eBay Promotion Statistics...

[simms]

A while back on eBay when promoting your auctions it would tell you to

Add Bold! Bolding separates your auction from others and increases bids on your item by 33%*.

Since then, eBay doesn't show the stats anymore. Is there a way I can find out what are good upgrades for eBay auctions?

It is Women's clothing, but I have Gallery and Bold on it already.
