Speech - Clearly enunciate all words.

Believable - You must sound like you actually are a true user and believer in the product being sold and you do this by the tone of your voice.

Natural - It is very important, when describing or selling a product, that you appear very natural and move as though it were an everyday event to stand up, talk about, and describe the product being sold.

Flexibility - In order for a model to have a long career in commercials, you must be able to play more than one role. For instance, a model who does a commercial for toilet bowl cleaners, doesn't want to be known and thereby stereotyped with only that particular item. Producers as well as client companies tend to stereotype people just as easily as viewers do. Avoid doing a lot of one type of commercial.

Eye Contact - Always look and speak directly into the camera unless specifically instructed to do otherwise.
