Baidu Tieba (百度贴吧) is China’s oldest and largest forum platform. Baidu launched it in 2003 as a place where any search term could spawn its own message board, called a “bar” (吧). Type almost any brand, celebrity, product, city or hobby into Baidu search today, and a Tieba bar for it probably already exists, built by fans, not by the brand.
That last point matters. Most Tieba bars for foreign brands were created by Chinese consumers, not marketing teams. A brand entering China often discovers its own name already has an active community discussing it, complete with unofficial rules, loyal moderators and years of posts the company never wrote.
How the bar structure actually works
A Tieba bar is a self-contained forum thread board around one keyword. Users post threads, reply, upload images, and rank posts by recency or popularity. Each bar has moderators (吧主) elected or appointed from within the community, and these moderators control pinned posts, banned members and the bar’s overall tone.
Bars sit in loose hierarchies. A big topic, say a car brand, might have one main bar and several smaller offshoot bars for specific models, regional owner groups or fan subcultures. Members build reputation through post counts and “levels”, a system closer to old-school Western forums like phpBB boards than to a modern social feed.
This structure rewards patience. Threads can stay active for years. A well-written post from 2019 can still surface in search results and pull in readers in 2026, provided the bar itself stays alive.
Why an older platform still matters
Tieba’s importance today has almost nothing to do with reach. It has to do with search.
Baidu owns Tieba, and Baidu’s algorithm consistently ranks its own properties, including Tieba threads, Baike entries and Baijiahao articles, high in organic search results. A brand name that has active, well-moderated Tieba discussion tends to show up on page one of Baidu search for that name, sometimes above the brand’s own website. For a foreign company trying to build trust with Chinese buyers who search before they purchase, that visibility is hard to replicate through paid ads alone. Our Baidu SEO and SEM services treat Tieba as one input into a wider search visibility plan, not a standalone tactic.
Tieba also keeps a genuine niche-community and fan-culture use case that newer apps struggle to copy. Xiaohongshu and Douyin favour short bursts of content from creators. Tieba favours long threads, archives and a sense of belonging to a specific group, whether that group is car enthusiasts, gaming fans, or owners of a particular skincare line. Recent Chinese coverage from Tencent News noted Baidu’s own renewed push around Tieba’s user-generated content in 2025, treating the forum as a support pillar for Baidu’s wider content platform rather than a growth engine on its own.
Cost is the third reason it still gets used. Running or seeding a Tieba bar costs a fraction of a KOL campaign on Xiaohongshu or Douyin. There are no influencer fees. The main investment is staff time: writing useful posts, answering questions honestly, and keeping the bar active enough that it does not read as abandoned.
What the numbers actually look like
Tieba is not the platform it was a decade ago, and brands should go in with clear eyes about that. Chinese reporting from early 2025, citing Tencent News, put daily active users at roughly 8 to 9 million and monthly active users around 30 million. Compare that with Tieba’s 2015 peak of close to 25 million daily active users and over 300 million monthly, and the decline is steep. Baidu’s own stated strategy for the platform involves trimming advertising to bring lapsed users back and encourage more organic posting, which tells you the platform itself sees this as a rebuilding phase, not a growth phase.
Those figures put Tieba well below Xiaohongshu, Douyin or WeChat in raw scale.
How a brand can realistically use it
Start by searching your own brand name on Tieba. If a bar already exists, read it before doing anything else. See what customers are actually complaining about, asking, or praising. Existing fan communities are more valuable as a listening post than as an advertising channel.
If no bar exists, claiming or creating one is straightforward and cheap. Set it up, post a handful of genuinely useful threads (product guides, FAQs, honest comparisons), and let it sit. Do not flood it with promotional copy. Tieba users, and Baidu’s own algorithm, both penalise content that reads as an ad rather than a discussion.
Engaging an existing fan-run bar takes more care. Reach out to the moderators, offer something of value such as product samples or accurate technical answers, and avoid taking over the tone of a community that predates the brand’s involvement. Heavy-handed corporate posting in a fan bar tends to backfire quickly.
The strongest use case remains SEO support. Pair a modest Tieba presence with a proper social media strategy across Xiaohongshu, WeChat and Douyin, and let Tieba fill the specific gap those platforms cannot: long-form, searchable, permanent discussion that Baidu itself favours.
Where Tieba fits, honestly
Tieba is not where most foreign brands should put their main budget. It will not deliver ecommerce conversions the way Douyin or Tmall livestreams can. It will not build a following at the speed Xiaohongshu can.
What it does well is quiet and cumulative: search visibility, community listening, and a low-cost presence in a corner of the internet that Baidu still rewards. Treat it as a supporting channel inside a wider Baidu SEO and social strategy, not as a campaign on its own, and it earns its keep.

About the author
I am Harry Huang, Founder of Ecommerce China Agency. I still tell clients not to write off Baidu’s older properties too fast. Tieba’s active user numbers have fallen a long way since 2015, but Baidu keeps ranking its own forum threads on page one, and that single fact keeps Tieba on our checklist for every China SEO audit we run. What surprises most foreign brands is how many fan-built bars already exist for their name before they ever set foot in the market. Reading that community first, before posting a single word, tells you more about your Chinese customers than most paid research does. If you want a proper look at where your brand stands on Baidu and across China’s platforms, get in touch with our team.
