The challenge

SEMrush needed to publish video content daily across social channels — from short educational clips to campaign announcements. But the production cycle was overloaded with manual tasks, from trend analysis and scripting to editing and analytics.
01
Time-consuming manual workflows with multiple creative roles
02
High production costs for short-form content
03
Limited ability to react quickly to trending topics

The solution —
