Buffer's analysis of over 1 million TikTok posts reveals concrete strategies for 2026 success: the algorithm operates via "micro-testing," prioritizing watch-through time above all other metrics. Five actionable tactics for SMEs/marketers are: (1) TikTok SEO via keyword strategy, (2) leveraging native ecosystem tools (CapCut, Duets, trending sounds), (3) consistent posting (6–10+ times/week yields 29–34% view lift), (4) clear niche positioning, and (5) authentic, humanized content over polished ads. Success requires balancing data-driven optimization with genuine storytelling.
