It’s one thing to track affiliate-driven customers on your website and another thing to track them to a granular level, developing a fully-fledged lead profile based on their interactions with your website elements.
Yes, I’m talking about website visitor tracking and how it can change the game for you, an affiliate marketer who buys or sells website traffic. Imagine knowing what draws attention, where they click, how they scroll, and which website elements trigger conversions.
With this knowledge, you can be so much more cost-effective. No less importantly, a well-thought-out web visitor tracking system ensures you stay on the legal side of the fence, not worrying about compliance, affiliate fraud, or any other risks.
“Phonexa serves pretty much anyone in the customer acquisition space, whether that’s media buyers, affiliates, brands – anyone looking to grow their book of customers or generate customers for other product providers and track their marketing from an end-to-end perspective, all the way from the first impression – where this customer first sees your advertising – to the final destination of buying your product.” – David Pickard, CEO at Phonexa |

Read on to learn more about website visitor tracking and how it can grow your business.
What Is Website Visitor Tracking?
Website visitor tracking is recording and analyzing the engagement of referred customers, including clicks, form fills, quote requests, sign-ups, downloads, and other interactions that have value for your marketing strategies and that you can quantify.
Example: You’ve got 5,000 clicks and only 5 quote requests, a disappointing 0.1% conversion rate. Through website tracking, you can identify the exact time and place where leads disengage; for example, you may have too many questions or fields on your form. Then you can fix it.
Here’s how it looks within Phonexa’s web visitor tracking dashboard:

What Insights Can You Get Through Website Tracking?
Traffic Insights | Once referred customers land on your website, you can track their location, traffic source, device, operating system, and browser. Example: If your traffic is 95% mobile users, it makes sense to work on mobile-friendliness and only count mobile traffic when developing your semantic core. |
Conversion Insights | The number of leads, signups, and sales reflects how well your referred users convert. Example: If blog post A gets 1,000 clicks and only 5 conversions, while blog post B gets 500 clicks and 25 conversions, you can analyze what makes the difference: source, targeting, CTAs, content itself, etc. |
Behavioral Insights | Metrics like time on site, drop-off points, and post-click behavior can help you segment user groups and hone in on the ideal buyer. Example: If users spend less than 10 seconds on your landing page, you might want to move CTAs to the first screen. Read also: How To Maximize Landing Pages With User Behavior Tracking |
Web visitor tracking can also reveal technical problems, like slow page loading speed or other performance issues. Speaking of which, 85% of shoppers will avoid an online business with performance issues, while every second of delay in page load speed drops page views by 11%, conversion rates by 7%, and customer satisfaction rates by 16%.
That’s what I’m talking about – website visitor tracking is so underrated!

Website Visitor Tracking: 3 Steps To Unlocking Affiliate Traffic Insights
Step 1. Set Your Goals and KPIs
First, identify the data you want to measure: clicks, form submissions, purchases, account registrations, or all of that. Next, knowing the insights you focus on, you can define your KPIs – such as click-through rate and conversion rate – and track your performance.
Attribution Model
As an advertiser, you must ensure all referred customers are unmistakably attributed to affiliates, with the latter receiving timely and fair commission for driving traffic.
Here are the most popular attribution models:
Last-click attribution | The affiliate whose link was clicked last gets full credit |
First-click attribution | The affiliate whose link was clicked first gets full credit |
Multi-touch attribution | Credit is split among multiple or all affiliates proportionally to their contribution |
The right attribution model will incentivize affiliates to send high-intent traffic to your website, reflected in objective website tracking metrics. Likewise, more traffic will pass your qualification criteria, resulting in sales and commission payouts.
Tracking Parameters
Tracking parameters are UTM codes (for example, ?utm_source=affiliate&utm_campaign=sale) or affiliate IDs (for example, ?aff_id=123) added to affiliate links to help you know which referred customer was sent by which affiliate.
Here’s why UTM codes and affiliate IDs are crucial for website visitor tracking:
- If two or more affiliates use the same UTM code or affiliate ID, you cannot attribute the conversion to the right affiliate and therefore don’t know whom you should pay.
- If the UTM code or affiliate ID is incorrect – for example, ?aff_id= with no number – your web tracking system won’t know who sent the affiliate referral.
- If the UTM code or affiliate IDs are confusing – for example, utm_source=aff1 for one affiliate and ?utm_source=affiliate1 for another – your reports might split the same data into different categories.
Do the following to ensure correct website tracking for your affiliate marketing campaigns:
- Make sure all your affiliates have unique IDs and use clear and consistent UTM codes
- Add sub-IDs to track specific campaigns and sources; for example, ?sub_id=blog_post1 for affiliate links in a blog post
- Test your affiliate links before providing them to affiliates.

