Marketing a new brand of creative content writing agency requires a well-thought-out strategy to attract students and build trust. Here are some steps to help you get started:

1. Define Your Unique Selling Proposition (USP): Identify what sets your creative writing service apart from the competition. Whether it's affordable prices, fast turnaround, exceptional quality, or specialized expertise, your USP will be the foundation of your marketing efforts.

2. Target Audience Research: Understand your potential customers. Know their demographics, needs, and pain points. Are you targeting businesses, agencies, or professionals? Knowing your audience will help you tailor your marketing efforts accordingly.

3. Create a Professional Website: Your website is your online storefront. Make sure it's user-friendly, visually appealing, and mobile-responsive. Include clear information about your services, pricing, guarantees, and contact details. 

4. Content Marketing: Produce high-quality, informative content related to creative writing. This could include blog posts, guides, and tips on academic writing. Share this content on your website and through social media channels.

5. Search Engine Optimization (SEO): Optimize your website for search engines to increase its visibility in search results. This involves using relevant keywords, meta tags, and building high-quality backlinks.

6. Social Media Presence: Create profiles on popular social media platforms, like Facebook, Twitter, and LinkedIn. Share informative and engaging content, engage with your audience, and run targeted ads to reach potential customers.

Remember that building a reputable creative writing service takes time. Focus on delivering quality and building trust, as word-of-mouth recommendations can be one of your most powerful marketing tools in the long run.
