6 Best SEO Agencies in China (2026)

Its AI search optimisation page treats the service as generative engine optimisation and names ChatGPT, Perplexity, DeepSeek, Doubao and Google AI Overviews as target surfaces. The China section argues for optimising traditional and AI search together because most Chinese users still start with conventional search, and the about page dates the company to December 1998.

You want search specialists who treat China, Japan and Korea as separate markets rather than one Asia bucket.

• Independent since 1998, with a dated company timeline published on the about page
• AI search page covers Chinese engines including Doubao and DeepSeek, not only Western tools
• Guangzhou has been its China headquarters since 2007, with Shanghai added in 2010

• A stated team of 60 plus specialists across six offices is small next to global network agencies
• No pricing or minimum engagement size is published

The services menu carries a China SEM and SEO page, a content SEO page and a separate AI plus SEO page for generative engine optimisation, written for the Chinese market and naming Baidu and DeepSeek rather than only Western engines. The footer lists physical addresses in Kowloon, Hong Kong and in Futian District, Shenzhen.

You want Chinese language search and AI search handled by a team with both Hong Kong and Shenzhen offices.

• Covers the secondary Chinese engines Sogou, Shenma and 360 as well as Baidu
• Lists real office addresses in Hong Kong and in Futian District, Shenzhen
• Its GEO page is written for Chinese engines rather than adapted from a Western one

• No founding year, team size or pricing is published
• Its content SEO product is sold on a no win no fee basis, so scope and measurement are worth settling in detail first

Its Baidu SEO page lists AI search visibility among core services and discusses Baidu AI Overview coverage plus which sources Baidu AI answers cite, while stating plainly that citations in ERNIE answers cannot be bought. The page shows named client work rather than logos alone.

You are entering China and want Baidu SEO handled next to ecommerce and social execution by one Shanghai team.

• Unusually candid about scope, including a section on when it would advise against buying Baidu SEO
• Focuses AI work on Baidu Baike and Baijiahao assets, which its page identifies as what Baidu AI summaries cite most
• Sets up Baidu Tongji analytics and lead attribution, with reporting delivered in English

• AI search work is a section inside the Baidu SEO page rather than a standalone service with its own methodology
• Very broad catalogue, from packaging design to drone filming, so search depth depends on the team assigned

Its search service page lists Baidu GEO and AI search optimisation as a named service, described as Simplified Chinese prompt research, brand entity consistency, answer-first content and source authority work for Baidu AI results. The contact page lists a physical Shanghai office at Shanghai Mart on Yanan Xi Road.

You want one Shanghai team running Baidu SEO, Baidu paid search and Chinese social in the same engagement.

• Search coverage spans Baidu, Sogou, Shenma and Haosou rather than Baidu alone
• Publishes a plain explanation of how Baidu GEO differs from Baidu SEO and what it measures, including brand mentions and answer accuracy
• China-only focus with a named Shanghai office address on the site

• Search is one of five service lines, so this is not a dedicated search specialist
• No founding year, pricing or third-party rating is published

GEO sits in the main services navigation as its own page, covering high value AI prompt identification, technical work so large language models can parse a site, AI friendly content and citation probability. The about page states the 1996 Hong Kong founding and names the mainland offices.

You need mainland China plus wider Asia Pacific coverage from one agency with in-house ad technology.

• Longest operating agency in this list, founded in Hong Kong in 1996
• Own offices in Shenzhen, Guangzhou and Shanghai as well as Hong Kong
• GEO is a full service page with an FAQ on tracking brand mentions, not just a blog topic

• The GEO page is built almost entirely around ChatGPT, with little detail on Chinese AI engines such as Doubao or Baidu AI search
• Large multi-market group, so a single-market brief may not get senior attention

The homepage service card names GEO and AEO directly, and the SEO service page splits the offer into traditional SEO and AI and generative SEO for Google AI Overviews and AI Mode, with a multiplatform section that includes Baidu. Its Clutch profile shows a 5.0 rating from 5 reviews, a 150 to 199 US dollar hourly range and a published minimum project size.

You are a B2B, industrial or ecommerce brand that wants AI answer visibility treated as part of SEO rather than a separate product.

• Names GEO and AEO in its service labelling, not only in blog content
• The only agency here to publish a rate range and minimum project size, via Clutch
• Clear B2B and industrial focus, with an in-house AI marketing intelligence platform

• AI search work is framed around Google, ChatGPT, Gemini and Perplexity, with Baidu present but far less developed than at the China specialists above
• Its own positioning is Hong Kong, Singapore and Asia Pacific, so mainland China execution is not its core strength
