How do Product Review Apps Affect Your Shopify Site Speed?

Product review apps remain some of the most popular apps in eCommerce. However, before you install a product review app on your store, it is crucial to consider the impact of these apps on your site speed. This is what our research aims to do.

You need every help you can get to ensure your Shopify store does well, and customer reviews help greatly.

Think of it this way; customer reviews can make or break any business. The number of scam sites and fake information increases daily, so it's no surprise that customers are now more cautious. In fact, the biggest fear when shopping online is "what if I get scammed?"

By collecting and showcasing reviews on your eCommerce store, you build trust with your customers, and these reviews act as a form of social proof. 

Choosing the right app that won't affect your store speed with many different product review apps on Shopify might be tricky. We have curated some of the best product review apps to help you find product review apps that won't affect your store speed. 

Why are Product Reviews Important?

One great way to reassure customers of your store's authenticity is by showing them product reviews from other customers. 

Why are product reviews so important? Instead of telling you, why don't we show you? 

Picture this, imagine you're a customer looking to buy, let's say, a pair of socks, and once you Google "shoe stores", a large number of results pop up. The next step becomes the issue of trust; all these stores might claim to have precisely what you need, but how do you know if they do. 

This is where product reviews come in. Product reviews simply say, "Hey! Other customers have bought this item, and here's what they have to say about it." Think of it as an assurance, telling customers all you need to know about your store, its products and services based on other customers' experiences.

What We Did

Apps generally impact store speed, which is why care must be taken when adding apps to Shopify stores. To help you identify great product reviews apps, we found the best product reviews apps using forums, Google results, community discussions, and app ratings.

Our first step was to create a level playing field for our tests. We created 7 demo stores, customized them with identical homepages and products. Next, we installed 10 apps on each store, including: 

  • Automizely Page Builder
  • Google 
  • Oberlo
  • One-Click Upsell
  • Printiful 
  • Privy 
  • Push Owl
  • ReConvert 
  • SEO Optimizer 
  • Shopify Email 

Once done, we ran speed tests on each store using Google's Pagespeed Insights and recorded the results. 

To ensure accuracy, we double checked each store’s speed score multiple times. 

Next, we created live duplicates of each store's theme and installed one product review app/store on the duplicate’s product theme. Finally, we ran speed tests on the duplicate themes to see the impact these apps had on the store's speed. 

Our results show just how much these apps without the reviews affect your site speed once installed. In the next few weeks, we’ll show you how much each product review app affects your store speed. 

STORE 1: YOTPO PRODUCT REVIEWS & PHOTOS

On the first demo store, we installed the Yotpo Product Reviews and Photos app. With a 4.9 star rating on the Shopify app store, Yotpo includes a one-click feature that allows you to collect reviews for multiple products with just one click.

Our Results 

Just like any other Shopify app, product reviews app in some way affects store speed. Whether it is by dropping the speed score one or two numbers down, these apps may begin to clog up a store's speed in the long run. 

Apps are well-known speed killers, and it doesn't take long for merchants to start seeing the negative impact of these apps on their store speed. One product review app is fine on any store, but when other apps are added, some of which may be duplicated, they eventually become a problem that requires a major fix. 

When this happens, you'll need to hire an expert Shopify site speed optimization agency like EcomExperts. 

Conclusion

These apps live up to their Shopify ratings; not surprisingly, they are a good fit for Shopify merchants looking to add product reviews to their store.
