The panel's verdict

Landingi's A/B testing runs inside its landing page builder: client-side A/B/x, multivariate and split tests in a visual editor, manual traffic splits, variants sharing one URL, a manually chosen winner. Its strongest showing is data and integrations, the only criterion scoring 4 at minimum and maximum: Google Tag Manager in-app, Google Analytics 4, Matomo, Piwik PRO and Heap, per-variant events in GA4, and one-click lead export. Weakest are performance impact at 0-1, where judges found no public information on script size, flicker handling or Core Web Vitals, and statistical rigour at 1-2, where winners are picked manually and the only guidance is several hundred conversions per variant. Judges split on experimentation scope, scores 2-4: the e-commerce manager scored 2, citing targeting as traffic percentages only, while scores of 4 credit the documented test types and editor. Sovereignty spans 0-2: data residency, subprocessor exposure and the contracting entity's jurisdiction are unconfirmed. Pricing transparency scores 2-3: a Free plan including A/B testing and a free trial are published, with no public information on paid tier prices.

Speaks for it

  • Broad documented integration catalogue — Google Tag Manager in-app plus Google Analytics 4, Matomo, Piwik PRO, Heap and Mixpanel — scoring 4 at both minimum and maximum
  • A/B/x, multivariate and split tests buildable in a visual drag-and-drop editor with mid-test editing and one-click publishing of the winner
  • A/B test events distinguishable by variant in Google Analytics 4, so results can be cross-checked in the buyer's own analytics
  • Leads from all landing pages and pop-ups centrally managed and exportable in one click
  • A published Free plan includes the A/B testing option, with a free trial also offered

Report an error

Held against it

  • Performance impact scored 0-1, with judges finding no public information on script size, flicker handling or Core Web Vitals
  • Statistical rigour scored 1-2: no statistical method is named, winners are chosen manually, and the only guidance is several hundred conversions per variant
  • Sovereignty scored 0-2, with data residency, ownership, subprocessor exposure and the contracting entity's jurisdiction unconfirmed
  • Consent and tracking scored 2-3: Cookiebot wiring via Google Tag Manager is documented, but we found no public information on what the platform's own EventTracker stores or does before consent is given
  • Pricing transparency scored 2-3, with we found no public information on paid tier prices, the traffic metric, limits or overage treatment

Report an error

Best for

  • You build landing pages in a visual drag-and-drop editor and want no-code A/B/x, multivariate and split testing with manual traffic splits
  • You already run Google Analytics 4 or Google Tag Manager and want A/B test events distinguishable by variant in your own analytics
  • You collect leads on landing pages and pop-ups and want them centrally managed and exportable in one click
  • You want to try the capability before committing spend — a free trial and a Free plan including the A/B testing option are published

Report an error

Avoid if

  • You must defend a winning variant to finance with statistical evidence — the winner is chosen manually and no statistical method is named
  • Your data protection review must confirm data residency or subprocessors before signing — we found no public information on either, and sovereignty scores span 0-2
  • Your landing pages live or die on Core Web Vitals — performance impact scores 0-1 and we found no public information on script size, loading behaviour or flicker handling
  • You are buying testing for personalisation against a control or server-side delivery — experimentation scope scores 2-4, and the pages show targeting as traffic percentages only

The scores

Panel median The median of the judges’ scores per criterion. Each label opens its reasoning below.

Experiment types & delivery

Show reasoning
How this is scored

What can be tested and where: client-side changes through an editor, server-side and feature experiments through SDKs, multivariate and multi-page tests, and personalisation — judged on what the documentation shows rather than on the feature grid.

0 — Simple A/B split of one page element through a visual editor; no server-side option, no targeting beyond URL.

3 — Client-side A/B and split-URL tests with basic audience targeting, and no SDK or server-side delivery.

5 — Client-side and server-side experiments through documented SDKs for common languages, multivariate and multi-page tests, audience targeting on behaviour and attributes, and rule-based personalisation.

8 — Feature-flag-based experiments sharing one audience and metric model with web tests, mutually exclusive experiment groups, holdouts, edge or CDN delivery, and personalisation that can itself be tested against a control.

10 — One experimentation programme across every surface: web, app, server and edge from the same platform, experiment interactions managed, a documented experiment lifecycle from hypothesis to archived result, and a library of past results a team can search.

