"Studies have proved that celebrities endorsing a company or brand can greatly increase consumers' awareness of an advertisement, capture their attention and make the advert more memorable. Think of Jack Dee and John Smith’s Bitter, Linda Barker and DFS or George Foreman and his range of ‘Lean, Mean Grilling Machines’.

Additionally, when a celebrity endorses your company, it tells the consumer that the company is reputable, has good products or good customer service and is a sound company to deal with. Remember, the celebrity’s own image and reputation are at stake."
