Core Principles (Brand Context -- manual change only)
Specificity Over Generality: Every claim must be grounded in a concrete detail. Replace "we help businesses grow" with a specific mechanism or outcome.
Active Voice, Present Tense: Default to active constructions. Use present tense for capabilities, past tense only for case study results.
Reader-Centric Framing: The subject of every headline should be the reader or their outcome, not the agency. "You" before "We."
Conversational Authority: Tone sits between casual blog and formal whitepaper. Confident but not stiff. Knowledgeable but not jargon-heavy.
Brevity as Respect: Every word must earn its place. If a sentence can lose a clause without losing meaning, cut it.
Evidence-Backed Claims: Quantify where possible. "3x faster" over "significantly faster." Cite sources or case studies for performance claims.
No Filler Phrases: Eliminate "In today's fast-paced world", "leveraging cutting-edge", "at the end of the day", and similar empty constructions.