Report an error

The Growth Lead

Variants are built in the same visual drag-and-drop editor with no code, and A/B/x, multivariate and split tests are all documented with a manual traffic split and mid-test editing — genuinely usable by my team without a developer. But test targeting never goes beyond the traffic-split percentage, and we found no public information on server-side delivery, SDKs, audience conditions or personalisation. 2 3

Report an error

The E-Commerce Manager

A/B/x tests, multivariate tests and split testing are all documented in a visual drag-and-drop editor with variants sharing the main variant's URL and a manual traffic split, which serves landing pages fine. But the pages show targeting as traffic percentages only, and I found no public information on server-side SDKs, feature flags, or personalisation that can be tested against a control — the capability I actually buy for. 2 3

Report an error

The Product Engineer

Documented A/B/x tests, multivariate element combinations and split testing across pages, all built by duplicating variants in the visual editor with a manual traffic split and a manually chosen winner. We found no public information on server-side SDKs, feature flags, edge delivery, or audience targeting for experiments. 2 3

Report an error

The CRO Consultant

A/B, A/B/x, multivariate and same-URL split testing are documented, with variants built in the drag-and-drop editor, unlimited variants, manual traffic splits, mid-test edits and one-click publishing of the winner. We found no public information on server-side or SDK delivery, feature flags, edge or CDN delivery, behavioural audience targeting, or personalisation within the testing tool, so the scope stays in client-side editor territory. 2 3

Report an error

The Data Protection Officer

The pages document client-side A/B/x, multivariate and split testing with manual traffic splits, a visual drag-and-drop editor and variants sharing one URL, while pop-up display rules offer frequency and trigger settings. We found no public information on any SDK, server-side or edge delivery, holdouts, mutually exclusive groups, or personalisation tested against a control. That sits above a basic split-and-target product and short of a client-plus-server programme. 2 3 4

Report an error

The Skeptic

Client-side A/B, A/B/x, multivariate and split tests on the vendor's own landing pages, with variants edited live, manual traffic splits and a one-click publish of the chosen winner — all delivered on one shared URL through the visual editor. We found no public information on server-side SDKs, feature flags, holdouts, mutually exclusive experiments or personalisation audiences, which keeps this just above plain client-side testing. 2 3

Statistical method & guardrails

Show reasoning
How this is scored

Which statistics decide the winner and what protects the customer from misreading them. Scored on what the vendor documents: the method by name, how peeking and multiple comparisons are handled, and whether sample ratio mismatch is detected.

0 — A "winner" or "probability to beat" figure with no documented method, no stated sample-size guidance and no warning against stopping early.

3 — The method is named (frequentist or Bayesian) but its assumptions are not documented, and nothing prevents a test from being called while it is still underpowered.

5 — Documented method with confidence or credible intervals, a sample-size or test-duration calculator, and stated guidance on when a result may be read.

8 — Sequential testing or an equivalent documented protection against peeking, correction for multiple metrics or variants, sample ratio mismatch detection, variance reduction such as CUPED, and guardrail metrics that can stop a harmful test.

10 — The statistics are auditable: methodology published in enough detail to reproduce a result, the choice of method explained per use case, raw per-visitor data available for independent re-analysis, and the interface refuses to present an underpowered result as a conclusion.

Report an error

The Growth Lead

The dashboard reports traffic split, visits, leads and conversion rate per variant and the winner is chosen manually, with a recommendation to accumulate several hundred conversions per variant as the only guidance on duration. We found no public information on a named statistical method, confidence intervals, sample ratio checks or anything preventing a call while a test is underpowered — that is not a number I could defend to finance. 2 3

Report an error

The E-Commerce Manager

The dashboard reports traffic split, visits, leads and conversion rate in real time, the winner is chosen manually, and the only guidance is a recommendation of several hundred conversions per variant, which lifts it just above nothing. I found no public information naming the statistical method, on confidence or credible intervals, on protection against early stops, or on sample ratio checks. 2 3

Report an error

The Product Engineer

The documentation shows raw counts — traffic split, visits, leads, conversion rate — and recommends heavy traffic with several hundred conversions per variant, then leaves the winner to a manual pick. No statistical method is named, and we found no public information on intervals, a sample-size calculator, or protections against peeking and sample ratio mismatch. 2

Report an error

The CRO Consultant

The results dashboard shows visits, leads and conversion rate per variant in real time, and the winner is chosen manually by the user. The only documented guidance is a recommendation to run tests on heavy traffic with several hundred conversions per variant; we found no public information naming a statistical method, showing confidence or credible intervals, protecting against reading a test early, or detecting a sample ratio mismatch. 2 3

