+## Cookie Warmup — CRITICAL for Authenticated Platforms
+
+Many platforms will return empty results or redirect to login if you navigate **directly** to a search URL without first visiting the home page. Always warm up the session in two steps:
+
+| Platform | Step 1 (warmup) | Step 2 (search) |
+|----------|-----------------|-----------------|
+| 知乎 | Navigate `https://www.zhihu.com` | Navigate to search URL |
+| Reddit | Navigate `https://www.reddit.com` | Navigate to search URL |
+| 微博 | Navigate `https://weibo.com` | Navigate to search URL |
+| YouTube | Navigate `https://www.youtube.com` | Navigate to search URL |
+| 雪球 | Navigate `https://xueqiu.com` | Navigate to search URL |
+| 路透社 | Navigate `https://www.reuters.com` | Navigate to search URL |
+| Bilibili | Navigate `https://www.bilibili.com` | Navigate to search URL |
+| 小红书 | Navigate `https://www.xiaohongshu.com` | Navigate to search URL |
+
+**Platforms that do NOT need warmup** (public APIs / no auth required):
+- Bing, Baidu, Quark, GitHub, arXiv, Wikipedia, BBC, HackerNews, V2EX
