Why Xiaohongshu (RedNote) Became China’s Default Search Engine for Daily Life
It’s not about algorithms. It’s about answers you actually believe.
When I Search, I Ask AI. When My Wife Searches, She Trusts a Stranger in Suzhou.
When I want to figure something out online, I now mainly use AI-powered tools like Deepseek, Perplexity and ChatGPT. Someone still uses Google - except for verification? But my wife? She turns to Xiaohongshu.
Whether it’s finding a new brunch spot near the Bund
or—just the other day—looking for a tax attorney in Shanghai, her first step is scrolling through posts on Xiaohongshu. Not Dianping. Not Baidu. Not even WeChat. It’s Xiaohongshu.
Xiaohongshu, or RedNote, gained some visibility outside of China during the TikTok ban panic, when users were scrambling for alternatives. But that comparison always missed the point. At first glance, you might think Xiaohongshu is just an “Instagram for China.” That was never quite accurate—and it’s now completely outdated.
What began as a PDF shopping guide for Chinese tourists looking for what to buy overseas has quietly morphed into one of China’s most powerful search engines with 600 million daily searches and more than 330 million monthly active users. Yes, search engine. Not in the Baidu sense of crawling the open web, but something far more human and—depending on the type of query—arguably more useful: indexing lived experience.
The Female Tilt That Turned Into Strategic Gravity
To be fair, Xiaohongshu is predominantly female. That’s no secret—its community has long been strongest in fashion, beauty, wellness, and lifestyle. But this gender skew turned out to be a strategic strength. The platform became a decision engine for everyday life—not driven by algorithmic clickbait or ad auctions, but by people sharing what worked for them.
Need the best moisturizer for sensitive skin in a dry Beijing winter? There’s a note for that. (Don’t ask me why I know that. Just don’t ask - I live here now too long!)
Want to know how to prepare your kid’s overseas school application from within Shanghai? Someone has posted the entire process—forms, embassy visits, where they got stuck, what they’d do differently. No SEO-optimized listicle. Just real friction and real resolution.
That’s the product: friction already endured by someone else.
Xiaohongshu Doesn’t Return Webpages. It Returns Decisions.
Yes, it’s messy. There are amateurs posing as experts, affiliate links under layers of storytelling, and the occasional influencer scandal. But for high-context, taste-sensitive decisions—where nuance matters more than facts—Xiaohongshu outperforms traditional search engines by a wide margin. No wonder Tencent wants a bigger slice of the pie—despite already owning more than 13% of Xiaohongshu.
Xiaohongshu doesn’t return webpages. It returns answers—delivered in real-world context, wrapped in receipts, photos, regrets, and maps. This is not a Baidu-style information index. It’s a peer-reviewed lifestyle encyclopedia.
And in a landscape where trust is becoming scarcer than attention, Xiaohongshu’s messy transparency ends up feeling more honest than Baidu’s structured neutrality.
From Content to Checkout: Xiaohongshu’s Closed Loop
That’s also what makes it so effective as a commercial platform. This isn’t just a social media feed with high engagement. It’s a conversion system built on trust. People don’t browse into purchases—they’re gently pulled there by someone relatable telling them a story that feels personal.
The 种草–拔草 “seed and harvest” model—common marketing jargon in China—isn’t a metaphor here. It’s the literal UX architecture. Users get “seeded” with desire, then “harvest” that impulse through native commerce, sometimes within the same post. No need to retarget users who never left.
From an investor standpoint, the monetization logic is the most interesting part. Xiaohongshu reportedly derives about 70% of its revenue from advertising. But this is not the Baidu model of keyword auction spam. This is high-intent, trust-based traffic that converts. The platform doesn’t sell eyeballs; it sells intent filtered through credibility.
And it does so with fewer steps, fewer wasted impressions, and almost zero friction between recommendation and transaction.
The Algorithm That Forgets Nothing (and Everyone Wins)
The long-tail mechanics are also powerful. Xiaohongshu’s algorithm can resurface content from six months—or even two years—ago, if the user query aligns.
