In modern digital marketing, data isn’t just a support tool — it’s the foundation of decision-making.

Accurate conversion tracking is essential for optimizing campaigns, allocating budgets wisely, and reporting results effectively to the business. But what if some user actions — even valuable ones — never make it into your reports?

Enhanced Conversions don’t literally generate more conversions, but they enrich the data behind the conversions that already happened. This allows platforms to more accurately match conversions to clicks, build more relevant audiences, improve targeting, and ultimately enable better-informed marketing decisions.

Today’s reality — restrictions on third-party cookies, cross-device user behavior, delays in form submissions, or incomplete CRM data — all contribute to a growing gap in analytics accuracy. Standard tracking tools often miss some conversions, leaving us with only part of the picture. And when the data is incomplete, the decisions based on it are inevitably less reliable.

A European digital agency faced a similar challenge while actively using Bing Ads in their projects. Some leads were missing from reports, making it difficult to analyze the performance of marketing channels. To regain control over their data, the agency approached the newage. team with a request to implement Enhanced Conversions — a mechanism that helps more accurately attribute existing conversions that may have been lost due to technical or legal limitations.

The Client and the Challenge

The client is a full-service European digital agency specializing in lead generation, performance marketing, and web development. Its focus is on creating effective digital campaigns with high profitability. Among the agency’s clients are businesses from various industries that prioritize not just traffic volume, but lead quality and accurate conversion tracking.

The main challenge was inaccurate conversion tracking in Bing Ads. The standard tracking setup failed to capture a portion of users due to:

• cookie blocking;
• cross-device behavior (e.g., click on mobile → purchase on desktop);
• tracking limitations in browsers like Safari or Firefox.

This resulted in a gap between the actual number of leads and what was reported in Bing Ads. As a consequence:

• the number of recorded conversions appeared lower;
• analytics became less objective and harder to trust;
• optimization algorithms underperformed;
• confidence in data decreased, making it harder to justify campaign effectiveness.

To address the issue, the newage. team proposed implementing Enhanced Conversions — a solution that doesn’t generate more conversions, but helps accurately attribute those that already occurred, yet may have been lost due to cookie restrictions or privacy limitations.

What Are Enhanced Conversions and How Do They Work?

Enhanced Conversions are an advanced tracking method that helps marketers more accurately identify real conversions in digital campaigns — even under modern constraints like cookie restrictions, privacy-focused browsers, and cross-device behavior.

This technology has become increasingly important as standard tracking mechanisms lose accuracy due to evolving privacy regulations and growing user awareness. Enhanced Conversions allow advertisers to match conversions to clicks more reliably by using first-party data (such as emails or phone numbers) — improving attribution without violating user privacy.

How Enhanced Conversions Work

Enhanced Conversions operate by transmitting hashed user contact data (such as an email address or phone number) collected during form submissions or other conversion actions.

Here’s how it works step by step:

1. A user sees an ad (e.g., on Bing Ads) and clicks through to the website.
2. They complete a conversion — such as submitting a form, making a purchase, or subscribing.
3. The website collects contact details, which are hashed (i.e., encrypted) using secure algorithms.
4. These hashed data are sent to the advertising platform, which matches them against click data.
5. If there’s a match, the conversion is recorded — even if cookies were blocked or the action happened on a different device.

What Are the Benefits of Enhanced Conversions

• More accurate tracking: Conversions are recorded even if cookies or browser trackers fail.
• Cross-device support: If a user clicks on an ad via mobile but completes a purchase on a laptop, the system still attributes the conversion correctly.
• Fewer “lost” data points: Hashed contact information helps offset browser and ad blocker limitations.
• Privacy-compliant and secure: Data is transmitted in encrypted form, meeting GDPR, CCPA, and other privacy regulations.
• Improved analytics: More precise conversion data means better insights and more effective campaign optimization.

Why Standard Tracking Is No Longer Enough

In the past, ad platforms could reliably track user actions using third-party cookies. But the landscape has changed:

• Users increasingly block trackers and cookies;
• Browsers like Safari, Firefox, and Brave restrict tracking by default;
• Cross-device behavior is the norm, breaking the link between the ad click and the conversion;
• Privacy laws, such as GDPR and CCPA, limit data collection without user consent.

As a result, ad campaigns “see” less than what actually happens, leading to gaps in analytics and reduced optimization accuracy.

Enhanced Conversions isn’t a brand-new tracking method, but rather a mechanism for improving the transmission of first-party data. It increases the chances of accurate conversion attribution within advertising platforms.

Implementation: Enhanced Conversions Technical Architecture

To implement Enhanced Conversions for Bing Ads (Microsoft Advertising), we built a transparent, secure, and scalable integration that meets both technical and legal requirements. Below is a step-by-step breakdown of how the architecture was implemented.

