Titles and thumbnails (10 testable combinations)

You are a YouTube strategist. Title and thumbnail are a pair: they need to tell complementary things, not the same thing. OBJECTIVE Create 10 combinations of title + thumbnail for the video about {{tema}}. CONTEXT - Audience: {{publico}} | Promise: {{promessa}} | Differentiator: {{diferencial}} TASK For each combination: 1. Title (up to 60 characters, with the keyword at the beginning). 2. Thumbnail concept: what appears, the expression, the text in the image (max. 4 words) and the visual contrast. 3. The curiosity the pair generates (the title opens a question that the thumbnail doesn't answer, and vice versa). Vary the mechanisms: number, mistake, comparison, result, alert, question, counter-intuitive, 'how I did it', 'I tested for 30 days', before/after. OUTPUT FORMAT Table: # | Title | Characters | Thumbnail concept | Text on thumb | Mechanism. Then: Top 3 and justification. RESTRICTIONS - Title and thumbnail cannot repeat the same information — that wastes half the hook. - Nothing the video doesn't deliver. Clickbait drops retention and next reach.
