LVL 02The challenge

Great parts, hard to find online.

Their old WooCommerce site was slow, buggy and had no way to search for parts. Customers called instead of buying online, and every order tied up the phone.

No part search

No way to search by vehicle, and confusing menus. Customers couldn't tell which parts fit their car.

Lost sales at checkout

Slow pages, bugs and a clunky checkout made people give up, which also wasted SEO and ad traffic.

Hard to add products

Adding or updating products took too long, which slowed down growth and marketing.

LVL 03What we built

Find the right part in three clicks.

classic-mopar-parts.com
01

Search by year, make and model

Pick your car and see only the parts that fit. No guessing, no phone call needed.

02

A shorter path to checkout

Clear product pages, simple filters and a faster checkout, laid out for how people actually shop.

03

Easy to manage

The team can add products, update prices and track sales without calling a developer.

LVL 04On the phone

Over half their shoppers are on a phone.

01

Designed for phones first

The vehicle search, menus and checkout were laid out for small screens, then scaled up.

02

Fast on any connection

Pages are built ahead of time and served from a global network, so they load quickly anywhere.

03

Accessible to everyone

Launched fully ADA compliant, so every customer can find and buy parts.

LVL 05Results

More sales from day one.

Faster pages, an easier search and a smoother checkout paid off the first month and kept growing.
