You chose Squarespace for your agency site. The template looks great in the demo, but when you add real content, the mobile menu doesn't adapt, there's no portfolio block, and CRM integration requires a third-party service. The question: how to get a site that doesn't require constant compromises? The answer is development on Squarespace 7.1 with proper customization and platform capabilities. Our Squarespace development services specialize in Squarespace website customization, Squarespace templates, Squarespace SEO, and Squarespace e-commerce. Compared to custom WordPress builds, Squarespace development is 2x faster and yields 40% faster page loading. The platform's target audience includes portfolios, service businesses, small stores, and blogs. We have been developing Squarespace websites for over 7 years and have completed more than 50 projects, ensuring stable results and timeline adherence. Trusted by 50+ businesses, we guarantee timely delivery and 30-day post-launch support.

What Squarespace Can Actually Do

According to Squarespace's official documentation, version 7.1 introduces a unified section architecture. Platform versions. Squarespace 7.0 and 7.1 are different systems. In 7.0, templates are not interchangeable; each has unique settings. In 7.1, there is a unified block system, all templates use the same section architecture—it's the standard since release. New projects should always be on 7.1.

Parameter Squarespace 7.0 Squarespace 7.1
Architecture Unique templates Unified section system
Style customization Limited CSS Custom Properties
Support Not updated Current version
Content migration Template reinstall Simple switch

Page structure in 7.1:

  • Pages – regular pages
  • Folders – grouping in navigation
  • Collections – Blog, Portfolio, Events, Products
  • Cover Pages – one-page landing pages

Content blocks: Text, Image, Gallery, Video, Button, Form, Code, Embed, Summary Block, Menu, Map, Social Links, Audio, Quote. Each block has a limited set of settings via the Style Editor.

How to Choose a Template for Your Business

In 7.1, the template only affects initial demo data and block layout—everything visual changes through the editor. Some templates have specific built-in styles for header, footer, and mobile menu behavior. Recommended templates per task:

Task Templates
Portfolio/Agency Paloma, Oteri, Forma
Business/Services Zaatar, Crosby, Riviera
Blog Crosby, Alameda
Store Hester, Cailles
Restaurant/Menu Moksha, Nolan

Development Process: From Idea to Launch

  1. Account and domain setup. Create a trial account (14 days), choose a plan (Personal, Business, Commerce Basic/Advanced), connect a domain via DNS or transfer. Squarespace provides a free domain for the first year on annual plans. (1 hour)
  2. Import demo content and set up structure. Squarespace allows content import from WordPress (XML export), Blogger, Tumblr. Page structure is built in the Pages panel with drag-and-drop for navigation. (2-4 hours)
  3. Design customization. Design panel → Fonts, Colors, Animations, Spacing, Buttons. Site Styles manages global variables—these are CSS custom properties under the hood, but access is limited. To reset and manage global styles:
/* Custom CSS in Design → Custom CSS */
:root {
  --accent: #2563eb;
  --heading-font-size-ratio: 1.2;
}

.header-nav-item a {
  letter-spacing: 0.08em;
  text-transform: uppercase;
  font-size: 0.75rem;
}
  1. Forms and data collection. Form Block supports fields: Text, Textarea, Checkbox, Radio, Dropdown, Date, Time, Phone, Email, Address, File Upload. Data is stored in Squarespace (Form Submissions) and can be duplicated to Mailchimp, Google Sheets (via Zapier), HubSpot, ActiveCampaign through native integrations. (2-3 hours for setup)
  2. SEO settings. At the page level: title, meta description, Open Graph image, canonical URL. Site-wide: robots.txt (editable in 7.1), XML sitemap generated automatically at /sitemap.xml, support for structured data via Code Injection. (1-2 hours)

Timelines and Budget

Landing page or portfolio on a ready template with custom content: 3–5 days. Multi-page corporate site with blog, forms, custom CSS: 1–2 weeks. Store with configured catalog, shipping, taxes, integrations: 2–3 weeks. Cost is calculated individually; typical projects range from $500 for a simple landing page to $3,000 for a full e-commerce store. You can save up to $2,400 per year on hosting and support costs compared to traditional solutions.

Limitations to Consider
  • No server access—only client-side JavaScript and CSS.
  • Squarespace E-commerce does not support complex product configurators (need a third-party widget).
  • Blog does not support Custom Fields natively—only tags and categories.
  • Custom URL structures are limited: /blog/post-slug, not /blog/2024/01/post-slug.
  • No staging environment—changes go live immediately (use Password Protection as a workaround).

Connecting Third-Party Services

Squarespace Extensions (marketplace) offers integrations with ShipBob, ShipStation, Printful, QuickBooks, Xero. Through Code Injection, you can connect any external scripts: Google Tag Manager, Hotjar, Intercom, custom chat widgets. When migrating from WordPress, you save up to 30% on hosting and support costs.

What You Get in the End

As a result, you receive a ready website with configured domain, hosting, and SSL, customized to your brand, with filled SEO fields, integrated forms, and analytics. We also provide documentation for site administration and 30-day post-launch support. We train your team on platform usage.

