What Affiliate Marketing Actually Is
The Basic Mechanic
When a retailer like Backcountry or Suunto wants to drive sales, they open up an affiliate program. Publishers, that's you, get a unique tracking link. When someone clicks your link and buys something, the retailer pays you a commission. No inventory, no customer service, no upfront cost. You just need the link and an audience that trusts you.
The Cookie Window
Here's the part most guides don't know about: You don't just earn on the exact product your client clicked. Most affiliate programs set a cookie window, typically 15 to 60 days, during which you earn credit for anything that customer buys from that retailer. Clicking on your affiliate link activates a “session cookie,” so if a client clicks your sleeping bag link and ends up buying a tent, boot liners, and a hydration pack in the same session, you earn on all of it.
What you don't have to do
You don't handle payments, returns, shipping, or customer questions. The retailer manages all of that. Your job is just to point people to products you already believe in. Everything else is handled.
How GearBook Plugs Into This
Your SubID
Every GearBook guide is assigned a unique SubID, a short identifier (usually your name slug, like john-smith) that gets appended to every affiliate link in your catalog. When a client clicks through and buys, the sale is tied back to your SubID. That's how we know exactly what you earned each month. You never have to touch the links, we build them with your SubID already baked in and paste them directly into your catalog.
What Counts as a Qualifying Sale
A qualifying sale is any purchase made within the cookie window after a click from your catalog link. The product doesn't have to be one you listed, it just has to come from the same retailer within the window. So a client who clicks your crampons link and ends up buying a full kit is a great day for your earnings tab.
How commissions get to you
Affiliate networks report sales on a delay, typically 30 to 60 days after the transaction clears (to account for returns). We pull your numbers from the network dashboard each month, calculate your cut, and send payment to whatever PayPal or Venmo handle you have on file. You can always see your payout history in your guide dashboard.
The Math, In Plain Terms
The commission rates vary by retailer, Backcountry pays around 8%, Suunto runs up to 10% on GPS watches. Other retailers are less while some are more. GearBook takes a small platform margin so we can stay operational, and passes the rest to you Here's what that looks like in practice.
A Realistic Single-Client Scenario
A client clicks your Mammut Barryvox S2 avalanche beacon recommendation ($599), but also picks up a probe and shovel in the same session. This could bring the total cart to roughly $700. At 5% net commission, that's $35 from one client, one click, one cookie window. Multiply that across a season of clients who trust your recommendations, and it becomes a meaningful number.
High-AOV Specialties
Average order value (AOV) varies a lot by specialty. Ski and alpine guides tend to see the highest carts as their clients are buying technical gear (crampons, ice axes, skis, boots) with $400–$700+ price tags. Even on the lower end, the commissions are real, plus your clients might be more willing to buy your favorite screwgate carabiner rather than a whole splitboard setup. The key is volume of referrals, not chasing single big purchases.
Three Things You Can Do This Week
You don't need to understand affiliate marketing inside-and-out to start earning from it. But a few small moves now make a real difference over a season.
Catalog Link in Bio
It sounds obvious, but it's the single highest-leverage thing you can do. Your bio is the first place a potential client looks after finding your page. One link. That's all it takes to turn a follower into a commission.
Confirmation Emails
If you send any kind of booking confirmation (you should if you don't already!), pre-trip info, or gear list to clients, add your catalog link at the bottom. Something as simple as "Check out the gear I recommend for this trip:" followed by your link. Clients who are already paying for you and the experience you curate are exactly the audience you want clicking through.
The QR Code Card
Your GearBook dashboard has a button that generates a QR code card you can download or print. Hand one out at the end of a course, leave a stack at a gear shop you're affiliated with, or stick one on the back of a business card. The QR code goes straight to your catalog - no link required.
