Information hierarchy

72Fair

Does the design help or inhibit what the page is trying to say?

Information hierarchy annotations on the desktop capture

Header Get Started button — Dark green button nearly disappears into the dark navy sky background, and it duplicates the hero CTA at equal weight.
Top quiz banner — A second conversion path ('Take the quiz') sits above everything, competing with 'Get started' before the value prop is read.
Hero Get started button — Dark green on mid-blue sky yields low contrast for the single most important element on the page.
Nav pill bar — Five nav links float in a highlighted pill at the fold's center-top, drawing eye-level attention away from the headline.

CTA

72Fair

Copy, size, verb, cost-feel — does the primary CTA earn the click?

Problems

generic label, no payoff named
label case drift: hero vs nav
quiz bar competes with hero CTA

Value props

78Fair

Title, subtitle, hero — do they sell the product's true value?

Gutgutgoose’s headline sellsBetter gut health with personalized probioticsNo more guessing which probiotic might work. Test your microbiome with full DNA sequencing, get a made-to-order formula, then retest for proof of which strains colonized.

Working

Subhead names test-formulate-retest mechanism
"No more guessing" hits real frustration
Product jar hero matches the claim

Could improve

Headline is generic to any probiotic
No numbers: strains, days, users
Emotional payoff of relief unstated

Mobile web

78Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture

Broken word wrap — "made-to-order" splits mid-word into "m ade-to-order", reading as a rendering bug in the key value copy.
Get Started button — Desktop-proportioned pill floats centered; on mobile it should stretch near full-bleed for the thumb.
Quiz promo bar — Sticky top bar adds a second competing CTA above the logo and eats first-viewport height.
