A good auto parts title follows one pattern: brand, part type, part number, fitment summary, condition. For example, “[Brand] Front Left Brake Caliper 18-B5012 for 2014-2018 Chevrolet Silverado 1500, Remanufactured.” A buyer can tell from that line alone whether the part might be theirs, and someone who searches the part number or the vehicle finds it.
The rest is trimming the same pattern to each channel’s limit and leaving out the things that make titles worse: repeated keywords, all caps, store promotions and fitment claims you can’t prove. For the bigger picture of selling parts online, see our page for auto parts sellers.
The pattern, piece by piece
1. Brand
The brand is whoever made the part. For an aftermarket part, that’s the aftermarket maker, not the vehicle maker. The vehicle goes in the fitment piece, after “for” or “fits”. For a used original-equipment part pulled from a vehicle, the vehicle maker is usually the brand. If you don’t know the brand, leave it out rather than guess.
2. Part type
Use the words a buyer types, not your supplier’s catalog code. “Alternator”, “Headlight Assembly”, “Power Steering Pump”. For parts that come in sides or positions, the position belongs here: front or rear, left or right (or driver and passenger side, if that’s how your buyers search). A buyer who needs a left caliper skips a title that doesn’t say which side.
3. Part number
Use the maker’s part number exactly as printed, dashes included. Buyers type it many ways, so your site search should match “18-B5012”, “18B5012” and “18 B5012” as the same thing. Our guide to organizing a large parts catalog covers search that forgives dashes and spaces. Interchange and cross-reference numbers usually go on the page, not in the title, unless there’s room and you’ve confirmed them.
4. Fitment summary
Give the main range: years, make, model, and engine if it matters. “for 2012-2016 Honda CR-V 2.4L.” If the part fits a long list of vehicles, summarize the most-searched range in the title and put the full list on the product page. Fitment should come from real data, such as an eBay compatibility list or a supplier’s file. Our guide to eBay Motors compatibility on your own website explains where that data lives. If a part has no fitment data, leave fitment out of the title and lead with the part number.
5. Condition
End with the condition, using the same words as your condition field: New, Used or Remanufactured. Only add words like “Tested” when the part really was tested, and say on the page what the test was.
Fit the pattern inside each channel’s limits
The pattern stays the same. What changes is how much room you get.
| Where the title appears | Limit | What the official guidance says |
|---|---|---|
| eBay listing | 80 characters | eBay’s Trading API guide sets the maximum at 80, and its listing best practices say to use all 80 on relevant keywords. |
| Google Merchant Center | 1 to 150 characters | Google’s title attribute page says to put the most important details first, because users usually see only the first 70 characters or fewer. |
| Your own product page | No fixed limit | Google’s title link guidance asks for descriptive, concise titles and warns against keyword stuffing and boilerplate. |
When a title runs long, cut in this order:
- Filler words (“for your”, “great”, “high quality”).
- Long model names, where a shorter one is still clear (“2014-18 Silverado 1500” instead of “2014-2018 Chevrolet Silverado 1500”).
- Condition spelled out (“Reman” instead of “Remanufactured”).
Never cut the part number or the part type. Those are what people search.
Examples
The brands, part numbers and fitment below are made up to show the pattern. They aren’t real listings and they aren’t claims about any real part. “[Brand]” stands in for the maker’s name, so a real title will be a few characters longer or shorter.
Full version, for your own site and Merchant Center (96 characters):
[Brand] Front Left Brake Caliper 18-B5012 for 2014-2018 Chevrolet Silverado 1500, Remanufactured
Trimmed for eBay (75 characters):
[Brand] Front Left Brake Caliper 18-B5012 for 2014-18 Silverado 1500, Reman
A used alternator (63 characters):
[Brand] Alternator AL-40112 for 2012-2016 Honda CR-V 2.4L, Used
A part with a side (75 characters):
[Brand] Left Headlight Assembly 92101-XX000 for 2017-2019 Ford Escape, Used
A part with no fitment data (41 characters):
[Brand] Power Steering Pump 7G-2210, Used
The last one is short on purpose. Without real fitment data, the honest title gives the buyer the part number to match against their old part, and the page asks them to check it.
What not to do
Here are two titles that break most of the rules:
WOW!! ALTERNATOR GOOD USED FITS ALL HONDA L@@K
Alternator Honda Alternator CRV Alternator Civic Accord Alternator Generator
What’s wrong with them:
- Keyword stuffing. Repeating “alternator” four times adds nothing for the buyer. Google’s title link guidance gives the same word repeated in different forms as its example of what not to do. eBay’s search manipulation policy bans adding popular keywords that have nothing to do with the item, and it also covers how to word the name of a product your part works with. Read the version for your eBay site.
- All caps. Google’s Merchant Center guidance says to use capitals only where they belong, such as abbreviations. Part numbers and “2.4L” are fine. “GOOD USED” is shouting.
- “Fits all”. A buyer can’t check it, and a part that doesn’t fit comes back. List what it fits, or for a part that really is universal, give the size, thread or connector that decides fit.
- Promotions in the title. Merchant Center asks you to leave out prices, sale dates, shipping, delivery dates and the name of your store. Put free shipping and sale prices in their own fields, where they stay accurate.
- Symbols and junk. “L@@K”, emoji and stacked punctuation take characters and tell the buyer nothing.
- Internal codes. Your stock number and shelf location help your staff, not a buyer. Put them on the page or in your admin.
- Claims you can’t back up. “OEM quality”, “like new” and “tested” each need to be true for that exact part.
How titles feed search on your own site and Google
On your own store, the product title does more work than it does on eBay.
- Site search. Store search almost always reads the title, so a consistent pattern means “caliper 18-B5012” finds the caliper every time.
- Category pages. Titles show on product cards, often cut short on phones. Brand, part type and part number up front means the useful part survives.
- The page title and heading. Most store platforms build the browser title and the page’s main heading from the product title. Google’s title link page says it may build the title it shows in results from either one, so keep both clean.
- Google free listings. If you send products to Google’s Shopping results, the feed’s title field usually comes from the same product title. Our guide to Google free listings for used parts covers the rest of that feed.
The simplest way to keep thousands of titles consistent is to stop typing them. Store brand, part type, part number, fitment and condition as separate fields, and build the title from those fields with one template. Fix a field and the title fixes itself on the product page, in search and in the feed.
Titles that hold up across a whole catalog
A title pattern is only as good as the data behind it: a confirmed brand, the right part number, fitment from a real source and an honest condition. Get those fields in order and the titles almost write themselves, for eBay, for Google and for your own store. If you’re planning a store where titles, part-number search and fitment all come from one set of data, our auto parts sellers page shows how we approach it, and you can send us a sample of your current listings through the contact page.
