The algorithm is always made to be "opaque" so as not to give anyone a way to steer it in one's own favor.
The supposed "level playing field" (which never is level). Paid promotions is one way to easily tilt that field.
However, Amazon vendors (in all likelihood) do get site/search analytics to glean data from. Search queries
are a great indicator of a perceived need. RustyTheeth is correct in suggesting you do a search for Vanderhall
parts there to spur more vendors to supply parts and perhaps more competition too.

Yes thank you Nicoli! I type in VANDERHALL every day. in hopes we can get a 600$ piece of glass for 20$ Crack n dent.
Thx
