あなたのSquarespaceサイトは毎時間顧客を失っています
より低い品質のコンテンツでも上位にランクされている競合他社を見ているなら、8秒の読み込み時間がその理由です。
Why leave Squarespace?
- Downloads 300–600KB of platform JavaScript on every page load, slowing mobile Time to Interactive to 6–9 seconds
- Delivers Lighthouse scores of 35–60 on mobile, triggering Google's speed-based ranking filters
- Locks your design inside template constraints that prevent custom layouts, animations, or component logic
- Charges $23–65/month for a subscription model where you never own the codebase or deployment pipeline
- Loads full commerce functionality (cart, checkout, inventory scripts) on non-commerce pages, bloating every request
- Blocks custom API integrations, headless CMS connections, and server-side logic your business model needs
What you gain
- Lighthouse 95–100 mobile scores from day one, passing Core Web Vitals and avoiding speed-based ranking penalties
- Full design freedom to build custom layouts, animations, and interactions without template system limits
- You own the entire codebase and can deploy to any host, switch agencies, or hire in-house without vendor lock-in
- Hosting costs drop to $0–20/month on Vercel or Netlify versus $23–65/month recurring Squarespace fees
- Custom functionality -- headless CMS, third-party APIs, dynamic pricing, member portals -- without platform restrictions
- Sub-2-second page loads that recover 5–12% conversion rate lost to Squarespace's JavaScript bloat
Squarespaceのパフォーマンス問題
Squarespaceは美しいサイトを構築します。同時に、すべてのビジターに膨大な量のJavaScriptを配信しています -- Squarespaceプラットフォームフレームワーク、すべてのテンプレートスクリプト、およびコマース機能は、ページがそれらを使用しているかどうかに関わらず読み込まれます。Squarespaceサイトのモバイル Lighthouse スコアは通常35～60の範囲です。
オーガニックサーチに依存するビジネスにとって、これは実際の問題です。より高速なスタック上の競合他社は、より優れた Core Web Vitals により同等のコンテンツで上位にランクされています。
Squaespaceからの移行に関わること
Squarespaceはブログ記事用のコンテンツエクスポート機能（XML）を備えています。製品データはCSV経由でエクスポートされます。ページとカスタムコンテンツは構造化された抽出が必要です。すべてのコンテンツをエクスポートし、Next.jsと Tailwind CSS でデザインシステムを再構築し、大幅に改善されたパフォーマンスで同じビジュアル美学を実装します。
機能するものを保持する
Squaespaceサイトに気に入ったデザインがある場合、私はそれをコード内に忠実に再構築します -- プロセスでそれを改善することが多く、Squaespaceテンプレートの制約が防ぐ方法でレスポンシブにします。

Squarespace vs Next.js
| Metric | Squarespace | Next.js |
|---|---|---|
| Lighthouse (mobile) | 35–60 | 95–100 |

| Monthly cost | $23–$65 | $0–$20 |
| Design flexibility | Template-constrained | Unlimited |
Common questions
Will my Squarespace design be preserved?
I rebuild the design as React components matching your current Squarespace aesthetic. In many cases the rebuilt site looks better because Next.js gives full CSS control without Squarespace template constraints.
What happens to my Squarespace blog?
Squarespace exports blog posts as XML. I import all posts into Supabase or Sanity with metadata, categories, tags, and featured images preserved.
What about Squarespace Commerce?
Squarespace Commerce exports products as CSV. I migrate products to Shopify (if you need managed e-commerce) or to a headless commerce setup with Next.js + Stripe for custom checkout.
Why does Squarespace score badly on Lighthouse?
Squarespace loads the full platform framework on every page — including commerce functionality on pages that are not shops. This adds 300-600KB of JavaScript that cannot be removed. It is not a configuration issue; it is the platform architecture.
Will my SEO improve after migration?
Almost certainly. Moving from Lighthouse 35-60 to 95-100 removes a negative ranking signal. Combined with preserved URL structure and SEO metadata, most clients see ranking improvements within 60-90 days.
