Combining AI Writing + SEO Tools

The most effective workflow combines a general AI writer with a dedicated SEO tool:

Research: Use [Frase](/tools/frase) or Surfer to generate content briefs

Write: Draft with [ChatGPT](/tools/chatgpt), [Claude](/tools/claude), or [Writesonic](/tools/writesonic)

Optimize: Paste into Surfer's Content Editor and refine until score hits 80+

Monitor: Track rankings and detect decay with Frase's analytics

This stack costs as little as $35/month (Writesonic + Frase) and produces content that consistently ranks.

The Bottom Line

AI SEO tools have made it possible for anyone to create content that competes with established sites. Whether you choose Surfer SEO's comprehensive platform or Frase's budget-friendly approach, the key is using data to drive your content strategy rather than guessing.
