Copywriting is the craft of words that cause an action: read on, book a call, buy. Style without a job is literature. Marketing needs a job.
One reader, one action
Write to a person in a situation. Name the pain in their words. Promise one outcome. Ask for one click. Extra offers dilute the page.
Structure that holds
Headline with a stake. Proof you have done this. Objections answered in plain language. Call to action that repeats the promise. That outline beats cleverness.
Edit
Cut the first sentence. Cut adjectives you cannot show. Read it out loud. If you would not send it to a customer, it is not ready.
