The panel's verdict

Convert Experiences is a client-side A/B testing platform from Convert Insights, Inc. The strongest scores are for data and integrations: API access, an MCP server and 90+ integrations on all plans, plus raw-data CSV export. Experimentation scope rests on a test menu — A/B, split-URL, multivariate, multi-page, full-stack with feature flags — with a sample ratio mismatch check on the entry plan. The weakest criterion is performance impact, where the only published evidence is the claim that the Akamai CDN will 'deliver your content fast'; no script size, flicker handling or Core Web Vitals figures appear. That criterion is a genuine split: one judge at 4 credited Akamai delivery and the $1000/year CNAME custom-domain option; the rest scored 1-2, finding no measurements. Pricing transparency split from 4 to 7 over whether published overuse rates ($399 per 100K on Growth, $699 per 250K on Pro, switchable off) and VAT treatment offset unpublished base prices and a price-on-request Enterprise tier. Sovereignty scored a uniform 4: visitor data documented to stay in Europe on German servers, against a Delaware contract.

Speaks for it

  • Data and integrations scored 5-6, the strongest criterion, with API access, an MCP server and 90+ integrations on all plans plus raw-data CSV export
  • The test menu is named and specific — A/B and split-URL testing, multivariate, multi-page, behavioural targeting and full-stack with feature flags — with a sample ratio mismatch check on the entry plan
  • Sovereignty scored a uniform 4, with visitor data documented to stay in Europe on German servers, Frankfurt servers on all plans and a published DPA
  • Traffic-pricing mechanics are public: overuse at $399 per 100K on Growth and $699 per 250K on Pro, switchable off, VAT by billing location, and a $1000/year per domain custom-domain add-on
  • Published tracking statements are specific — first-party-only cookies with a six-month non-PII lifetime, IP addresses not stored to work out identity, and an opt-out link customers can place

Report an error

Held against it

  • Performance impact scored 1-4, the weakest criterion, with the Akamai promise to 'deliver your content fast' the only performance evidence on the captured pages
  • Statistical rigour scored 3-4 as no captured page names the method that decides a winner, or shows intervals, sample-size guidance or multiple-comparison handling
  • Consent and tracking scored 2-4, with no public information on what the script does before consent, on consent-management platform integration, or on a consent-pending mode
  • No base tier price is published, the Enterprise tier is price on request and the terms allow additional fees for some features, so the annual invoice is not computable from public pages
  • The contract runs with Convert Insights, Inc. under Delaware law, customer account data is stored in the US under the Data Privacy Framework, and we found no published subprocessor list although the privacy notice says authorized third parties may track visitors including IP addresses

Report an error

Best for

  • You want results you can check outside the vendor's dashboard — API access, an MCP server, 90+ integrations and raw-data CSV export are on all plans
  • You pitch EU-based hosting to clients — visitor data is documented to stay in Europe on German servers, Frankfurt servers ship on all plans, and a DPA is published
  • You need governable traffic pricing — per-tier caps and switchable overuse ($399 per 100K on Growth, $699 per 250K on Pro) let you cap the cost of a traffic spike
  • You want the full test menu before paying — the 15-day free trial includes all features of the chosen paid plan, with no credit card required

Report an error

Avoid if

  • You cannot put an unmeasured script on revenue-critical pages — performance impact scored 1-4 and the captured pages show no script size, loading behaviour, flicker handling or Core Web Vitals impact
  • Your analytics sign-off must name how a winner is decided — ask the vendor: the public pages we read do not show it
  • Your DPO must know what the script does before consent is given — consent and tracking scored 2-4 and the captured pages give no public information on consent-pending behaviour or consent-management platform integration
  • You need a computable annual invoice before contacting sales — ask the vendor: the public pages we read do not show it

The scores

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

The plan pages list multivariate, multi-page, full-stack and feature-flag testing plus behavioural targeting, which is real breadth beyond URL splits. We found no public information on the SDKs behind the full-stack claim, on a visual editor my marketers could use without a developer, or on personalisation — two things my team would need on day one. 2 3

Report an error

The E-Commerce Manager

The captured pages show a genuinely broad test menu — multivariate, multi-page, split-URL redirects, behavioural targeting and full-stack feature flags on the top tier — which covers most of what I would run on a shop. We found no public information on personalisation at all, let alone personalisation tested against a control, and full-stack appears as a feature name with no documented SDKs or languages. 2 3

Report an error

The Product Engineer

The captured pricing pages list A/B and split-URL tests, multivariate and multi-page testing, behavioural targeting, and full-stack experiments with feature flags on the upper tiers — the right shape — but the evidence names no SDK languages and we found no public information on holdouts, mutually exclusive experiment groups, or personalisation, so the server-side half rests on a feature name alone. 2 3

