Okay, I need to create a Wikipedia-style document about "Personalized Marketing" under the categories of Economics, Market and Business, and Marketing Strategy. Let me start by understanding the requirements.

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

Starting with the title: "개인화 마케팅" as given. Then an overview section explaining what it is, its importance, maybe a brief history or current trends. Next sections could be on key components, strategies, challenges, case studies, and future trends. Each of these can have H2 headings, and sub-sections with H3.

For the content quality, I need to ensure that all information is accurate. For example, explaining what personalized marketing is, how it differs from traditional methods. Mentioning technologies like data analytics, AI, CRM systems. Maybe include examples of companies using it effectively, like Amazon or Netflix. Also, discuss challenges such as data privacy issues (GDPR), the need for customer trust, and technical complexities.

I should use terms like "data-driven," "customer segmentation," "behavioral targeting," but explain them briefly. Maybe a section on strategies: how to implement personalized marketing, tools used, best practices. Then challenges and solutions. Case studies would be good examples, maybe a table comparing different companies' approaches.

Need to check for markdown formatting: H1 with #, H2 with ##, H3 with ###. Use bullet points or numbered lists where appropriate. Maybe include a code block if there's an example of a script used in personalization, but not sure if that's necessary here. References could be links to studies or articles.

Wait, the user mentioned "필요시 참고 자료나 관련 문서 섹션" so maybe add a references section at the end with sources like academic papers, industry reports, or case studies.

Also, ensure the document is over 800 characters. Let me check: each section should be detailed enough. The overview might need to be a paragraph or two. Each H2 section can have several paragraphs and sub-sections.

Now, I need to flesh out each section with detailed information. Make sure to explain terms like CRM (Customer Relationship Management), AI algorithms, etc., in simple terms. Use examples where possible. Check for accuracy: for instance, mention GDPR compliance as a challenge. Also, include how companies like Amazon use customer data to recommend products.

Avoid being too technical but still professional. Maybe add a table comparing traditional vs. personalized marketing approaches. Or a list of tools used in personalization (e.g., CRM software, analytics platforms).

Need to ensure that the document flows logically and covers all aspects required. Check for markdown syntax: headings, lists, tables if any. Make sure it's over 800 characters. Let me start writing each section with these points in mind.
