Fundamentals, definitions and simple scenarios. Good for freshers and warm-ups.
Squarespace is an all-in-one hosted website builder with designer templates, hosting, domains, e-commerce, scheduling and email marketing in one subscription.
It is popular with photographers, designers, restaurants, consultants and small shops who want a beautiful site without managing plugins or servers.
It offers less flexibility than WordPress but is easier and more consistent.
In 7.0 each template had its own features and styles, and switching templates could change functionality.
In 7.1 all templates share the same features and a common section-based editor, so any design can be changed freely through site styles.
New sites are built on 7.1, which also added the Fluid Engine layout editor for drag-and-drop placement of blocks.
A page is built from sections, which are horizontal bands such as a hero banner, gallery or contact area.
Inside each section, blocks hold the content: text, images, buttons, forms, video, products, code and more.
Squarespace offers pre-designed section layouts that can be customised with site-wide styles for fonts, colours and spacing.
In Squarespace 7.1 all templates share the same features, so the choice is only about the starting design and layout.
Choose one close to the content and style you need, such as a portfolio, shop or restaurant layout, then adapt fonts, colours and sections.
You can change the design freely later through site styles.
Layout pages hold sections and blocks for content such as Home, About and Contact.
Collection pages manage repeated items: blog posts, store products, events, portfolio projects and videos, each with its own item page and settings.
Collection items can be shown elsewhere with summary blocks.
The Pages panel controls the main navigation, footer navigation and "Not Linked" pages that exist but do not appear in menus.
Dropdown folders group pages under one menu item, and links can point to external sites or files.
Each page can be enabled, disabled or password-protected.
Form blocks collect information such as enquiries or registrations, with chosen fields and storage options: email notifications, Google Drive, Mailchimp or Squarespace Email Campaigns.
Newsletter blocks collect email sign-ups for mailing lists.
CAPTCHA protection and clear consent text help reduce spam and support privacy compliance.
Plans range from Personal for simple sites to Business and Commerce plans that add e-commerce features, lower or no transaction fees, advanced analytics, code injection and commerce APIs.
Higher commerce plans add features such as abandoned cart recovery, subscriptions and advanced shipping.
Plans are billed monthly or annually.
Squarespace sites are responsive by default.
With Fluid Engine, you can switch to the mobile view and adjust the position and size of blocks for mobile separately without affecting desktop, and hide some elements on mobile.
Text sizes and spacing should be checked on real phones before publishing.
Built-in analytics show traffic, traffic sources, popular content, search keywords, geography, sales, conversion funnels, abandoned carts and purchases by product. You can also connect Google Analytics 4 and marketing pixels, and Google Search Console for detailed search data.
Squarespace Scheduling, built on Acuity, lets service businesses take appointments online.
You set appointment types, availability, prices and intake forms, accept payments and deposits, sync calendars, and send automatic confirmations and reminders.
It can be embedded on the Squarespace site or used on its own scheduling page.
Applied problems, trade-offs and questions about your own projects.
I add a Store page, create physical, digital, service or gift card products with variants, prices and stock, and organise them into categories.
I connect payments through Stripe or PayPal, set up shipping options and tax, and customise the checkout and email notifications.
Squarespace Commerce plans add features such as abandoned cart recovery and subscriptions.
I set the site title and description, then a unique SEO title, description and URL slug for each page and product.
I use proper headings, alt text and image file names, connect Google Search Console and submit the automatically generated sitemap.
I set up 301 redirects in URL Mappings when URLs change and keep pages fast by compressing images.
Custom CSS in the Design panel overrides styles across the site, using selectors for blocks, sections or a specific block ID.
Code injection, available on Business plans and higher, adds code to the header or footer of every page or a single page, such as analytics tags, chat widgets or custom scripts.
I keep custom code small and documented because template updates can affect it.
You can buy a domain through Squarespace or connect one from another registrar by updating DNS records (CNAME and A records) or transferring it.
Squarespace does not host email itself, so professional email is set up through Google Workspace, often integrated, by adding MX records.
I check that SSL is active once the domain connects.
Email Campaigns is Squarespace's email marketing tool.
