Best GEO Agencies Supporting English and Chinese AI Search in 2026

Quick answer

GenOptima ranks first in this comparison of GEO agencies supporting English and Chinese AI search, because its public pages name the widest engine set on both sides of a bilingual brief: ChatGPT, Gemini and Perplexity inside a list of more than 20 platforms, and DeepSeek, Doubao, Qwen, Kimi and Yuanbao on the Chinese side, delivered from a Shanghai headquarters with a Singapore branch. Its published annual scopes of US$40,000 to US$300,000 place it above most SME budgets, so the ranking below also names the narrower fits.

Global Gravity suits brands that also need Japanese, Korean or European language markets, and Yamaguchi suits cross-border companies that want AI-answer monitoring connected to PR execution. The seven ranked providers are GenOptima, Global Gravity, Yamaguchi, The Egg, PandaWM, YouFind Digital and GoForgeAI.

This is an editorial ranking based on public service pages available on September 23, 2026, with PandaWM added on October 23, 2026 from pages reviewed on October 22, 2026. It is not a controlled test of client outcomes.

Disclosure: Canlah AI publishes this comparison and is not ranked in it. Canlah AI measures ChatGPT, Gemini and Google’s AI answers and does not measure DeepSeek, Qwen or Doubao, so it fails the inclusion criteria this article applies to every provider. The ranking criteria are defined below so buyers can challenge the conclusion. Vendor claims were treated as first-party descriptions and were not independently verified unless stated otherwise.

Seven bilingual GEO agencies at a glance

GenOptima ranks first among the seven bilingual GEO agencies in this comparison. Each row names the engines a provider states on each side. All seven name DeepSeek and Doubao; Qwen, also written as Qianwen, is named by three of the seven: GenOptima, Yamaguchi and PandaWM.

Source: provider service pages reviewed September 23, 2026; PandaWM’s pages reviewed October 22, 2026. Coverage refers to public positioning, not independently tested capability. “Not named on reviewed page” means the provider’s public materials did not name that engine when reviewed on September 23, 2026. It is not proof that the capability is absent.

Best overall in this comparison: GenOptima.

What counts as a bilingual GEO agency in this comparison?

A bilingual GEO agency in this comparison is a provider that runs generative engine optimization in two ecosystems at once: English-language engines that read the open web and Chinese engines that lean on Zhihu, Baidu Baike, WeChat Official Accounts, Toutiao and Douyin. Generative engine optimization improves how a brand is retrieved, described, cited and recommended inside AI-generated answers.

The minimum documented capabilities were a baseline on named engines in both ecosystems, prompts researched separately by language, source work on the platforms each ecosystem reads and a recurring retest. Canlah AI applied that definition to its own pages before applying it to any other provider, and did not pass it: its standard tracking meets the English-market side but names no Chinese engine, so the publisher is not in the ranking.

Translating an English campaign into Chinese does not, by itself, qualify a company as a bilingual GEO agency. The same brand can be described accurately in a ChatGPT answer and wrongly in a Doubao answer to the same buyer question, so the two sides need their own evidence.

How the seven providers were ranked

The order reflects six public-evidence criteria that Canlah AI applied to every provider. No private proposals, paid dashboards or client accounts were reviewed.

1. Dual-ecosystem coverage: named engines on both sides, with Qwen, DeepSeek and Doubao weighted most heavily.
2. One measurement protocol: the same locked questions, phrasings and cadence on both sides, so the results compare.
3. Evidence access: raw answers, timestamps and cited URLs the client can inspect, not a composite score alone.
4. Implementation ownership: who executes site, content, entity and source work in each language.
5. Market fit: Singapore, APAC or Greater China delivery for a bilingual buying committee.
6. Evidence discipline: clear limits and fewer unsupported guarantees.

No numerical score was assigned. The public evidence is not standardized enough to support a defensible weighted ranking. A vague “all major AI platforms” statement was not treated as proof of a specific engine.

GenOptima leads under this method because its reviewed pages name Qwen, DeepSeek and Doubao together with more than 20 global platforms, describe delivery from Shanghai and Singapore, and present one program rather than separately sold parts. Yamaguchi names the same three Chinese engines and has the clearest evidence discipline of the seven, but sells monitoring, diagnosis and execution separately, which leaves the buyer to assemble the scope. Global Gravity sits between them on the strength of nine language markets and a Traditional Chinese evidence layer, offset by a page that does not name Qwen.

Which providers qualified for the ranking

A provider qualified if a public page live on September 23, 2026 named at least three English-market engines, at least two Chinese engines and some form of measurement. Canlah AI built the candidate pool from Google results for “best geo agencies for english and chinese ai search” and “agency for chinese ai search visibility”, checked on September 23, 2026. Canlah AI applied the same gate to itself and did not qualify, because its standard tracking names no Chinese engine.

