Some domain buyers on ebay favor the search function, for example LLL buyers. If selling names belonging to a distinct category such as LLL, it makes sense to include both the domain name and keyword(s) indicating "3 letter" in the title. Otherwise, put the full domain name with extension in the title, nothing else.
White space increases readership.
Good names sell themselves. Opportunistic buyers tend to look at all domain title listings as fast as possible and click on those of interest. The only data these buyers look for in the title listings is the domain name and price. All other title text such as "RARE PERMIUM IPOD DOMIAN" is ignored. Buyers also learn to avoid clicking on deceptive titles by recognizing clues, for example one seller has established a pattern of offering a strong keyword.com in the title while offering k-e-y-w-o-r-d.com in the listing. Listing design is less important than content: domain name, registrar, creation date, expiration date, payment terms, keywords for search. Keep the listing design simple, buyers appreciate it, no one has time to waste. If you sold a crappy name for $100 and a less crappy one for $50, overall you're doing OK.
