FAQ
Is Surfer SEO better than SEMrush?
For content optimization specifically, yes. For comprehensive SEO including backlinks and site audits, no. They serve different parts of an SEO workflow.
Can I use just Surfer without SEMrush or Ahrefs?
Yes for content-only workflows. You’ll lose backlink data and site audit, which matters less for new affiliate sites focused on publishing. Add Ahrefs Lite ($129/mo) when you start optimizing existing rankings.
Does SEMrush include content optimization?
Yes — SEMrush has a Content Optimizer module. It’s solid but Surfer’s scoring is more accurate to actual SERP outcomes in our tests.
What’s the cheapest combination?
Surfer SEO Essential ($89/mo) + Ahrefs Free Webmaster Tools (free for your own site only) covers the basics at $89/mo total. See our Surfer vs Frase for budget alternatives.
What about Ahrefs vs SEMrush?
Closer fight. Ahrefs has the better backlink index; SEMrush wins on keyword tools and PPC. See our full Ahrefs vs Semrush comparison.
