A/B Testing and CRO News: June 2026

The first half of June brought practical changes rather than splashy launches: the VWO and AB Tasty merger reached the stage where login URLs actually change, and Optimizely shipped two updates, one aimed at AI search visibility and one that finally gives its Opal assistant an EU hosting option. Here is what happened and what it means if you run an experimentation programme.

VWO moves to app.wingify.com on 13 June

VWO confirmed on 10 June that its application is moving from app.vwo.com to app.wingify.com, with the switch happening at 11:00 PM PDT on 13 June 2026. This is the first visible customer-facing step of the VWO and AB Tasty merger under the unified Wingify brand. Credentials carry over and running experiments, SmartCode installations, and REST API endpoints are unaffected, but you will need to update password manager entries, re-register any passkeys at the new domain, and ask IT to whitelist the wingify.com, wingify.net, wingify.io and wingify.ai domains. If your firewall or corporate proxy blocks unknown domains, sort the whitelist before Friday rather than after a test stops tracking. Details are in the VWO product update.

Optimizely launches a full AEO platform

On 10 June Optimizely announced a complete Answer Engine Optimisation platform, built around Agent Visibility Analytics and a partnership with Conductor. The pitch: log-level data on how AI agents actually crawl and use your content, plus agents that benchmark your share of voice in AI answers against competitors and flag topics where you are losing. For CRO teams this matters because a growing slice of buying journeys now starts inside an AI answer rather than a search results page, which changes which landing pages get traffic and therefore which tests are worth running. If you are weighing up the wider Optimizely suite, our Optimizely alternatives guide covers where it fits. The announcement is on PR Newswire.

Optimizely Opal adds EU hosting and document editing

In its 4 June release, Optimizely added an EU hosting region for Opal, its AI assistant, so European customers can keep Opal data inside the EU. The same release lets Opal read, create and edit .docx and .pptx files. The data residency change is the bigger deal for UK and EU buyers: procurement and legal teams have been blocking AI assistant rollouts on exactly this point, and an EU region removes a common objection for teams that wanted Opal alongside Optimizely Web Experimentation. If data residency has kept Optimizely off your shortlist of A/B testing tools, it is worth a fresh look. The release notes are in Optimizely’s update post.
