If a company wants to advertise its goods in the Internet - they pay to Google for ads, links.
Some companies (may be) would agree to prepare concise technical info about items they sell (kind of excell tables) and publish it on kagi.com for free.
Some internet users (may be) ready to pay for filtered and structured info about items they want to buy.
