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.