Set up via Google Tag Manager

For convenience, scalability, and flexibility, we used Google Tag Manager (GTM). This approach enabled us to:

• centrally manage all tags;
• quickly update configurations without modifying site code;
• implement custom data transmission via dataLayer.

In GTM, we created separate tags:

• to track specific events (e.g., form submissions);
• to transmit hashed data to the UET (Universal Event Tracking) system.

Next, we implemented the UET (Universal Event Tracking) Tag — the standard tracking code used by Bing Ads. It was placed on the website to capture user interaction events.

UET serves as the Bing Ads equivalent of the Google Ads Conversion Tag. It acts as the entry point for analytics and Enhanced Conversions within the Microsoft Ads ecosystem.

Hashed Contact Data from Forms

After a conversion occurs (for example, when a user submits a form on the website), their contact details — such as name, email address, and phone number — are captured.

These data points are:

• hashed using SHA-256, the algorithm recommended by Microsoft;
• sent to Bing Ads as part of the Enhanced Conversions payload;
• not stored or transmitted in plain text — only securely encrypted (hashed) values are shared.

This way, the data remains confidential, but can still be matched with click information in Microsoft Ads for more accurate conversion attribution.

Validation via UET Tag Helper

To ensure correct implementation, we used UET Tag Helper — the official browser extension from Microsoft. It allows you to:

• verify whether the tag is firing correctly on the page;
• check if hashed data is being sent properly;
• detect any errors or misconfigurations in real time.

Through this testing process, we confirmed that:

• events are consistently triggered and tracked;
• data is hashed correctly using the required format;
• conversions are properly attributed and recorded in the Microsoft Ads dashboard.

This architecture not only solves the issue of inaccurate tracking but also creates a flexible foundation for future integrations — such as connecting a CRM or other advertising platforms.

Results: How Analytics Improved After Implementation

After implementing Enhanced Conversions, the team gained a significantly higher level of analytical accuracy. This solution not only allowed them to “see more,” but also empowered them to make better-informed marketing decisions.

Improved Conversion Tracking

Immediately after launching Enhanced Conversions, Bing Ads reporting showed a noticeable increase in recorded conversions. Previously, some user interactions went untracked due to technical limitations (such as cookie restrictions, cross-device behavior, and browser blockers). With Enhanced Conversions, part of this lost data was recovered in the analytics.

This enabled the team to:

• calculate ROAS (Return on Ad Spend) more accurately;
• gain better control over CPA (Cost per Acquisition);
• eliminate the “underreported” performance in advertising reports.

Reducing the Gap Between CRM and Ads

One of the key challenges was the mismatch between actual business results and analytics data in ad platforms. After the integration:

• Bing Ads data began to align more closely with CRM figures;
• the gap between the real number of leads and what the ad system reported was significantly reduced;
• reports started reflecting the true performance of campaigns — a critical factor for decision-making.

Enhanced Conversions became a bridge between raw advertising data and real business metrics. This solution elevated tracking to a new level — free from unnecessary noise and data loss.

Insights and Advantages

The implementation of Enhanced Conversions brought more than just local improvements within Bing Ads — it became a key enabler of broader strategic benefits in multichannel marketing.

It’s Not Just About Bing

While this case focused on Bing Ads, the Enhanced Conversions mechanism is universal and easily adaptable across other platforms like Google Ads, Meta Ads, TikTok Ads, and more. The core value lies in transmitting hashed contact data (such as email or phone number) collected via website forms. This allows advertising systems to more accurately match clicks to user actions — even in cases where tracking is blocked or users interact across multiple devices.

In other words, it’s a way to restore the missing link in the user journey funnel.

Standardization as a Foundation for Scaling

The implementation of Enhanced Conversions wasn’t a one-off technical patch. It’s a structured, repeatable solution that can be replicated:

• across other projects,
• for different clients,
• in various advertising channels.

Standardizing this process opens the door to faster analytics deployment — regardless of campaign complexity or client specifics. It provides both agencies and businesses with a scalable tracking infrastructure.

A Tool for Strategic Decision-Making

Enhanced Conversions aren’t just about data — they’re about the quality of the decisions built on that data. When analytics are accurate and aligned with reality, the team gains:

• confidence in identifying which campaigns truly perform,
• the ability to adjust budgets in real time,
• flexibility to scale without losing control over performance.

The result? Fewer assumptions, more facts — and ultimately, stronger strategies.

This case proves: even a targeted improvement in tracking can have a long-term, multiplatform impact.

Conclusion: More Data — Better Decisions

Accurate analytics are the foundation of modern marketing. Enhanced Conversions help restore the missing link between user actions and reporting — especially when standard tracking tools no longer provide the full picture.

This case showed how even a partial improvement in tracking within Bing Ads led to:

• an increase in the number of recorded conversions,
• improvements in key performance metrics,
• alignment between advertising reports and internal business data.

It’s not just about more accurate numbers — it’s about making better decisions based on reliable information.
