How an Instagram CRO Experiment Lifted Sales by Double Digits for One eCommerce Website

In this case study, we’re explaining how adding user generated content (UGC) in strategic places on an eCommerce site can increase your conversion rate.

We know from working with hundreds of eCommerce brands that they are always looking for the best ways to utilize user generated content (UGC). In this case study, we are sharing a few tests we ran for Mountain Housean eCommerce business that sells freeze-dried foods for hikers, hunters, and camping enthusiastsshowing how adding UGC in strategic places on an eCommerce site can increase the conversion rate.  

Specifically, we curated and displayed photos on the main category pages, which lead to a conversion rate lift of 13%.

In this post, we are sharing what we learned in the process including:

  • The psychology of why this worked.
  • How to leverage UGC content and social media to improve conversion rates.
  • How you can apply these learnings in your eCommerce business.

To see your best possible conversion rate, you need an advanced strategy designed for your specific audience, and we can help. If you’d like our CRO experts to see what conversion best practices can be applied to your eCommerce site, contact us here.

About the Mountain House Instagram Contest CRO Test

An important part of having UGC work for increasing conversion rate is the quality of the photos. eCommerce brands should think of their user generated content strategy similar to their own product photography. High-quality photos will increase desire for the product and likely, the conversion rate.

So for Mountain House, instead of pulling random UGC photos, we chose stunning images that capture customers’ attention from a contest that Mountain House ran on their Instagram profile.

Mountain House has cultivated a loyal and large brand following with more than 45,000 followers on Instagram. They ran a contest collecting UGC photos from loyal customers and Instagrammers in the summer of 2017. This conceptalong with the AB test we ranput the best content on the category pages and exceeded all expectations.


Variation: 13% lift  

Specifically, we curated and added awesome contest photos to category pages as a value add to drive home that people buy and love these products (as shown above).

We used ReadyPulse to curate and pull in these images dynamically. We did it by category and specifically pulled out our favorite ones for this test. We looked for unique places and customers doing cool things, and not just your typical “I’m holding the product in front of a door photo.” That’s not engaging.

Because Mountain House has a diverse customer base comprised of camping and hiking enthusiasts, outdoor adventure seekers and preppers, this contest helped to reinforce the brand perception of one of their key customer segments: everyday people who go hiking and hunting on the weekendsand how they love consuming these products.  

And, the customers who got their photos featured feel special. They feel like the brand recognizes them, which builds more brand loyalty, and then they are more likely to keep buying the products.

How to Incentivize Your Customers to Create Compelling UGC Content

UGC content works well when you tap into your most engaged customers on social channels, and then give them a reason to get excited to share content with you.

You need to incentivize them by empathizing with them and understanding their motivations.  

In this example, we needed to be able to give credit to them in a way that gets them the “notoriety” that they’re looking for. This means having a prize that motivates people to want to engage. In this case, it was a year’s supply of freeze-dried food.

Location of UGC Matters: Don’t Just Test UGC in One Place and Declare It a Success or Failure  

Since the homepage is the page that almost everybody lands on, and probably gets the most traffic, it is a natural place to run CRO tests for the first time.

However, we often see brands quick to call something a success or failure after only testing it on the homepage for a short time. That’s not always going to be the spot with the most significant impact.

Our CRO tests with Mountain House prove that. We first did a test on their homepage. This was the original test. It was less impactful, and it only resulted in a small lift.

Then, we tested it further down the funnel. We added it on every single category page. The category pages are where it resonated with visitors. No matter where people navigated to, they saw it.

You can also test adding UGC on product pages. For example, if you’ve got only a handful of products or you’ve got a huge Instagram base, putting it on the product page is definitely something worth trying.

We wouldn’t recommend adding it on ‘add to cart’ and ‘checkout’ pages though, because you don’t want to push people to your Instagram page and further away from completing a purchase.

This UGC strategy can work well with any brand that has visually captivating products and a large concentration of social influencers. For example, this could also work well if you sell juicing products.  

Leveraging Social Proof to Generate More Sales

The underlying reason why this worked so well is that it shows real people using their products in real life. This may seem obvious, but few eCommerce businesses leverage this social proof effectively.

In addition, it is easy to underestimate the power of social media platforms. Everybody thinks of social media as something that people interact with, but only some companies understand how it can affect their conversion rate. This clearly proves that this kind of content from social media can be used strategically on your site to achieve the latter.

If you have a strong brand and a social following with engaged users, you can use UGC content like Instagram posts to increase your conversion rate.

Don’t throw social media channels to the wayside just because you think it’s only for GenZ and millennials and won’t ultimately influence purchasing decisions.


While this UGC campaign worked well for Mountain House, every site is different. It’s helpful to benchmark your results against the best in class sites.

Every year, our CRO experts evaluate 25 top sites through our 154-point matrix, which breaks down the most important eCommerce features.

Inflow eCommerce Best-in-Class Research Study 2019

You might notice that our yearly Best-in-Class Research Study for 2019 looks a lot different from the Best-in-Class study from 2018. What’s the big change? In 2019, you can’t be “Best-in-Class” if you have major discrepancies between your desktop and mobile site. This year’s report combines mobile and desktop into a single 154-point matrix breaking

You might notice that our yearly Best-in-Class Research Study for 2019 looks a lot different from the Best-in-Class study from 2018.

