As a senior UX designer with extensive experience in conversion-focused, mobile-first design, here’s my critique and recommendations to improve your homepage’s clarity, visual hierarchy, and sign-up conversion.

Assumptions I’m making

• Primary goal: drive sign-ups for your product (free trial, demo, or email capture).
• Current issues: high bounce from ad traffic suggests mismatch between ad promise and hero content, weak above-the-fold clarity, and/or friction in the first interaction.
• Mobile is the primary entry point from ads.

Top priorities to fix first (in order) 1) Above-the-fold clarity and CTA

• One headline, one promise: Your hero should state what you do, for whom, and the core outcome in one sentence. Avoid clever taglines.
• Subhead supports the headline with a tangible benefit or proof point.
• One primary CTA in the hero (e.g., “Start free trial” or “Book a demo”), visible without scrolling on mobile. Pair with a trust nudge: “No credit card required” or “Takes 2 minutes.”
• Remove competing actions (e.g., “Learn more,” secondary links) from the hero on mobile. Keep a secondary path under the fold.

2) Visual hierarchy

• Use a single visual focus: either a product screenshot with a highlight of the “aha” moment or a short looping demo. Blur or dim backgrounds so the headline and CTA dominate.
• Size hierarchy: H1 > Subhead > CTA. Keep line lengths 45–65 characters for readability. On mobile, stack elements vertically with generous spacing.
• Contrast: Ensure at least a 4.5:1 contrast ratio for text, and make the primary CTA a distinct color that isn’t used elsewhere.

3) Message match from ads

• Mirror ad keywords and value props in the hero headline and first section. If ads promise “Automate invoices in 5 minutes,” your hero should repeat that phrase and show that workflow.
• Create campaign-specific variants of the hero for major traffic sources.

4) Social proof placed strategically

• Put one high-credibility trust element within the first viewport on mobile: customer logos or a short testimonial with measurable result.
• Deeper proof (case studies, ratings, security badges) goes in a section just below the hero. Keep testimonials specific and scannable: “Cut onboarding time by 42% in 3 weeks.”

5) Simplify navigation (especially on mobile)

• Collapse navigation into a hamburger with a single primary CTA in the header. On desktop, limit top nav to 3–4 items plus the CTA.
• Avoid sticky nav clutter; make the sticky element the CTA if anything.

6) Form and friction reduction

• If the goal is account creation, use email + passwordless (magic link) or third-party auth to reduce fields. Delay non-critical fields until after activation.
• If booking demos, embed a calendar inline under the CTA to reduce steps.
• Show progress: “Step 1 of 2” and expected time to complete.

7) Content structure for scroll behavior

• Section order:
  1. Hero: problem, promise, primary CTA.
  2. Social proof: logos or quick metrics.
  3. How it works: 3-step visual with a single sentence each.
  4. Key outcomes: 3 benefit blocks, each tied to a metric or scenario.
  5. Deep proof: testimonial, rating badges, case study snippet.
  6. Objection handling: pricing transparency, security, integrations, support.
  7. Final CTA: repeat with a slightly different angle (“Get started free”).
• Keep each section skimmable: strong headers, 1–2 lines of text, one visual.

8) Mobile-first layout specifics

• Tap targets minimum 44px height, 16–20px body text, 24–32px headings.
• Above-the-fold should show headline, subhead, and CTA without cropping.
• Avoid carousels; use stacked cards with lazy-loaded images.
• Keep images under 150KB each; compress and use modern formats (WebP/AVIF).
• Defer non-critical scripts; remove animation bloat that janks scroll.

9) Performance and perceived speed

• Aim for LCP under 2.5s on mobile: serve a lightweight hero image, preconnect to critical domains, and use server-side rendering where possible.
• Show instant UI feedback on CTA press: loading state, microcopy confirming next step.

10) Accessibility and trust

• Alt text for images, proper semantic headings, focus states on buttons.
• Clear privacy statement inline near forms; link to security page if relevant.
• Use real people and real company names in testimonials; avoid stock imagery.

Copy guidelines to improve clarity

• Headline formula: [Audience] + [Outcome] + [Time/effort saved] Example: “Automate invoice collection for SMBs in under 5 minutes.”
• Subhead: How it works or a proof claim. Example: “Connect QuickBooks, set rules once, and get paid 2x faster.”
• CTA microcopy: action + value + friction reducer. Example: “Start free • No card required.”
• Replace feature lists with benefit-led bullets tied to outcomes:
  • “Reduce manual follow-ups” → “Cut overdue invoices by 35%”
  • “Custom workflows” → “Handle 10x more invoices without extra hires”

Common pitfalls causing bounce and low conversion

• Vague or jargon-heavy hero that doesn’t align with ad promise.
• Multiple CTAs competing above the fold.
• Hidden pricing or unclear next step.
• Dense paragraphs; no scannable structure on mobile.
• Decorative hero visuals that don’t clarify the product.

Quick diagnostic checklist

• Can a new visitor understand what you do and the primary action within 5 seconds on mobile?
• Is there exactly one primary CTA above the fold, and is it tappable without zoom?
• Does the hero repeat core keywords from the ads?
• Do you show at least one trust signal in the first viewport?
• Is the first interaction a single tap and less than 2 seconds to respond?

Test plan (iterate quickly)

• A/B test hero headline variants tied to ad intent.
• A/B test single CTA vs. multiple options above the fold (expect single CTA to win).
• Test “No credit card” and social proof placement in the hero.
• Test inline calendar booking vs. “Contact sales.”
• Track: LCP, bounce rate for top landing URLs, click-through on hero CTA, form start and completion, and time to first value post-signup.
