Render-blocking requests

Est savings of 780 ms

Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.

01 / WHAT WORKS

What makes it work

Distinctive editorial serif typography and numbering

Employing Songti SC for prominent 89.6px headings paired with traditional Chinese numerals (壹, 贰, 叁) gives the manifesto an authentic literary weight that stands apart from generic SaaS landing pages.

Transparent spec row directly under the hero

The clean horizontal grid immediately communicates platform support (iOS 26, macOS 26), local-first privacy, BYOK flexibility, and the non-subscription pricing philosophy without hiding crucial details behind marketing copy.

02 / NEXT STEPS

Where to go next

  1. 01

    Replace the hero secondary Privacy button with product visual proof

    Pairing 'Privacy Policy' side-by-side with 'Join TestFlight' in the primary viewport wastes prime conversion space on legal terms instead of previewing the keyboard or dictation workflow.

    Keep 'Join TestFlight' as the primary solid blue CTA, demote 'Privacy Policy' to the global footer or spec bar, and introduce a secondary 'View Demo' or interactive keyboard screenshot trigger right below the spec grid. Verify on 1440px and 390px screens that both visual UI previews and beta entry points remain prominent.

  2. 02

    Clarify TestFlight beta readiness and onboarding guidance

    Tapping '加入 TestFlight' currently sets no expectation regarding slot availability, installation prerequisites, or build limitations.

    Add a micro-status badge above or beside the hero CTA (for example: TestFlight public beta open, requires iOS / macOS) and specify clear fallback instructions or an email notification form when slots fill up.

03 / DESIGN LANGUAGE

A secondary button beside the main download CTA should demonstrate product functionality rather than sending early prospects into legal terms.

The detail behind the report

Conversion2 observations

Share card is incomplete

High

A blank or generic unfurl on X, Slack, or WeChat wastes the click you already earned. This is distribution, not decoration.

Set og:title, og:description, and a 1200x630 image that matches the live headline.

og:title=yes og:image=no

No way to reach a human

Medium

A stranger who wants to buy, ask, or complain has nowhere to go. That is a conversion leak and a trust leak.

Put a mailto, a form that works, or a real social handle in the footer. One is enough.

No HSTS header

Medium

Without Strict-Transport-Security, a first visit can still be downgraded to http. Browsers will not pin HTTPS.

Set Strict-Transport-Security: max-age=31536000; includeSubDomains at the edge.

No Content-Security-Policy

A CSP is the standard way to limit script sources. Vibe-coded pages often load anything, including injected scripts.

Start with a report-only CSP, then default-src 'self' and an explicit script-src.

No X-Content-Type-Options

Without nosniff, browsers may interpret a file as a different type than you sent. It is a one-line header.

Set X-Content-Type-Options: nosniff.

No Referrer-Policy

The default referrer can leak internal paths and query strings to third parties.

Set Referrer-Policy: strict-origin-when-cross-origin.

Refactor the hero action row on https://ime.umate.ai/. Retain all existing design tokens: paper background #fafafa, ink text #111111, accent blue #2f6bff, font stack with Songti SC headings and PingFang SC body. Keep the primary CTA '加入 TestFlight' with its rounded 8.8px border-radius and arrow icon circle. Relocate the standalone '隐私政策' button from the hero action row to the footer and the spec bar section. Replace that secondary hero button slot with an interactive visual preview or floating keyboard screenshot trigger ('查看演示' / 'View Demo'). Ensure responsive alignment on desktop (1440px) and mobile (390px).
