What Reliability Means at Convert

Reliability is not a feature. It is four decisions, made before a single visitor is bucketed.

Is the data clean? Is the experiment delivered as designed? Does the infrastructure stay up? Is visitor privacy protected by architecture, not only by promise?

Convert Experiences treats all four as engineering problems. Each one has an answer you can check. The sections below take them in turn.

Measurement Integrity Gives You Experiment Reports You Can Trust

A report is only as good as the data under it. Convert Experiences gives you three controls over what reaches your results. Non-human and internal traffic is excluded. Assignment is deterministic, so visitors stay put. And a statistical check tells you when the split has gone wrong.

How Convert Experiences keeps bots out of your results

A bot assigned to a variant still counts. It inflates your sample and pushes tests to “winner” on noise. What matters is where the filter sits. Filter late, and the bot is already counted; filter early, and it never enters the pipeline.

Convert Experiences filters early. A bot check runs on every request, before any database write, and known bots are discarded on the spot. This catches the bots that announce themselves, such as search crawlers, AI crawlers like GPTBot and ClaudeBot, HTTP libraries, and monitoring tools.

It does not catch a scraper running real Chrome on a residential IP. That harder category needs analysis across many requests, and it is what Convert is building toward.

How Convert Experiences assigns the same visitor to the same variation

In the Convert Experiences JavaScript SDK, assignment is deterministic. The SDK hashes the visitor ID with MurmurHash3 and maps the result into a 0–10,000 range. It then picks the bucket by checking that value against the variation percentages you set.

The same visitor always lands on the same variation. The hash respects your traffic allocation, so randomization holds for the life of the experiment.

Browser-based Web Testing works differently. Convert Experiences stores the assignment in a first-party cookie, so a returning visitor stays in the variation they first saw.

It’s important to note that Convert advises against changing traffic distribution mid-test, because reallocating a running experiment compromises the data that follows.

How Convert Experiences detects a broken traffic split

Convert Experiences checks whether your traffic split is real.

The Sample Ratio Mismatch (SRM) check compares the visitors assigned to each variation against the split you configured. It uses a Chi-square goodness-of-fit test, and it handles uneven splits. When the gap is wide enough, the check fires at 99% confidence. An SRM tag then appears on the experiment report, telling you to review the setup before you trust the result.

You enable SRM checks per project, under Project Configuration > More Settings.

This matters because a bad split is how tracking failures, redirect issues, targeting errors, and randomization bugs manifest. Catching one early is the difference between a sound decision and a mistake.

Robust Infrastructure Ensures Your Experiments Deliver as Expected

An experiment that renders wrong is worse than no experiment. It still gives you data, and you will still act on it. Convert Experiences is built so that what you configure is what your visitors get.

One experiment, six runtimes, the same bucketing

Convert Experiences ships six production SDKs. JavaScript covers the web, client-side, and Node. Android and iOS cover mobile apps. PHP, Python, and Ruby cover server-side backends.

All six run A/B tests, feature flags, and experience bucketing. The mobile and server SDKs use the same bucketing as the JavaScript SDK. A visitor placed in a variation in one runtime lands in the same variation in the next.

Your full-stack experiment does not work in one stack and derails in another.

Integrations that keep your tracking aligned

Your experiment data is only useful if it lands cleanly in the tools you already run. Convert Experiences was the first A/B testing platform with an official GA4 integration. It pushes experiment and variation IDs straight into GA4, ready to export to BigQuery.

Beyond analytics, Convert Experiences connects to 90+ tools. Its API, webhooks, and GTM Data Layer pipe experiment data into BI platforms like Looker Studio and Power BI. Warehouses such as BigQuery and Snowflake connect via Segment and Stitch.

Your results reach your stack the way you already work, without a brittle hand-built bridge in the middle.

Where your data lives

Convert Experiences hosts production servers and databases on Amazon Web Services, with the login site hosted separately on Hetzner for GDPR compliance. Convert Experiences runs on carbon-neutral servers.

Production infrastructure runs in highly available configurations spread across two availability zones. Disaster-recovery measures are tested regularly, and an on-call team is staffed around the clock.

Decisions made at the edge

Convert Experiences integrates with Cloudflare Workers. The variation decision happens at the edge, before the page reaches the browser.

Your visitor receives the chosen variant directly. Nothing waits for client-side JavaScript to load, evaluate, and rewrite the DOM. That removes the flash of original content (AKA flicker) that client-side testing risks.