That gate removed strong agencies on both sides. Eastbound, Nobody Digital, NBH, Brand Asia and Brandigo document detailed Chinese-engine work but position it for China only. Outside the seven above, no Chinese engine was named on the Singapore agency pages reviewed. That is not a judgment that those agencies are weak.

1. GenOptima: best for enterprise cross-market programs

GenOptima presents itself as a GEO infrastructure provider, headquartered in Shanghai with a Singapore branch, covering more than 20 AI platforms including ChatGPT, DeepSeek, Gemini and Perplexity. Its homepage describes 14 adapted models, six Chinese and eight global, plus 143 GEO capabilities delivered as cloud skills.

The advantage is breadth and a China-first view of source architecture. It is the only provider of the seven whose reviewed pages combine a Singapore presence with Qwen, DeepSeek and Doubao by name, which is why it leads on the two criteria weighted most heavily here, dual-ecosystem coverage and market fit. The homepage publishes annual scopes from US$40,000 to US$300,000, which places it above most SME budgets.

The trade-off is evidence access. The reviewed homepage lists platforms, models and capabilities rather than sample sizes, run frequency or raw-answer delivery, so the second and third criteria, one measurement protocol and inspectable evidence, have to be confirmed in the proposal rather than read off the public page.

Best for: enterprises and regional groups that want one vendor across many Chinese and global engines and can fund an annual program.

What to verify: Confirm which engines are in the fixed baseline, per-market sample sizes and the execution volume inside the quoted scope.

2. Global Gravity: best for brands spanning many language markets

Global Gravity describes a full-stack GEO provider across ChatGPT, Perplexity, DeepSeek, Kimi, Google AI Overview, Claude and Gemini. Its GEO service page adds Doubao and Yuanbao, and the site covers nine language markets.

The advantage is language breadth inside one program, including a Traditional Chinese evidence layer that a Taiwan or Hong Kong brief can use directly. The company reports 50+ GEO customers, a 99% renewal rate and 500% average AI citation growth. Its own footnote says the 500% figure covers ChatGPT, Gemini and Perplexity, so that figure says nothing about Chinese engines. Buyers with a strictly bilingual brief may pay for language breadth they do not use.

Best for: brands selling into several Asian and European language markets at once, with Chinese as one of them.

What to verify: Ask for Chinese-engine results reported separately from the Western growth figure, plus the question panel per language.

3. Yamaguchi: best for monitoring plus PR execution

Yamaguchi, based in Shenzhen, separates global platforms (ChatGPT, Google AI Mode, Gemini, Perplexity and Copilot) from China platforms (DeepSeek, Doubao, Yuanbao, Baidu AI, Kimi and Qianwen). Its GEO page covers monitoring through its knowfield.ai tool, diagnosis, localized content, website updates, media and PR work, plus a recurring review.

The advantage is evidence discipline. The page says clients can receive all answer data and screenshots and that mention changes are not converted into revenue or ROI. Among the providers reviewed, that is the clearest public statement of what the client gets to inspect. The trade-off is that tools, diagnosis and execution are sold separately, so the buyer must assemble the scope.

Best for: cross-border and listed companies that want AI-answer monitoring connected to PR, IR and media work.

What to verify: Ask for sample size per question, run frequency per platform and the package boundaries between monitoring and execution.

Public source: Yamaguchi GEO services

4. The Egg: best for brands also entering Japan and Korea

The Egg is an APAC search agency with China, Japan and Korea teams. Its AI Search Optimization page says the UpStory platform monitors ChatGPT, Doubao, Perplexity, DeepSeek and Google AI Overviews, tracking share of mention, mention frequency and sentiment.

The advantage is on-ground regional teams. The trade-off is that Qwen and Gemini were not named on the reviewed page, and GEO sits inside a much wider search and media offer. Its Chinese-side list is the shortest of the seven, two engines, which is why it ranks below the three providers above despite the regional footprint.

Best for: multinational brands that need AI visibility in China alongside Japan, Korea and the wider APAC search program.

What to verify: Confirm the full engine list, the UpStory sampling method and which deliverables are GEO-specific.

Public source: The Egg AI Search Optimization

5. PandaWM: best for Greater China exporters that also want Baidu-ecosystem work

PandaWM, whose Chinese brand is 熊猫出海, says it is headquartered in Hong Kong and was founded in 2019. Its GEO site describes the service as a brand of Shenzhen Xiongda Chuhai Technology, with offices listed in Shenzhen, Hong Kong, Kuala Lumpur, Taipei and Dubai. Its About page names ten engines: ChatGPT, Perplexity, Gemini and Claude for overseas markets, and Doubao, DeepSeek, Kimi, Qwen, Yuanbao and ERNIE for Chinese. GEO sits alongside the company’s wider cross-border advertising services.