Report an error

The Data Protection Officer

Tracked metrics are traffic split, visits, leads and conversion rate, the winner is chosen manually, and the only guidance is a recommendation to accumulate several hundred conversions per variant. We found no public information naming a statistical method, stating confidence or credible intervals, guarding against stopping a test early, or detecting a sample ratio mismatch. 2 3

Report an error

The Skeptic

No method is ever named — no significance test, no interval, no sample-size calculator — and the customer manually picks the winner from a real-time conversion-rate dashboard whenever they please, which is peeking by design. The only guardrail I found is a verbal recommendation to accumulate several hundred conversions per variant; we found no public information on multiple-comparison handling or sample-ratio-mismatch checks, so the several-variant tests they invite are unprotected on every axis I read for. 2 3

Snippet performance & flicker

Show reasoning
How this is scored

The cost the client-side snippet imposes on the page it tests: blocking load, flicker of original content, script weight and the effect on Core Web Vitals — scored on what the vendor measures and publishes, not on "lightning fast".

0 — A synchronous snippet with no stated size, no flicker handling and no mention of performance.

3 — An anti-flicker snippet that hides the page until the test loads, with a timeout, and no published figures for script size or load cost.

5 — Script size and loading behaviour documented, asynchronous loading option, flicker handling explained with its trade-off, and CDN delivery of the snippet.

8 — Published performance figures including impact on Core Web Vitals, a self-hosting or first-party-domain option for the script, per-project bundles containing only active experiments, and a server-side or edge alternative for flicker-sensitive tests.

10 — Performance is a stated commitment: measured overhead published and maintained, flicker eliminated by edge or server-side rendering as a documented path, and tooling that shows the customer what their own configuration costs the page.

Report an error

The Growth Lead

We found no public information on script size, loading behaviour, flicker handling or Core Web Vitals impact in any of the captured testing or help pages. For a test whose variants share the main variant's URL, that is the first question my dev team would ask, and the captured pages leave it unanswered. 2 3

Report an error

The E-Commerce Manager

Since every variant shares the main variant's URL, how the original content is held while a variant loads is the first thing I need documented, and I found no public information on script size, loading behaviour, flicker handling, or any effect on Core Web Vitals anywhere on the captured pages. Nothing is measured or published on the cost the test imposes on the page. 2

Report an error

The Product Engineer

The testing documentation covers variant creation, traffic splits and winner publication, but we found no public information on script size, loading behaviour, flicker handling, CDN delivery or Core Web Vitals impact. 2 3

Report an error

The CRO Consultant

We found no public information on script size, loading behaviour, flicker handling or any Core Web Vitals impact — the A/B testing documentation describes the tests and dashboards without a single published performance figure. 2 3

Report an error

The Data Protection Officer

The only delivery mode evidenced is client-side variants published on a shared URL, and we found no public information on script size, loading behaviour, anti-flicker handling, any effect on Core Web Vitals, or a self-hosting or edge alternative. 2 3

Report an error

The Skeptic

I found no public information on script size, loading behaviour, flicker handling or Core Web Vitals — not a figure and not a sentence. Variants are served on the same URL, so delivery is client-side, and nothing published addresses the cost that imposes on the page. 2

Analytics, data export & integrations

Show reasoning
How this is scored

Getting results and raw data out: integration with analytics and tag management, export of visitor-level results, warehouse-native analysis, and an API — because an experiment result that cannot be checked in the customer's own data is a claim, not a finding.

0 — Results visible in the vendor's dashboard only; no export, no analytics integration, no API.

3 — CSV export of aggregated results and one analytics integration, with no visitor-level data and no documented API.

5 — Integrations with common analytics and tag managers, export of results, and a documented API for managing experiments and reading results.

8 — Visitor-level raw data export or streaming to a data warehouse, warehouse-native analysis on the customer's own metrics, CDP integration for audiences, and an API with stated limits.

10 — The platform treats the customer's warehouse as the source of truth: metrics defined once and computed there, full historical experiment data exportable in open formats, and a versioned API a team can build its own programme tooling on.

