RECOMMENDED — H1 with value prop
Add H1 headlineAdd value prop
FixAdding a clear H1-style headline and value proposition near the search box immediately communicates Yahoo's purpose and guides users to their goal.

The inventory shows h1s: [] and the body sample begins with 'Search Query for Search the web' and navigation links, with no headline or subheadline explaining what Yahoo offers or how to get started.
The homepage has no H1 and the H2s are generic ('Trending', 'Explore More', 'For You'), with no tagline or explanation of Yahoo's value.

Current state
h1: None; cta: Sign in, Search the web; notes: The page is a portal with many links and widgets, but no clear hero message or primary action for new or returning visitors.
Change
h1: Your world, one search away; cta: Search the web; notes: Add a concise H1 that states the core value (search, news, finance, mail) and a subheadline that addresses common visitor intents, e.g., 'Get the latest news, check your email, and manage your finances—all in one place.'
Acceptance criteria
GIVEN a first-time visitor on the affected page
WHEN the change is live
THEN Add a concise H1 that states the core value (search, news, finance, mail) and a subheadline that addresses common visitor intents, e.g., 'Get the latest news, check your email, and manage your finances—all in one place.',
with no regression at 375px and 1280px widths.

Rollback
Feature-flag the change; revert the flag if the primary metric
drops for 3 consecutive days.
1,000 visitors × baseline conversion × relative lift
= per 1,000 visitors at an assumed 2.00% baseline conversion rate and a 1.0-5.0% relative lift
The 1.0–5.0% relative-lift band is an assumption bounded by severity (High), not a prediction.
The baseline conversion rate is an assumption — the client did not supply one, so an industry-typical 2.0% is used and labelled as such.
Why the range is conservative: Across 127,000 experiments, 12% produced a statistically significant improvement on the primary metric; a healthy programme win rate is 10-30%. Winning tests also overstate their true effect, so treat this as the prize if the change works — never expected revenue.

Sample size math
Two-proportion z-test, the standard pre-test sample-size calculation:
n = [z₀.₀₂₅·√(2·p̄·(1−p̄)) + z₀.₂₀·√(p₁(1−p₁)+p₂(1−p₂))]² / (p₁−p₂)²
Baseline conversion
2.0% (assumed)
Significance / power

Sample per variant, 5.0% lift

Halving the minimum detectable effect roughly quadruples the sample required, which is why the conservative figure is so much larger.
What PXL is
PXL is CXL's prioritisation framework: binary questions instead of subjective 1–10 guesses, weighted toward evidence.
Findings discovered by inspection score zero on all four evidence questions — that is the honest signal, not a defect. Findings verified by direct measurement earn the extension point and, where real-user field data is involved, the analytics point.
