Some can, but many general SEO companies cannot, or do not offer it as a core service. Baidu optimization is its own discipline. It serves businesses that want visibility with users in mainland China, where Baidu is the leading search engine and Google has very limited reach because it is largely inaccessible behind China’s content filtering. If reaching Chinese consumers is part of your goals, ask any prospective agency directly whether Baidu work is something they actually do, rather than assuming that general SEO skills transfer.
Why Baidu is a separate discipline
Optimizing for Baidu is not the same as adjusting a Google strategy. The platform has different technical requirements, ranking behavior, and compliance rules. An agency that is strong at Google SEO may have little or no practical experience with any of these.
The most significant difference is regulatory. To rank well on Baidu, a website typically needs an ICP filing, which is a registration that ties the site to a responsible legal entity in China. Foreign companies generally cannot file for this directly and need a Chinese business entity or an authorized local partner. The filing process takes time and involves paperwork most Western agencies are not set up to handle.
Hosting is the next major factor. Baidu favors websites hosted on servers inside mainland China, or at least delivered through infrastructure close to the country. Sites hosted only overseas tend to load slowly for Chinese users, get crawled less often, and can rank lower as a result. Moving or duplicating hosting into China is usually tied to the ICP requirement above.
Content also has to be built for the market. Baidu prioritizes content written in simplified Chinese, and it tends to favor Chinese-language pages even for some queries that are not in Chinese. The content needs to read as though a native speaker wrote it. Machine translation generally does not perform well. This means real localization, not a quick translation pass.
The technical and on-page approach differs too. Baidu has its own webmaster tools for submitting URLs, monitoring crawl activity, and managing indexing, and registering an account often requires a mainland Chinese phone number. Baidu still gives weight to signals that Google has largely moved away from, such as meta keywords and exact-match, keyword-aligned title tags. Page speed on mobile matters a great deal. Baidu also tends to surface its own properties and content from Chinese platforms such as Baidu Tieba and Zhihu, so visibility strategies often extend beyond your own website.
Finally, content on Baidu must comply with Chinese government regulations on what can be published. This is a meaningful difference from Google and requires care to avoid material that would be filtered or removed.
What to ask an SEO company
Treat Baidu as a specialist request. When you talk to an agency, ask whether they have done Baidu projects before and what those projects involved. Ask how they would handle the ICP filing, whether they have a local partner in China, and how they would manage in-China or nearby hosting. Ask who would write and review the simplified Chinese content, since a native-level writer or editor is important here. Ask how they work with Baidu’s own webmaster tools and how they keep content within Chinese compliance rules.
A general SEO company may take on this work in one of three ways. Some have built genuine in-house China-market capability. Some partner with a specialist agency or local team and coordinate the project for you. Others do not offer it at all and will tell you so. Any of the first two can work, but only if the people doing the actual Baidu work have real experience with the market.
The practical takeaway
Baidu optimization is achievable and worth considering if mainland China is a target market for your business. It is not, however, a routine add-on to a standard SEO engagement. Confirm that the company either has direct Baidu experience or a clear, named arrangement with China-market specialists. If an agency promises Baidu results but cannot explain ICP filing, China hosting, or simplified Chinese content, treat that as a sign they are not equipped for the work.
