Part number search is the entire game
Auto parts buyers arrive with a specific identifier — an OEM part number, or a vehicle year-make-model. A site that cannot resolve either into the right product loses the sale to one that can, regardless of price or stock.
This is the trade where per-product indexing pays off hardest, because the search terms are unusually specific and unusually numerous. Every part number is a query nobody else is competing for properly.
What gets built
Part-number and cross-reference search, vehicle compatibility lookup, mechanic and garage account pricing, WhatsApp enquiry with photo support for identifying an unknown part, and per-part indexed pages.