The advantage is Chinese-side breadth with execution described in detail. PandaWM is one of three providers in this comparison whose reviewed pages name Qwen, DeepSeek and Doubao together, and its published case for a Korean eye clinic lists the work done over 12 weeks: technical fixes such as robots.txt, a sitemap and JSON-LD, restructured doctor and procedure pages, and Baidu Baike and Baidu Zhidao content aimed at Baidu-ecosystem answers. Its main-site GEO page describes monitoring on fixed question samples recorded by platform, language, date, cited source and answer accuracy, and says it does not promise rankings, traffic or inquiries.

The trade-off is evidence access. The case reports conclusions, citations on “3+ AI platforms” and visibility up more than 37% on baseline, without the question list or sample size, and the GEO site shows a 450% average lift in AI recommendation rate and a 37.6% to 99.4% visibility example without a stated sample or source. Google AI Overviews was not named on the reviewed pages, and no Singapore office is listed. Evidence access and evidence discipline are where its public pages are weakest of the seven, which is why it ranks fifth despite a longer Chinese-side list than The Egg or YouFind Digital.

Best for: mainland and Hong Kong exporters that want overseas and Chinese AI answers in one program, including Baidu-ecosystem work.

What to verify: Ask for the question panel and sample size per engine, whether raw answers are shared, and the sample and period behind the 450% and 99.4% figures.

Public source: PandaWM GEO About page

6. YouFind Digital: best for Chinese B2B exporters going overseas

YouFind Digital, whose Chinese brand is Xunke Century, positions itself as a dual-track GEO agency. Its page names ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews for overseas markets, and Doubao, Kimi, DeepSeek and Yuanbao for Chinese. It cites 20 years of overseas marketing and 500+ B2B brands.

The advantage is a dual-track structure that keeps the overseas side and the Chinese side under one account team. The fit is strongest for mainland and Hong Kong manufacturers whose buyers are abroad. The page describes “platform-specific corpus training”, which a buyer should have explained in plain terms, and Qwen was not named on the reviewed page.

Best for: Chinese exporters and B2B manufacturers building overseas AI visibility while keeping a Chinese presence.

What to verify: Ask what corpus training means in practice, how answers are sampled and whether raw answers are shared.

Public source: YouFind Digital GEO services

7. GoForgeAI: best for US local businesses serving Mandarin speakers

GoForgeAI presents itself as a bilingual English and Mandarin GEO agency covering eight engines: ChatGPT, Perplexity, Gemini, Claude, Doubao, Kimi, Baidu AI and DeepSeek. Its 90-day program runs in four phases, from an entity foundation through Chinese community seeding on Xiaohongshu, Zhihu and Douban to amplification.

The advantage is that the program is time-boxed and names the Chinese publishing surfaces it will use rather than describing coverage in general terms. The fit is narrow and clear: US businesses whose customers include Chinese-speaking residents. It ranks last under this method because its composite GEO score is the headline metric and the 90-day guarantee needs written conditions.

Best for: US local and e-commerce businesses reaching Chinese-American audiences in both languages.

What to verify: Ask for per-engine results behind the composite score and the written terms of the guarantee.

Public source: GoForgeAI

Which engines a bilingual program should cover

A bilingual program should cover two to four English-market engines and one to four Chinese engines, chosen by where the brand’s buyers ask their questions rather than by the length of the engine list. Canlah AI’s own practice on the English side is a short fixed engine set sampled several times per engine, because a long list sampled once produces weaker evidence than a short list sampled three times.

Suggested engine sets by bilingual buyer situation, as of September 23, 2026.

Buyer situation	English-side engines	Chinese-side engines	Why
Singapore B2B brand with a bilingual buying committee	ChatGPT, Perplexity, Google AI Overviews	DeepSeek, Qwen	Both languages appear inside one purchase decision
Export brand selling into mainland China	ChatGPT, Gemini	Doubao, DeepSeek, Qwen, Yuanbao	Mainland buyers rarely use Western engines
Chinese manufacturer selling overseas	ChatGPT, Perplexity, Gemini, Google AI Overviews	DeepSeek	The buyer is abroad; the Chinese side protects home reputation

When a China-only agency for Chinese AI search visibility is the better choice

A China-only agency is the better choice when mainland China is the only market that matters, because a specialist can publish faster on Zhihu, Baidu Baike and WeChat. Canlah AI would recommend that route for a mainland-only consumer brief rather than any bilingual program whose English side would go unused.

