Gemini Cross-Device Handoff Testing for SaaS Funnels

When this matters

• A user asks Gemini to summarize a plan on mobile, then opens the product on a laptop.
• A checkout link, trial link, or account recovery link is handed off between devices.
• A product page needs its main offer and constraints to be answerable without confusing the user.
• A support or onboarding flow depends on a user continuing a partially completed form.

How to check it

1. Prepare a mobile starting point with a real URL, app deep link, or pricing screen.
2. Identify what an AI assistant should extract: offer, price, limit, eligibility, deadline, and next action.
3. Continue the same journey on a laptop and compare state, copy, and CTA continuity.
4. Capture any mismatch between AI-readable summary and the actual checkout or signup page.
5. Assign fixes to content, product, identity, or checkout owners.

Common risks

• Important plan conditions sit in images, accordions, or vague marketing copy.
• The laptop page changes the selected plan or billing interval.
• A deep link opens the wrong route, region, language, or workspace.
• AI summaries recommend an action that the laptop page does not make obvious.