Report an error

The CRO Consultant

The test types I build programmes on are named and specific: A/B and split-URL testing with behavioural targeting on the entry plan, and multivariate, multi-page, full stack and feature flags, bandit and sequential testing one tier up. Server-side delivery is evidenced only as a feature name though, and we found no public information on documented SDKs, personalisation, mutually exclusive experiments or holdouts, so I stop at the middle of the road. 2 3

Report an error

The Data Protection Officer

Client-side A/B and split-URL testing, multivariate and multi-page tests, behavioural targeting and a full-stack feature-flag tier are all listed on the vendor's own pages, but the SDKs behind the server-side tier are not documented in what we captured. We found no public information on mutually exclusive groups, holdouts, edge delivery of experiments, or personalisation that can itself be tested. 2 3

Report an error

The Skeptic

The feature lists show client-side A/B and split-URL testing, multivariate and multi-page testing, behavioural targeting and a full-stack feature-flag tier — a broad programme — but everything I can see is a pricing-grid bullet: no documented SDKs for common languages, no personalisation, no mutually exclusive experiment groups or holdouts, and no published experiment lifecycle or searchable results library. 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

A sample ratio mismatch check ships on the Growth plan and sequential testing with a multi-arm bandit arrive on Pro, so the guardrail vocabulary exists. We found no public information naming the statistical method, offering a sample-size or duration calculator, or stating when a result may be read — exactly what I need before defending uplift to finance. 2

Report an error

The E-Commerce Manager

A sample-ratio-mismatch check even on the entry tier, plus sequential testing and a multi-arm bandit on the top tier, are the guardrails I want before trusting a winner on my checkout. But we found no public information naming the statistical method, and no confidence intervals or sample-size calculator, so I cannot see what actually decides the winner. 2

Report an error

The Product Engineer

An SRM check ships on every paid tier and sequential testing plus a multi-arm bandit arrive on Pro, which is more guardrail than most publish — but we found no public information naming the statistical method, confidence or credible intervals, sample-size guidance, or correction for multiple comparisons, so I cannot audit a winner call. 2

Report an error

The CRO Consultant

Two genuine guardrails are published — an SRM check even on the entry plan and sequential testing one tier up — which is more than a bare winner badge. But the decision method is never named as frequentist or Bayesian anywhere I could point a client's analytics lead to, and we found no public information on intervals, a sample-size calculator, multiple-comparison handling or guidance on when a result may be read. 2

Report an error

The Data Protection Officer

A sample-ratio-mismatch check, sequential testing and a multi-arm bandit appear as plan features, which shows guardrail functionality exists as a product; the statistics that decide a winner are not named on the captured pages. We found no public information on sample-size guidance, confidence or credible intervals, or correction for multiple metrics and variants. 2

Report an error

The Skeptic

A sample ratio mismatch check ships on the entry plan and sequential testing and a multi-arm bandit are named features, so someone has read the literature — but no page names the estimation method, documents its assumptions, shows confidence or credible intervals or a sample-size calculator, or says how multiple metrics or variants are corrected. A 'Sequential Testing' bullet is a promise, not a protocol. 2

Snippet performance & flicker

panel disagrees 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

The only performance evidence on the captured pages is the claim that the Akamai CDN will deliver your content fast. We found no public information on script size, loading behaviour, flicker handling, or any measured effect on Core Web Vitals. 2

Report an error

The E-Commerce Manager

My product pages cannot afford a flicker, and this is the thinnest story in the captures: Akamai delivery that will "deliver your content fast" is the whole of it. We found no public information on script weight, asynchronous loading, anti-flicker handling, or any published Core Web Vitals figures. 2

Report an error

The Product Engineer

Snippets are delivered over the Akamai CDN and a first-party CNAME domain option is priced at $1000/year per additional domain beyond plan allowances, yet we found no public information on script size, asynchronous loading, flicker handling, or measured Core Web Vitals impact. 2

Report an error

The CRO Consultant

Performance appears as a claim, not a measurement: the Akamai CDN "will deliver your content fast" and a CNAME custom-domain option exists. We found no public information on script size, loading behaviour, anti-flicker handling or any measured Core Web Vitals impact, so I cannot estimate what a client's pages would pay. 2

Report an error

The Data Protection Officer

The only performance evidence is the vendor's statement that the Akamai content distribution network will deliver test content fast, plus Frankfurt-based servers. We found no published figures for script size or loading cost, no anti-flicker snippet described, and no measurement of the effect on Core Web Vitals. 2

