When choosing between Serpstat vs Keysearch for your affiliate promotions, you're comparing two of the market's most popular SEO software tools. Both offer recurring commissions, accessible approval processes, and solid earning potential for publishers in the content marketing, blogging, and digital marketing niches.
This guide breaks down the key differences to help you decide which program fits your audience and income goals.
Commission Comparison
Structure Overview
| Metric | Serpstat | Keysearch |
|---|---|---|
| Commission Rate | 35% recurring | 35% recurring |
| Payment Model | Recurring (monthly) | Recurring (monthly) |
| Minimum Payout | Typically $10–$20 | Typically $10–$20 |
| Payment Frequency | Monthly | Monthly |
Real-World Earnings Scenario: 1,000 Clicks/Month
Assuming a 3–5% conversion rate (typical for SEO tool affiliate traffic):
30–50 conversions × $20–$50 avg. subscription = $600–$2,500/month baseline
With 35% recurring commission:
- Month 1 earnings: $210–$875
- Month 6 earnings: $1,260–$5,250 (if 60% retention)
- Month 12 earnings: $1,680–$8,750 (if 70% retention)
Key insight: Both programs have identical commission rates, so your earning potential is equal. The difference lies in how many conversions you'll generate based on cookie window and audience fit.

Cookie Window: 90 Days (Serpstat) vs. 30 Days (Keysearch)
What the Cookie Window Means
A cookie window is the timeframe during which a visitor's action is credited to you as the referring publisher. Once the window closes, subsequent conversions aren't attributed to your referral.
Serpstat: 90-Day Window
Advantages:
- Users who compare tools over weeks still credit your referral
- Captures readers who bookmark and return later
- Higher attribution rate for high-involvement purchase decisions
Best for: Technical audiences, enterprise buyers, researchers who evaluate multiple tools
Keysearch: 30-Day Window
Advantages:
- Faster feedback loop—you know within a month if traffic converts
- Standard in SaaS affiliate programs
- Still captures most immediate purchase intent
Best for: Content marketing audiences with faster decision cycles
Earnings Impact
For a publisher driving 1,000 monthly clicks:
- Serpstat's 90-day window may capture 15–25% more conversions from delayed decision-makers
- Keysearch's 30-day window misses some indirect conversions but aligns with typical content marketing buyer journeys
Advantage: Serpstat (longer window = higher commission potential)

Network & Reliability
Both programs operate in-house affiliate networks (not managed by third-party platforms like Impact or ShareASale), meaning:
Tracking & Accuracy

|---|---|---|
| Tracking Technology | First-party cookies + UTM parameters | First-party cookies + UTM parameters |
| Fraud Detection | Standard | Standard |
| Real-Time Reporting | Yes | Yes |
| API Access | Limited | Limited |
Payout Consistency
- Serpstat: Known for reliable monthly payouts; established affiliate program since ~2016
- Keysearch: Growing affiliate program; generally consistent payouts but younger program
Reliability verdict: Both are solid. Serpstat has a slight edge due to program maturity, but Keysearch shows no red flags.

FAQ
1. Which program has higher conversion rates?
Answer: Data is sparse, but anecdotal reports suggest Keysearch may convert slightly higher for beginner-focused content (3–6% vs. 2–4% for Serpstat). However, Serpstat's 90-day window often compensates, resulting in similar overall earnings. Test both if possible.
2. Can I promote both Serpstat and Keysearch?
Answer: Yes. Most affiliate programs permit cross-promotion. In fact, promoting both allows you to:
- Recommend Serpstat to advanced SEOs
- Recommend Keysearch to beginners
- Capture a wider audience
Just disclose your affiliate relationship and ensure recommendations are honest.
3. What's the average earnings potential from each program?
Answer: Based on typical publisher data:
- Serpstat: $500–$3,000/month (for 2,000–5,000 monthly clicks with 3–5% conversion)
- Keysearch: $400–$2,500/month (for 2,000–5,000 monthly clicks with 3–5% conversion)
Earnings depend more on traffic quality and audience alignment than the program itself. High-intent traffic converts 2–3x better than generic traffic.
