Funnel analytics explained: how to optimize conversions without tracking users
Funnel analytics gives businesses insight into important user behavior metrics that help optimize the customer journey and improve conversions.
Traditional funnel analytics buys its granular targeting and precise optimizations at a price: it is rarely in line with modern privacy and compliance standards.
And while many tracking tools are labeled privacy-friendly, they still process personal data, falling short of true privacy and ethical standards.
Why businesses should care about funnel analytics
Funnel analytics is the process of mapping and tracking the steps users and leads take, from the point where they enter the funnel to a successful conversion or a drop-off.
Businesses use funnel analysis to visualize and track the user journey through a predefined conversion path. They can identify weak points in the conversion funnel and bottlenecks where users drop off.
Identifying weak points, testing, and optimizing allow businesses to improve the ROI (return on investment) of their marketing and sales efforts and increase conversion rates. That is especially important for large websites and ecommerce stores, where even the slightest change in the number of users going through each funnel step can result in significant revenue changes.
Unfortunately, most granular analytics tools rely on tracking methods that raise privacy concerns.
Privacy issues with traditional funnel analytics
Most traditional funnel analytics software relies on tracking methods such as third-party cookies and precise user profiling.
Cookies are small pieces of code quietly stored in web browsers after a user visits a web page for the first time. Cookies not only track user behavior on that website, they remain active in the background and keep tracking across websites.
While this tracking may seem justified in the context of marketing strategies, since leads usually don’t convert after the first visit, the amount of information gathered about user preferences and behavior is a cause of privacy concerns.
Moreover, traditional cookie-based analytics tools like Google Analytics indirectly offer that data to advertisers via Google Ads. Personal data is one of the main reasons such services are free.
How personal data became a highly sought commodity
Even though advertisers don’t get access to personally identifiable information such as names, social security numbers, and similar, data about user preferences, purchasing habits, and detailed behavioral breakdowns can be combined to create user profiles. Based on that information, platforms offer advertisers ways to target the end user with precise ads.
Cookies and user profiling contribute to concerns regarding persistent, targeted advertising. However, even without intrusive ads, the sheer volume of information collected about individuals presents privacy risks. There have been notorious cases of major brands misusing private information based solely on purchasing habits.
Due to the rising number of concerns, regulators realized they needed to intervene, as the existing legal framework proved insufficient to protect user privacy online.
Significant privacy-related legislative changes
While legislators addressed the issue through regulations like the ePrivacy Directive, another EU law reshaped the privacy sector globally.
The General Data Protection Regulation (GDPR) was, and still is, the groundbreaking framework that changed how businesses collect and process personal data, especially in the digital sphere.
After the GDPR, explicit user consent is required before cookies are stored in web browsers. As a result, if businesses wanted to use cookie-based funnel analytics, they needed to present users with cookie consent banners.
The GDPR applies even to non-EU companies as long as they process the personal data of EU citizens. The EU is a major market, which is why many companies complied with the GDPR to maintain access to it.
GDPR fines
The GDPR is also effective because of its fines. Failing to comply with GDPR standards can lead to fines of as much as 4% of a company’s global annual turnover in the previous year.
It is important to note that fines are based on total turnover, not net profit, and that the regulation reaches far beyond the EU’s borders. Authorities have already issued penalties reaching hundreds of millions, even exceeding a billion euros.
GDPR global reach
The GDPR influenced not only global companies but also legislators. Even though the US does not have a federal data protection regulation, more and more states are regulating the field.
The most significant example is the California Consumer Privacy Act (CCPA), as California is a large tech market home to many big companies residing in Silicon Valley.
Users are becoming more privacy-aware
Legislators were not the only ones to address the privacy concerns raised, nor were they the first. Due to whistleblowers like Edward Snowden, people started taking better care of their online privacy.
As a result, besides rejecting unnecessary cookies, privacy-aware users rely on tools such as ad and cookie blockers, VPNs, private browsers, and incognito modes to cloak their traffic. That has two main effects:
- Reducing the accuracy of cookie-based analytics, which relies on granular profiling
- Increasing user concerns about data consent requests and privacy ethics
So not only is cookie-based funnel analytics less accurate than it used to be, it also raises privacy concerns among users who do not want their personal data processed for marketing purposes, affecting brand reputation and ethical standards.
Why many cookieless solutions are not truly privacy-preserving
With the rise of privacy concerns and the compliance headaches surrounding them, some businesses began seeking alternatives to cookie-based analytics.
As a result, many privacy-friendly analytics platforms started emerging on the market, promising compliance by not relying on third-party cookies for data collection.
The real issue is unnecessary personal data processing
Third-party cookies, on their own, are just one method for collecting personal data. Cross-site tracking and data brokering are intrusive, and removing them is a step in the right direction, but doing only that is not enough.
Removing cookies but tracking personal data differently, even when the same purpose can be achieved without personal data tracking, opposes one of the key privacy principles highlighted in the GDPR: data minimization.
So, even though privacy-friendly analytics tools do not rely on third-party cookies, they still process personal data in other ways.
