Weibo Email Scraper

Weibo Email Scraper for Chinese KOL and Brand Contact Discovery

The Weibo Email Scraper is an Apify Actor that collects publicly indexed contact emails from Sina Weibo and returns them as a structured dataset. It exists because finding a 商务合作 (business cooperation) address on Weibo by hand is slow, repetitive work.

Rather than logging into the platform, the Weibo Email Scraper builds Google queries with the site:weibo.com OR site:weibo.cn operator and parses the result blocks. Everything it extracts is already public in Google's index.

Weibo is where Chinese KOLs, MCN agencies, brand accounts and media outlets publish a cooperation mailbox in their bio or pinned post. The Weibo Email Scraper is tuned to surface exactly those patterns.

You supply keywords, an optional location and the email domains that matter. You get back account names, profile URLs, bio snippets and normalised, deduplicated email addresses.

Who this Weibo email extractor is for

Brands planning influencer campaigns in mainland China. Agencies building KOL media lists. Cross-border e-commerce teams sourcing partners. Researchers mapping how a vertical presents itself on Chinese social media.

Key Features of the Weibo Email Scraper

Feature	What it means in practice
Google-based contact discovery	The Weibo Email Scraper reads publicly indexed weibo.com and weibo.cn results — no login, no cookies, no browser
Dual-domain targeting	Both the desktop and mobile Weibo domains are searched in one query
Query expansion	Each keyword runs as a base query, a quoted query, an intitle: query and one variant per modifier
Domain-filtered extraction	Only emails on your customDomains list are kept, so you can target @qq.com or @163.com
Global deduplication	Every address is deduplicated across all queries and pages in the run
Email normalisation	Handles name [at] domain [dot] com, name (at) domain, name @ domain.com, zero-width characters and the full-width ＠ common in Chinese text
Junk filter	Rejects placeholders such as email@, yourname@, test@, xxx@ and single-character locals
Boundary-correct matching	@gmail.com will not match inside @gmail.company or @gmail.com.br
Soft-wrap repair	Drops a hit that is only the tail of another address in the same result block
Concurrency control	An asyncio worker pool runs several queries in parallel with a shared stop signal
Retry logic	Up to 3 attempts per page with exponential backoff and a fresh proxy session per request
Block detection	CAPTCHA, "unusual traffic" and consent pages are detected and retried, not treated as empty
Resumable state	Progress is checkpointed in the key-value store and survives PERSIST_STATE, MIGRATING and ABORTING events
Fallback parser	If Google's markup changes, the crawler degrades to "emails without account details" rather than "no results"
Structured output	Fourteen fields per row, exportable to CSV, JSON or Excel

The full-width ＠ handling deserves a note. Chinese-language posts frequently use full-width punctuation, and a naive regex misses those addresses entirely. The Weibo Email Scraper normalises them before matching.

How the Weibo Email Scraper Works

1. Read input. Keywords, location, email domains and limits are validated.
2. Build queries. The Weibo Email Scraper composes searches such as site:weibo.com OR site:weibo.cn 美妆 商务合作 "@qq.com".
3. Fetch search results. Pages are requested asynchronously through the Apify GOOGLE_SERP proxy using aiohttp.
4. Parse structurally. The parser finds each <h3> title, then the smallest surrounding block — it does not rely on Google's CSS class names.
5. Extract emails. A domain-filtered regex pulls addresses from the block text, including obfuscated and full-width forms.
6. Deduplicate and store. Each unique lead is pushed to the Apify dataset immediately.

Base queries run first, so your strongest matches arrive early. Blocked or failed queries are re-queued once at the end of the run.

The Weibo Email Scraper never opens weibo.com itself. There is no browser, no JavaScript rendering, no authentication and no API key.

What Data Does It Extract?

Each dataset row pairs one email with the account metadata Google printed beside it — typically a Weibo nickname, a verified brand name or a media outlet title.

username and profileUrl are filled when Google exposes a handle such as weibo.com/somebrand. Where Google shows only a Chinese display name, you still get accountName, fullName, the snippet and the email.

Descriptions are cleaned of interface labels and engagement counters, so the bio text you see is the bio text, not "转发 1.2万 · 评论 3421".

In short, the Weibo Email Scraper gives you a contact, an identity and the evidence for both: the email itself, the account it belongs to, and the snippet it was lifted from.

