Read this page as one judge. Each weighs the same scores by what they care about.

The E-Commerce Manager

Weighted verdict

Owns a shop where a tenth of a second of load time shows up in the conversion rate. Wants personalisation that can be tested against a control, a snippet that does not flicker the product page, and a traffic-based price that does not jump a tier every December.

Same scores as the panel view — this lens weights them the way this judge cares.

Experiment types & delivery

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 — Not an experimentation tool; the product cannot split traffic or serve variants (analytics, heatmaps or session recording only).

3 — Client-side A/B tests built in a visual editor, with a traffic split and targeting by URL or device.

5 — A/B, split-URL and multivariate tests through a visual or code editor, audience targeting on behaviour and attributes, and either rule-based personalisation or server-side experiments through a documented SDK.

8 — Client-side and server-side experiments through documented SDKs for common languages, multi-page tests, feature-flag experiments sharing one audience and metric model with web tests, mutually exclusive experiment groups, holdouts, 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 E-Commerce Manager

A/B tests with up to four variants, custom traffic splits, three testing modes, and rule-based personalisation on ad source, device, location, time of day and CRM stage are all documented, with the variant assigned server-side before render. I found no evidence of multivariate tests, a server-side SDK for my own stack, holdouts, or personalisation that can itself be tested against a control — Smart Traffic shifts traffic automatically, which is optimisation, not proof. 5 6

Statistical method & guardrails

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 — No statistical evaluation; the product shows raw counts per variant and leaves the decision to the user.

3 — A results report per variant with the method named (frequentist or Bayesian) and a significance or probability-to-beat figure.

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

8 — Sequential testing or another documented protection against peeking, plus 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 E-Commerce Manager

The vendor names its method — a two-proportion z-test with Bonferroni correction, reported in three confidence bands — which is more than most landing-page tools publish. I found no sample-size or duration guidance, no intervals per variant, and nothing on peeking or sample ratio mismatch, and the continuous optimisation loop on the top plan runs unattended. 5 6

Snippet performance & flicker

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, render-blocking snippet stated as the only way to install the product, with no flicker handling.

3 — An asynchronous or anti-flicker snippet with a timeout, described in the installation documentation.

5 — Asynchronous loading and flicker handling explained with their trade-off, the snippet delivered from a CDN, and its size or loading behaviour documented.

8 — Published performance figures including the 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 E-Commerce Manager

Flicker is handled where it matters to me: the variant is decided server-side before the page renders, pages are delivered through Cloudflare, and no second snippet or tag manager is added to the page. I found no published figures for load cost or Core Web Vitals, so the no-flicker claim rests on the architecture rather than on measurement. 3 5 6

Analytics, data export & integrations

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 — A closed dashboard: the vendor states that results cannot be exported or sent to another tool.

3 — Results exportable as a CSV file or report, and an integration with at least one named analytics tool.

5 — Integrations with common analytics and tag managers (Google Analytics, Adobe Analytics, Google Tag Manager or similar), export of results, and a documented API or webhooks.

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 for managing experiments and reading results 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 E-Commerce Manager

GA4 with automatic page views plus custom and e-commerce events, a Google Tag Manager container that loads on every page, real-time webhooks, Zapier and an OAuth-secured API are all documented, and conversion data flows back to the ad platforms. I found no public information on visitor-level raw export or stated API limits, and warehouse access appears only as a feature line on the top plan. 3 9 10 11

European sovereignty

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 — Vendor, contracting entity and processing of visitor data all shown to be outside the EU, with no transfer safeguard stated.

3 — A named contracting entity and a privacy policy or data processing agreement; EU data residency offered as an option or add-on, or the hosting location not stated.

5 — EU hosting or EU processing of visitor data stated as standard, together with an EU contracting entity or a published subprocessor list, and a data processing agreement offered.

8 — EU contracting entity, EU hosting on named infrastructure including the delivery of the snippet, a subprocessor list published with locations, and a data processing agreement 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 E-Commerce Manager

The contracting entity is Leadpages (US), Inc. with a DPO address in Minneapolis, the privacy policy states personal data is processed outside the EEA and UK including in the United States, and the platform runs on AWS and Cloudflare. No EU residency option, transfer safeguard or data processing agreement appears on the captured pages, and the GDPR page says "Coming Soon". 2 3 7

Pricing transparency

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 public "from" price, a free tier or one priced tier, while the other tiers or the traffic metric behind the price are not stated.

5 — Prices public per tier with the billing period and the traffic metric (tracked users, visitors or impressions) and its limits stated; modules such as server-side SDKs or personalisation, or overage, may still be "contact sales".

8 — Every tier and module priced publicly with the traffic metric defined, limits, overage rates, seats, 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 E-Commerce Manager

Three tiers are priced publicly — Grow at $99/mo, Optimize at $199/mo and Scale at $399/mo, from a starting price of $49/mo — and traffic is unlimited with "no visitor caps and no overage fees on any plan", which is exactly the December-proof pricing I want; the metered item is Visitor Intelligence at 1,000 to 10,000 resolutions per month. I found no public information on the Business tier's price, seats, minimum term or VAT treatment, and the captured pages give different custom-domain counts for the same plans. 5 6 9
