How to Track Affiliate Link Clicks by Country, Device, and Source (YouTube + Blog)

Amazon Associates does not break down your affiliate clicks by country, device, or traffic source. You get aggregate clicks and ordered items per Tracking ID — that is it. No country column, no mobile vs. desktop split, no referrer showing whether a click came from your YouTube video or your blog post. This means you cannot see that 40% of your audience is clicking from the UK, landing on Amazon US, and earning you nothing.

TL;DR: To track affiliate link clicks by country, device, and source, you need either a custom Google Analytics 4 setup (limited to your own site’s outbound clicks) or a smart link tool with built-in per-link analytics. Smart links are the cleaner solution for YouTube creators because they capture country, device, and referrer data at redirect time — including clicks from YouTube descriptions that GA4 cannot see.

Most creators discover this gap the hard way. You check your Amazon Associates dashboard, see a decent click count, but the conversion rate is suspiciously low. You suspect international traffic is the culprit, but there is no way to confirm it inside Associates Central. The data you need to diagnose the problem simply does not exist in Amazon’s reporting. Here is how to get it.

The Tracking Gap: What Amazon Associates Actually Shows You

Amazon Associates gives you three data points per Tracking ID: clicks, ordered items, and revenue. That is the entire picture. There is no geographic breakdown, no device type filter, no referrer source column.

This matters more than most creators realize. If you have a global YouTube audience — and most channels do — a significant percentage of your affiliate clicks are from viewers outside your home country. Those viewers click your US Amazon link, land on a storefront where they cannot buy (or where their Prime membership does not apply), and leave. You earn zero commission on those clicks. But in your Associates dashboard, they still show up as clicks with no corresponding orders, dragging your conversion rate down and giving you no insight into why.

The same blindspot applies to device data. You cannot tell whether your clicks are 70% mobile or 70% desktop. This matters because mobile users who land in a browser instead of the Amazon app convert at significantly lower rates. Without device data, you cannot make the decision to enable deep linking — because you do not know the problem exists.

Other affiliate programs vary. Impact.com, a partnership management platform used by brands like Walmart and Target, and ShareASale offer slightly more granular reporting, but country-level click breakdowns are still limited or require custom report building. The consistent theme across affiliate networks: they track conversions well, but click-level analytics are an afterthought.

Method 1: Google Analytics 4 for Source and Device Tracking

GA4 can track affiliate link clicks by country, device, and source — but only for clicks that originate on a website you control. If you run a blog alongside your YouTube channel, GA4 is a viable option for your blog traffic.

Here is the setup:

Enable Enhanced Measurement in your GA4 property. Go to Admin > Data Streams > your web stream > Enhanced Measurement. Toggle on “Outbound clicks.” GA4 will now fire a click event whenever someone clicks a link that leaves your domain.
Create a custom event scoped to affiliate link domains. In GA4, go to Configure > Events > Create Event. Set a condition like event_name equals click AND link_url contains amazon.com (repeat for other affiliate programs). Name it something like affiliate_click.
Build an Exploration report. Go to Explore > Free Form. Add dimensions: Source/Medium, Device Category, Country. Add your affiliate_click metric. Now you can see which traffic sources drive affiliate clicks and from which countries and devices.

This works. But it has two significant limitations.

The YouTube Referrer Problem

YouTube’s mobile app strips referrer headers when users tap links in video descriptions. When a viewer on their phone taps your affiliate link in a YouTube description, GA4 either records the referrer as youtube.com (inconsistently) or as (direct) — with no way to distinguish between the two.

The practical impact: GA4 undercounts YouTube-sourced affiliate clicks on mobile by an estimated 30-50%. You can mitigate this with UTM parameters (?utm_source=youtube&utm_medium=description&utm_content=video-slug), but Amazon strips UTM parameters from the final URL before it reaches their system. The UTMs help GA4 attribute the outbound click, but Amazon’s own reporting still cannot correlate the commission back to a specific video.

What GA4 Cannot Tell You

GA4 tracks clicks on pages you own. If the affiliate link lives in a YouTube description, a Discord server, an email newsletter, or a social media bio — anywhere that is not your website — GA4 sees nothing. Zero data.

For creators whose primary affiliate distribution channel is YouTube descriptions (which is most of you), GA4 is blind to the majority of your affiliate clicks. Country and device data in GA4 describe your website visitors, not your YouTube audience.