Step 2. Choose Your Website Tracking Method
In my opinion, there are only three practical website tracking methods:
- Cookies
- Tracking pixels
- Server-to-Server (S2S) tracking
As for the other web visitor tracking methods – fingerprinting, supercookies, cached content tracking, session-based tracking, user ID tracking, etc. – none of them are reliable and insightful enough.
Cookies
Inserting a first-party cookie into the user’s browser – a small piece of data that your website stores in the user’s browser to remember things like their login info, what’s in their shopping cart, their location, language, and other preferences – you attribute conversion to affiliates and track important engagement details.
That said, browser restrictions – for example, Safari limits cookies to 7 days – and consent requirements somehow restrict the potential of cookies and force you to use cookie consent banners, which also means some referrals will deny using cookies.

How To Choose an Optimal Cookie Window
Choosing an optimal cookie window is about paying affiliates who contributed to a conversion while not paying for the clicks made so long ago that they did not affect the conversion. An overly long cookie window might increase commissions and decrease web tracking accuracy.
I suggest considering the length of the sales cycle. In high-ticket affiliate marketing, 30 to 90 days might be optimal; for impulse purchases, you might need a shorter cookie window.
Recommended Cookie Window Duration by Industry
Insurance | 30–60 days |
Finance | 13–30 days |
Home Services | 30–45 days |
Legal | 30–60 days |
Solar | 60–90 days |
Tracking Pixels
A tracking pixel is a simple JavaScript or tag hosted on a third-party server to track affiliate website visitors. To use it, add a ready-made tag to the page you want to analyze, such as a thank-you page after a purchase or sign-up.
There are four ways of using tracking pixels for website visitor tracking:
iFrame | Placed as an inline frame on a website’s landing page |
Image | Set up as an image or 1×1 GIF on the site’s landing page |
JS | Added as a script to the site code to track affiliate visitors |
S2S postback | A click ID attached to any user’s click; best for counting conversions |
Tracking pixels allow you to collect anonymized affiliate data, such as which affiliate drove a conversion and the type of action (form submission, sale, etc.). Meta, TikTok, Google, and affiliate networks like Impact and ShareASale use tracking pixels. That said, forgotten pixels – ones no longer actively monitored and maintained – are not uncommon either.
Server-to-Server (S2S) Tracking
Server-to-Server (S2S) tracking, or postback tracking, is the most advanced website visitor tracking method, where the advertiser’s server communicates directly with the affiliate platform’s server to record clicks and conversions, bypassing the user’s browser entirely.
Here’s how S2S affiliate tracking works:
- A user clicks an affiliate link – for example, www.yourstore.com?aff_id=123&click_id=xyz123 – which contains the affiliate ID (123) to identify the affiliate and the click ID (xyz123) unique to that specific click and session.
- When the user lands on your (the advertiser’s) website, your server logs the click ID and affiliate ID in your database without setting a cookie in the user’s browser. Now you can track what they do on your website.
- Upon the conversion (say, the affiliate made a $50 purchase), the advertiser’s server identifies the click ID, attributes the conversion, and sends a postback request – a server-to-server message that includes click ID, affiliate ID, and conversion details to the affiliate platform’s server: https://affiliateplatform.com/postback?click_id=xyz123&aff_id=123&amount=50
- The affiliate platform (network) matches the click ID with its database (the affiliate link itself is usually created in the affiliate network’s system), pays a commission to the affiliate, and logs the conversion in the affiliate dashboard.
S2S tracking is reliable, privacy-compliant, and fraud-resistant. Likewise, it’s unaffected by cookie-blocking, ad-blocking, and browser restrictions.
Cross-Website Tracking: How To Ensure Tracking Consistency
It’s no secret that the customer journey is multi-channel: a typical customer switches between devices and platforms several times during their purchase history, starting in a mobile browser, continuing on a desktop, and finishing in an app.
This is quite challenging because cookies and pixels fail to maintain continuity across different environments. For instance, a cookie set on a mobile browser may not persist on a desktop, resulting in incomplete attribution and lost commissions.
Example: A user clicks an affiliate link on their mobile browser and explores the website, but does not download the app immediately. In a few days, they see a retargeting ad on their PC, download the app, and buy a subscription.
In this scenario, you need cross-website, or cross-device, tracking to attribute the conversion.
Here are the two major ways to preserve attribution across websites and devices:
- Server-to-Server (S2S) Tracking: As I’ve already mentioned, S2S tracking logs affiliate data directly on the advertiser’s server and shares it with the affiliate platform. So, tracking remains accurate even when users switch between the web and app.
- Deterministic and probabilistic website tracking
- Deterministic website tracking relies on data users intentionally share with a company (zero-party data) through forms, surveys, account registrations, etc.
For example, if a user clicks an affiliate link on their phone and later logs into your website on a desktop with the same email, the web tracking system can attribute both actions to the same user.
- Probabilistic website tracking predicts user actions based on historical patterns, like how users with similar IP addresses, device types, or browser settings behaved in the past.
Combining deterministic and probabilistic tracking is a great strategy for measuring on-site user behavior without S2S tracking. However, even if you use S2S tracking, which is inherently deterministic, you can also use probabilistic tracking to address cases like anonymous ToFu users and cross-device journeys without logins.

