Baidu decides the brief, not Google
Almost everything a foreign marketer knows about organic search assumes one engine, and that assumption breaks the moment you start selling to buyers who live here. Baidu holds the bulk of desktop and mobile web search, with Sogou, Shenma and Qihoo taking the remainder, and each of them indexes differently, weights differently and rewards different things. Baidu is noticeably more literal about keyword presence in titles and headings, more suspicious of pages that load slowly from abroad, and far more generous to content that sits inside its own properties such as its encyclopedia and question boards. A strategy copied from an international playbook will rank nothing.
The second structural difference is that search is not confined to a browser. A large share of product and brand discovery happens inside apps, where Weixin articles, Douyin clips and Xiaohongshu posts are searched directly and never appear in the open web index at all. Any proposal that treats the website as the only surface is describing a fraction of the demand. Ask a prospective agency to show you, for a competitor in your category, where the visibility actually is. If they only show you web rankings, they have not looked.
Filing and hosting are a licensing question before they are a technical one
To host a site on domestic servers you need an ICP filing, and the filing requires a registered local entity with a local contact. Without it, hosting stays offshore, which means every request crosses a heavily filtered network boundary and page load times collapse to a level Baidu treats as a quality signal against you. This single dependency reorders the entire project plan: the legal and entity work has to start months before anyone argues about title tags.
Agencies handle this in different ways, and the differences matter to you. Some will file under their own entity, which is fast and leaves you dependent on them for the life of the domain. Some will run the site from an offshore edge network tuned for the crossing, which is legitimate and slower. Some will build inside a platform account instead of a website, which sidesteps filing entirely and gives you no asset you own. Ask which route is being proposed, who holds the filing, and what happens to it if the relationship ends. The answer to that last question is where the leverage lives.
Content has to be written, not translated
Machine translated simplified Chinese reads as machine translated simplified Chinese, and buyers here abandon it instantly. Beyond tone, the vocabulary problem is real: the terms your customers type are often not the official terms your industry uses in English, brand names have local renderings that may or may not be the ones you registered, and segmentation words differ from the ones in your global keyword set. Research has to be done natively in the language from engine suggestion data, not translated from an English list.
There is also a legal filter on the words themselves. Advertising rules prohibit superlative claims, so the absolute language that fills Western landing pages, phrases claiming to be the first, the best or the national leader, creates genuine exposure rather than merely sounding boastful. Good local teams draft around this automatically. If a proposal promises you copy full of superlatives, the people writing it have never been reviewed by a local compliance team.
What working with an SEO agency in Beijing gets you that a remote vendor cannot
The capital concentrates the buyers who need the most careful handling: state owned enterprises, ministries and their suppliers, universities and research institutes, large technology firms and the education sector. Selling into any of them involves procurement processes, documentation expectations and a tolerance for formality that a remote vendor will underestimate. Agencies based here know what a tender response has to look like and how long an approval chain takes, and they build content calendars that survive contact with it.
Physical presence also matters for the parts of the job that require identity verification, platform account opening, payment through domestic channels and relationships with publisher and platform representatives. These are not glamorous capabilities, but they are the ones that stall a launch. Ask who on the account holds those relationships personally, and what happens if that person leaves.
Measurement runs on a different stack
The analytics and console tools you rely on elsewhere either do not report reliably from inside the network or do not cover the engines that matter. Domestic web analytics platforms and Baidu's own webmaster tools fill the gap, and they define metrics differently enough that dashboards will not reconcile with your global reporting. Decide early whether local performance will be reported into the same system as the rest of your markets, because retrofitting that later is expensive.
Insist on account ownership in whatever stack gets chosen, and insist that submission and indexing tools are registered to you rather than to the agency. Also agree what counts as a conversion when the journey ends in a messaging app rather than on a form, which is the normal path here. Reporting that stops at the website will systematically understate everything that is working.
Paid placement, platform seeding and where the risk sits
Coverage and visibility can be bought here in ways that are openly priced, from sponsored articles to seeded question and answer threads to volume posting on social platforms. Some of this is ordinary paid media that should simply be labelled as such. Some of it is fabricated engagement that platforms actively penalise and that buyers increasingly recognise. The difference is not always obvious in a proposal, so make the rule explicit at the start: every placement in a report is marked paid or earned, and nothing is published in your brand's name without approval.
Apply the same discipline to link acquisition. Domestic link markets exist, they are cheap, and the sites in them are usually worthless. Reference material published on industry association sites, genuine partnerships and useful local research do more for a serious brand than a thousand purchased placements.
Building a shortlist you can actually compare
Give three firms the same one page brief with your entity status, your hosting situation and your commercial goal stated plainly, then read what each of them asked you rather than what each of them promised. A team that immediately asks about your filing status and your local legal entity understands the sequencing. A team that opens with a keyword list has skipped the part that determines whether the project is even possible.
Search work here rarely stands alone, so it is worth reviewing the adjacent local digital marketing teams and the platform specialists who handle in app discovery at the same time, and the wider search agency category gives you a baseline for how firms describe themselves elsewhere. Once your shortlist is down to three, ask them for comparable proposals so you are judging scope and staffing rather than the quality of the deck.
