I've lost count of how many websites for public relations agencies, or writers, or designers, or marketing consultancies that I have visited claiming to be specialized in dozens of things.  You will see the navigation bar across the top and a tab entitled "Specialties." You will then click on that and find several items, like a marketing agency that claims to specialize in SEO, native advertising, design, and social media, to name a few. Or a writer who specializes in medical writing , technical writing, long format, blogs, and many other forms of writing.

<strong>It's a specialty, singular.</strong>

Here's the thing: you can't be specialized in so many fields. You may have <em>experience</em> and <em>knowledge</em> in those fields, but the word specialty, by definition, is limited to one field.

Merriam-Webster provides this definition:
<blockquote>something that a person or place is known for making or producing very well
<p class="bottom_entry">an area of study or business that a person specializes in or has special knowledge of</p>
</blockquote>
<p class="bottom_entry">Notice that it doesn't say "things" or "areas of study." There is no plural in specialty.</p>
<p class="bottom_entry">Maybe you are focused on different things.</p>
<p class="bottom_entry">The truth is most marketing/advertising/public relations agencies specialize in their respective disciplines and <em>focus</em> on different aspects. That is, a public relations firm specializes in public relations but focuses on media relations, strategic planning and reputation management, for example.  And then there are agencies that specialize in media relations or strategic planning or reputation management, but they claim to specialize in all three I am a bit suspicious.</p>
