Shoplift review

What Shoplift does

Shoplift is an A/B testing app built for Shopify. You install it from the Shopify App Store and it adds a small tracking script to your theme, so there's no code to paste by hand. Tests use Shopify's own building blocks. You duplicate a template or a whole theme, make changes in the Shopify Theme Editor, and Shoplift splits traffic between the original and the variant.

Test types

The docs list five test types. Template tests change one page type, such as the product page for a group of products. Theme tests change the whole store, including navigation and cart. URL redirect tests compare two separate pages. Price tests update the price shown on product pages, collection pages and in the cart, and Shoplift says the right price carries through to checkout. JavaScript API tests are for developers writing custom experiments. Price testing, subscription testing, campaigns and personalization sit on the Advanced plan.

Results and statistics

Shoplift tracks conversions server-side, collecting cart and order data directly from Shopify, and it credits orders to a variant even when the shopper buys days later on a return visit. Goals include revenue per visitor, add-to-cart, click rate and bounce rate. The pricing page describes the analysis as Bayesian and says it predicts how long a test needs, in real time. Core segments results by device. Advanced adds referral domain, channel, UTM and country.

Lift Assist

Lift Assist is the AI-assisted part, available on Advanced and Pro. It recommends tests, and when you pick one, it duplicates your template and inserts a matching theme section, such as a sticky cart, countdown timer or inventory indicator. It scans your store's colors and fonts to style those sections. You then review and edit the variant in the Theme Editor before it goes live.

Speed and flicker

Shoplift uses an anti-flicker script that briefly blanks the page while a test loads. It says this typically clears within 150 milliseconds, and that the app lowers Google's page speed score by about 2 to 4 points. For most stores that's a fair trade, but it's worth checking on your own theme.

Limits

It's Shopify only, and its FAQ says headless storefronts built with Hydrogen or Next.js aren't supported, because Shoplift relies on Shopify's theme system to inject tests. Plans are capped by total monthly store visitors, not just visitors in tests. Go over and your tests pause until you upgrade or the billing cycle resets. Core isn't offered above 100k monthly visitors, and one-click apply for winners is limited to stores under that size.

Who it suits

Shoplift fits Shopify brands on a standard theme that want steady, no-code testing of templates and themes, with revenue per visitor as the scoreboard. Brands whose main questions are about prices, shipping and offers may also want to look at Intelligems, and businesses off Shopify need a different tool altogether.
