A Guide to Building an Affiliate Program for Your Weight Loss Brand on Shopify

In the weight loss industry, authenticity review matters more than anything else.

People often listen to a fitness coach who shares their daily routine. They follow a blogger who documents their honest weight loss journey.

Or, they trust a recommendation from a friend who has actually used the product and seen results.

These are not sales pitches, they are real stories from real people, and that is what builds genuine trust.

So how can you get these people to promote your products?

This is when affiliate marketing becomes your suitable tool. It is all about building partnerships with these authentic voices.

An affiliate program allows you to have your products recommended by people your customers already listen to and respect.

This guide will walk you through launching, managing, and growing a weight loss affiliate program from scratch.

Planning the foundation of your affiliate program

A successful affiliate program starts with a strong foundation from the beginning. You must have the right assistant tool, an attractive commission, and a fair cookie duration.

Choosing the right affiliate management app

Managing an affiliate program manually is a path to problems.

It can be easy at first, but it quickly becomes more about paperwork than about growth.

You have to track every link by hand, calculate each commission one by one, and risk making payment errors that can damage trust with your partners.

This manual work is a huge burden that takes time away from building relationships and improving your program.

You don’t want to face these issues, so a dedicated affiliate management app is what you need.

For weight loss Shopify brands, UpPromote is a top-recommended affiliate solution that solves all the heavy lifting.

The app tracks every click and sale automatically within a single dashboard, so you know the data is always accurate.

Plus, our system calculates commissions instantly and simplifies the payout process, saving you hours of work each month.

Moreover, UpPromote has different affiliate recruitment tools to help you find new partners and scale your program effectively.

You can test out all of these amazing features at no risk with our 14-day free trial. This applies to all available plans, so you can know which one suits you most before committing.

Designing a competitive commission structure

An attractive commission rate can easily drive high-quality affiliates to your affiliate program.

It’s not hard to set up the right commission structure. You need to make it clear about the product types and follow the industry trends as well.

To save you time, we’ve researched over 105 Shopify weight loss brands to find out some common patterns.

If your Shopify weight loss store offers subscription-based meal plans, it’s better to set a fixed commission rate. 

You can adjust the rate within this range based on production cost and delivery fee.

For example, Diet-to-go offers a $50 commission on every successful diet meal plan subscription.

Meanwhile, Noom offers a $10 commission on each of their weight loss program sign-up.

For weight loss supplements, the ideal rate lies between 10% and 20%. 

These products often come with high prices ($150-400), so a high commission is reasonable.

Plus, this rate is fair enough for affiliates’ effort while making your affiliate program stand out in the industry.

Finally, weight loss tracking apps and programs often go with a 10% to 15% commission. 

These digital downloads cost no shipping fees or manufacturing costs. So, even if you set a 15% commission on each sale, your final profits will not be affected too much.

For example, a $50 weight loss program with a 10% commission means affiliates earn $5 for each download.

Imagine if they bring around 30 downloads per month, they can easily get $150.

Setting a fair cookie duration

The cookie duration decides how long you give an affiliate credit for a sale after someone clicks their link.

A fair cookie duration shows affiliates that you respect their work, because most customers do not buy products the first time they see them.

When setting up this period, you need to match the cookie life to how your customers actually make decisions.

The time it takes someone to buy a supplement is very different from the time it takes to commit to a new diet plan.

For low-consideration products: 15-30 Days

Almost all the types of weight loss supplements are quick and easy to purchase.

This is often true for simple, repeat-buy items where the customer already knows what they want.

So, for these types of fast decisions, a standard cookie duration of 15 to 30 days is fair and makes sense.

For example, Maximum Slim sets a 30-day cookie duration on their dietary supplements.

For high-consideration products: 45-60 Days

The time it takes to commit to a new diet plan is much longer than buying a supplement.

Customers need time to do their research, read reviews, and compare their options before they feel ready to submit a new plan.

A short cookie duration would unfairly rob the affiliate of their commission.

That is why a longer period of 45 to 60 days can work better here.

For example, Diet-to-go offers a 45-day cookie duration on their subscription-based meal plans.

For high-investment solutions: 90 Days

Finally, no one subscribes to a 6-month fitness course within a short consideration.

These are serious and long-term investments, so they need to save up, wait for the right time in their life to start, or even consult their doctor.

For these major commitments, a 90-day cookie duration is a suitable period.

You can see top center like Ace Fitness also set this long cookie duration on their certified weight loss programs.

Recruiting high-quality affiliates for your weight loss affiliate program

Having the right affiliates to promote your weight loss products can significantly boost sales over time.

They are not the ones who have many followers. They are the ones who know the weight loss world and have a dedicated audience.

We’ll help you identify your ideal affiliates and how to connect with them successfully.

Identifying your ideal affiliate partners

Weight loss affiliates are actually easier to find than you think. They are commonly health professionals, creators, and top voices within the community.

First, you should partner with certified professionals for expert promotional content.

These people are nutritionists, dietitians, and personal trainers whose recommendations are backed by science.

They can write detailed reviews about your supplements on their blog post.

Or, they post a video on their personal social account to share about how your meal replacement shake works for a post-workout routine.

If you’re looking for affiliates with more diverse content, we suggest working with YouTubers and Instagram influencers. 

