Strategy, content, creator partnerships, scheduling, and platform-specific tactics for Facebook, Instagram, LinkedIn, TikTok, X, Pinterest, and YouTube. The articles here are about doing fewer things better — picking the right platform for the audience, building a publishing rhythm you can sustain, and measuring engagement honestly. New marketers should start with the social media channels guide and the seasonal-campaign planning article. Brands moving into creator partnerships will get more from the influencer pieces in the linked sub-category. SEMUpdates avoids growth-hacking advice that depends on platform exploits or vanity metrics, and never recommends fake-follower services. Expect updates whenever the major platforms change their algorithms, ad formats, or creator rules.
