Your Magento e-commerce needs a high-performance CMP in 2026.

You manage a B2B e-commerce platform on Magento Adobe Commerce and you are wondering why investing time and resources in a Consent Management Platform (CMP) is necessary. After all, your customers are professionals, not average consumers. Well, think again: consent management is just as important in B2B (from both a commercial and regulatory point of view), and it can even become a competitive advantage.
CMPs in B2B are far too often underestimated
Contrary to common belief, the GDPR applies to all websites that collect personal data, including in a B2B context. When a professional buyer browses your Magento platform, you collect data about their behavior, preferences, and interactions. This information is valuable for personalizing the buying experience and optimizing your marketing campaigns.
In this way, without a properly implemented CMP, you expose yourself to several risks. First, legal risks. Indeed, CNIL sanctions can reach 4% of global annual turnover or €20 million. Next, a loss of trust: your B2B customers are particularly sensitive to the protection of their professional data. And finally, marketing inefficiency, since without valid consent, your analytics tools and advertising platforms run empty.
On Magento and Adobe Commerce, B2B journeys are complex. Your customers browse through company accounts, consult catalogs, generate quotes, and place recurring orders. Each of their actions generates data that you could use to improve customer lifetime value. But the issue is that without a suitable CMP, and above all one that is properly configured (because simply displaying a cookie banner is not enough to be compliant), you do not have the legal authorization to use this data for your campaigns, behavioral analyses, or recommendations. And this is far from trivial. If you imagine losing 80% of your ability to track visitors simply because your cookie banner is poorly configured, that represents a real loss of revenue.
And this is exactly what is happening today on many B2B platforms. Technical teams install a CMP in “quick install” mode, without optimization, and then observe a brutal drop in the effectiveness of their Google Ads or LinkedIn campaigns. Traffic appears as “unassigned” in Google Analytics 4, marketing budgets are spent blindly, and ROI collapses. And that’s without mentioning teams that install a CMP on their site with absolutely no technical configuration behind it.
The four pillars of an effective CMP
- 1. Native technical integration
Your CMP must integrate perfectly with the Magento / Adobe Commerce ecosystem. This means native compatibility with Adobe Analytics, Google Tag Manager, and all of your marketing tools. The integration must automatically manage the triggering or blocking of tags based on user consent.
On Magento, you must also take into account multi-store and multi-currency specificities. If you operate in multiple countries, your CMP must manage different local regulations and display banners adapted to each market (different languages and regulations, for example).
- 2. Consent rate optimization
A default cookie banner generates an average acceptance rate of 40 to 60%. With advanced design and UX optimization, this rate can reach 75 to 85%. And this difference is massive for your marketing campaigns.
To achieve this, we recommend optimizing your pop-in in order to force interaction (positive or negative) with the user. Remember that all buttons must have a similar size and visual appearance, so as not to encourage one choice over another. The “Accept” and “Reject” buttons must be visually identical. Of course, by maintaining this consistency, you expose yourself to more refusals from users. But do not forget current accessibility standards! We have shared an article on this topic [LINK TO THE ARTICLE], which you should read after finishing this one.
Also note that every detail matters: color customization, banner position, clarity of the message—leave nothing to chance in order to maximize your chances.
- 3. Consent signal transmission
Your CMP must properly transmit consent signals to all vendors with whom you share your users’ data. GA4, Google Ads, YouTube, Facebook Pixel… all of them must only fire after explicit user consent has been given. Without this transmission, your tools cannot differentiate users who have consented from those who have refused.
On Magento, for example, this implies precise configuration of Google Tag Manager so that each tag is conditioned on the appropriate consent. For instance, your Google Ads tag must only fire if the user has accepted advertising cookies via your CMP banner. Otherwise, you risk not only compliance issues, but also polluted data.
The same applies to vendors such as Google Maps or embedded content like YouTube. Technically, you must block the display of these contents until the user has given consent for data collection by the relevant provider.
And to do this, several technical actions are required. This is where we support you, so that you no longer have anything to manage.
- 4. Performance monitoring
Once your CMP is in place, the work does not stop there. You must continuously monitor several KPIs: banner interaction rate (how many users actually interact), consent rate (how many accept), refusal rate, and above all the evolution of “unassigned” traffic in GA4.
Truly effective monitoring must allow you to quickly detect anomalies. For example, if your “unassigned” traffic suddenly explodes, it is a sign that your CMP is no longer functioning correctly and that you are losing critical marketing data.
Axeptio is our winning partner for B2B
As a digital agency specialized in B2B e-commerce on Magento, we often recommend Axeptio among CMP solutions on the market, because it clearly stands out for its alignment with B2B platform challenges. This French solution combines a highly user-experience-oriented approach with great ease of deployment: the interface is intuitive, consent banners are fully customizable (design, wording, user journeys), and integration is seamless both with Magento and with leading analytics tools and the Adobe ecosystem.
Axeptio makes it possible to efficiently manage the collection and secure storage of consents, centralize data to facilitate reporting, and simplify GDPR compliance across all your sites, including within the framework of Google Consent Mode V2, which has imposed new transparency signals (advertising and personalization) since March 6, 2024. Marketing teams gain autonomy thanks to administration without technical dependency, while the granular management of cookies (essential, functional, analytics, marketing) perfectly meets the expectations of professional clients.
Common false starts to avoid
However, one of the most common mistakes is to consider the CMP as a simple technical constraint to deal with quickly. An approximate implementation can have serious consequences: significant loss of marketing effectiveness (unusable data, biased campaigns) and exposure to major financial risks in the event of a CNIL audit, potentially representing tens of thousands of euros.
The second major mistake is to apply a B2C configuration as-is to a B2B site. Usage logic, user journeys, and expectations differ greatly: professional clients are generally less tolerant of tracking perceived as intrusive, while being more willing to accept certain data processing when they clearly understand the added value for their experience and commercial relationship.
The third point that is often underestimated: mobile. B2B buyers increasingly browse catalogs, view product pages, and place orders from their smartphones. A poorly designed or non-responsive consent banner can degrade the experience, slow down navigation, and directly impact conversion.
Do not neglect team training. A CMP is not just a compliance tool: it is a strategic lever. Marketing, sales, and technical teams must share a common understanding of how it works and what is at stake, in order to fully leverage data, in full compliance and in the service of performance.
In 2025, a high-performance CMP is no longer an option for an e-commerce platform: it is a strategic investment that directly conditions the effectiveness of your digital marketing, the reliability of your data, and above all the long-term trust of your customers. A well-designed CMP becomes a true performance driver, reconciling regulatory compliance, user experience, and intelligent data exploitation.
