Which seller or listings does Ebay algorithm FAVOUR?

[greencrest-intl]

My question, if anyone kind enough to explain.

We,ve had a store for many years on ebay with a steady decline over the last 12-24 months  even after discounts and promoting...

Ebays sales for many specific components we sell, actually hasn't even dropped much overall over the last 24 month period.

PLUS, on ebay's "Product Research" for specific  items,

it shows 10% of sellers account for 90%! of sales for this item/category.

What is their secret to get 90% of the sales?

Is it the seller being favoured or is it the listing?

Is it because quantity of items they have listed in that range? (Which means 90% isn'tt the figure to judge by, as more lines will interpret higher percent)

Promoted listings..?

The question still baffles many, if sales on ebay research have not been effected on their graphs , who is getting the sales if so many sellers complaining of drop?

I think that a lot of it is simply that once you get traction, you stay higher in the search rankings.

So literally, the more you more you sell, the more viewable your listing is, which in turn means that your more likely to sell.  

I have a couple of listings on another account with hundreds of sales and they are both virtually always first in search without having to promote them.

Obviously price does come into it, but as long as your not way out, you will stay at the top.

The other side of it, is sheer volume of listings.  The bigger sellers obviously have more listings, which in turn means more visibility, which means more sales.....
