Algorithm Countermeasures
Xiaohongshu’s R&D department independently develops content distribution algorithms and advertising algorithms, and has an anti-cheat audit team. UnderWater, on the other hand, operates its own independent algorithm research center dedicated to monitoring and studying Xiaohongshu’s overall algorithm system. This enables UnderWater to deliver multi-dimensional marketing and promotion service value, including stealth marketing, keyword occupying/positioning, account registration/cultivation/nurturing, and matrix building.
Purpose of Grass-planting
UnderWater invests significant human, material, and financial resources into its Xiaohongshu promotion marketing services, with the primary goal of helping brand clients acquire more search traffic. Search traffic holds greater value, has higher conversion potential, and contains more potential leads. Simultaneously, brand clients can accumulate a wealth of high-quality content on the Xiaohongshu platform, which serves as foundational material for brand reputation dissemination.
Industry Experience
In China, several major industries face strict restrictions, such as financial investment, real estate, healthcare, and education. When publishing related content on Xiaohongshu, any misstep can prompt immediate system warnings requiring proof of industry qualifications. The content may then become unviewable, and accounts might face posting bans or interaction restrictions. UnderWater has been deeply engaged in Xiaohongshu grass-planting promotion marketing for 8 years. We respond promptly to every policy adjustment made by Xiaohongshu. Through eight years of frontline practical experience, UnderWater has developed systematic, end-to-end execution capabilities encompassing content topic selection, content creation, note ranking optimization, interactive atmosphere building and shaping, and data analysis and review. We are committed to providing brand clients with safer and more effective Xiaohongshu grass-planting marketing solutions.
Internal Capabilities & Cultivation
UnderWater places extreme importance on content creation, insisting on manually written note copy. Our copywriters, operations specialists, and designers collaborate efficiently to originally produce note cover images and supporting graphics, strictly avoiding reliance on AI tools. The Xiaohongshu platform utilizes advanced NLP semantic analysis technology, AI large model algorithm recognition technology, and Body Segment image recognition and deduplication technology. Content directly generated by AI is not granted promotional traffic support or note link weighting, as Xiaohongshu encourages users to record and share authentic, native content rather than AI-generated non-authentic material. UnderWater focuses on honing internal skills, steadfastly creating original, native content, and consistently upholding our service commitments to brand clients.
