Keep the rules. Vary the expression.
Using the same template for every post is one way to create consistency, but it can also flatten the work. A more useful system defines relationships: how type behaves, how photographs are framed, how language sounds, and which ideas the brand returns to. Those rules leave room for different compositions.
Build a vocabulary, not a single sentence.
Create a small library of formats for different jobs. A product detail, a customer question, an announcement, and a point of view should not have to squeeze into the same layout. They can still share a palette, a typographic hierarchy, and an editorial voice.
Test the system with real content.
Before approving a visual direction, try it on a long headline, an ordinary phone photograph, a quiet announcement, and a major campaign. If it only works with the perfect image and three words, it is a presentation rather than a working system.
Recognition is the point
Ask whether a viewer can recognize the brand without seeing the logo. Then ask whether the content still gives them a reason to look. A good system should help you answer yes to both.
