How Servo Motors Work

I’ve noticed that distributors (Jameco, Mouser, etc) have a surprising number of introductory education articles. I’ve seen this pattern on websites for car dealerships and HVAC installers, so I assumed it was for SEO purposes. But electronic parts distribution seems like a much more niche audience; why bother with SEO?

Some may be application notes from the manufacturers.

Jameco also supplies mid level engineering firms, so similar to application notes. Think automation integration company buying xyz specialty robotics controller.

I think of mouser as more like digikey, so I don't really know why they would have similar educational information above the level of PCB board component. But, they may also have business in the low-quantity higher margin business.

Tldr: not seo. Customers actually need to know about the product