Input Fields and Configuration

Field	Type	Default	Meaning
keywords	array (required)	["founder", "brand"]	Search terms — niche, job title or industry
location	string	""	Optional location phrase added to every query
customDomains	array	["@gmail.com","@yahoo.com"]	Only emails on these domains are kept; the @ is optional
maxEmails	integer 1–10000	20	Stop after this many unique emails
countryCode	string	""	Two-letter country for the search proxy (US, GB, DE...)
expandQueries	boolean	true	Search each keyword × domain pair in several phrasings
queryModifiers	array	["email","contact","business","cooperation"]	Extra words combined with each keyword when expansion is on
maxPagesPerQuery	integer 1–50	30	Pagination cap per query
maxConcurrency	integer 1–20	5	Parallel queries

Using countryCode with the Weibo Email Scraper

countryCode matters more on Weibo than on almost any other platform in this family. Google's index of Chinese social content varies noticeably by search region.

Try HK, TW, SG and US in separate runs. Hong Kong and Singapore searches often surface cross-border commerce and overseas Chinese accounts that a US-region search does not return.

Run the Weibo Email Scraper across several country codes and merge the exports. Deduplication is per run, so overlap between runs is easy to remove afterwards.

Choosing the right email domains

The defaults are @gmail.com and @yahoo.com, which are not the Chinese norm. Weibo accounts overwhelmingly publish @qq.com, @163.com, @126.com, @sina.com, @sina.cn and @foxmail.com addresses.

Setting customDomains to those providers is the single biggest change you can make to the Weibo Email Scraper's yield. Add @gmail.com alongside them if you are targeting internationally-facing brands.

Choosing keywords

Keywords go into the Google query verbatim, so Chinese input works exactly as well as English. 美妆, 母婴, 健身教练, 品牌方, MCN and 探店 are all valid.

Pair Chinese keywords with the default modifiers, or replace the modifiers with 商务, 合作, 邮箱 and 联系 for a fully Chinese-language expansion set.

Output Schema and Dataset Fields

Field	Meaning
network	Platform name
keyword	The keyword that produced the lead
query	The exact Google query used
title	Raw result title
accountName	Account label Google prints (handle or display name)
fullName	Display name parsed from a profile-style title; empty for post captions
username	URL-safe handle when Weibo exposes one; otherwise null
profileUrl	Canonical account URL when a handle is known; otherwise empty
url	Direct platform link when exposed, else the profile URL
description	Bio or caption snippet, cleaned of labels and counters
email	Lower-cased email address
emailDomain	The matched domain, e.g. @qq.com
possiblyTruncated	true when Google's snippet ellipsis touched the email — verify before sending
foundAt	ISO 8601 UTC timestamp

Because query and keyword are stored on every row, the output is fully auditable. You can see which phrasing found which KOL and tune the next run accordingly.

How to Use the Weibo Email Scraper

1. Open the Weibo Email Scraper on Apify and click Try for free.
2. Enter two or three specific keywords — a niche beats a broad category.
3. Replace customDomains with the Chinese mail providers listed above.
4. Set countryCode to HK, TW, SG or leave it empty and compare.
5. Set maxEmails to the list size you actually need.
6. Run it, then export the dataset as CSV, JSON or Excel.

Leave maxPagesPerQuery and maxConcurrency at their defaults for a first test. You can raise concurrency later if your Apify plan has the memory headroom.

The Weibo Email Scraper can also be triggered from the Apify API or SDK clients, which makes recurring KOL discovery runs easy to schedule.

Use Cases for the Weibo Email Scraper

Use case	How the Weibo Email Scraper helps
KOL and influencer sourcing	Find creators who publish a 商务合作 mailbox in their bio

China-focused campaigns rarely stop at one network. Pair the Weibo Email Scraper with the Zhihu Email Scraper for long-form expert voices and the WeChat Email Scraper for official-account publishers.

If your campaign also covers Western creators, the Instagram Email Scraper uses the identical input schema, so the workflow you build around the Weibo Email Scraper transfers without changes.

Why Use This Weibo Email Scraper

Generic email crawlers point at arbitrary websites and hope. This one is a purpose-built Weibo scraper: the domain list, username pattern, profile URL template and query modifiers are all configured for Sina Weibo.

Parsing is structural rather than cosmetic. Because the Weibo Email Scraper locates the <h3> and walks outward, a Google layout change degrades quality instead of breaking the run.

Chinese-text handling is deliberate. Full-width at signs, zero-width characters and [at] obfuscation are all normalised before matching, which is where most generic extractors lose leads on Chinese content.

Runs are resumable and checkpointed, and every row tells you whether the snippet may have truncated the address.

Finally, the Weibo Email Scraper is transparent about its method. It reads Google, it says so, and it stores the exact query on every lead so you can reproduce any result yourself.

Limitations of the Weibo Email Scraper

Please read this before buying. These constraints are real.

