Quick answer
Squarespace is a reasonable starting point for very early-stage businesses that need something live fast. For any business serious about search performance, page speed, and long-term growth, a custom Astro site delivers meaningfully better results — and often lower total cost of ownership once you factor in platform fees.
Every few weeks, a small business owner asks us whether they should stick with their Squarespace site or invest in something custom. It is a reasonable question, and the honest answer is: it depends on what you need your website to do.
This post lays out the real differences — not to talk you into anything, but to help you make an informed call.
What Squarespace gets right
Squarespace is not a bad product. It is genuinely accessible. You can launch a decent-looking site in a weekend without writing a line of code. Templates are polished. The editor is visual. Hosting, SSL, and basic analytics are included. For a very early-stage business that needs something live fast, it clears the bar.
The problems are not in what Squarespace does — they are in what it cannot do as your business grows.
The real-world comparison
| Squarespace | Custom Astro Site | |
|---|---|---|
| Time to first launch | Days (template-based) | Weeks (custom design + build) |
| Page speed | Moderate — bloated JS bundles | Excellent — ships minimal JavaScript by default |
| Core Web Vitals | Often mediocre out of the box | Optimized by design |
| SEO control | Limited — basic title/description only | Full — structured data, canonical tags, sitemap, schema |
| Design flexibility | Constrained by template structure | Unlimited — designed to your brand |
| Ongoing platform cost | Monthly/annual subscription | Hosting only (you control the provider) |
| E-commerce transaction fees | Yes (on lower plans) | None (integrate whatever payment processor you want) |
| Content management | Built-in visual editor | CMS of your choice (Markdown, Decap, Sanity, etc.) |
| Security | Managed by Squarespace | Managed by your host + static site hardening |
| Scalability | Capped by platform limits | No ceiling |
The performance gap is real
Squarespace builds pages using a JavaScript-heavy rendering approach. On a good connection, users may not notice. On mobile, on slower networks, or in markets where Google is actively measuring load performance as a ranking signal, it shows up.
Astro, the framework we build on, ships zero JavaScript by default. Each page is pre-rendered HTML — it loads almost instantly. Interactive components (a contact form, an animated element) get JavaScript only when needed. The result is pages that score well on Core Web Vitals: Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint.
Google uses Core Web Vitals as a ranking signal. A site that loads faster and shifts less is, all else equal, more likely to rank.
The SEO ceiling on Squarespace
Squarespace gives you a title field and a description field. For a simple informational site in an uncompetitive niche, that might be enough. For most small businesses trying to win local search, it is not.
A custom site lets you implement:
- Structured data (JSON-LD) — schema markup for your business, services, articles, and FAQs, which feeds both Google and AI answer engines
- Canonical tags — prevent duplicate content penalties when content appears at multiple URLs
- Custom sitemaps — with priority and change frequency signals
- Open Graph and Twitter card tags — for rich social sharing
- Per-page meta robots — index some pages, noindex others
None of this is possible or flexible in Squarespace. On a custom build, it ships standard.
The total cost question
Squarespace looks cheap until you run the numbers over time. Add up subscription fees across two to three years, plus any transaction fees if you sell anything, plus the opportunity cost of lower search rankings and slower load times.
A custom site has a higher upfront cost and a lower ongoing one. You own the code, you choose your host, and you pay no platform tax. For most businesses that stay in business, the custom route becomes cheaper over a three-year horizon.
When each option makes sense
Choose Squarespace if:
- You need something live in days, not weeks
- Your business is pre-revenue and budget is the primary constraint
- The site is a placeholder while you validate the business model
Choose a custom site if:
- Search traffic matters to how you generate leads
- You want the site to reflect your brand distinctly, not look like a template
- You plan to grow — in services, in pages, in functionality
- You want to own the asset, not rent it

Frequently asked questions
- Can Squarespace rank well in Google?
- Squarespace sites can rank, but they carry structural disadvantages: bloated JavaScript bundles, limited control over technical SEO, and slower load times compared to a well-built custom site. For competitive local searches, those gaps matter.
- Is Squarespace cheaper than a custom site?
- Upfront, usually yes. Over two to three years, it depends. Squarespace has a recurring subscription fee and charges transaction fees on e-commerce. A custom site has a one-time build cost and hosting fees you control. The math changes faster than most people expect.
- What is Astro and why does it matter for performance?
- Astro is a modern web framework that ships zero JavaScript by default — it only sends interactive code when a component actually needs it. The result is very fast pages that score well on Core Web Vitals, which Google uses as a ranking signal.
- When does Squarespace actually make sense?
- If you need something live in a weekend, have no budget for development, and your business is pre-revenue, Squarespace is a pragmatic stopgap. Once the business is generating revenue and you rely on search traffic, a proper custom build pays for itself.
