The short version

  • Only Rank Math has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rank Math all paid tiers are annual-only with no monthly option, so evaluating Pro or Business month to month before committing is not possible.; 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.
  • They diverge on capability: Rank Math covers Free schema generator, SISTRIX covers Visibility Index.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Rank Math

  • A WordPress site owner who wants more schema types and keyword optimisation than Yoast's free tier provides, at no costnot SISTRIX
  • An agency managing dozens of client WordPress sites that wants a per-site-count licence rather than per-site billingnot SISTRIX
  • A team that wants rank tracking built into the WordPress dashboard rather than as a separate subscriptionnot SISTRIX
  • A site migrating away from a paid competitor and wanting a free tier competitive enough to not need Pro immediatelynot SISTRIX

SISTRIX

  • Reporting search visibility to a board in Germany where the Visibility Index is the expected metricnot Rank Math
  • Comparing a domain against competitors over years, including before you started tracking anythingnot Rank Math
  • Due diligence on an acquisition target where you need visibility history you did not collect yourselfnot Rank Math
  • Diagnosing whether a traffic drop coincided with a core update by comparing against the whole measured marketnot Rank Math

Where each one falls short

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

Rank Math

  • All paid tiers are annual-only with no monthly option, so evaluating Pro or Business month to month before committing is not possible.
  • The advertised price is a first-year introductory rate; renewal pricing is roughly 10 to 18 percent higher across every tier, which is easy to miss when comparing sticker prices to Yoast.
  • Switching an established WordPress site to or from Rank Math risks losing accumulated redirect rules and schema configuration if the migration is not done carefully, which discourages later switching regardless of price changes.
  • It is WordPress-only, so any team running a non-WordPress CMS gets nothing from this product at all.
  • The generous free tier depends on upselling Pro and Content AI trials inside the plugin dashboard, which some users find intrusive compared to Yoast's comparatively quieter free experience.

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.

Answered from the vendors’ own pages

Rank Math: Is Rank Math really free?

Yes, for unlimited personal websites, with 18 schema types and unlimited keyword optimisation at no cost; client sites and rank tracking require a paid tier.

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.

Rank Math: Can I pay monthly instead of annually?

No. All paid plans are billed annually only; there is no monthly billing option.

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.

Rank Math: Does the advertised price stay the same at renewal?

No. Every paid tier renews at a higher rate than the first-year introductory price, by roughly 10 to 18 percent depending on the plan.

SISTRIX: How far back does the data go?

To 2008 for the earliest supported countries, which is longer than any rank tracker can offer on your own keyword list.
