AI CONTENT IS EVERYWHERE ON SOCIAL MEDIA, ESPECIALLY LINKEDIN

Summary from the TLDR Marketing newsletter

AI-generated content is spreading across social media, with longform posts hit the hardest. Pangram data from over 1M posts shows 13.8% flagged as AI, rising to 25% for posts over 250 words. LinkedIn drives nearly two-thirds of flagged content, with over 40% of longform posts fully AI-generated. X shows the highest combined AI use when including mixed content. Reddit replies remain mostly human, but top-level posts show higher AI rates, revealing gaps in moderation.
