# Choice overload in nav — dev spec
Site: yahoo.com · Priority 6 · High · Effort: Medium (2-5 days)

## Problem
The homepage navigation presents a high number of links and multiple skip links, potentially overwhelming users and diluting focus on primary actions.

## Evidence (from the live site)
> Nav_items include 'News', 'Finance', 'Sports', 'Mail', 'Sign in', 'Trending' plus skip links; n_links: 211; body_sample shows multiple sections like 'Trending', 'Weekend Reads', 'Explore More', 'For You', 'Spotlight Videos', 'Popular Games'.

## Current state
h1: None; cta: Sign in, See more stories on Yahoo 100, See forecast; notes: Homepage has no H1, many links and sections, potentially causing choice overload.

## Required change
h1: Yahoo; cta: Sign in, Search; notes: Simplify navigation to core items, reduce link count, and add a clear H1 for context.

## Acceptance criteria
- GIVEN a first-time visitor on the affected page
- WHEN the change is live
- THEN Simplify navigation to core items, reduce link count, and add a clear H1 for context.
- AND no layout regression at 375px / 768px / 1280px
- AND the changed control is keyboard-reachable with an accessible name

## Tracking
- Fire `cro_choice_overload_in_nav` on interaction with the changed element
- Verify the event fires in BOTH variants before opening traffic

## Test plan
- Two-proportion z-test, 95% significance, 80% power
- 315,206 visitors per variant to detect a 5.0% relative lift
- Run at least one full business cycle; duration depends on traffic

## Rollback
Feature-flag the change; revert if the primary metric drops for 3 consecutive days.
