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 — 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.
The CRO Consultant
The homepage positions a server-side programme across native apps, websites, email and CRM, and algorithms with multiple SDKs and a searchable experiment hub for documentation and decisions, which is broader than client-side-only tools. But the SDKs are marketing copy rather than documentation, and we found no public information on multivariate or multi-page tests, audience targeting, personalisation, or feature-flag mechanics such as holdouts and mutual exclusion, so I cannot tell a client which test types the platform actually supports. 1 3
