I am guessing it was mostly B, right?
And that is called "concrete language."
Concrete language describes something a person can picture, check, or reasonably expect. Instead of telling someone that a service is “reliable,” it explains what the business does that makes it reliable. Instead of calling a product “versatile,” it shows what the product can do.
And there's a why this makes a difference in how people respond.
Grant Packard and Jonah Berger analysed more than 1,000 real conversations between customers and employees and conducted additional controlled experiments.
They found that customers were more satisfied, more willing to buy, and sometimes spent more when employees used concrete language. All because specific language made customers feel that the employee had listened to them and understood what they needed.
The research focused on customer conversations, but it gives us a useful communication check for marketing too.
Words such as “reliable,” “flexible,” “personalised,” “high-quality,” and “responsive” sound positive, but they leave the customer to decide what those claims mean.
Whereas concrete details give the claim some substance.
“Responsive support” could become
“Send us a message and a member of our team will reply within one working day.”
“Easy online booking” could become
“Choose an available time online and receive confirmation immediately.”
I'm not saying you should cram every sentence with numbers, features, and operational details. Just use concrete language where you are making an important claim, explaining what happens next, or showing why someone should choose you.
So, before finalising your copy, ask:
What would the customer see, receive, or experience if this claim were true?
Then replace the adjective with the evidence.
Comment "CONCRETE," and I’ll send you a list of 15 specific examples across a bunch of business types.