Hidden tracking methods
Instead of cookies, privacy-friendly analytics tools implement several different methods to gather data.
One example is IP hashing, a method of encoding an IP address for privacy. Even though the result is privacy-friendly, the act of hashing is still personal data processing, as the IP address is considered personal data.
Therefore, personal data processing still requires consent even if no cookies are used. Regardless of the claims of privacy-friendly cookieless tracking solutions, you will still be required to show consent banners.
The same goes for user profiling, session storage, local storage, and different types of fingerprinting. Even if the website visitor tracking software does not rely on raw personally identifiable information, the combined data it uses can be traced back to individual users, which makes it personal data processing.
What a truly cookieless and GDPR-compliant funnel analytics solution looks like
A truly cookieless and GDPR-compliant funnel analytics solution should be private by design. Only privacy-first software that processes no personal data can skip consent banners while remaining GDPR compliant.
mandera is a privacy-first, agentic website growth system. Its analytics suite measures everything happening on your website without cookies or personal data, and the rest of the system turns that data into growth opportunities, strategies and content. Here is how its analytics give you actionable website traffic insights without infringing privacy:
No cookies, no IP tracking, no fingerprinting
mandera does not process any personal data. And if no personal data is collected, no consent is required.
IP addresses are removed from every request, and no user profiling exists. mandera only works with aggregated signals that cannot be traced back to individual users:
- the page that was opened
- the traffic source, taken from the referrer or from campaign parameters such as utm_source
- the country, derived from the browser timezone, never from an IP address
- the language, from the browser setting
- screen and window size
- engagement, such as time on page, clicks and scroll depth
- the device, browser and operating system, in shortened form
Combined, that data is sufficient to count a unique visit, allowing mandera to show accurate metrics without infringing privacy. You can read exactly how this works in the how we track documentation.
Real visitor flows, aggregated and anonymous
To be upfront about it: mandera is not a classic funnel tool, and there are no funnel steps to define. Instead, mandera’s User Flow maps the real paths visitors take through your site, aggregated and anonymous, so you see where people go next and where they leave.
You see where visitors enter your website, which pages they move to next, and at which point they drop off. That covers the core job a funnel is supposed to do for you: revealing the weak points in the journey toward conversion. And because the flows are built from real aggregated visits rather than a predefined step sequence, you also catch the paths you did not expect, such as visitors detouring to a pricing or FAQ page before they convert.
That allows you to make funnel-style improvements while staying GDPR compliant by design, without tracking individual behavior.
Private but accurate measurement
Because mandera does not process personal data, its analytics are not affected by VPNs, ad blockers, private browsers, and incognito modes.
You get accurate website traffic data you can actually understand and use, displayed in a clean and intuitive dashboard.
Clean UX, stronger brand reputation
Because personal data is not processed, visitors can focus on your content without having their experience interrupted by consent banners.
Moreover, the fact that you care about visitor privacy by implementing privacy-first solutions will strengthen your brand reputation, as privacy-aware visitors respect businesses that maintain high ethical standards.
The limitations of privacy-first analytics
While privacy-first analytics gives you an accurate website tracking overview without tracking individual visitors, that level of privacy does not come without limitations.
If you want granular tracking that lets you, for instance, accurately A/B test several funnel scenarios on the level of individual users, you will still need to rely on cookie-based conversion funnel analysis. Those tools give you detailed insights about each step users take through your funnel, allowing you to make pinpoint optimizations.
While granular funnel analysis helps with precise targeting, it remains a growing privacy and compliance concern. If you want to use it, do so with explicit user consent and in the minimal way necessary to achieve your marketing goals.
Frequently asked questions
Can I do funnel analysis without tracking individual users?
You can answer the core funnel question, where people drop off on the way to conversion, from aggregated visitor paths. What you cannot do without identifiers is follow one specific user step by step across sessions.
Is funnel tracking GDPR compliant?
It depends on the method. Funnels built on user identifiers or cookies process personal data and need consent. Aggregated path analysis that never identifies a person does not.
What is the difference between a funnel and a user flow?
A funnel is a predefined sequence of steps you expect visitors to follow. A user flow shows the real paths visitors actually take, including the detours and exits you did not plan for.
Beyond analytics
Measuring traffic is where mandera starts, not where it ends. Everything the analytics suite collects flows into mandera’s Agentic Engine, which surfaces growth opportunities from your own data and helps you turn them into strategies and content, while you approve everything that touches your site.
Our conclusion
While traditional funnel analytics often includes granular user tracking and enables detailed campaign optimization, it frequently compromises privacy.
Privacy-friendly tools do not have the same targeting capabilities, and they do a better job privacy-wise, as they eliminate cookies and direct profiling. However, they still process personal data, requiring consent screens.
Privacy-first tools take the final step. Because no personal data is processed, no consent banners are required, the user experience stays clean, and brand reputation improves among privacy-aware users. And with real aggregated visitor flows, they answer the most important funnel question, where people drop off, without defining a single funnel step.
