I once stumbled upon the titular statement while browsing a design firm's website, which shall remain nameless. This oxymoronic statement says nothing. Specializing is, by definition, the act of becoming an expert in a particular subject of skill. "Specializing in a wide array of work" is therefore, not specializing at all, but actually the exact opposite.
My aim isn't to pick on a particular business, but rather use it as an example of what misguided language can do to an otherwise excellent design firm and how it undermines one's credibility as well as ability to deliver maximum value.
Designers too often come up with self-describing statements that sound elegant and distinguished, but most of the time, are buzzword-laden descriptions (dare I say deceptions?) of their firms that ultimately are devoid of all meaning, as their verbiage is so tortured and convoluted that it ends up meaning nothing.
When it comes to client-facing descriptive statements, it's best to keep it simple, or better yet, leave it to professional copywriters and communicators* who understand the language well enough to translate your beautiful, wild, crazy and creative ideas into human-intelligible language, which in turn will keep your would-be clients longer on your website, increasing your chances of making a sale.
One thing that is often overlooked about good copy, and specifically of the kind that helps you sell your services, is that effective copy can sound dull or worse - crime of all crime - salesy. But ultimately, the only thing that matters is effectiveness. If said copy helps you sell your services or accomplish any other goals, then it can be considered effective copy. Otherwise, it’s just a vanity project.
