Social Copywriting & Formatting FAQs
How do line breaks affect LinkedIn reach?
Short, digestible paragraphs with clean line spacing improve read-through rates and dwell time, which is heavily favored by the LinkedIn feed algorithm.
How many hashtags should I include?
LinkedIn recommends 3 to 5 targeted hashtags. Instagram currently prioritizes search keywords over excessive hashtags (3 to 5 relevant tags perform best).
What is the best format for post images?
PNG provides crisp text rendering for graphics and screenshots. JPEG is best for photographs to keep file sizes light.
How are the mockup graphics generated?
The preview card renders directly inside your browser canvas and exports as a high-resolution 2x Retina PNG file ready for client decks.
