Probably include primary keyword. Something like "安全な動画視聴の完全ガイド：著作権とテクニカル・メンテナンスを理解した安心な視聴環境の構築法". But must include primary keyword exactly? The instruction says "Primary Keyword: "安全な動画視聴"". So include that phrase. Could be part of title.

We need 5-7 Heading 2 (##) sections. Each with subheadings (###). Include bullet points, paragraphs, and at least one table.

We also need to incorporate secondary keywords.

We also need to ensure it's at least 1000 words. We'll write a lengthy article.

We need to write in Japanese, polite.

We'll produce sections:

1. 安全な動画視聴の重要性
2. 合法サイトと違法サイトの見分け方
3. テクニカル・メンテナンスの基本
4. 著作権と安全な視聴環境！違法サイトを使わない理由と重要性
5. 安全な動画サービスの比較表
6. 女性ユーザーの視点からみる安全基準
7. 今後のトレンドと対策

But need exactly 5-7 heading 2. Could combine.

We'll produce maybe 6 sections.

Each section with subheadings.

Include bullet points.

Include a table comparing services.

We also need to include secondary keywords naturally.

We also need to include "著作権と安全な視聴環境！違法サイトを使わない理由と重要性" phrase exactly? The secondary keyword is that phrase. It should appear somewhere in the article. Possibly as a heading or within text. It includes exclamation mark. Might need to include exactly that phrase. The instruction: "Secondary Keywords (Distribute naturally across sections): テクニカル・メンテナンス, 著作権と安全な視聴環境！違法サイトを使わない理由と重要性". So we need to include these two phrases somewhere. They can appear anywhere, but probably each phrase at least once.

Thus include "テクニカル・メンテナンス" and "著作権と安全な視聴環境！違法サイトを使わない理由と重要性" somewhere.

We'll incorporate them.

Now write.

We need to output exactly:
