Choose as many words that decsribe your listing. eBay search function is set or default to Best Match and most people do not change the default setting so by using as many words that describe your item the better. Do not copy another sellers title. eBay does allow that now but it does look bad.That s about it unless you pay more for feature and front page upgrades.
Offer Free Shipping on your listing and put a price of 99 cents so it lands on the first page during a search for that item.
