manage which ones they'll deny or allow. With this model, users have to actively click on a link or a button that says something like "I accept cookies" or "Manage my cookies."
With that said, remember that Google Consent Mode isn't a consent management platform. Obtaining explicit consent is your responsibility, not Google's.
Because Consent Mode is still in beta, you'll need to reach out to your Google account team. There are extra lines of code, which must be added above your Tag manager container or global site tag.
When a user gives consent, Google Consent Mode will collect data as it normally would through Google Ads and Google Analytics. When users withhold consent, Google will anonymize and aggregate data, which it obtains through pings instead of cookies.
Google believes that Consent Mode is an effective method of remaining compliant with worldwide privacy laws regarding customer consent while still obtaining useful data. That information can then be used to help optimize things such as landing pages, ad copy, and budgets.
For instance, by using Google Consent Mode you can still receive basic, non-identifying information when a user has declined analytic cookies. While you won't gain any personal information about that user, you'll still get data on how they arrived, where they're located, and how much time they spend on your website.
In the same way, Google will still be able to show ads even when a customer declines to give consent regarding advertising cookies. Those ads won't be customized or personalized based on that customer's activities or profile, but the topics on your website can still provide Google with some context.
Remember that Consent Mode can potentially help you to comply with worldwide data privacy laws, which demand explicit user consent given in advance of data collection and processing.
These laws include:
Finally, remember that Google Consent Mode is still in beta, and you'll need to speak to your Google account team to get things set up. You'll also already need to be using a consent management system that allows you to obtain explicit cookie consent.
If you're thinking about using Google Consent Mode, you should also consider consulting with an attorney specializing in privacy law in the geographic locations you do business.