The result is minimal latency and no flicker.

First-party cookies that survive the browser wars

Convert Experiences supports custom domains. The tracking script and its requests come from your own subdomain, so the visitor cookie stays first-party.

First-party cookies survive Safari’s Intelligent Tracking Prevention and cookie partitioning. Your assignment and your measurement hold up in browsers that restrict third-party tracking. There is no third-party dependency to lose.

Script delivery, and the trade-off others rarely talk about

Convert Experiences gives you three ways to load the script, so delivery matches what your site needs.

  • Sync with a body-overlay anti-flicker (the default): applies variations before render and stops flicker, but it can cost you Core Web Vitals,
  • Async with built-in anti-flicker: feels faster, and accepts some flicker risk in exchange, and
  • @convertcom/tracking-react / -vue: for single-page applications.

We don’t hide the trade-off.

The snippet is 93 KB gzipped at baseline, and roughly 95–110 KB with three to five experiments. It arrives as one bundle, upfront, with no hidden runtime fetches.

That is a bigger initial payload than a loader-based rival advertises. It is also why experiment behavior stays predictable. Nothing is deferred to a request that may not finish before your visitor scrolls.

Human-First. The Choice to Use AI is Always Yours.

Convert Experiences builds AI with seat belts. You switch on every AI feature, and you direct it. No AI feature in Convert Experiences changes a live experiment, rewrites your site, or publishes anything on its own.

A person decides. Each seat belt is a specific mechanism you can point to. Here are five.

Sign-off before anything ships

With Request Approval System in Convert, nothing goes live until someone signs off. Convert Experiences can hold any attempt to activate, pause, or edit a live experience for review, and the same review applies whether a person or an AI collaborator made the change.

No one can approve their own work, and every decision is logged for a client or compliance review. Available in beta on Convert Experiences Pro and Enterprise plans.

Every decision is logged

Generation is user-initiated

The AI Wizard in the Convert Experiences Visual Editor writes nothing on its own. You select the text. You pick a tone, or write your own prompt. You click Generate. Then you decide whether to apply a suggestion.

Nothing reaches a variation until you put it there.

Insight features observe, they do not act

Smart Recommendations tell you when a variation is winning, losing, or short of the visitors it needs. Convert Signals® shows you sessions where visitors hit friction.

You enable both at project level. Both stop at the observation. Neither one changes an experiment, alters targeting, or touches your site.

Both stop at the observation

Automation is opt-in and scoped

The Convert MCP server connects AI clients such as Claude or Cursor to your Convert data. It is opt-in.

Access is reporting-oriented by default. Write access needs elevated configuration, and you set it deliberately. The model drafts, checks, and verifies work. You decide what gets created, updated, or activated.

Reporting-oriented by default

The assistant plays by the same rules

Convert Experiences includes Convert Intelligence®, an in-app AI assistant, in beta as of 2026. Everything above applies to it. It suggests and drafts, and you decide what happens. The Request Approval System governs its changes exactly as they govern yours.

You decide what happens

Privacy by Design

Convert Experiences treats privacy as architecture. It uses first-party cookies, needs no personal data to run, and honors the Do Not Track header. Compliance staff sit inside the development team, reviewing features before release rather than after.

Consent, enforced before collection

Convert Experiences can hold back cookie writing until a visitor consents. In strict mode, it holds back the experiment too. A visitor who has not consented is neither tracked nor bucketed.

You pick the mode that matches your obligations.

Warnings before mistakes

Convert Experiences surfaces GDPR warnings in-app, flagging configuration choices with privacy implications before an experiment goes live rather than after a regulator asks.

What Convert Experiences complies with

Convert Experiences has been GDPR-compliant since May 2018, CCPA-compliant since January 2020, and LGPD-compliant since August 2020. International transfers are covered by EU Standard Contractual Clauses and the EU-US and Swiss-US Data Privacy Frameworks.

Tiffany Fortune

Chief Operating Officer, Convert

Convert Experiences is a link in your privacy chain. We built it so that adding Convert Experiences to your stack strengthens your posture rather than introducing a new liability.

This commitment predates the regulation

GDPR took effect on 25 May 2018. Convert was arguing for privacy-first A/B testing months before that. In February 2018, Convert’s CEO published a guide to buying GDPR-compliant testing software, written to help teams choose privacy-by-design tools ahead of the deadline. The commitment runs back further still. Convert was a registered EU-US Privacy Shield participant as far back as 2017, making Convert’s privacy posture almost a decade old. This has never been a compliance exercise for Convert. It was the design from the start.

