Okay, I need to create a professional wiki-style document about SMM (Social Media Marketing) under the categories of Technology > Web Development > Marketing Tools. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, detailed, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "SMM (Social Media Marketing)" as H1. Then an overview section explaining what SMM is, its importance in web development, maybe a brief history or current trends.

Next sections. Maybe break it down into key components like strategies, tools, analytics, challenges. Each of these can be H2 headings. Under each, more specific points with H3. For example, under "Key Strategies", have H3 for content marketing, influencer partnerships, etc.

Need to include examples of SMM tools. Maybe a table comparing different platforms like Facebook Ads Manager, Instagram Insights, Google Analytics. Also, mention some code snippets if relevant, but since it's about marketing tools, maybe not necessary unless discussing APIs or tracking codes.

Make sure to explain technical terms. For instance, when talking about KPIs (Key Performance Indicators), define them briefly. Use bullet points for lists of strategies or tools.

Check that the content is over 800 characters. Let me count: each section should be sufficiently detailed. Maybe add a "Best Practices" section with H2 and some H3 subsections like Content Strategy, Audience Engagement, etc.

Also include a references section at the end with links to official sources or related documents. Need to ensure all information is accurate. For example, when mentioning platforms, confirm their current features.

Avoid markdown in the thinking process but structure it properly in the final answer. Make sure each H2 and H3 are correctly formatted. Use bold for key terms if needed, but not overdo it.

Wait, the user mentioned "마크다운 형식의 문서" so I need to use proper markdown syntax. Let me outline:
