More Conversions with Ecommerce Cart Cache (New in WooCommerce NitroPack Plugin)

Last updated on Sep 13th, 2023 | 4 min

It’s no secret online shoppers (and especially the ones on mobile devices) have soaring expectations when it comes to site speed.

In fact, speed has become one of the top factors for eCom businesses’ success.

Currently, retail sites that load in 2 seconds have shoppers visiting 8.9 more pages! In turn, 9.1% more visitors will add items to their cart and ultimately come back to shop again.

  • Seamless browsing
  • High customer satisfaction

Enter, the newest asset to the NitroPack plugin in WooCommerce – ECommerce Cart Cache. A minor optimization tweak with a big payout!

What is ECommerce Cart Cache?

ECommerce Cart Cache is a new caching feature that enables fast browsing in a WooCommerce store with items in the cart.

Usually, when you add items to a cart, this translates into a variable element near the cart icon.

From a site speed perspective, this means a page needs to load the variable element for every subsequent page you visit during your browsing session. That way, you know your items are still in the cart.

However, when a site doesn’t use a similar Cart Caching solution, you’ll experience a significant decrease in page loading speed.

It happens because the online store is unable to serve standard optimized cached versions of the pages you browse. And if it did that, you would see an empty cart (when, in fact, it isn’t).

Let’s see how Cart Cache solves this speed issue for WooCommerce stores.

How does ECommerce Cart Cache work?

By default, NitroPack stores cached versions of your original pages and serves them whenever a visitor loads a page on your site.

Thanks to WooCommerce’s sophisticated cache-ready cart, our ECommerce Cart Cache feature enables you to continue serving the same standard cached versions of your web pages to visitors regardless of added items.

This helps you provide a fast shopping experience and bump up customer satisfaction along the buyer’s journey.

Higher conversion rates with ECommerce Cart Cache

In online shopping, a visitor’s willingness to buy directly correlates to speed.

For retail sites, every 0.1s faster loading speed means 8.4% increase in conversion rate. That’s a huge improvement!

On the contrary, a one-second delay in page response results in a 7% reduction in conversions. 

Nonetheless, “Add to cart” doesn’t mean a “Successful purchase”. Using the ECommerce Cart Cache feature ensures your store:

  • Offers seamless shopping experience;
  • Kindles the shopping urge;
  • Motivates buyers to browse for more items;
  • Keeps visitors happy and inclined to hit “Checkout”.

Here’s what this means for your KPIs:

  • More time spent on page
  • Decreased bounce rates
  • Higher conversion rates
  • Increased average purchase value

Moreover, websites with great loading speed are rewarded by Google as well! The more seconds you shave off the shopping journey, the greater results you can expect in terms of cache hit rate, user experience, and search rankings.