Report an error

The Growth Lead

The integrations catalogue is broad — Google Analytics 4 and Google Tag Manager in-app, Matomo, Piwik PRO and a dozen more — and A/B test events can be distinguished by variant in Google Analytics 4, with collected leads exportable from one central view. We found no public information on a documented API or on export of visitor-level experiment data, so any deep re-analysis has to happen in my analytics stack rather than from the tool. 4 7 8 2

The analytics story is broad: Google Analytics 4 and Google Tag Manager in-app, Meta Pixel, Matomo, Piwik PRO, Heap, Mixpanel and a long catalogue besides, plus documented per-variant event tracking through GA4 and a one-click export of form leads from the central leads tab. We found no documented API for reading or managing experiments and no visitor-level or warehouse export of test data, so a result can only be checked inside whatever analytics the client wires up, not from the platform itself. 2 4 7

The Skeptic

A genuinely broad analytics catalogue — Google Analytics 4 and Tag Manager in-app, plus Matomo, Piwik PRO, Mixpanel, Heap and more — with lead-level export and A/B events distinguishable in the customer's own analytics, so results can be cross-checked outside the dashboard. We found no public information on a documented API, visitor-level raw export or warehouse delivery, which caps it below the level where an experiment is fully auditable in the customer's own data. 2 4 7

European sovereignty panel opinion

Show reasoning
How this is scored

Where visitor data is processed and stored and who the contracting entity is. Independently sourced by the sovereignty pipeline; weighted higher here than in categories that hold only the customer's own data, because the script runs on every visitor to the customer's site and their behaviour is what the platform records.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and visitor data leaving the EU without a stated safeguard.

3 — EU data residency offered as an option or an enterprise add-on while the contracting entity is non-EU, or the subprocessor list is absent.

5 — EU processing of visitor data as standard and an EU contracting entity, but parts of the chain — CDN, support access, analytics — are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure including the delivery of the snippet, EU contracting entity, subprocessor list published, and a DPA covering the visitor data the script collects.

10 — Sovereign end to end and evidenced: vendor, entity, hosting, snippet delivery and every subprocessor European, certification published, and no visitor data reaching a non-EU party at any point.

Report an error

The Growth Lead

We found no public information confirming where visitor data is processed or hosted, no subprocessor list, and the contracting entity's jurisdiction is not confirmed on the captured pages. For a script that records every visitor's behaviour on our pages, that is not something I can take to our data protection officer as it stands. 1 6

Report an error

The E-Commerce Manager

The company name points to a Polish limited-liability form, but the captured pages confirm nothing about where visitor data is processed or hosted, and I found no public information on a subprocessor list, on the delivery chain for the tracking script, or on a data processing agreement covering the visitor data it records. For a script that runs on every visitor, that is a blank page. 6

Report an error

The Product Engineer

We found no public information confirming where visitor data is hosted, the contracting entity's jurisdiction on the vendor's own captured pages, or any subprocessor list. The captured GDPR page yields no residency or safeguard statements either. 1 6

Report an error

The CRO Consultant

The captured pages state nothing about where visitor data is processed or stored, and even the contracting entity's jurisdiction is marked as not confirmed on the vendor's own pages — the Polish corporate form in the company name is the only European signal we found. With hosting, snippet delivery and the subprocessor chain equally undocumented, I could not defend this to a client DPO for a script that records every visitor's behaviour. 1 6

Report an error

The Data Protection Officer

The contracting entity is named, but its jurisdiction is not confirmed on the captured pages, and we found no public information on where the centrally managed leads and built-in event data are hosted, on data residency, or on a published subprocessor list including the delivery network. Without these, EU processing of visitor data cannot be verified from the vendor's own pages. 4 6

Report an error

The Skeptic

Every sovereignty attribute came back unconfirmed: contracting entity jurisdiction, ownership, data residency and subprocessors are all marked unknown, and the captured GDPR page yields no hosting or processing statement. I found no public information that visitor data stays in the EU at any point, so I score the absence. 1 6

Pricing transparency

Show reasoning
How this is scored

A category priced by traffic — monthly tracked users, visitors or impressions — where the tier a site lands in depends on numbers the buyer has to estimate. Whether a buyer can compute the real annual cost including traffic limits, overage, server-side or personalisation modules and seats — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A starting price or a free tier exists, but the traffic metric, the limits and what happens above them are unstated — the invoice is unknowable.

5 — Tier prices public with the traffic metric and its limits defined, but at least one commonly needed piece (server-side SDKs, personalisation, overage) is unpriced or "contact sales".

8 — Every tier priced publicly with the traffic metric defined, limits, overage rates, module prices, minimum term and VAT treatment stated.

10 — Complete price computability: annual invoice derivable for a given traffic volume, set of modules and team size, with overage and every add-on published.

Report an error

The Growth Lead
