Frequently asked questions
Surfer SEO or Frase?
Surfer for in-house teams who write content; Frase for agencies that brief external writers. Surfer's content editor is tighter; Frase's brief-builder is better for handing off work.
Is AdCreative.ai good enough for paid social client work?
Yes for fast iteration cycles and creative variations. For brand-sensitive clients (luxury, regulated industries) you'll still want a designer reviewing outputs before launch.
