Auto parts (OE) newbie struggling with ads and listings — need real advice

I work as an Amazon assistant and started my own side hustle selling OE auto parts. I know the products and have basic experience, but I’m completely stuck.

Here’s what I’m doing now:

Two ad campaigns: broad match for year/model + part, and ASIN targeting against competitors with higher prices or worse images
I just guess on bids and adjust randomly based on where I show up
Listing copied from competitors, basic images, partial A+
No reviews or QA — I don’t do any fake stuff

My problem: competitors with similar products, similar prices, and slightly better ratings are crushing me. I don’t get why.

A few honest questions:

How do you actually structure ads for OE parts with fitment?
How do I build a real keyword list when parts fit so many years/models?
What actually moves the needle for conversions and organic rank?

Would really appreciate real advice from people who actually sell auto parts.

If your parts fit multiple vehicles, create separate variations for each major model/year. Then run campaigns targeting those specific fitment keywords.
Use keyword tools (ABA, Helium 10) to verify which models have actual search volume
Invest in professional images — for auto parts, clarity and detail matter. Show the part from multiple angles.

The fitment variations part is something I ignored at first and it definitely made the listings messy. Splitting by model/year seems like the safer move, especially if the keyword tools show real volume instead of just guessing. The image advice is solid too — for auto parts, blurry photos basically kill trust.

Competitors outselling you with similar price/ratings? Check their organic keyword rank. They might rank higher for high-volume terms even if your listing looks similar. Use a keyword tracker. Then run exact match campaigns on those specific terms with Top of Search placement.

One trick for OE parts: use negative keywords aggressively. For a part that fits Ford 2015-2020, negative “Chevy”, “Toyota”, and any year outside your range. This keeps your budget focused.

Auto parts buyers are often male and review-conscious. Without reviews, you’re fighting uphill. Use Vine (free tier) to get first 2 reviews. Then use the “Request a Review” button on every order. Don’t use any off-platform review services.

Your random bid adjustment is killing you. Seriously.
Set a baseline using suggested bid, then add placement modifiers (like +30-50% for Top of Search). And don't change bids every day — give each campaign 7-14 days of consistent data before you touch anything.
I used to do the same thing. Stopped, and my ACOS dropped 15%. Patience pays.
