Google Analytics
The free analytics platform affiliates use to see which content drives traffic and affiliate clicks.
What is Google Analytics?
Google Analytics is a free web analytics platform — now Google Analytics 4 (GA4) — that tracks visitor behavior on a website, providing affiliates with traffic source data, engagement metrics, and, when configured with custom events, affiliate link click data.
Importance of Google Analytics
Google Analytics is the primary site-level analytics tool for content affiliates — it answers questions the affiliate network dashboard cannot: where did my visitors come from, which pages drive affiliate link clicks, how long are visitors engaging with my content, and which traffic sources produce the highest engagement before the merchant click. Without GA4, an affiliate knows their commissions but cannot connect them to specific traffic sources or content pieces — making optimization decisions largely guesswork.
Google Analytics In Practice
GA4 differs from its predecessor Universal Analytics in three important ways for affiliates. First, GA4 uses event-based measurement — affiliate link clicks must be configured as custom events and do not appear automatically. Second, GA4 replaced bounce rate with 'engagement rate' (sessions with at least one engagement event lasting over 10 seconds), which more accurately reflects review content quality. Third, GA4's attribution defaults to data-driven attribution rather than last-click. The three most important GA4 configurations for affiliates: set up outbound affiliate link click events via Google Tag Manager; apply UTM parameters to all off-site links so GA4 attributes traffic by campaign and channel; use Exploration reports to compare traffic volume, engagement time, and click rates across individual content pieces. GA4 data must always be cross-referenced with the affiliate network dashboard — GA4 shows traffic and on-site behavior; the dashboard shows conversions and commissions.
Google Analytics Best Practices
- →Configure affiliate link click tracking as custom events via Google Tag Manager — without this, GA4 shows traffic and engagement but cannot tell you which pages generate affiliate clicks or at what rate from each traffic source.
- →Apply UTM parameters to every link distributed outside your site so GA4 correctly attributes which off-site channels drive traffic to which content, enabling cross-reference with affiliate commission data from the same period.
- →Use GA4 Exploration reports to build a content performance view: top-traffic pages sorted by affiliate click event rate isolates which articles are best converting traffic to merchant clicks.
- →Monitor organic search sessions in GA4 alongside Google Search Console — if organic sessions to an article drop while impressions stay steady, click-through rate on the search listing has declined and the meta title or description needs updating.
- →Never use GA4 data alone for program allocation decisions — GA4 shows on-site behavior; the affiliate dashboard with Sub-IDs shows what that behavior converts to. Both layers together create the full attribution picture.
Example of Google Analytics
An affiliate configures affiliate link click tracking in GA4 for their Moosend review. After 90 days: 1,840 sessions, 312 affiliate click events (17% click rate), average engagement time 4 minutes 12 seconds. Email newsletter sessions: 71 clicks, 9 commissions — 12.7% conversion rate. Organic search sessions: 219 clicks, 11 commissions — 5.0% conversion rate. GA4 reveals email drives fewer clicks but converts at 2.5x the rate of organic search — a finding invisible without custom event tracking and UTM-attributed traffic segmentation.

Frequently Asked Questions
How do I use Google Analytics for affiliate marketing?
Configure GA4 with three customisations: (1) Set up affiliate link click events via Google Tag Manager so you can see which pages generate clicks and at what rate. (2) Apply UTM parameters to all links shared outside your site so GA4 correctly attributes traffic by channel and campaign. (3) Use Exploration reports to compare traffic, engagement time, and click rates across your content. Cross-reference GA4 traffic data with affiliate network commission data for full attribution.
What is the difference between Google Analytics and my affiliate network dashboard?
They measure different stages of the journey. Google Analytics tracks what happens on your site — traffic source, pages viewed, engagement time, and affiliate link clicks (if configured). Your affiliate network dashboard tracks what happens after the click — conversions, commissions, and reversals. You need both: GA4 for traffic attribution and on-site behavior; the dashboard for conversion and income data. Neither alone gives the complete picture.
Does GA4 automatically track affiliate link clicks?
No. Outbound affiliate link clicks must be configured as custom events. The standard approach: use Google Tag Manager to create a trigger for outbound clicks on merchant domains, send those clicks to GA4 as custom events with the destination URL as a parameter. Without this, GA4 shows traffic and engagement for your content but cannot tell you whether visitors clicked your affiliate links or which placement they used.