• Only publicly indexed emails. The Weibo Email Scraper finds addresses already visible in Google's index. Private data and login-gated content are out of reach.
• Google caps a single query at roughly 300 results. Query expansion exists to work around that ceiling.
• Google indexes Weibo far less completely than Western networks. Chinese platforms are thinly crawled, much of the indexed content is in Chinese, and coverage shifts over time. Expect lower volume than an Instagram or Facebook run.
• username and profileUrl may be empty. They are only populated when Google exposes a handle. Some rows carry accountName and fullName only — a Google limitation, not a bug.
• possiblyTruncated: true means verify. Google's snippet ellipsis may have clipped the address.
• Requires the Apify GOOGLE_SERP proxy. The Actor cannot run without Apify proxy credentials.
• Free Apify plans are capped at 100 emails per run. Paid plans are uncapped.
• No volume guarantee. Results vary with keywords, domains, country code and location.

The Weibo Email Scraper is not affiliated with, endorsed by or connected to Sina Weibo. Use the output in line with PIPL, GDPR and your own outreach policy.

Example Run

A realistic Weibo Email Scraper input for beauty-category KOL sourcing:

{
  "keywords": ["美妆博主", "护肤", "brand"],
  "location": "上海",
  "customDomains": ["@qq.com", "@163.com", "@sina.com", "@foxmail.com"],
  "maxEmails": 250,
  "countryCode": "HK",
  "expandQueries": true,
  "queryModifiers": ["email", "contact", "business", "cooperation"],
  "maxPagesPerQuery": 30,
  "maxConcurrency": 5
}

One dataset item from that run:

{
  "network": "Weibo",
  "keyword": "美妆博主",
  "query": "site:weibo.com OR site:weibo.cn 美妆博主 cooperation \"@qq.com\" \"上海\"",
  "title": "小鹿美妆日记 (@xiaolu_beauty) 的微博_微博",
  "accountName": "xiaolu_beauty",
  "fullName": "小鹿美妆日记",
  "username": "xiaolu_beauty",
  "profileUrl": "https://weibo.com/xiaolu_beauty",
  "url": "https://weibo.com/xiaolu_beauty",
  "description": "上海美妆博主 / 护肤测评。商务合作请联系 xiaolu.pr@qq.com",
  "email": "xiaolu.pr@qq.com",
  "emailDomain": "@qq.com",
  "possiblyTruncated": false,
  "foundAt": "2025-03-14T09:41:22Z"
}

Every row the Weibo Email Scraper writes contains all fourteen fields, so the JSON shape is stable and safe to map into a database schema.

Weibo Email Scraper FAQ

What is the Weibo Email Scraper?

An Apify Actor that extracts publicly indexed contact emails from Sina Weibo search results and returns them as a structured dataset.

Does the Weibo Email Scraper log into Weibo?

No. It never opens weibo.com, never authenticates and never uses Weibo's API. All data comes from Google search results.

Can it scrape private Weibo accounts or hidden emails?

No. If an address is not publicly visible in Google's index, the Weibo Email Scraper cannot find it.

Which email domains work best for Weibo?

@qq.com, @163.com, @126.com, @sina.com, @sina.cn and @foxmail.com are the highest-yield choices for mainland Chinese accounts.

Do Chinese-language keywords work?

Yes. Keywords are inserted into the Google query as written, so 美妆 and 商务合作 behave exactly like English terms.

Does it handle the full-width ＠ used in Chinese posts?

Yes. Full-width at signs, zero-width characters and [at] style obfuscation are all normalised before matching.

Why do I get fewer results than from a Western platform?

Google's index of Weibo is much thinner than its index of Facebook or Instagram. That is the main constraint on volume, and no scraper can add pages Google never crawled.

What does possiblyTruncated mean?

Google's snippet ellipsis may have clipped the email. Verify those rows before sending.

Why are some username and profileUrl values empty?

Google sometimes prints only a Chinese display name with no handle. The Weibo Email Scraper fills those fields when a handle is exposed and leaves them empty otherwise.

Does the Weibo Email Scraper need a proxy?

Yes. It requires the Apify GOOGLE_SERP proxy and cannot run without Apify proxy credentials.

How many emails can I collect per run?

Free Apify plans are capped at 100 emails per run. Paid plans are uncapped, up to the maxEmails value you set (maximum 10000).

Can I run the Weibo Email Scraper on a schedule?

Yes. Use Apify Schedules or the API. Runs are resumable and state is checkpointed in the key-value store.

What export formats are supported?

The Weibo Email Scraper writes to a standard Apify dataset, which exports to JSON, CSV, Excel, XML and HTML.

Is the Weibo Email Scraper affiliated with Sina Weibo?

No. It is an independent Apify Actor with no affiliation with or endorsement from Weibo.
