Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SISTRIX

  • Coverage is deepest in German-speaking Europe and thinner in the United States and Asia, so international teams still need Ahrefs or Semrush alongside it.
  • The Visibility Index is domain-level, so a dramatic chart movement can come entirely from pages that carry no commercial value and requires drilling down before it means anything.
  • The link index is smaller than the market leaders, which matters if backlink discovery rather than visibility measurement is your main use.
  • Modules are priced individually, so a team that needs SEO, links and the Optimizer pays a multiple of the entry price for one module.
  • Documentation, community material and support are German-first, and while English is available the depth of the two is not equal.

Surfer SEO

  • Entry Discovery plan at $49 per month limits users to a single seat and 120 documents
  • AI prompt tracking is excluded on the Discovery plan and capped at 25 prompts weekly on Standard, 50 daily on Pro
  • Unlimited documents on the Peace of Mind plan are subject to a fair usage policy rather than being truly unlimited

Answered from the vendors’ own pages

SISTRIX: What is the Visibility Index actually measuring?

Rankings for a large fixed keyword set per country, weighted by expected traffic, measured weekly. It is not your keyword list, which is what makes it comparable.

Surfer SEO: How much does Surfer SEO cost?

Surfer SEO offers four tiers: Discovery at $49 per month, Standard at $99 per month, Pro at $182 per month, and Peace of Mind at $299 per month. All pricing is in USD. Annual billing provides substantial savings.

SISTRIX: Can it replace Ahrefs or Semrush?

For German-language visibility reporting and competitor history, yes. For global keyword research and backlink analysis it is a complement rather than a replacement.

Surfer SEO: What is the difference between Surfer's AI SEO plans?

Discovery includes 120 documents and basic tracking. Standard adds 360 documents and weekly AI prompt tracking. Pro adds daily prompt tracking and multiple brand workspaces. Peace of Mind includes unlimited documents, daily prompt tracking, and a dedicated success manager.

SISTRIX: How far back does the data go?
