Content pattern
Answer Capsule
Also: answer capsule, answer block, answer paragraph
The pattern helps human readers first. Every sentence names the entity (the business, the product, the city) instead of leaning on "it" or "this", so a reader who lands mid page still understands it.
There is no required length. Write the plainest complete answer, state the facts a buyer would check (price, location, who does the work), and keep marketing adjectives out.