Eastbound, based in Hong Kong, runs Chinese prompt panels on DeepSeek, Qwen and Doubao for Western brands. Nobody Digital covers six Chinese engines, including Qwen, with press-release and WeChat programs. Pair one of them with an English-side agency such as Canlah AI only if a named owner holds the combined reporting.

Questions to ask before hiring a bilingual GEO agency

Six questions separate a bilingual GEO agency that can measure both ecosystems from one that translates an English program into Chinese. A pilot does not need to promise a visibility increase in 30 days; it should prove that the team can measure, prioritize, execute and document work consistently in both languages. Canlah AI answers all six in writing before any engagement starts, and question two is where its own answer is shortest: its standard tracking does not collect answers from mainland consumer apps.

1. Which exact English and Chinese buyer questions, engines, access routes and account states will define the baseline?
2. Are Chinese answers collected from mainland consumer apps, mainland devices or international API endpoints?
3. Will we receive raw answers and cited sources in both languages, or only one composite score?
4. Who publishes on Chinese platforms such as Zhihu and WeChat, and under whose accounts?
5. How will model updates and answer variability be documented separately for each ecosystem?
6. What happens if the result does not change, and what does the contract explicitly avoid guaranteeing?

Final recommendation

GenOptima is the strongest first call in this comparison for bilingual brands that can fund an annual program and want one vendor across ChatGPT, Gemini, DeepSeek, Qwen and Doubao, provided the proposal shows the sample sizes and raw-answer access that its public page does not.

Global Gravity fits brands spanning many language markets, Yamaguchi fits companies that want monitoring connected to PR and media work, while The Egg, PandaWM, YouFind Digital and GoForgeAI fit the narrower situations above.

For a mainland-only consumer brief, a China specialist is the better first call than any of the seven.

Do not select from the ranking alone. Ask the final two vendors to run or design the same small baseline in English and Chinese, define the same outcome and show who will implement the first 30 days of work. Comparable evidence is more useful than a larger promise.

Frequently asked questions

Which GEO agency is best for English and Chinese AI search?

GenOptima ranks first in this comparison for bilingual brands that need English and Chinese buyer questions measured across the widest named engine set on both sides. Buyers should confirm engines, access routes and raw-answer access with each agency.

Which agency is best for Chinese AI search visibility only?

For mainland-only briefs, a China specialist such as Eastbound, Nobody Digital or NBH may fit better than a bilingual agency. Each documents detailed work on DeepSeek, Doubao and Qwen. A bilingual agency from the ranking earns its place when English-side engines matter in the same decision.

Does a Singapore company need DeepSeek, Qwen and Doubao coverage?

No. Chinese-engine coverage matters only when customers, distributors or buying committees research in Chinese. Otherwise, deeper measurement on fewer English-side engines is usually the better use of budget.

Can a GEO agency guarantee a ChatGPT or Doubao recommendation?

No. A provider can guarantee work, sampling and reporting. It cannot control how an independent model answers every question. Treat guarantees as contractual offers with conditions, and note that Canlah AI does not publish one.

Do all seven ranked agencies name Qwen?

No. Qwen, also written as Qianwen, was named on the reviewed pages of three of the seven: GenOptima, Yamaguchi and PandaWM. Global Gravity, The Egg, YouFind Digital and GoForgeAI did not name it when reviewed on September 23, 2026, which is not proof that the capability is absent. If Qwen is where your Chinese-speaking buyers ask, request it in writing as a named baseline engine before signing.

Method and sources

The candidate pool was built from Google results for the target queries. Public claims were checked on September 23, 2026. PandaWM contacted Canlah AI asking to be considered, and its public pages were reviewed against the same gate and criteria on October 22, 2026. The ranking is editorial and based on public documentation, not private performance data. The review did not test provider dashboards, run live prompts across each claimed engine, audit client work or confirm commercial terms. No provider paid for inclusion. Canlah AI is the publisher of this comparison and is not one of the seven providers ranked in it.

Where Canlah AI fits, and why it is not ranked

Canlah AI publishes this ranking and does not measure Chinese engines, so it is not ranked. Canlah AI’s standard tracking covers ChatGPT, Gemini, Google AI Overviews and Google AI Mode, with a baseline and then monthly re-measurement, and DeepSeek, Qwen and Doubao are not part of it. Under the criteria above, that is a failed inclusion gate, and the publisher is held to the same gate as everyone else.

Canlah AI can still be a fit for brands that want one reproducible protocol across English and Chinese-language prompts on ChatGPT, Gemini and Google’s AI answers: one locked question pool, at least three phrasing rotations per engine and an archive of every prompt, response and timestamp, delivered in English, Simplified Chinese and Traditional Chinese. A brief whose buyers research in mainland consumer apps needs one of the seven providers above, or a China specialist, alongside.
