Depends on what your selling and how much of it you sell.
If your sales are higher against similar/same products from other sellers then you will be place higher. Thats generally how it works I don't think PS level comes in to it, thats just a measure of your gross monthly sales.

Thanks for that, I sell phone cases so very competive I know, I understand that you have higher power seller status if you have more monthly sales , spoke to eBay and they say if a silver member has same product etc and same level of sales as a gold/plat seller they will be higher just because of there higher status .
