It seems there was an issue with generating the requested post. However, I can guide you through the process of creating it manually based on your WordPress SEO guidelines.

Here’s an overview of what to do:
1. Title
For the keyword “마샬연결범용”, you would combine relevant long-tail keywords related to the “Marshall connection” topic, reflecting both 2024 and 2025 trends. The title should avoid special characters and use a structured format like this:

2. Content Structure
H2 and H3: Use a structured format with headings like:
H2: “Marshall 연결 방법 확인하기”
H3: “Bluetooth 연결 설정하는 법”
H2: “Marshall 스피커 연결에 필요한 장치와 옵션 보기”
H3: “유선 연결 방법 상세 더보기”
3. Internal and External Links
For internal links, use non-anchor-text links like /yourpage?s=keyword, ensuring all internal links are set to target=”_self”.
For external links, use reliable sources with CTA buttons that are styled in a specific format (blue, orange, green buttons) and placed at the end of the first subheading.
4. CTA Example Code
