Auto parts buyers shop with a vehicle or an old part in front of them. A home mechanic knows the year, make, model and engine. A repair shop has a part number from the box or the casting. Both want the same answers fast: will this fit, what condition is it in, and what happens if it does not work out. Used-parts buyers add a few more questions. Is that the actual part in the photo? How many miles were on the vehicle it came from? Is there a core to send back?
Common problems on auto parts websites
- Guessed fitment. “Fits most models” or a long list copied from another listing. When it is wrong, the part comes back, usually at your cost.
- Titles stuffed with vehicles. A title that lists twenty models is hard to read and looks like spam to a search engine.
- Part numbers that match only one way. The site stores “12-3456”, the buyer types “123456”, and the search comes back empty.
- Stock photos on used parts. A buyer of a used door wants to see that door, scratches and all.
- Cores hidden in the fine print. The core charge shows up at checkout or later, and the buyer feels tricked.
- Return rules that skip the real cases. Electrical parts, installed parts, special orders and cores each need a clear rule.
- One page per vehicle. The same caliper listed forty times, once per vehicle, makes forty thin pages that compete with each other.
What we build for auto parts sellers
- Fitment from real data, and only real data. The fitment list on a part comes from data you already have: eBay’s compatibility list for that listing, a supplier’s fitment file, or your own records. If a part has no fitment data, the page says so and asks the buyer to match the part number. We never fill the gap with a guess.
- Part-number search that forgives formatting. “12-3456”, “123456” and “12 3456” find the same part. Where your data carries OEM or interchange numbers, those are searchable too, and they show on the page as cross-references only when they come from a real source.
- Product titles in one steady pattern. The title carries the part, the position, the part number, the condition and the main vehicle when there is one, such as “Front Left Brake Caliper, Part 12-3456, Remanufactured”. The full vehicle list goes in the fitment table below.
- Condition you can see. New, used and remanufactured are separate conditions with a filter, and used parts get photos of the actual part and a written condition note.
- Core charges in plain view. The core charge sits next to the price, with how to send the old part back and how long the buyer has. How the charge is collected at checkout is decided with you during planning.
- Returns that cover the real cases. Your return policy, with the rules for electrical parts, installed parts and cores spelled out, appears on every product page.
- Categories by vehicle system. For example, Body / Doors / Door Handles / Exterior Door Handles, plus brand pages for each OEM and aftermarket brand you carry, and filters by brand, category, condition and price.
- Shipping by address and weight. Shipping is priced from the buyer’s address and the part’s weight. Hoods, bumpers and transmissions get their own rules, set with you, including local pickup.
- A staff order screen and alerts. Pullers and packers see orders and mark them shipped without the owner’s login, and new orders and questions arrive by email or Discord.
If you also sell on eBay, the store can stay in step with your listings. Our page for eBay and surplus parts sellers covers selling in both places, and our page on the scheduled eBay sync explains how listings stay matched.
Getting found for part and vehicle searches
Parts buyers type exact searches. A few typical ones:
- “2016 silverado driver door handle”
- “remanufactured front brake caliper f150”
- “used tailgate 2014 ram 1500”
- a bare part number with nothing else
Searches like these reward pages that state the part, the vehicle and the number plainly. Each part gets its own address and a clear title. Category pages such as Exterior Door Handles get a short introduction. Product structured data carries the brand, the part number, the condition, the price and whether it is in stock, and the sitemap includes every part, so Google and Bing can reach the whole catalog. Once you connect Merchant Center, a product feed can list the parts in Google’s free shopping results. Our guide to structuring a big parts catalog shows how categories, brand pages and product pages support each other.
Buyers also ask AI assistants which part fits their vehicle. An assistant can only repeat what it can read, so pages with real part numbers and real fitment tables give it something accurate to work with. We cannot promise a ranking or a mention in an AI answer. Our job is to make each part page clear and keep it that way through SEO and AI visibility work.
What we need from you
- Where your parts live today. eBay, an inventory system, a yard management program or a spreadsheet, and how fitment is stored in it.
- Photos. Photos of the actual part for used stock; for new parts, the brand’s images where you are allowed to use them.
- Your core policy. Which parts carry a core charge, the amount for each type, how long buyers have to return the core and what condition it must be in.
- Your return and warranty terms. Including how you handle electrical parts and installed parts.
- Shipping details. Typical weights, which items are pickup only, and which carriers you use.
- A payment account under your own business. You set it up; we connect it and test checkout.
The platform caps a store at 50,000 products, and hidden products count toward that; our note on catalog size limits explains how we plan around it. After each import, we match the part count to your source and spot-check a random handful of parts against it.
Before any work starts, you get a proposal in writing, with the one-time build and the monthly costs on separate lines. Our cost guide walks through what makes a parts store a bigger job, and you can send us your store link to begin.
