# Linktree vs Captions.ai: Which Affiliate Program Should Publishers Choose?

Choosing the right affiliate program is critical to your earning potential. If you're deciding between Linktree vs Captions.ai, this comprehensive comparison will guide you through commission structures, cookie windows, approval processes, and audience fit to help you make an informed decision.

Both platforms are digital tools that solve different problems—Linktree is a link-in-bio aggregator, while Captions.ai provides AI-powered video captioning. But as affiliate programs, they operate quite differently. Let's break down everything you need to know.

Commission Comparison

Linktree: 50% Recurring Commission

Linktree pays 50% of monthly recurring revenue (MRR) for the lifetime of each customer you refer. Here's what this means in practice:

• Customer subscribes to Linktree Pro ($5/month)
• You earn: $2.50/month, recurring
• Over 12 months: $30 per customer
• With 100 conversions in month one: $250/month in ongoing commissions

Captions.ai: 30% Recurring Commission

Captions.ai offers 30% recurring commission on subscription plans. Typical pricing starts around $10/month:

• Customer subscribes to Captions.ai plan ($10/month)
• You earn: $3/month, recurring
• Over 12 months: $36 per customer
• With 100 conversions in month one: $300/month in ongoing commissions

The Real Numbers: 1,000 Clicks/Month Scenario

Assuming a typical 5% conversion rate for affiliate traffic:

However, as your referrals compound:

• Linktree at 12 months (600 cumulative referrals): ~$1,500/month recurring
• Captions.ai at 12 months (600 cumulative referrals): ~$1,800/month recurring

Winner: Captions.ai for per-customer value; Linktree for velocity and market size.

The advantage shifts to Linktree because its higher commission percentage and massive addressable market typically yield more referrals—meaning your portfolio grows faster, even if the per-unit commission is lower.

Cookie Window

Linktree: 30-Day Cookie Window

A 30-day cookie window means:

• Affiliate credit applies if a user clicks your link and signs up within 30 days
• Effective for impulse purchases or immediate sign-ups
• Shorter tracking period can result in missed conversions if buyers take longer to decide

Impact: Publishers lose credit if prospects bookmark and return after 30 days.

Captions.ai: 60-Day Cookie Window

A 60-day cookie window means:

• Affiliate credit applies if a user clicks your link and signs up within 60 days
• Covers longer research and evaluation phases
• Better for high-consideration purchases where buyers need time to test free trials

Impact: Publishers capture more conversions when prospects evaluate the tool over several weeks.

Which Matters More?

For link-in-bio tools (Linktree), purchases are typically quick—users see the tool, understand its value, and subscribe. The 30-day window is sufficient.

For video captioning tools (Captions.ai), creators may test the free version, compare features, and consult teammates before upgrading. The 60-day window gives you a material advantage in conversion attribution.

Advantage: Captions.ai — the extended window better reflects natural buying behavior for SaaS tools.

Network & Reliability

Linktree: In-House Infrastructure

Linktree manages its own affiliate tracking and payouts:

• Tracking accuracy: Direct server-to-server integration reduces third-party tracking errors
• Payout consistency: Direct payment processing; typically pays via Stripe or wire transfer
• Transparency: Monthly dashboard shows conversions, commissions, and payouts clearly
• Fraud prevention: Built-in controls to prevent bot or invalid traffic

Reliability rating: ⭐⭐⭐⭐ (Industry-leading for SaaS)

Captions.ai: In-House Infrastructure

Captions.ai also operates its own affiliate backend:

• Tracking accuracy: Direct integration; consistent with Linktree's approach
• Payout consistency: Reliable monthly payouts; processed reliably but with smaller volume oversight
• Transparency: Solid affiliate dashboard with standard metrics
• Support: Responsive affiliate management team

Reliability rating: ⭐⭐⭐⭐ (Solid, though smaller scale than Linktree)

Difference: Linktree's larger scale and established infrastructure provide marginally better reliability. However, both programs are dependable for tracking and payouts. No significant edge here, but Linktree's maturity is a minor advantage.