Reliability, Trust and Performance of Convert Experiences: FAQ

Is Convert Experiences reliable?

Convert Experiences engineers reliability across four layers: exclusion of bot and internal traffic from experiment reporting, deterministic visitor bucketing, highly-available infrastructure with regularly tested disaster recovery, and privacy enforced by architecture. As of 2026, Convert Experiences has optimized 40,000+ websites over 15 years with zero security breaches.

How does Convert Experiences keep experiment data clean?

Convert Experiences filters bots at ingest. A bot check runs on every request before any database write, so known bots such as search crawlers, AI crawlers, HTTP libraries, and monitoring tools are discarded before they are ever counted or bucketed. Convert Experiences also runs a Sample Ratio Mismatch check that flags when the observed traffic split diverges from your configured allocation.

How does Convert Experiences detect Sample Ratio Mismatch?

Convert Experiences compares observed visitors per variation against your configured allocation using a Chi-square goodness-of-fit test that accounts for unequal splits. When the mismatch is large enough, the check triggers at 99% confidence, and Convert Experiences displays an SRM tag on the experiment report. SRM checking is enabled per project under Project Configuration > More Settings.

Does Convert Experiences slow down my site?

The Convert Experiences snippet is 93 KB gzipped at baseline, rising to roughly 95-110 KB with three to five experiments, delivered as a single upfront bundle with no hidden runtime fetches. Convert Experiences offers synchronous, asynchronous, and single-page-application loading options, so teams choose their own trade-off between flicker prevention and Core Web Vitals impact.

Which SDKs does Convert Experiences support?

In July 2026, Convert Experiences ships six production SDKs. That includes JavaScript (client-side and Node), Android, iOS, PHP, Python, and Ruby. All six support A/B testing, feature flags, and experience bucketing. The mobile and server SDKs share bucketing parity with the JavaScript SDK, so a visitor is assigned consistently across runtimes.

Is Convert Experiences GDPR compliant?

Convert Experiences has been GDPR-compliant since May 2018 and is also CCPA- and LGPD-compliant. Convert Experiences uses first-party cookies, does not require personally identifiable information to operate, honors the Do Not Track header, and can withhold both cookie writing and experiment execution until a visitor consents.

What security certifications does Convert Experiences hold?

Convert Experiences is ISO 27001 certified by InterCert and SOC 2 Type 2 attested. Convert Experiences is designed to support HIPAA compliance for covered entities and business associates, and follows PCI-DSS principles. Convert Experiences maintains a legacy of zero security breaches.

Where does Convert Experiences host my data?

Convert Experiences hosts production servers and databases on Amazon Web Services, with the login site hosted separately on Hetzner for GDPR compliance, and runs on carbon-neutral servers. Production infrastructure is spread across two availability zones with regularly tested disaster recovery.

Do I have to use AI features in Convert Experiences?

No. Every AI capability in Convert Experiences is opt-in and user-directed. The AI Wizard generates copy only when you select text and request it. Smart Recommendations and Convert Signals surface observations without changing anything. The Convert Experiences MCP server is reporting-oriented by default, with write access requiring deliberate configuration.

How fast is Convert Experiences support?

Convert Experiences delivers a median first-response time of under 2 minutes 44 seconds, against a SaaS industry average of 2.6 hours on Zendesk benchmarks. Support is in-house and staffed by experimentation specialists, and every Convert Experiences plan includes free onboarding.

What independent reviews, certifications, or compliance standards verify Convert’s reliability?

Convert holds GDPR/CCPA compliance and high reviews on G2 (4.7/5) and TrustRadius (9.9/10).

How long has Convert been in operation, and which types of customers use it?

Founded in 2009, Convert serves SMEs & CRO agencies across e-commerce, SaaS, and publishing.

Independent CRO consultants, marketing & growth leaders of lean teams, and developers who code A/B tests benefit from using the platform.

How does Convert demonstrate transparency in pricing and data handling?

Convert publishes clear pricing based on Monthly Tested Users (MTUs) rather than feature gating or hidden fees, and plans scale predictably without forced upgrades. On the data side, Convert documents its privacy practices in detail: it uses EU-based servers, relies on first-party cookies, anonymizes visitor data, and respects browser privacy settings such as Do Not Track (DNT) and Global Privacy Control (GPC). This transparency helps customers understand both costs and compliance from the start.
