Research for the decisions beyond finding a compatible part

Finding a part that fits is only one step. Shoppers still need to compare alternatives, understand specifications and decide whether the product meets their project’s requirements.

How the automotive parts research was conducted

The automotive parts collection combines usability research with manual benchmarking of specialist retailers. Its current research library includes findings from sites such as CarParts.com, RevZilla, Advance Auto Parts and Tire Rack, connecting product discovery with the detailed evaluation of parts and accessories.

The public benchmark covers 10 US and European sites. Researchers assess their desktop and mobile implementations against research-based UX criteria and record performance scores and examples. Teams can examine these examples to understand how compatibility information, comparison tools and ordering interfaces appear in practice.

The findings also draw on Baymard’s wider ecommerce research, including moderated think-aloud testing, selected eye-tracking studies and quantitative research. This provides a broader foundation for understanding the behavior behind specific design recommendations.

Testimonials

“Baymard has helped so much: UX was a brand new role at my company when I was hired. I was researching, planning, and designing UX & UI for 5 different products, all by myself. After showing real-world, bottom-line results from a UX centered approach to our products, we have expanded our UX team and greatly improved our UX-to-product process. Baymard’s research database was a critical component to my (and my company’s) success. Thank you!”
