How YouTube Affiliate Marketing Works
You join an affiliate program, receive a unique tracking link, and include it in your video description. When a viewer clicks your link and makes a purchase within the cookie window (typically 24–90 days), you earn a commission. Commissions range from 1–3% on physical goods to 20–40% on software subscriptions — making SaaS affiliate programs the highest-value for most creators.

Where to Place Affiliate Links for Maximum Conversions
- Video description — first 2 lines (visible without 'show more' click) get 5–8× more clicks than buried links
- Pinned comment — the top comment on your video, pinned by you, gets read by most commenters
- End screen or card — direct verbal CTA at the video's end pointing to the link below
- Chapter marker descriptions — if you mention a product in a specific chapter, add the link to that chapter's timestamp description
- Bio link tool (Linktree or native YouTube handle page) — for traffic from non-YouTube sources
Disclosure Is Non-Negotiable
FTC guidelines require you to disclose affiliate relationships every time you use an affiliate link — in the video, in the description, and in any social media post. The disclosure must be clear, conspicuous, and not buried in fine print. Non-disclosure risks FTC action and YouTube demonetization.
How to Pick Affiliate Products That Convert
Promote products you have personally used and would recommend even without a commission. Your conversion rate will be 3–10× higher for genuine recommendations vs. paid promotions your audience can detect. The highest-converting affiliate videos are honest comparisons ('I tried X and Y for 30 days — here's which I kept') — not promotional overviews.