Method 2: UTM Parameters for Blog and Email Traffic

For affiliate links placed on your blog or in email newsletters, UTM parameters are the standard tracking method. Append parameters to your affiliate URLs following a consistent naming convention:

https://www.amazon.com/dp/B0EXAMPLE/?tag=yourtag-20&utm_source=blog&utm_medium=post&utm_content=best-keyboards-logitech

The key parameters:

utm_source: Where the click originates (blog, email, youtube)
utm_medium: The content type (post, newsletter, description)
utm_content: The specific piece of content (best-keyboards-review, march-newsletter)

This gives you clean source attribution in GA4 for clicks leaving your site. But there is a critical caveat for Amazon affiliates: Amazon strips UTM parameters before the destination URL resolves. Your GA4 will correctly attribute the outbound click to a blog post, but Amazon Associates cannot connect that click to a commission.

Combining Tracking IDs with UTMs

The most complete setup for Amazon affiliates uses both: unique Tracking IDs per content type plus UTMs on outbound links from your own site.

Create separate Amazon Tracking IDs like yourbrand-yt-20 for YouTube, yourbrand-blog-20 for blog posts, and yourbrand-email-20 for newsletters. This gives you commission-level data by channel directly in Associates Central. Add UTMs to blog and email links for click-level source data in GA4.

The remaining gap: neither system shows you country or device breakdowns. You know your blog earns more commissions than YouTube (via Tracking IDs), but you cannot see that your blog’s UK traffic is converting at zero or that 68% of your YouTube clicks are mobile.

Track Affiliate Link Clicks by Country and Device with Smart Links

Smart links are the cleanest solution for creators who want country, device, and referrer data without building GA4 custom reports or managing multiple Tracking IDs. Each smart link has its own analytics dashboard that records every click with three dimensions:

Country — determined via IP geolocation at redirect time
Device type — mobile, desktop, or tablet, parsed from the user agent
Referrer — the domain the click originated from (youtube.com, google.com, your blog domain, or direct)

The workflow takes about 2 minutes: paste your affiliate URL into Youfiliate, a smart links platform that turns affiliate links into geo-targeted, analytics-enabled short URLs for YouTube creators. You get a branded youfil.to short URL. Use that link in your YouTube descriptions, blog posts, emails — everywhere. Check the per-link dashboard to see exactly where your clicks come from.

No GA4 configuration. No Google Tag Manager. No custom events or Exploration reports.

YouTube vs. Blog Comparison: The Smart Link Method

The specific question most creators ask is: “Are my YouTube videos or my blog posts driving more affiliate sales?” Smart links answer this two ways.

Approach 1: Separate links per platform. Create two smart links for the same product — one for your YouTube description, one for your blog post. Compare their dashboards side by side. You will see total clicks, country distribution, and device split for each platform independently. This is the approach I recommend if you want clean, unambiguous data. For more on per-video attribution specifically, see our guide on tracking affiliate clicks per YouTube video.

Approach 2: One link, filter by referrer. Use a single smart link everywhere and filter the referrer column in the dashboard. Clicks showing youtube.com as the referrer came from YouTube. Clicks showing your blog domain came from your blog. Youfiliate captures the referrer at redirect time — before the browser transition to the affiliate program — which is more reliable than GA4’s outbound click referrer tracking, especially for YouTube mobile traffic.

What the Device Breakdown Actually Tells You

Device data is not just trivia. It drives two specific decisions:

Deep linking. If 65-70% of your affiliate clicks are mobile, you should enable deep linking so those clicks open the Amazon app (or merchant app) instead of the mobile browser. App users convert at higher rates because they are already logged in with payment methods saved. Without device data, you would never know to make this switch.
Content formatting. If your blog drives mostly desktop traffic but your YouTube drives mostly mobile, you should promote different products in each channel — desktop-friendly products with complex comparison pages for the blog, impulse-buy products with simple app checkout flows for YouTube.

Country data is equally actionable — which brings us to the real payoff.

The International Traffic Problem: Where Most Creators Lose Money

International viewers landing on the wrong Amazon storefront do not convert — and without country-level click data, you cannot see how much revenue that gap is costing you.

Those international viewers see prices in a foreign currency, shipping that does not apply to them, and a checkout flow disconnected from their Prime membership. They leave. You earn nothing. And until you have country-level click data, you cannot quantify the scale of this problem.

