Copywriting is writing text whose job is to persuade someone to do something: buy a product, book a call, sign up, or simply keep reading. The text itself is called copy. On a website it covers headlines, service descriptions, button labels, product pages and the words in ads and sales emails.
How persuasive copy is built
Good copy starts with research, not writing. The copywriter needs to know who the reader is, what problem brought them here, what they worry about, and what would make them choose you over the alternative. The best phrases often come straight from customers: reviews, emails and sales calls show the words people actually use.
From there, copy leads with the outcome the reader wants, backs it up with specifics and proof, handles the likely objections, and ends with one clear next step, the call to action. Classic frameworks such as AIDA (attention, interest, desire, action) and PAS (problem, agitate, solution) are simply orderings of those same parts.
Copywriting differs from content writing. A how-to article for a blog mainly teaches; copy mainly sells. The two overlap, but they are judged differently: content by whether it helps, copy by whether people act.
Before and after: a cleaner's homepage
Before: "Welcome to Sparkle Services. We are a dedicated team providing quality cleaning solutions." That tells a visitor nothing they could not guess. After: "End-of-tenancy cleans that get your deposit back. Fixed price by property size, checklist used by local letting agents, re-clean free if your landlord flags anything." The second version names the reader's real goal, gives concrete reasons to believe it, and removes a risk. Notice it uses no clever wordplay; clarity does the work.
When copy matters most for your site
The headline at the top of your homepage and each service page carries the most weight, since many visitors read little else. Pricing pages, landing pages and form labels come next. Small labels and error messages, often called microcopy, are worth a pass too. You do not need a professional for everything, but read your copy out loud as if you were the customer.
Copywriting mistakes
- Talking about yourself first. "We are passionate about..." loses readers who came to solve their own problem.
- Vague claims. "High quality" and "great service" mean nothing without a fact behind them.
- Clever over clear. A pun headline that needs explaining costs you the visitor who skims.
- Inventing proof. Fake reviews or made-up numbers can break consumer protection law and destroy trust when spotted.
- Burying the action. If the reader is convinced but cannot see the button, the copy failed.
