Tools are the start. We do the work.
Most 3rd-party tools need a Chinese account, often a local phone number or an ads account — and all of them need someone who reads the results in Chinese. Our team in Guangzhou and Tianjin works in them every day to run Baidu SEO, Chinese GEO, Baidu Ads and paid social campaigns for Western companies.
Free tools built by Jademond Digital, a Chinese digital marketing agency founded in Guangzhou in 2012. 3rd-party tools are listed because our team uses them; we are not affiliated with their providers. About us →
