The person who shapes and sculpts the words in an advertisement or website is known as a copywriter (but we like calling them wordsmiths because that sounds way cooler).
Every word in your advertisement or website should convey a tailor-made message to your target audience. Whether your ultimate goal is to inform or persuade, you're at the right place.
Hire a copywriter, it's the 'write' thing to do.
The service of Webbado is excellent! You can have a look at our awesome SAVLU website.