That reduces the cost of content production, increases the lifetime value of each post, and flips the entire “content shelf-life” equation on its head. This is not the 24-hour decay cycle you see on TikTok or Douyin. Xiaohongshu’s posts are more like buried truffles. All you need is the right prompt to dig them back up.
And because older posts stay useful, users trust the platform more. Brands get recurring value. And the platform itself builds a flywheel of increasingly compounding content density.
Diandian vs. Baidu: The Battle for Human-Centered Search
In 2024, Xiaohongshu launched an AI-powered search tool called 点点 (Diandian), further pushing into Baidu’s core territory. But instead of returning ten blue links, Diandian surfaces content created by people who’ve actually done the thing you’re trying to do, or bought the thing you’re thinking about buying.
Want a CPA for cross-border filings? Here’s someone in Suzhou who’s already been through it. Want a quiet café with good Wi-Fi? Here are three options, complete with crowd-sourced photos and comments on both the Wi-Fi signal and the latte quality.
So while my wife is hunting down a trustworthy accountant via a woman in Suzhou who once posted about VAT and Cayman structures, I’m left thinking about something else entirely. Xiaohongshu didn’t just make a prettier Instagram. It quietly re-wired how people in China search—and more importantly, how they decide.
Meanwhile, Baidu launched a minimalist search app called 心响 to try to win back users with a “clean search” pitch. In theory, that sounds appealing. In practice, users didn’t want less noise—they wanted answers that matched their context.
And the market is noticing. Baidu’s core advertising revenue fell 6% year-over-year in Q1 2025—a reflection of where search intent is migrating. I wrote about this in more detail in my last article, but the core issue is simple: Baidu indexes static web pages. Xiaohongshu indexes outcomes.
It’s Not Perfect. Especially Not for Medical Advice or Power Supplies.
It’s not for everything. You probably don’t want to rely on it for medical advice.
And yes, sometimes a post reads like someone typing through a breakdown at 2 a.m. about why their new vitamin C serum ruined their week. But the key difference is: you still want to read it - ok not really me but my wife!
Because for all the fuzzy, personal, real-world decisions—where you don’t need absolute truth, just a sense of what worked for someone like you—Xiaohongshu is quickly becoming the default interface.
And that, to me, is the big lesson: in China’s modern internet, the platforms that win aren’t the ones that inform. They’re the ones that convince.
Even if the conviction comes from a woman in Suzhou who has no idea she just changed how my wife’s company files taxes.
Call Me a Passive User. Or Just a Husband with Wi-Fi.
So yes, I admit it: my wife will be very proud that I finally wrote about her favorite app. The same app I once dismissed as “lipstick Pinterest with better lighting.” The same app I sometimes dare to question—only to be proven wrong when my wife digs up this new brunch place with a great view of Lujiazui.
And no, I’m still not a user. I don’t post. I don’t comment. I don’t save skincare routines - who would have thought!
But after living in China long enough, I know far more about Xiaohongshu than I ever meant to. Friends forward posts. Conversations drift. Someone pulls out a screenshot mid-dinner. I now know how to spot fake discount codes from three screens away, and I can recite half the sunscreen tier list by memory. That knowledge lives rent-free in my brain. Xiaohongshu—or more precisely, the people around me—put it there.
I guess I’m what you’d call a reluctant, ambient user.
The algorithm doesn’t need me. Everyone else already trained it for me.
I stop writing now. I have a dinner date with my wife. Guess where she found the new restaurant?

I think RedNote is a great case study on why user behaviors and culture matter a lot. It's not like Instagram, Pinterest, or any other social media platform is doing anything different from what RedNote is doing from a technical/platform perspective. Likes, comments, follows, posts, an addictive algorithm. Intentionally or not, RedNote has cultivated it's user base to provide timely information on almost anything and everything now. And, as a great point, the search accuracy/relevance is underrated but critical. Spot on observations in this article.
