Number one: ALWAYS always fill out the item-description line to the max.  Any descriptive words or key words to lead buyers to your auction helps you sell!
If you have toddler shoes, don't just type in "Yellow Toddler Shoes"
It is important to fill out the line with "Baby, kid, child, size___ Infant, Play, etc"
There are many times I have come across auctions that have not maximized their benefit in this way and I send them a note telling them how much it could help them!
I, myself, still have a lot to learn about ebay, and I probably will never fully dig into every detail, but maybe we can all work together to figure this thing out!
