SEOTesting vs SISTRIX

The short answer
Editorial assessmentSISTRIX compared with SEOTesting
SISTRIX establishes that visibility changed and when; SEOTesting establishes whether your specific change caused it, using controlled tests on your own Search Console data at a fraction of the price. They answer adjacent halves of the same question. Teams shipping regular optimizations should add SEOTesting rather than inferring causation from a visibility curve.
Choose SEOTesting if
SEO practitioners, consultants, and in-house teams who already produce content and now need evidence, particularly anyone who has to defend an SEO program to a CFO or a client and is tired of pointing at a line chart and asserting causation.
Choose SISTRIX if
SEO agencies, consultants, and in-house teams working in European markets, particularly Germany, Spain, and Italy, who need defensible long-run visibility data, forensic onpage crawling, and serious AI answer tracking, and who can justify 119 to 419 euros per month.

| Best for | SEO practitioners, consultants, and in-house teams who already produce content and now need evidence, particularly anyone who has to defend an SEO program to a CFO or a client and is tired of pointing at a line chart and asserting causation. | SEO agencies, consultants, and in-house teams working in European markets, particularly Germany, Spain, and Italy, who need defensible long-run visibility data, forensic onpage crawling, and serious AI answer tracking, and who can justify 119 to 419 euros per month. |
| Setup time | Under thirty minutes to connect Google Search Console and see reports. Meaningful testing takes longer to start because someone has to design a valid experiment, define page groups, and agree not to change anything else during the window. | Visibility lookups work immediately with no setup at all, which is unusual and is the fastest way to demonstrate value on day one. Onpage projects take about half an hour each to configure, and a large crawl runs for hours afterwards. |
| Learning curve | Low for the reports, moderate for the testing. The interface is straightforward, but interpreting a test result correctly requires understanding what a control group does and does not prove, and that is a skill, not a setting. | Moderate to steep. The interface is dense, the module structure assumes you know which tool you want, and the Visibility Index needs explaining before anyone trusts it. The 2026 navigation redesign with a single tool dropdown and star-bookmarked favourites addresses this directly. |

Strengths and limitations
SEOTesting
Strengths
- The only tool in this comparison set that establishes causation rather than correlation, through both time-based forecasting and genuine split tests.
- Archives Google Search Console data past the sixteen-month retention limit, which is quietly one of the most valuable things any GSC tool can do.
- Unlimited users on every plan with pricing based solely on site count, so team size never affects the bill.
- The AI features are grounded in observable data (chatbot-referred clicks, prompt patterns, session tests) rather than in scraped model output presented as certainty.
Limitations
- Useless below a traffic threshold; testing requires enough impressions and clicks for a difference to be statistically distinguishable, and the site never tells you what that floor is.
- Not a content tool at all: no editor, no scoring, no keyword database, no backlink data, so it is always an addition to a stack rather than a consolidation of one.
- Rigor demands discipline. The tool cannot stop a team from shipping six changes at once and then reading the result as if it proved something.
- AI coverage measures referred traffic and prompts, not brand mentions or share of voice inside AI answers, so it does not replace a dedicated AI visibility tracker.
SISTRIX
Strengths
- The Visibility Index is the longest methodologically stable public SEO dataset in existence, with up to 13 years of weekly history across more than 40 countries.
- Unmatched depth in continental European markets, particularly German, Spanish, and Italian, where US-centric tools are noticeably thinner.
- The AI and Chatbots module is a real product: four AI surfaces, daily prompt monitoring, sentiment analysis, and an AI-specific visibility index with history.
- Keeping AI visibility separate from the classic Visibility Index rather than blending them is the methodologically correct choice, and a rare instance of a vendor resisting a simpler but misleading number.
Limitations
- The 119 euro entry price with only three months of data history withholds the single feature SISTRIX is famous for, which makes START poor value.
- Expensive relative to the small-business market; the useful plans start at 239 euros and the full archive costs 419 euros per month.
- Coverage and community are concentrated in Europe, so US-only teams get less differentiated value than the price implies.
- The Visibility Index is a comparable score rather than a traffic estimate, which is correct but requires explaining to every stakeholder who wants a revenue number.
Pricing compared
SEOTesting
Flat monthly tiers priced purely on the number of websites, with unlimited users on every plan and month-to-month billing.
- Single Site$50
- Medium$125
- Large$375
- EnterpriseCustom
At $50 per month for one site, SEOTesting is priced like a niche utility, and per site at the Large tier it drops under $19, which is close to trivial for an agency. The value question is not the price but the fit: it is worth every dollar to a team with enough traffic to run a real test and disciplined enough to change one thing at a time, and worth nothing at all to a site with 300 monthly clicks or a team that ships ten changes in a sprint. The Search Console data archive alone, past Google's sixteen-month window, justifies the entry price for many working SEOs before the testing features are even considered.
SISTRIX
Tiered subscription in euros with month-to-month cancellation, metered on projects, crawled URLs, SERP updates, content projects, and reporting objects, with cheap per-unit add-ons and inexpensive extra seats.
- START119 EUR
- PLUS239 EUR
- PROFESSIONAL419 EUR
- PREMIUM799 EUR
SISTRIX is expensive and mostly worth it for the specific buyer it is built for. What you are actually purchasing is thirteen years of methodologically stable visibility history across more than 40 countries, plus a crawler that is genuinely forensic at the higher tiers and an AI visibility module that treats the problem seriously rather than bundling twenty prompts as a marketing checkbox. Set against Ahrefs Advanced at $449 plus $80 per seat plus $199 to $699 for Brand Radar, PROFESSIONAL at 419 euros with the API included and users at 24.90 euros is not obviously bad value. The problem is the entry point: START at 119 euros with three months of history sells you the interface without the asset, and if you do not work in European markets you are paying a premium for depth you will never use. Price PLUS or PROFESSIONAL, or do not buy SISTRIX at all.
Editorial verdict on each
SEOTesting
SEOTesting is the most intellectually honest product in this category and the one most likely to change how a team works rather than just what it produces. Everything else here helps you make content; this tells you whether the content did anything. Split testing on a live site, a Search Console archive that outlives Google's own retention, unlimited users at $50 per month, and AI features that measure observable traffic instead of inventing a share-of-voice metric all point at a team more interested in being right than in being impressive. The constraints are equally clear: you need real traffic, real discipline about changing one thing at a time, and another tool to actually produce the content. Add it to the stack. Do not expect it to be the stack.
Read the full SEOTesting profileSISTRIX
SISTRIX is a specialist instrument sold at a specialist price, and it is excellent if you are the specialist. Nothing else offers thirteen years of methodologically stable weekly visibility data across more than 40 countries, and in European markets that archive is the evidence practitioners actually argue from. The 2026 product is also stronger than its reputation suggests: a genuinely forensic crawler with canonical-to-404 detection and live crawl logs, an AI module doing daily prompt monitoring with sentiment across four surfaces, an API included from PROFESSIONAL rather than sold separately, and month-to-month cancellation throughout. Two warnings. START at 119 euros gives you three months of history, which withholds the very thing you came for. And if your market is the United States, you are paying a European premium for depth you will not use. Buy PLUS or PROFESSIONAL, in Europe, or buy something else.
