How to Choose the Best Affiliate Programs: 7 Criteria That Actually Matter

I've promoted everything from $5 earbuds to $2,000 online courses. Some programs turned into steady paychecks. Others wasted months of effort for pocket change.

The difference? I learned to evaluate affiliate programs before I ever wrote a word of content.

Most beginners do this backwards. They find a product, grab a link, and start creating. Then they wonder why nobody clicks — or why the few clicks they get don't convert.

Here's the truth: Not all affiliate programs are created equal. Some are goldmines. Others are traps designed to make the vendor rich while you do all the work.

In this guide, I'll walk you through the 7 criteria I use to evaluate every program before I promote it. These are the same criteria that helped me go from random $10 commissions to consistent four-figure months.

1. Commission Rate and Structure

Let's start with the obvious: how much do you get paid?

But it's not just about the percentage. A 50% commission on a $20 product is $10. A 10% commission on a $500 product is $50. The math matters.

Here's what I look for:

• Minimum viable commission: I won't promote anything under $20 per sale unless the conversion rate is insane (like 10%+)
• Recurring commissions: Monthly subscriptions are the holy grail. One sale can pay you for years
• Tiered structures: Some programs increase your rate as you drive more sales. That's free money for scaling

My sweet spot is programs offering 30-50% on products priced $100-$500, or recurring commissions on SaaS tools. That range gives you meaningful payouts without requiring massive traffic.

2. Cookie Duration

This is where beginners get burned.

A "cookie" is how the vendor tracks that your referral came from you. When someone clicks your link, a cookie gets stored in their browser. If they buy within the cookie duration, you get credit.

Here's the problem: most people don't buy on the first visit. They research. They compare. They think about it. If your cookie expires in 24 hours, you're losing most of your commissions.

Cookie durations vary wildly:

• Amazon: 24 hours (brutal, but the conversion rate makes up for it)
• Standard programs: 30-60 days
• Good programs: 90 days
• Great programs: Lifetime or "first referrer wins"

My rule: anything under 30 days needs an incredible conversion rate to be worth my time. I prefer 60+ days, and lifetime cookies are a massive bonus.

3. Product Quality and Reputation

This one should be obvious, but I see people ignore it constantly.

If you promote garbage, three things happen:

1. Your audience stops trusting you
2. Refunds eat your commissions
3. Chargebacks can get you banned from the program

Before I promote anything, I:

• Buy and use the product myself (when possible)
• Read real user reviews on Reddit, Trustpilot, and social media
• Check refund rates if the vendor shares them
• Look at the vendor's history — have they been around, or do they launch and disappear?

One bad promotion can damage your reputation for months. One great product can create loyal fans who buy everything you recommend.

It's not worth the quick buck.

4. Conversion Rate and EPC

EPC stands for "Earnings Per Click." It tells you how much the average affiliate earns for every person they send to the sales page.

Here's why it matters more than commission rate:

Program A pays 50% on a $100 product. Sounds great. But the sales page converts at 0.5%. Your EPC is $0.25.

Program B pays 20% on a $200 product. Lower percentage. But the sales page converts at 3%. Your EPC is $1.20.

Program B earns you almost 5x more per visitor. Same traffic, way more money.

Most affiliate networks (like JVZoo, WarriorPlus, ClickBank) show EPC data publicly. Use it. A program with a $2+ EPC and solid gravity score is usually a winner.

5. Marketing Materials and Support

The best affiliate programs don't just give you a link and wish you luck. They give you tools to succeed.

Here's what I expect from a quality program:

• Email swipes: Pre-written emails I can customize for my list
• Banner ads: Multiple sizes and styles for different placements
• Review access: Free or discounted product access so I can create honest content
• Affiliate manager: Someone I can contact with questions or for custom deals
• Launch calendar: Advance notice of promotions so I can plan content

Programs that invest in their affiliates get better results. It's that simple. If a vendor treats affiliates like an afterthought, their program probably performs like one.

My favorite programs send me updates, share what's working for top affiliates, and even offer exclusive bonuses I can give my audience. That makes my job easier and my promotions more effective.

6. Payment Terms and Reliability

I've been stiffed by vendors. It's not fun.

Payment terms to check before you promote:

• Minimum payout: Some programs won't pay until you hit $100 or more. Fine if you're driving volume, frustrating if you're starting out
• Payment schedule: Net-30 is standard. Net-60 is annoying but common. Net-90 is a red flag
• Payment methods: PayPal, wire, Payoneer, crypto — make sure they pay how you want to be paid
• Hold periods: Some programs hold your first payment for 60+ days to verify legitimacy

Also check the vendor's reputation for paying on time. Search "[vendor name] affiliate payment" and see what comes up. Forums like Warrior Forum and affiliate Facebook groups are goldmines for this intel.

I once promoted a product that generated $800 in commissions. The vendor went silent for 90 days, then claimed "technical issues." I eventually got paid, but the stress wasn't worth it. Now I check payment reputation before I send a single click.

7. Competition and Saturation

This is the criteria most beginners overlook — and it's crucial.

A great program with 500 super affiliates all promoting the same keywords is a bloodbath. You'll spend months creating content and never rank.

Here's how I evaluate competition:

• Search the product name + "review": If the first page is dominated by major sites with massive domain authority, it's probably too competitive for a new site
• Check YouTube: Are there 100+ review videos? Or just a handful?
• Look at the affiliate leaderboard: If the same 3 people always win, the program might be dominated by a small group
• Check launch dates: Newer products have less competition but more risk. Established products have proven demand but more content saturation

My strategy: I look for programs in the "sweet spot" — proven products with decent demand but not so much competition that I can't get traction. Often that's a product with 20-50 review videos and a few blog posts, but room for a fresh perspective.

Sometimes I also look for angles nobody's covering. Everyone reviews the main product? I'll create content about the upsells, the alternatives, or how it compares to a specific competitor.

My Top Affiliate Program Picks for 2026

Based on these criteria, here are programs I'm actively promoting right now:

Program	Commission	Cookie	Why I Like It
ConvertKit	30% recurring	90 days	Great product, loyal users, pays for years
SiteGround	$50-$100/sale	60 days	High conversion, everyone needs hosting
Semrush	$200/sale + 40% recurring	120 days	Huge payouts, SEO audience loves it
Teachable	30% recurring	90 days	Course creators stick around, good LTV
JVZoo/WarriorPlus	Varies (often 50%+)	Lifetime	Instant commissions, tons of products

These aren't the only good programs out there, but they all score well on my 7 criteria. Start here, then branch out as you learn what works for your audience.

Your Action Plan

Don't just read this and move on. Do this right now:

1. Audit your current programs. Run them through these 7 criteria. Drop anything that scores poorly on 3+ criteria
2. Pick 2-3 new programs to test. Use the table above as a starting point
3. Request review access. Most vendors will give you free or discounted access if you have a real platform
4. Create one piece of content for each. A review, a comparison, or a tutorial — whatever fits your audience
5. Track your EPC for 30 days. Double down on what works, cut what doesn't

Affiliate marketing isn't about promoting everything. It's about finding the right programs and promoting them well.

These 7 criteria will save you months of frustration and help you focus on what actually moves the needle.