What’s the big change?

In 2019, you can’t be “Best-in-Class” if you have major discrepancies between your desktop and mobile site.

This year’s report combines mobile and desktop into a single 154-point matrix breaking down the most important features an eCommerce site should have in 2019.

2019 Matrix Screenshot

Our matrix this year is mobile first: since Google now uses mobile as its first priority to index and rank your site, so do we. If your eCommerce site has a feature on desktop but not mobile, you didn’t get a full “yes” rating from us.

In 2019, users engage brands, not websites. Your cross-device experience needs to be consistent. That’s why the 2019 Best-in-Class Matrix reflects total web presence, with priority now given to the mobile experience.

Previous Years:

What’s New in eCommerce and the Best-in-Class Report in 2019?

Our “Best-in-Class” analysis starts by building a master list of the best eCommerce sites based on our experience, what we hear from clients, and even our opinions. We then assemble our expert panel to narrow the list for our review.

Since 2013, we’ve assembled our annual Best-in-Class matrix by having our conversion rate optimization (CRO) team survey these sites, feature-by-feature, giving a “yes” or “no” rating to each one. Then we use these metrics to evaluate the latest trends among the top eCommerce sites.

In previous years, our matrix included 20 examples from desktop sites as well as 20 eCommerce sites on mobile. While there would be some overlap, we still compiled two separate lists.

For 2019, we’ve combined them into one. That means a few sites have fallen off our list, including and BrasNThings.comand you’ll see a few reasons why later.

That brought the total number down to 25. That meant some cuts. But some new sites with strong mobile presence also entered the list, including:

What We Changed in 2019

We conducted most of this year’s analysis on mobile devices, then validated them on desktop. In previous years, we split these two variables on separate tables. Now, to receive our “yes” in any given feature category, your eCommerce feature has to be present in both.

But that’s not the only change in 2019. We’ve also made the following improvements:

Reorganizing categories.

We’ve updated our category structure so you can view important elements like Trust or Customer Support in aggregate. Previously, we went “Page-by-Page” with each eCommerce sitethe checkout page, the home page, etc.

Now we group our features by distinct themes so they’re easier for you to browse.

Increasing detail.

In our 2018 matrix, we included a single row for “Free Shipping”. That’s not enough.

Rather than ask if free shipping is merely available, we’ve gone a step further in 2019, including asking:

  • Does free shipping require your order to meet a certain dollar threshold?
  • Does the limit require membership?
  • Does a site offer free returns as well?

This helps expand on the quality of each feature, rather than simply denoting its presence.

Removing a few sites.

One prominent example of a site that fell off the list this year: Dolls Kill’s mobile site was not cohesive, missing a lot of the tools that aid in navigation in 2019. The entire site is built around the concept of “Dolls” as different style choices, however there are none to be found in navigation and they aren’t clearly messaged on the homepage or throughout the site either. Other elements like unintuitive product recommendations or missing the best practice of “0 in cart” suggested that DollsKill has fallen behind compared to other sites on the 2019 list. also lost a lot of features: no “0 in cart,” no category navigation, and issues with displaying sizing availability in their product gallery. The product pages are not optimal, with important selections and calls to action well below the fold. We also found bugs on their site such as formatting problems on the cart slide-out, broken images, and toggling items-per-row on mobile. That won’t cut it in 2019.

This year, the name of the game is mobile compatibility and function. If you didn’t have it, you weren’t included in our Best in Class list.

Top Emerging eCommerce Trends from the Past Year

In comparing 2019 to 2018, we spotted some interesting trends. You can download the full report to spot many of these trends for yourself. Below, you can see how many out of our 25 Best in Class eCommerce sites included the following features:

#1: Expanding on Basic Product Reviews

Product reviews are great social proof for any eCommerce company, but today’s user expects more. That’s especially true when your competition is utilizing the following variables:

  • Q&A elements. What have other users asked about this product before, and what do the answers tell you about the product quality?
  • “Showrooming.” In our “Help with Showrooming” row of the 2019 report, we asked whether the eCommerce site included details like how the product fits. What size is the pictured model is wearing? What are other users saying about the fit of the clothing? More of your competitors are offering this information than ever before, and customers find it valuable.

Best-in-Class eCommerce Sites with Showroom Features:

Total Yes: 16

Total No: 9

#2: Facilitating Navigation

You saw DollsKill and Bras N Things drop from the list, partially due to navigation issues. The increased emphasis on mobile users means that you have to facilitate what they’re looking for as they tap their phone:

Subcategory navigation is the big trend now.  We found that this is so common that nearly all of the Best-in-Class sites considered now offer some degree of subcategory navigation on mobile. That changed in a hurry, as less than half of the sites examined last year utilized subcategory navigation.

We also started tracking for a Mega Menu this year. (Note we are defining a mobile “mega menu” as the navigation functioning the same as desktop with the top categories across the top, and sub-category navigation dropping down when categories are selected.) Many of the sites still aren’t utilizing Mega Menus on mobile, even though this is an element we at Inflow have tested with success.