Smart links solve both sides: the analytics show you the country distribution, and geo-routing rules redirect international clicks to the correct local storefront. A viewer in Germany gets sent to Amazon.de. A viewer in Japan gets sent to Amazon.co.jp. Same link, same YouTube description — no extra work on your end.

This is the gap that separates smart link tools from GA4-based tracking. GA4 can tell you that clicks are coming from the UK. It cannot route those clicks to Amazon UK. You need a separate tool for routing, and at that point, you should use the tool that handles both analytics and routing in one place.

Tool Comparison: Your Options at a Glance

Here is how the main options for tracking affiliate link clicks by country and device compare side by side.

Tool	Country Data	Device Data	Referrer Data	Geo-Routing	Deep Linking	Pricing
Amazon Associates	No	No	No	No	No	Free
GA4 + UTMs	Via custom reports	Via custom reports	Partial (YouTube gaps)	No	No	Free
Geniuslink	Yes	Yes	Yes	Yes	Yes	Per-click ($6/mo base + $2/1K clicks)
Youfiliate	Yes	Yes	Yes	Yes	Yes	Flat rate ($9-$49/mo)

The pricing difference matters at scale. At 30,000 clicks per month, Geniuslink, a per-click smart link service, costs roughly $66/month. Youfiliate’s Growth plan covers unlimited clicks at $19/month flat. The analytics are comparable; the cost structure is not.

Frequently Asked Questions

Does Amazon Associates show affiliate clicks by country or device?

No. Amazon Associates shows aggregate clicks, ordered items, and revenue per Tracking ID. It does not break down clicks by country, device type, or referrer source. To get country or device data on your affiliate clicks, you need either a Google Analytics 4 custom setup (limited to clicks on your own website) or a smart link tool like Geniuslink or Youfiliate that logs click-level data at redirect time.

How do I see whether my YouTube videos or blog posts drive more affiliate clicks?

Create separate smart links for each platform and compare their dashboards. If you use one link across both, filter by referrer in your smart link analytics — YouTube-sourced clicks show youtube.com as the referrer. GA4 can track blog-sourced outbound clicks reliably, but it misses a significant portion of YouTube description clicks on mobile because the YouTube app strips referrer headers.

How do I track affiliate clicks by country?

Use a smart link tool with geo-analytics. Both Geniuslink and Youfiliate record each visitor’s country at redirect time using IP geolocation. Every click is logged with its country code, and you can view the breakdown in a per-link dashboard. GA4 can report outbound clicks by country for traffic on your own site, but it cannot track country data for clicks originating from YouTube descriptions, social media bios, or email links.

Why do my GA4 affiliate click numbers look lower than expected from YouTube?

GA4 misses most YouTube description clicks because it can only record clicks that pass through a page you control — for links placed directly in YouTube descriptions, GA4 sees nothing. YouTube’s mobile app also strips referrer headers when users tap links in video descriptions, so even clicks GA4 does catch from YouTube are often attributed to (direct) rather than youtube.com. Smart links solve this because the redirect passes through your tracked short URL before the user reaches the affiliate program, capturing the click regardless of where it originated.

Is Geniuslink the only tool that shows affiliate click data by country and device?

No. Youfiliate, a smart links platform for YouTube creators, offers the same per-link analytics — country, device, and referrer breakdowns — at a flat monthly rate. Geniuslink charges per click ($6/month base + $2 per 1,000 clicks), which adds up quickly for high-traffic channels. Youfiliate’s Growth plan covers 200 smart links with unlimited clicks for $19/month.

Can I track affiliate clicks from YouTube descriptions without Google Analytics?

Yes. Smart link tools track clicks independently of GA4. When you replace a raw affiliate URL in your YouTube description with a smart link (like a youfil.to short URL), every click passes through the smart link’s redirect server, which logs the country, device, and referrer before forwarding to the affiliate destination. No analytics code, no tag manager, no website required.

Start Tracking What Actually Matters

Aggregate click counts do not tell you where your affiliate revenue is leaking. Country, device, and source data do. Once you can see that a third of your clicks come from outside your home country and convert at zero, or that mobile users are bouncing because they land in a browser instead of the app, you can fix those problems — and the fix often means a meaningful jump in commissions without creating a single new piece of content.

If you want per-link analytics with country, device, and referrer breakdowns — plus geo-routing that turns international clicks into actual commissions — Youfiliate gives you both in one tool. Start free with 10 smart links at Youfiliate.com.
