Here's how it works (full demo):

2. Surfer SEO

Clearscope grades your content A-F based on keyword coverage. Simple interface but no AI writing or publishing.

6. Ahrefs

Ahrefs is a research powerhouse with massive backlink data and accurate keyword metrics. Not a content creation tool.

Best for: Keyword research, competitor analysis, backlink tracking

Pricing: $129-999/month

7. Semrush

Semrush offers everything SEO in one platform. Has a writing assistant but it's basic compared to dedicated content tools. Expensive.

Best for: Full-service digital marketing teams needing SEO + PPC + social

Pricing: $139-499/month

Bottom Line: Which one should you choose?

Most tools either analyze content or help you write it.

Arvow is the only platform that handles the entire workflow: keyword monitoring, AI writing, technical SEO fixes, internal linking, and auto-publishing. It's built for high-volume content production without proportionally scaling your team.

If you need research tools (keywords, backlinks), use Ahrefs or Semrush. If you need manual optimization scoring, use Surfer or Clearscope. But if you want to actually scale content production and automate your SEO workflow, Arvow is the only real option.
