Most web copy fails because it is written from the inside out: what the company does, rather than what the client gets. Here is our framework.
The three layers
Layer 1 — Outcome. Lead with what the client achieves, not what you do. "Get a website that turns visitors into clients" beats "We build custom websites".
Layer 2 — Evidence. Specificity earns trust. "11 years in business" is weaker than "We have migrated 47 Drupal 7 sites to Drupal 11 without a single client losing search rankings." The second claim is verifiable and meaningful.
Layer 3 — Objection removal. Every visitor has objections. Identify the top three and address them before they are asked. For agency services, the common objections are: it will be too expensive, it will take too long, and I will have to manage the project myself. Address all three.
