Affiliate Marketing

Affiliate marketing is a purely performance-based acquisition channel where a business pays external partners (affiliates) a commission for generating specific, measurable actions (usually sales or leads). It fundamentally shifts the risk of marketing spend away from the brand and onto the partner, functioning as a variable cost rather than fixed advertising overhead.

The Trap

The biggest trap is paying out commissions for 'coupon poaching.' If a user is already on your checkout page and opens a new tab to search for 'Promo Codes,' an affiliate ranking for that search term will capture the cookie and take a commission for a sale you had already organically won.

What to Do

Implement strict terms and conditions for your affiliate network. Ban 'brand bidding' (where affiliates buy paid ads against your company name) and implement a multi-touch attribution model or at least a strict 'first-click' vs 'last-click' policy depending on whether you want affiliates to drive new discovery or close existing intent.

In Practice

Wirecutter (acquired by The New York Times) built a massive media empire entirely monetized by affiliate marketing. Instead of running display ads, they wrote definitive, trustworthy product reviews. When a reader clicked their link and bought a TV on Amazon, Wirecutter took a 1-10% commission.

Pro Tips

01
A tiered commission structure is highly effective: offer a base 10% commission, and bump it to 15% once an affiliate generates 50 sales a month. This incentivizes your best partners to push your product over competitors.
02
Your affiliate program is only as good as the marketing assets you provide. Give partners pre-written swipe copy, high-res banners, and custom landing pages.
03
B2B SaaS companies should offer recurring commissions (e.g., 20% for the first 12 months) rather than just a one-time bounty, aligning the affiliate with customer retention.

Decision scenario

The Bidding War

You run a software company selling a $100/mo subscription. You recently launched an affiliate program paying $50 per signup. Within a month, signups spike by 20%, and you are thrilled. However, your paid search manager notices something alarming.

Google Ad Costs

Spiking 40%

Decision 1

Your paid search manager reports that the Cost-Per-Click (CPC) on your own brand name ('YourApp Pricing') has doubled. They investigate and find two of your top affiliates are running Google Ads bidding on your brand name to intercept high-intent searchers and claim the $50 commission.

Let them do it. Their ads are bringing in signups, and paying a $50 commission is cheaper than your normal $80 customer acquisition cost (CAC).Reveal

You are cannabilizing your own organic and paid traffic. The affiliates aren't generating new demand; they are just stepping in front of people who already decided to buy your product. Because they are bidding against your own internal marketing team in the Google Ads auction, they drive up your CPC. You end up paying $50 out of pocket for a customer you would have gotten for free via an organic brand search.

True Acquisition Cost: Massively inflatedIncremental Revenue: Zero

Immediately update your affiliate Terms & Conditions to strictly ban 'Brand Bidding' and terminate the two affiliates, reversing their pending commissions.Reveal

Correct. Affiliate programs should ONLY reward incremental growth. A good affiliate brings a customer who otherwise would never have heard of your company (e.g., via a software review blog). By blocking brand bidding, your internal CPC drops back to normal, and you stop paying $50 bounties for your own organic traffic.