They often share their own personal weight loss journeys.

For example, they can sometimes feature your snacks in a “What I Eat in a Day” Instagram Story and tag your brands.

Plus, they can feature your product in their top 5 best weight loss products and give honest reviews, like @Dr. Westin Childs.

After watching his videos, the viewers can click on the product link right under the video descriptions and are likely to purchase.

Finally, you should consider partnering with the top active members of the weight loss community.

They run supportive Facebook groups or online forums.

Their influence is built on a foundation of peer-to-peer trust within a safe community.

So, they promote in a more subtle and organic way, often by answering a member’s question with a helpful suggestion.

You should join these communities and participate in discussions actively. It’s a great way to reach these top members and naturally offer a collaboration.

Reaching out to your desired affiliates effectively

Knowing your ideal weight loss partners is just the first step.

The next big challenge is how to reach out and offer them collaboration successfully.

1. Connecting with your desired affiliates manually

Inviting high-quality affiliates needs time and effort. You should focus on making a real connection with a few ideal partners to show your dedication.

First, you need to find them. Think about where your customers go for advice.

You can start with a simple Google search for things like “best keto snack reviews” or “weight loss journey blog”

You can also dive into social media, searching hashtags like #weightlossjourney or #ketolife on Instagram and TikTok to find creators with engaged audiences.

Once you have a list of potential partners, the most important step is how you reach out. Take five minutes to read their latest blog post or watch their newest video.

Then, you should craft a personal email that mentions something specific you enjoyed.

This proves you’re a real person who values their work, not just a robot sending spam.

Here’s what that looks like:

2. Turning customers into your best affiliates

Another advocate that you should turn into is your loyal customers.

These are people who have already spent their own money on your products and love them.

Their recommendations are pure gold because they’re 100% genuine.

It’s simple to ask them to join your program with UpPromote Customer Referral.

They don’t have to fill out a long registration form and wait for approval.

You can set up a widget on your website to prompt customers to join your program.

Then, your customer only needs to fill in their email address to join the referral link. Our system will automatically provide them with a unique referral link to start promoting.

If they successfully introduce your products and bring in sales, they’ll get commission from that purchase.

Empowering affiliates for your Shopify brand’s long-term success

Affiliates can put more effort into bringing more sales if they get enough marketing assets and rewards fairly.

Equipping them with a professional media kit

The number one rule of working with affiliates is to make their job easy.

You need to give them everything they need to succeed, from high-quality visual content to pre-written content.

Providing high-resolution images helps your affiliates increase their promotion quality.

A weight loss Shopify brand has to look clean and trustworthy, and the last thing you want is for an affiliate to pull a blurry image from your site.

Instead, we suggest handing them a folder of crisp product shots or vibrant lifestyle photos for their Instagram feeds.

Then, think about the words they use. It’s great that your affiliates already have pre-written content for their upcoming promotions.

Your partners are experts at connecting with their audience, but they aren’t compliance experts.

So, you can provide them with short and benefit-driven sentences that they can confidently use for captions or newsletters.

Plus, they don’t have to worry about making unverified claims while giving you peace of mind.

And for partners with a blog or website, ready-to-use banners are a must.

You should update these banners regularly.

It’s even better if the banners go along with the new product launch and upcoming campaigns to align all of their promotions.

With UpPromote Media Gallery, you can create one go-to spot for everything.

Then, affiliates only need to log in, grab exactly what they need, and get back to creating content that drives sales.

Keeping affiliates engaged and motivated

The real key to long-term success is keeping affiliates actively engaged and motivated to promote your brand.

There are two powerful ways to do this: rewarding long-term performance and creating short-term excitement.

Reward top affiliates with a tiered commission structure

Not all affiliates bring the same amount of sales, so you should reward each fairly for their performance.

And, a tiered commission structure is your great solution.

With the help of UpPromote, you can set up the tier based on their referrals, number of sales, and overall sales revenue.

Then, whenever affiliates achieve a qualified sales amount, they will be automatically upgraded to the next tier and earn a higher commission.

For example, your Shopify weight loss store sells diet supplements with a 10% commission on each sale.

You can set 3 levels like this to motivate affiliates:

• Tier 1 (0-50 sales): 10% commission
• Tier 2 (51-150 sales): 15% commission
• Tier 3 (151+ sales): 20% commission

Create excitement with performance bonuses and contests

While tiered commissions are great for long-term motivation, bonuses and contests are for stirring up affiliates quickly.

Performance bonuses are straightforward rewards for hitting a specific target.

With UpPromote, you can create a one-time, monthly, or quarterly bonus within a few steps.

For example, you could announce, “Any affiliate who sells 15 units of our new meal replacement shake this month will receive a $50 cash bonus.”

Then, if an affiliate reaches this amount, our system will automatically generate the bonus and credit to their affiliate account.

Conclusion

You now have the framework, it’s the right time to create a weight loss affiliate program.

But remember, this is more than just a marketing channel. A great affiliate program is a true partnership. It is built on trust, open communication, and the shared goal of helping people on their health journey.

Your journey will be easier with UpPromote since we’ve covered all the complex tasks. Let’s find out about our pricing plans to choose the best one.