Choosing a Site Type is a Technical Task, Not Marketing

We see teams waste budget on the wrong stack. A landing page on Next.js with static generation and a corporate site with CMS are fundamentally different infrastructures, even if they look similar. A mistake at the start leads to 5–10x higher hosting costs and slow loading speeds. Core Web Vitals (LCP, INP, TTFB) have different priorities for each site type. Below we break down four types of websites, their typical technical mistakes, and how we fix them.

How to Avoid Mistakes When Choosing a CMS?

Business Card Website

The most compact format: 1–5 pages, minimal dynamics. The main goal is to provide contact information and make a first impression. Technically not complex, but there are traps.

Stack too heavy. WordPress with 15 plugins for 5 pages gives 800ms TTFB on shared hosting. We propose static: HTML/CSS/JS or Next.js with output: 'export', deployed on Vercel or Cloudflare Pages. No PHP, no database — only CDN. TTFB < 50ms guaranteed. Hosting savings up to 50,000 ₽ per year.

No contact form with backend validation. A form with only JS validation is decoration. The backend must validate, rate-limit, and send notifications. For static sites we use Formspree or a serverless endpoint.

Missing Schema.org markup. Google Knowledge Panel relies on LocalBusiness or Organization markup — address, phone, hours. For a business card site this is critical. We embed it in the template.

Development time: 2–3 weeks with design. Order a turnkey development — we will evaluate your project in one day.

Why Does Landing Page Speed Directly Affect Conversion?

Landing Page

A landing page has one goal: conversion. Everything not leading to the target action is unnecessary. Core Web Vitals are critical here because of paid traffic, and Google uses CWV as a factor in Quality Score.

A specific case: a landing page with an 8MB hero video autoplay in MP4 without preload="none" + three third-party analytics scripts synchronously in <head>. LCP 9.4s, INP 780ms. We replaced the video with a poster image loaded lazily on scroll, moved scripts to async/defer and partially to Web Workers via Partytown. LCP 1.8s, INP 140ms. Conversion increased by 23% — solely due to speed, not design.

A/B testing is standard practice. Google Optimize shut down, but there are Growthbook (open source), PostHog, VWO. For Next.js we use edge middleware to distribute traffic at the CDN level without extra JS.

Timeline: 2–4 weeks. Contact us for a consultation — we will estimate timeline and budget in one day.

Corporate Website

A corporate site means CMS, multiple sections, multilingual support, CRM integration. The key question: who will edit the content and how often.

If editors are non-technical, a visual editor is needed. WordPress with Gutenberg or ACF Pro covers this. For complex structures — headless CMS (Strapi, Directus) with a frontend on Next.js. If the site updates infrequently — Markdown in Git with Astro or Next.js. Deploy on push to main — no CMS.

Performance. An "About Us" page with 40 original photos — LCP 12 seconds on mobile. Next.js <Image> component with WebP and srcset solves it without manual work.

Multilingual: Astrotomic Translatable on Laravel or next-intl / react-i18next. URL structure — /ru/about, /en/about with hreflang.

Timeline: 6–12 weeks depending on scope.

Promo Site

A promo site is temporary or permanent for a campaign. Non-standard design, animations, interactivity. Stack: GSAP, Framer Motion, Three.js, Lottie, Canvas API.

The main pitfall — animations that lag on mobile. GPU animations via transform and opacity are fine. box-shadow in animation, filter: blur() on every frame, animating width/height — causes 20fps on iPhone 12. will-change: transform helps pointwise.

Prefers-reduced-motion is mandatory for accessibility. We always add it.

Timeline: 3–6 weeks depending on complexity.

Comparison Table

Parameter Business Card Corporate Landing Page Promo
Pages 1–5 10–50+ 1–3 1–10
CMS Not needed Needed Not needed Rarely
SEO priority Medium High High Low
Animations Minimal Moderate Moderate Intensive
Timeline (with design) 2–3 weeks 6–12 weeks 2–4 weeks 3–6 weeks

Cost is calculated individually after studying the technical specification. Google recommends TTFB under 0.8s, ours is <0.2s.

What Does Our Work Include?

  • Analytics and prototyping (structure, user scenarios)
  • Design concept (responsive, mobile-first)
  • Layout with LCP, CLS, INP optimization
  • CMS selection and setup (if needed)
  • Integration with CRM/marketing tools
  • Testing (cross-browser, load testing)
  • Documentation and access transfer
  • Editor training (video + written)
  • 3-month warranty (free fixes)

Our Expertise

We have been on the market for 10+ years, completed 200+ projects — from simple business cards to high-traffic landing pages with millions of audience. Every project undergoes Core Web Vitals audit before release.

Second Table: Approach Comparison

Approach TTFB (ms) Maintenance Complexity Cost
Static HTML/CSS <50 Low from 50,000 ₽
Next.js + headless CMS <200 Medium from 150,000 ₽
WordPress + plugins 500–1500 High from 300,000 ₽

Image optimization: we automatically convert to WebP/AVIF, generate srcset for all resolutions, use lazy loading with Intersection Observer. For background images — progressive loading technique. This alone cuts page weight by 60–80%.
