Mobile browser extension KPIs
Mobile browser extension KPIs should prove a real browser-first social reply segment before Safari iOS or Firefox Android extension work begins. The strongest KPIs are mobile browser social sessions, visible context capture success, selected copy fallback completion, extension permission comprehension, browser-specific support burden, and clear separation from native X app composer workflows.
Last updated: July 11, 2026. These are rollout metrics, not customer outcome claims.
Measurement purpose
What this metric set should prove
Use these KPIs to decide whether mobile browser extensions are worth building after mobile web and native learning. Browser extensions help browser sessions; they should not be measured as a substitute for Android or iOS native app composer workflows.
Core metrics
Which events should be measured?
Visible context capture
Measures whether the extension can capture enough visible page context for useful drafts.
Suggested event: mobile_browser_context_capture_succeeded
Selected copy fallback
Measures whether users can complete the workflow when direct insertion is limited.
Suggested event: mobile_browser_selected_copy_completed
Support burden
Tracks browser-specific QA, review, permission, and page-structure issues before roadmap commitment.
Suggested event: mobile_browser_extension_support_issue
Leading indicators
What should move before roadmap priority changes?
Browser traffic contains social replies
Browser sessions matter only when users are actually replying from mobile browser social pages.
Context capture is stable
The page structure should provide enough visible context without hidden account control.
Copy fallback completes the job
Selected copy should complete the workflow when insertion is brittle or unavailable.
Native mismatch is documented
Browser extension metrics should not be described as native app composer success.
Decision rules
How should these metrics guide the roadmap?
Build only for browser-first users
Do not prioritize mobile browser extensions unless browser-first social reply sessions are measurable.
Keep mobile web fallback
Mobile web should remain the broad fallback when extension behavior is narrow or unstable.
Do not replace keyboards
Browser extension KPIs should not displace Android keyboard or iOS keyboard plus Share Extension metrics.
Watch maintenance cost
High browser-specific support burden should delay extension roadmap scope.
Instrumentation guardrails
Keep metrics honest
Keep metrics as product signals
Label metrics as TypeToSell rollout and safety signals, not customer outcome claims, revenue lift, reply-rate guarantees, ranking proof, ratings, or reviews.
Separate generated from selected
Track generation starts separately from selected copy or insertion so the team does not confuse curiosity with real workflow completion.
Keep final posting outside TypeToSell
Measure draft handoff and copied or inserted text, but do not instrument TypeToSell as the system that presses the final public platform button.

FAQ
Metrics questions
What KPI proves mobile browser extension demand?
Browser-first social reply sessions plus visible context capture and selected copy completion prove demand.
Do browser extension KPIs replace keyboard KPIs?
No. They measure browser sessions, not native Android or iOS social app composers.
When should Safari iOS and Firefox Android extensions come?
They should come after mobile web and native learning unless browser-first reply usage is already strong.