Report an error

The Skeptic

The only performance evidence on the captured pages is a marketing line that the Akamai CDN 'will deliver your content fast'; I found no public information on script size, loading behaviour, flicker handling, Core Web Vitals impact, self-hosting or per-project bundles. 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

API access and an MCP server are on all plans alongside 90+ integrations, and raw data export to CSV is published. We found no public information on warehouse streaming or warehouse-native analysis, or on stated API limits, so my cross-check against our own data would end at a CSV. 2 4

Report an error

The E-Commerce Manager

Raw data export to CSV plus API access and ninety-plus integrations on every plan means a test result can be checked against my own numbers, which I insist on. We found no public information on visitor-level streaming to a warehouse, on API limits, or on warehouse-native analysis. 2 4

The CRO Consultant

Every plan carries ninety-plus integrations, API access and an MCP server, and raw data export in CSV is on the pricing page — enough to get results and data out for a second opinion. But we found no public information naming the analytics and tag-management tools, on visitor-level streaming or warehouse-native analysis, or on stated API limits, which is where the re-analysis story would need to go next. 2 3 4

The Data Protection Officer

Ninety-plus integrations, API access and an MCP server are included on all plans, together with raw-data CSV export, so a buyer can pull results out of the dashboard.

The Skeptic

Raw-data CSV export and API access on every plan, with ninety-plus integrations and an MCP server, are enough to pull a result out of the vendor's dashboard and check it.

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.

Visitor data from customer sites is stated to stay on German servers in Frankfurt on every plan, which is what matters most for our visitors. The contracting entity is Convert Insights, Inc. of Delaware, customer account data is stored in the US under the Data Privacy Framework, and snippet delivery runs on Akamai; we found no public information confirming a published subprocessor list. 2 3 4

Report an error

The E-Commerce Manager

The line that matters to me is stated plainly — visitor data stays in Europe on German servers, and Frankfurt hosting ships on every plan. Against that, the contract is with a Delaware entity under Delaware law, my account data sits in the US under the Data Privacy Framework, the snippet rides Akamai, and the list of authorised third parties the privacy notice points to is not among the captured pages. 2 3 4

Report an error

The CRO Consultant

The visitor-data half is stated plainly and would help in an EU pitch: EU-based Frankfurt servers on all plans, and visitor data stays in Europe on German servers. The contracting side pulls the other way — Convert Insights, Inc. of Delaware under FTC enforcement, customer data stored in the US under the Data Privacy Framework — and the third parties who may track visitors appear only as a list reference we could not see, so the chain is only partly defensible. 2 3 4

Report an error

The Data Protection Officer

Visitor data is documented to stay in Europe on German servers, which is the part I weigh highest for a script that runs on every visitor; however the contracting entity is Convert Insights, Inc. of Wilmington, Delaware under Delaware law and FTC oversight, and customer account data is stored in the US under the Data Privacy Framework. We found no published subprocessor list that includes the Akamai CDN delivering the test content, while the privacy notice states that authorized third parties may track and store visitor information including IP addresses. 2 3 4

Pricing transparency

panel disagrees 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.

The Growth Lead

The traffic metric, tier limits, exact overuse rates ($399 per 100K on Growth, $699 per 250K on Pro, switchable off), VAT by billing location and the $1000/year per custom domain add-on are all public. The Enterprise tier is price on request and the terms allow unspecified additional fees, so I could compute our annual invoice only up to the Pro tier. 2 4

Report an error

The E-Commerce Manager

The traffic metric, per-tier limits and overuse rates are public, overuse can be switched off, and legacy plans are honoured — that keeps a December traffic spike from re-tiering my invoice. But we found no public information on the base tier prices or seats, the terms say some features may require additional fees, and the Enterprise tier is price on request, so the annual invoice is not computable from public pages alone. 2 4

Report an error

The CRO Consultant

The criterion my clients care about most, and it mostly delivers: the traffic metric is monthly tested users with per-tier yearly caps, overuse is priced at "$399 per 100K" on Growth and "$699 per 250K" on Pro and Enterprise and can be turned off, VAT treatment is stated, and a "$1000/year per domain" add-on is published. Held below the top because the Enterprise tier is price on request, some features carry unspecified additional fees, multi-year discounts are something you ask about, and we found no public information on the base subscription figures for Growth and Pro. 2 4

But we found no public information on the base tier prices in the captured pages, the top tier is price on request only, and the terms reserve additional fees for some features — so a buyer cannot compute the full annual invoice from what we saw. 2 4
