Okay, I need to create a Wikipedia-style document about "Customer Lifetime Value" under the categories of Economics, Market and Business, and Service Marketing. Let me start by understanding what CLV is. It's a metric that estimates the total revenue a business can expect from a single customer account throughout the business relationship.

First, the structure: H1 for the title, then an overview section. I should explain what CLV is, its importance in service marketing. Then break down into sections like definition, calculation methods, significance, strategies to improve it, and maybe case studies or examples.

Wait, the user mentioned using H2 and H3. So after the introduction, maybe H2 for "Definition and Concept", then H3 for subpoints like "What is CLV?" and "Key Components". Then another H2 for "Calculation Methods" with H3s on formulas and factors affecting it.

I need to make sure the content is accurate. For example, CLV can be calculated using average purchase value multiplied by frequency and lifespan. Also mention different approaches like historical vs predictive. Maybe include a formula in a code block or as a mathematical expression.

Significance section should talk about how businesses use CLV for resource allocation, customer retention strategies, etc. Strategies could involve improving customer experience, loyalty programs, personalized marketing.

I need to check if there are any common mistakes in explaining CLV. For example, differentiating it from Customer Value vs. Customer Lifetime Value. Also, mention that it's a forward-looking metric, not just past data.

Include examples or case studies? Maybe a simple example with numbers. Like calculating CLV for a subscription service. But since the user didn't specify, maybe keep it general unless needed.

References: Maybe cite some marketing textbooks or reputable sources like Harvard Business Review. But since this is a wiki-style document, perhaps just mention key authors or theories without specific citations.

Avoid jargon where possible, but if I use terms like "churn rate" or "discount rate", explain them briefly. For instance, churn rate is the percentage of customers who stop using the service in a given period.

Check for clarity and flow. Make sure each section builds on the previous one. Use bullet points or lists for key components or strategies to make it readable.

Also, ensure that the document meets the 800-character minimum. Let me count: the introduction is about 150 words, then each section adds more. Should be okay.

Wait, the user said "최소 800자 이상" which is 800 characters, but in Korean, that's around 400-500 words. But maybe they meant 800 words? The original instruction might have a typo. However, I'll proceed with the given requirement of at least 800 characters, which is manageable.

Now, structure:

Make sure to use H2 and H3 properly. Avoid markdown in the thinking process but structure it correctly in the final answer.
