Adblockers VS Premium Content : The Server-Side solution

Adblockers VS Premium Content : The Server-Side solution

The digital age has brought an abundance of information, but also an advertising saturation for internet users. Faced with this overload, Adblockers emerged and quickly became essential tools for many users. Whether for uninterrupted browsing or for reasons of personal data protection, their use is sharply increasing. However, their implications go far beyond just blocking ads.

While the main purpose of these tools is to block unwanted ads, their impact doesn't end there. They affect the launching of crucial scripts, whether they're dedicated to advertising (like Facebook or Google Ads) or essential for the proper functioning of sites. Some even go further by blocking analysis tools. These adblockers can impact a company's ability to measure their site traffic or restrict access to certain content.

The consequence ? An underestimation of traffic, reduced advertising campaign efficiency, and even disabling crucial tools like paywalls meant to protect premium content.

Statistics show that nearly a third of French internet users use these blockers. As their usage continues to grow, it poses significant challenges for website owners. But how can users be guaranteed a non-intrusive ad experience while preserving website integrity and functionality? The Server-Side solution seems promising, combining site performance improvement, increased cookie collection, consumer data protection, and data governance.

The challenge posed by ad blockers is exemplified by the case of "La Revue du Praticien". How can the protection of premium content against an adblocker be guaranteed ?

La Revue du Praticien, a key player in ongoing medical training, has carved a niche within the health professional community. As a valuable resource, it offers specialized content for doctors, medical students, nurses, and other healthcare professionals. However, this exclusive access is restricted to subscribers, requiring rigorous authentication.

Here lies the real challenge : how to ensure the protection of this premium content ? The key to this protection is the reliable triggering of the Paywall Poool tool. For La Revue du Praticien, this tool isn't just a feature : it's the cornerstone of its business model. But ad blockers threatened its efficacy, risking exposing premium content.

For La Revue du Praticien, this situation had a direct and serious implication. Indeed, when a user had an ad blocker, they could access the premium content without identification, equivalent to a significant security breach, endangering the site's business model. Imagine the potential losses when non-subscribers access content that is normally reserved, thus undermining the site's profitability and longevity. This major challenge required a robust, suitable, and lasting solution.

The Solution

Given the critical importance of ensuring premium content protection, La Revue du Praticien chose an innovative solution : the proxyfication of GTM (Google Tag Manager) and Poool.

GTM Strategy Overhaul

The main challenge encountered was third-party tools blocking the GTM script. The solution was to switch to “first party” hosting and customize the script file (from gtm.js to a custom name). This approach made the script invisible to most ad blockers.
Server-Side Integration of Poool

Besides the GTM challenge, the Poool script, crucial for content protection, was also optimized. To prevent script blocking and simultaneously improve site performance, Poool was integrated into GTM in Server-Side mode. This not only reduced the number of scripts loaded on the user's browser side but also ensured that Poool, hosted in "first party" mode, operated optimally, even in the presence of aggressive ad blockers. And as a bonus, transitioning these six scripts was made smooth thanks to our CDN Addingwell technology !

By combining these innovative techniques, La Revue du Praticien not only strengthened its premium content protection but also optimized its website's performance, ensuring an unprecedented user experience.

The Results

As we observed, for La Revue du Praticien, transitioning to a Server-Side approach with Google Tag Manager (GTM) wasn't just a technical solution but a necessity to preserve its business model.

The Server-Side migration yielded impressive results in terms of content protection, user engagement, and conversions.

Impact on technical performance and proper premium content protection

Before the migration : 10% of the time, premium pages were accessible without restrictions due to ad blockers, directly threatening the revenue generated by these exclusive contents.

After the migration : Content protection reached 100%. This means that regardless of the browser used, premium content is now properly protected. 

Commercial impact

Before the migration
Fluctuations in page views and varying monetization due to users accessing content for free using ad blockers.

After the migration
1. Page views increase : Following the optimization, a significant 10% increase in page views was recorded. This figure is even more impressive since no specific media action was launched during this period.
2. Paywall impressions increase : Paywall impressions also saw a 10% rise.
3. Conversions and Engagement : The number of clicks leading to subscriptions and the number of account creations increased by 9%.

By migrating to Server-Side hosting with GTM, La Revue du Praticien not only enhanced its content protection but also saw a tangible increase in user engagement and conversions.


Adblockers, originally designed to offer a smoother browsing experience for internet users, have posed significant challenges for La Revue du Praticien, especially those relying on premium content to support their business model.

The case of La Revue du Praticien perfectly illustrates the delicate balance many sites must find : ensuring an optimal user experience while preserving their content's intrinsic value. Thanks to migrating to a Server-Side approach, not only was the protection of their valuable content strengthened, but a significant increase in user engagement and conversions was also achieved.
