Click-Through Rate (CTR)
The percentage of readers who click your affiliate link out of all who see it.
What is Click-Through Rate (CTR)?
Click-through rate (CTR) is the percentage of people who click an affiliate link out of all who viewed the page or element containing it — clicks divided by impressions, expressed as a percentage.
Click-Through Rate (CTR) In Practice
CTR measures how effectively your content drives clicks to the merchant offer, but it is a diagnostic metric rather than an income metric — EPC is the complete income-per-visitor picture. A high CTR on a low-converting offer produces fewer commissions than a lower CTR on a perfectly matched one. CTR varies significantly by placement: in-text contextual links within relevant content produce 1%–3% CTR; banner ads average well below 1% in 2026 as banner blindness has intensified; dedicated CTA buttons within review content can reach 5%–10% for engaged readers. A healthy CTR benchmark for affiliate marketing in 2026 is 0.5%–1% for display placements and 2%–5% for in-text contextual links in review content. The two primary CTR diagnostics: low search-result CTR means improving your meta title and description; low in-content CTR means improving link placement, anchor text relevance, or CTA clarity.
Example of Click-Through Rate (CTR)
An affiliate review of GreenGeeks places three links: one in the introduction (CTR 0.8%), one in a comparison table (CTR 4.2%), and one as a CTA button in the conclusion (CTR 6.1%). The table and button generate most commissions despite the introduction receiving more impressions — because those placements match the reader's evaluation state. The affiliate tests adding a second CTA button mid-article at the point where readers have absorbed the core value proposition.