Step 3. Choose Your Web Visitor Tracking Solution
Once you’ve identified what you track and how, you need to choose the website tracking software that can do it, and that’s not an ordinary task. Free affiliate web tracking tools like Google Analytics 4 only provide basic insights, while enterprise-grade solutions like Adobe Analytics might cost you over $50,000 annually.
Here’s what I would recommend: For starters, use Google Analytics 4 (it’s free). Once you’ve got the hang of it, take your website visitor tracking a step further with a cost-effective website tracking software like Phonexa.
Best Free Website Visitor Tracking Platform – Google Analytics 4
Google Analytics 4 (GA4) is a leading free website visitor tracking solution that provides, among other things, cross-platform tracking and analytics.
- Behavior Flow: Visualize user journeys from entry to exit
- User Explorer: Track anonymized user activity with chronological event timelines
- Audiences: Segment users by location, intent, and new vs. returning visitors
GA4 might be a solution to rely on in the beginning, but it has several significant disadvantages:
- It cannot map UTM data to affiliate IDs, calculate commissions, or handle payouts, so you need to integrate GA4 with an affiliate platform or use custom scripts.
- The free version of GA4 uses data sampling when processing large datasets, which may skew web tracking metrics.
- The free version of GA4 stores user-level and event-level data for only 14 months, which limits historical analytics, so you have to export data to BigQuery or use an affiliate platform with longer retention.
The good news is that anyone looking for an advanced solution can use Phonexa, an eight-in-one performance & affiliate marketing ecosystem that helps track, distribute, and analyze lead flows in real-time and historically, while costing pennies compared to solutions like Adobe.
“One thing many people forget to do is implement real-time tracking. They often say, ‘Okay, I’ll review this once a month,’ and then realize, ‘Wow, this isn’t going well.’ That’s usually because their system doesn’t track data in real time, or it’s too difficult to access the stats quickly. So, first and foremost, consolidate everything into one place, allowing you to monitor performance through a simple, streamlined process. Make sure your decision-makers and media buying team have access to the right data.” – David Pickard, CEO at Phonexa |
As a GA4 user, you can leverage GA4’s free analytics and Phonexa’s advanced affiliate tracking capabilities to address GA4’s free tier disadvantages and only pay for what you actually use.
