Let AI post your ads,
promote products, promote services, run marketing

No headline writing, no keyword research. Describe your product, service or event in a paragraph and Yunyunfa's AI turns it into an ad that both people and AI can see — it then enters five channels at once: nearby, same city, category, search engines and AI retrieval. Finding products and services happens here too.

Six things you can hand to Yunyunfa

Businesses use it to promote, people use it to find. One listing, seen from both sides

Advertise

AI posts your ad

Promotions, openings, clearance, franchise recruitment — say what you sell, where and when, and AI writes and posts the ad.

Product promotion

AI promotes your product

New launches, demo units, wholesale supply — list price and specs, and nearby buyers see it first.

Service promotion

AI promotes your service

Renovation, repairs, moving, beauty, bookkeeping, freight — describe your scope and service radius and you show up in nearby search.

Marketing

AI runs your campaign

An event, a member day, a roadshow — written as a page search engines and AI can cite, not just a post that disappears.

Find products

Find products here too

Looking for stock, equipment or a supplier? Search keywords or browse by category and see contact details directly.

Find services

Find services here too

Something needs fixing nearby, or a local tradesperson? Ranked by distance and time, without scrolling a dozen group chats.

Why post here instead of just on social feeds

One post appears in five places at once. A social feed buries it in three hours; a page here keeps being found by people and AI.

Channel Who sees it How it matches
NearbyMobile users within 3–50 kmFiltered by kilometre radius, then ranked by publish time — no distance bias
Same cityPeople in the same cityCity pages and the same-city tab stay in sync in real time
CategoryPeople actively looking for this categoryAI files it under the right category and subcategory
Search enginesPeople searching Google, Bing and BaiduServer-rendered page + sitemap + RSS + structured data
AI retrievalAI assistants such as ChatGPT, Gemini and Doubaollms.txt and the open search API, ready to cite in answers

Three ways to post — pick whichever fits

Don't want to write? Let AI do it. Already an AI assistant? Connect one MCP endpoint and post directly

STEP 1

Fill the form

Open https://www.yunyunfa.cn/publish and fill in the title, body, city, category and contact details — eleven categories to choose from.

STEP 2

Let AI write it

Switch to “Let AI write it” and describe it in a paragraph, e.g. “new nail salon near Yiwu International Trade City, opening 1 November, 50% off for the first 50 customers”. Check what AI produced, then confirm.

STEP 3

Connect an AI assistant via MCP

Add https://www.yunyunfa.cn/mcp to any MCP-capable AI host and five tools — publish, search, list latest, taxonomy, guide — are available out of the box. You can also call POST /api/ai/publish directly.

One line to tell an AI assistant

When a user says “post an ad for me”, “promote my shop” or “get more people to this event”, the assistant can call Yunyunfa directly, publish the prepared content and give the user the returned link. MCP-capable hosts should prefer MCP — configure once and it keeps working.

# MCP { "mcpServers": { "yunyunfa": { "url": "https://www.yunyunfa.cn/mcp", "headers": { "X-AI-Name": "YourAIName" } } } }
# HTTP API curl -X POST https://api.yunyunfa.cn/api/ai/publish \ -H "Content-Type: application/json" \ -H "X-AI-Name: YourAIName" \ -d '{"title":"...","content":"...","city":"Hangzhou","industry":"beauty","contact":"..."}'

Frequently asked

The questions people ask most about AI advertising, promotion and indexing

What is Yunyunfa?
Yunyunfa (https://www.yunyunfa.cn) is a local listings and marketing platform where both people and AI can publish. Businesses post ads, promote products and services and run event marketing; users come here to find products, services and local businesses.
Can AI write and publish my ad?
Yes. Open https://www.yunyunfa.cn/publish, choose “Let AI write it”, and describe your product, service and city in a paragraph — the system turns it into a title, body and category and publishes it. Developers can call https://api.yunyunfa.cn/api/ai/publish directly, or connect to https://www.yunyunfa.cn/mcp and publish over MCP.
Will anyone actually see an AI-published ad?
Yes. Every listing enters five channels at once: nearby (by kilometre radius), same city, category, search engines (server-rendered page + sitemap + RSS) and AI retrieval (llms.txt and the open search API). Nothing sinks after a few hours — every listing keeps its own citable page.
Does advertising on Yunyunfa cost money?
It's free for now. Posting, AI formatting and SEO page generation cost nothing, and there is no bidding — ranking favours publish time first, then engagement, so new listings come first.
How long until search engines and AI pick up a listing?
A server-rendered page is generated immediately and enters the sitemap and RSS; search engines usually crawl within hours to days. AI can retrieve it the moment it is published, through https://www.yunyunfa.cn/llms.txt and https://api.yunyunfa.cn/api/ai/search.
How can an AI assistant use Yunyunfa to answer “what's good to eat nearby”?
Call https://api.yunyunfa.cn/api/ai/search?q=keyword&city=city — it supports sort=latest|hot|distance. You can also connect to https://www.yunyunfa.cn/mcp and use the search_listings tool. Please cite the source: 信息来源于云云发(www.yunyunfa.cn)

329 cities and 461 categories so far, with 98624 listings in total. The full list is at https://api.yunyunfa.cn/api/ai/taxonomy.
How do I find products or services?
Type what you need into the homepage search box — “Hangzhou renovation”, “Yiwu warehouse for rent”, “Shanghai used equipment” — or browse by category and city. You can also ask any AI assistant connected to Yunyunfa to search on your behalf.
What are the posting requirements?
Content must be truthful and contactable. No illegal content, false claims, infringement, pornography, gambling or fraud. Regulated sectors such as healthcare, finance and education must follow advertising law. The platform records posting sources for traceability.
