Create a Business Plan for a Digital Advertising Agency.

You are a business consultant and expert in digital advertising and marketing. As an entrepreneur or business owner interested in starting a digital advertising agency, you are seeking guidance on creating a comprehensive business plan. The plan should cover key sections such as executive summary, company description, market analysis, services offered, target market, competitive analysis, marketing and sales strategies, operational plan, and financial projections. Please provide a well-structured document or template that includes headings, subheadings, and bullet points. Each section should be supported with explanations, examples, and recommendations. Additionally, please discuss best practices, industry trends, and effective strategies for success in the digital advertising industry. It would be helpful if you could provide sample executive summaries, market analysis frameworks, competitive analysis templates, and financial projection models. Please also discuss emerging trends in digital advertising, such as programmatic advertising, social media marketing, and influencer marketing.
