FOR AUTOMOTIVE BRANDS

Automotive marketing built on the right fitment.

If you sell car parts or accessories on Shopify, almost every sale depends on fitment data, and since May 3, 2025, many imported parts have paid a new US duty. We clean up the fitment first, then build the year, make and model search and the Shopping campaigns that sell from it, with each category's budget set from what its parts cost to land now.

IN SHORT

Automotive ecommerce marketing is how a car parts or accessories brand sells online. Almost every sale depends on fitment data: the record of which years, makes and models each part fits.

HOW PEOPLE BUY
Vehicle first. Shoppers start from their year, make and model, often the trim too, then the part name or part number, and they want the fit confirmed before they order.
WHEN IT SELLS
Replacement parts sell all year, whenever something wears out, and the cars on US roads keep getting older: S&P Global Mobility put the average at 12.8 years in 2025. Accessories also sell as gifts before Father's Day and Christmas, and at Black Friday and Cyber Monday.
WHAT WINS THE SALE
A fit the shopper can trust: the part checked against their vehicle on the page, fitment written out in plain text, the part number they searched for and a reminder in the cart.
WHY AUTOMOTIVE IS DIFFERENT

If it might not fit, it won't sell.

Every part has to match the buyer's exact vehicle, and the catalog behind it can run to thousands of products. Both have to be right before ads pay off.

Shoppers who can't confirm the fit

If the page doesn't show which years, makes and models a part fits, buyers leave to double-check somewhere else. Some order anyway, get the wrong part and send it back.

HOW WE FIX IT A year, make and model search on your store

Messy fitment data

Supplier files often arrive with missing years, inconsistent names and part numbers in the wrong field. Every gap is a part that doesn't show up for the vehicles it fits.

HOW WE FIX IT Fitment and part numbers cleaned up

A catalog too big for one campaign

With thousands of parts in one Shopping campaign, Google tends to spend on a few best sellers while the rest barely show. You can't see which categories make money.

HOW WE FIX IT Shopping campaigns built for big catalogs

Searches that name the vehicle

People type the part and the vehicle together: 'Tacoma roof rack' or 'F-150 floor mats'. Without pages for the vehicles your customers drive, those searches go to bigger stores.

HOW WE FIX IT Pages for each make and model
INSIDE THE WORK

How a parts catalog turns into sales.

Three things decide whether a parts store sells: fitment data you can trust, a store that confirms the fit, and campaigns and pages built for searches that name the vehicle or the part number.

FITMENT DATA

Clean fitment data comes before any ad.

Every part has to say which vehicles it fits, and that information usually starts in a supplier file, often in the industry's ACES and PIES formats. By the time it reaches a Shopify store, the file often has missing years, makes spelled several ways and part numbers stuck in the title. Each gap is a part that won't show up for a vehicle it fits.

So we fix the data before we spend on ads. Years become ranges, each make and model gets one spelling, and trims and positions (front, rear, left, right) get their own fields. Part numbers move to their own field too: the MPN, or manufacturer part number, which Google uses to identify each product. The result is one clean catalog in Shopify, and every vehicle search, Shopping ad and email draws on it. More in product feeds.

  • Years, makes, models and trims in consistent fields
  • Part numbers in their own field, where Google looks for them
  • One clean catalog behind the store, the ads and the emails

VEHICLE SEARCH

Shoppers pick their vehicle once, then see only what fits.

A parts shopper's first question is 'will this fit my truck?' If the store can't answer it, they leave to check somewhere else, or they guess, order the wrong part and send it back. With thousands of products, browsing by category isn't enough either: someone looking for floor mats doesn't want to scroll past mats for every other vehicle.

So the store gets a year, make and model selector in the header and on every collection. The shopper picks their vehicle once, and from then on sees only the parts that fit. Each product page checks the part against that vehicle and lists every fitment in plain text, with the part number. The cart repeats which vehicle the order is for. We build it as part of Shopify development.

  • A year, make and model selector on every page
  • A fit check on every product page
  • Return reasons tracked by part, so the data behind them gets fixed

PART SEARCHES

The searches that sell name the vehicle or the part number.

The searches that turn into orders tend to be specific: '2021 F-150 floor mats', or a part number copied off the old part. The people typing them know exactly what they need. To show up, your Shopping titles have to lead with the part, then the brand, the part number and the main vehicles it fits, and your store needs a page for each vehicle your customers drive.

Then the catalog is split so Google doesn't spend it all on a few best sellers. Shopping campaigns are grouped by category, brand and margin, so budget reaches the rest of the catalog too, and you can see which categories make money. Margins moved in 2025, since many imported parts have paid a new US duty from May 3, so each category's target is reset from what its parts cost to land now. Collection pages for popular makes and models, like 'Silverado bed accessories', target the searches that name the vehicle. See how we run Google Ads and SEO.

  • Shopping titles that lead with the part, brand, part number and vehicle
  • Campaigns split by category, brand and margin
  • A collection page for each popular make and model

WHAT'S INCLUDED

From fitment data to the checkout.

We fix the product data first, because every ad, search result and page depends on it.

  1. Year, make and model search

    A vehicle selector in the header and on every collection. Shoppers pick their vehicle once and see only the parts that fit.

  2. Fitment on every product page

    Each part lists the years, makes, models and trims it fits in plain text. The page also checks it against the vehicle the shopper picked.

  3. Clean catalog data

    Supplier data turned into consistent titles, part numbers, specs and fitment across the whole catalog.

  4. Shopping by category and margin

    Campaigns split by category, brand and margin. Budget then reaches more than a few best sellers.

  5. Pages for popular vehicles

    Collection pages for the makes and models your customers drive. Each targets searches like 'Silverado bed accessories'.

  6. Email matched to the vehicle

    Customers tagged with the vehicle they bought for. New parts, reminders and offers then match their car or truck.

For a parts or accessories brand, it runs the marketing that sells online: fitment and product data, Shopping and search ads, SEO and email. A good one sets budgets by category margin, because floor mats and a turbo kit can't share one ad target.

If your parts fit only certain vehicles, yes. Shoppers expect to choose their vehicle and see only what fits. Without that, they go elsewhere to check the fit, and some never come back.

Lead with the part, then the brand, the part number and the main vehicles it fits. One part can fit dozens of models, so put the full fitment list in your product data and on the page.

Yes, mostly for things people want rather than parts they need. Show lighting, interior upgrades, wheels and truck gear on a real vehicle in a short video. Replacement parts usually sell better through search, because people are already looking for them.

Make the fit hard to miss: a vehicle check on every product page, fitment notes in plain words and a reminder in the cart. Then track return reasons by part, and fix the data behind the ones that come back most.

They change the margin by category. Many imported parts have paid a new US duty since May 3, 2025, so a category that was worth advertising before may not be now. Reset each category's ad target from today's landed cost, and move budget toward the parts with margin left, such as your own brand or parts the duty doesn't cover.
