As a result, marketing communications for most services drag around a heavier burden than communications for products. A bright red Porsche 911 convertible, for example, chants loudly and beautifully for itself. Very few services shout for themselves at all.

We implicitly trust most products. We trust that our new tyres won’t explode, our brown sugar will taste sweet, and our aspirin will relieve our headaches without bad side effects. But we are far less trusting and certain about most services.

We fret that our solicitors and auto mechanics will do more than necessary, and charge more than is warranted. We are concerned that the latest weight loss service will fail, just like the two before it. We worry that our remodelers will exceed their budget and finish weeks after they promise. We worry that the collection agency we hire for our service will badger our clients worth keeping and collect only a small part of our outstanding receivables.

So unlike communicating about products, talking about services must make the service more tangible and real, and must soothe the worried prospect. It’s not like selling Porsche automobiles.
