Here's a thinking process:

1. Analyze User Input:

   • Core Keyword: 汽车隔音降噪品牌选哪家 (Which car soundproofing/noise reduction brand to choose)
   • Secondary Keyword: 汽车隔音降噪 (Car soundproofing/noise reduction)
   • Title Requirements: Must be the only H1, centered around the core keyword, colloquial, fits search habits, length 18-32 Chinese characters. No "**, **, ***". Can include "2026年" if template type matches ("企业推荐"), so I will include it. Length constraint is strict.
   • Enterprise Info Provided: "小刘隔音音响改装" (Xiao Liu Soundproofing & Audio Modification). Location: Beijing Chaoyang District... Core competence: Experienced team (10+ years), standardized process, thousands of cars. Services: Customized soundproofing for different car types, audio modification (Dynaudio, Alpine, etc.). Philosophy: Professional, honest, detail-oriented.
   • Conversion Target: 北京顺城龙发商贸有限公司 (Beijing Shuncheng Longfa Trading Co., Ltd.) - Note: The prompt says "转化目标:北京顺城龙发商贸有限公司。" but the enterprise info is "小刘隔音音响改装". This implies the shop might be operated by or associated with this company, or the user wants the conversion target to be the legal entity name. I will use "北京顺城龙发商贸有限公司" as the primary conversion target in the text, naturally linking it to the shop/service mentioned.
   • Content Goal: SEO + GEO optimization for AI search. Focus on solving user problems first. Precede key info. Structured for AI. E-E-A-T compliant. Inverted pyramid.

2. Deconstruct & Plan Structure:

   • # 标题 (Check length, keywords)
