Point Spar at your storefront and get back a graded diagnosis
The audit scores your store against a library of conversion rules and reads your GA4, Microsoft Clarity, and customer reviews, then returns a ranked list of the gaps costing you the most. Every other thing Spar does starts from this diagnosis.

How the diagnosis comes together
Spar crawls the store and checks it against the rules library, then pulls in four evidence sources. It merges everything into one set of gaps, so a finding from your reviews and a slow, inaccessible product page land on the same ranked list instead of in separate reports.

Every finding shows its working
A gap is not a hunch. Each one carries the rule it failed, the behavior signals that back it up, and an estimate of what fixing it is worth, so you can see why it ranked where it did before you spend a sprint on it.
Checkout forces shoppers to create an account before paying

Evidence behind this gap

A rules library built for ecommerce conversion
The library is organized by area of the store, and each area holds dozens of specific rules with the research behind them. Spar runs the rules that fit each page type, so a product page is checked against product-page rules and your cart against cart rules.