You build newsletters with templates that match the site's branding, pull in blog posts or products, manage mailing lists and segments, and set up automations such as welcome emails and abandoned cart reminders.
Reports show opens and clicks.
It is billed separately based on volume.
Squarespace lets you sell digital downloads, and member areas (Digital Products) create gated content behind free or paid memberships, such as online courses, premium articles or video libraries. Members sign up and pay through the site, and content is restricted to the relevant member area.
Add a blog collection page, write posts with the editor, add categories and tags, schedule publishing, enable comments and set author profiles.
Each post has SEO settings for title, description and URL slug.
The blog feed creates an RSS feed, which can also distribute podcasts to directories such as Apple Podcasts.
Site styles set fonts, colours, buttons, spacing and animations globally.
Colour themes define palettes that individual sections use, so changing a theme updates every section using it.
Keeping changes in site styles rather than styling individual blocks keeps the design consistent and easy to update.
Fluid Engine is Squarespace's grid-based drag-and-drop editor for sections in 7.1.
Blocks snap to a grid and can be placed, layered and resized freely, with a separate mobile layout.
It gives far more layout flexibility than the older Classic Editor while keeping designs responsive.
Upload images around 1500 to 2500 pixels wide, compressed, under the size limit, and in JPG, PNG or WebP.
Squarespace generates several sizes automatically and serves the right one for each screen.
Set focal points so important parts stay visible when images are cropped, and add descriptive alt text and file names for SEO and accessibility.
Use headings in order, add alt text to images, choose colour themes with enough contrast, use descriptive link and button text, label form fields, avoid essential text inside images, provide captions for videos and check navigation with a keyboard. Squarespace templates handle much of the base markup, but content choices determine most accessibility.
System design, deep internals, leadership and tough follow-ups.
There is no plugin system like WordPress, server-side code is not allowed, the number of products and variants and customisation of checkout are limited, and sites cannot be fully exported, only partially (pages and blog posts to WordPress format).
Very large catalogues or complex custom features are better on other platforms.
For a typical small business site, these limits rarely matter.
Built-in integrations cover Google Analytics, Mailchimp, Google Workspace, social accounts and some shipping and accounting tools.
Form submissions can go to Google Sheets or Mailchimp.
For other systems I use Zapier or Make, embed third-party widgets through code blocks, or use the Commerce APIs for inventory, orders and products on supported plans.
I test it with PageSpeed Insights.
Common causes are large uncompressed images, background videos, many fonts, heavy galleries, and third-party scripts added through code injection.
I resize and compress images before uploading, replace video backgrounds with images on mobile, remove unused scripts and limit animations, then re-test.
Custom code through code injection or code blocks can add features Squarespace lacks, such as advanced filters or animations, and third-party plugins exist.
But it can break when Squarespace updates its templates, may slow the site, is not supported by Squarespace, and is harder for clients to maintain.
I keep custom code minimal, documented and tested after updates.
Squarespace exports only some content, mainly blog posts and pages in a WordPress-compatible XML format, plus products as CSV; designs, galleries and many blocks do not export. So migration means rebuilding the design on the new platform, importing what can be exported, moving images and remaining content manually, and setting up 301 redirects from every old URL.
Squarespace Circle is a programme for designers and developers that offers extended trials, discounts and tools for managing many sites.
Professionals build sites, add clients as owners or contributors with the right permissions, transfer ownership and billing, and keep access for support.
Clear handover guides help clients edit content safely.
Squarespace generates the sitemap, canonical tags, clean URLs and basic structured data automatically. Beyond that, set unique SEO titles and descriptions per page and item, use URL Mappings for 301 redirects, add extra structured data through code injection, optimise image sizes and page speed, build internal links, and use Search Console to monitor indexing and queries.
When the business needs features Squarespace cannot provide well: very large catalogues or complex product options, custom checkout logic, multi-vendor marketplaces, deep integrations with ERPs, complex membership logic, or full control over code and hosting. Shopify suits growing e-commerce, WordPress suits complex content and custom functionality, and Webflow suits design-heavy marketing sites.