For example, Zappos created exceptional mobile navigation by incorporating both Mega Menus and Subcategory elements so you could bring up the following with only two taps:

Mega Menu:

Total Yes: 8

Total No: 17

#3: Mobile Parity

You’ve already heard about the importance of matching your mobile experience with your desktop. Let’s take one example that demonstrates why this might be important.

In Row 64 of the 2019 Matrix, you’ll notice we looked for the element of Swatches on the Gallery. This turned out to be a key flag for emerging mobile trends: while many sites have used this feature on desktop, we noticed that more eCommerce mobile sites are starting to catch up.

You can use an insight like this by following the best practices of a site like, which incorporates whole product images for each color swatch. demonstrated one of the top emerging trends all year: features previously available only on Desktop are moving to mobile.

This trend also demonstrates how important it is to incorporate your favorite desktop features into your mobile presence. There are still opportunities to stay ahead of even the Best-in-Class if you emphasize migrating your favorite desktop features over to the mobile side. Our conclusions lead us to recommend that any eCommerce brand does this as much as possible to stay ahead of the curve.

Swatches on the Gallery:

Total Yes: 13

Total No: 12

The Biggest Declining Trends in eCommerce

The Direct Path from Homepage to the Product Page

It’s not always necessary to create a direct path to a product page from the home page, especially if you have a large catalog in the first place.

If you compare the 2019 Matrix to the 2018 version, you’ll find the trend has waned a bit. The top eCommerce sites were constructing direct paths almost universally in 2018, while this year, they dropped closer to 50/50. In our experience testing this, a larger site or catalog will have more trouble putting the right products in front of the right people.

What should your site do? It’s something that needs testing on a case-by-case basis; you might want to reach out to us for more insights if you’re unsure what to make of this trend.

Direct Path from Home Page to Merchandise:

Total Yes: 14

Total No: 11

Video and 360 Product Views

Most sites in 2019 were content to offer static images. They’re easier to fill in as they’re cheap, they’re simple, and providing full video or 360-degree functionality can become prohibitively expensive as your product catalog grows.

This trend may also stem from the increased emphasis on mobile: the necessity of loading video on mobile can distract the customer and get in the way of the shopping experience. We found that 360-degree views on mobile were rare, just like last year. Meanwhile, 2019 saw fewer Best-in-Class sites incorporating product videos.

Video on Product Page:

Total Yes: 6

Total No: 19

360 Product Views on Product Page:

Total Yes: 1

Total No: 24

Social Promotion, Sharing, and Signing In

There was a surprising trend this year: people are more distrustful of social links and sign-ins. Perhaps this trend reflects what we’ve seen in younger demographics for some time now: some research suggests that 1 in 10 users have deleted their Facebook accounts, while a Pew Research survey put the number at about 1 in 4. Poor P.R. for platforms like Facebook have made people in the 18-29 demographic skeptical about social sharing and sign-ins.

Above: Social sign-ins can influence mobile trust even if users have their own account.

Lower trust for Facebook sign-ins can affect how mobile users see your brand. One thing we’ve found at Inflow is that if you show a trust seal that people already don’t trust, it will hurt your overall trust as well.

This means that even if you give users the option of a conventional log-in, you have to be wary of the effect of social promotions, sharing, and sign-ins.

Social Promotion:

Total Yes: 3

Total No: 22

Social Sharing:

Total Yes: 6

Total No: 19

Social Sign-Ins:

Total Yes: 4

Total No: 21

Trends to Watch and Test for Yourself

Image Zoom

The overall trend in image zoom in 2019 was similar to last year’s: most eCommerce sites let you zoom in on an image, even in their mobile presence. The temptation is to view this as a stagnant trend and lump it in with “360 view” and product videos as not as important on mobile.

That’s a mistake. Because users can’t feel the products, they need to be able to see detailing like stitching and the quality of materials. The ability to zoom in on an image won’t be cost-prohibitive like video or 360 view, but could give you a distinct advantage over other products, especially in specific categories like clothing.

Image Zoom:

Total Yes: 19

Total No: 6

Discount Pricing

How should you frame your discount: as a percentage or as a dollar total?

Our results in 2019 suggest that this needs to be tested in every case. The top eCommerce sites in our Best-in-Class Research Study were split down the middle. Whether you choose to display a percentage or a dollar total for your product discounts will depend on your business and how large the individual discounts are.

There is a lot of price psychology that goes into factoring in this variable. Before you make a decision, you’ll want to dive into the research Matrix for 2019 yourself and see what companies like yours are doing.

Stating Savings on Product Page:

Total Yes: 9

Total No: 15

Total N/A: 1

Final Pricing in the Shopping Cart

Free shipping continues to be a top trend in eCommerce sites, which ties into the concept of final pricing: the more simple you can keep your shopping cart experience for the customer, the better. The top eCommerce sites in our matrix tend to display final pricing in the cart so there are no surprises for their customers.

Final Pricing in the Shopping Cart:

Total Yes: 19

Total No: 6
