How to Migrate from Squarespace to Aveiro

Move your Squarespace site, blog, email list, and custom domain to Aveiro without losing SEO signals — inventory exports, rebuild pages, import subscribers, set redirects, and launch on one connected publishing stack.

Updated 1mo ago

In short

Audit Squarespace URLs and exports first. Recreate site structure in Aveiro, migrate content page by page, import subscribers via CSV, connect your custom domain for 301 redirects from the old host, then publish with fresh SEO metadata and analytics consent before you cut traffic over.

Why teams leave Squarespace for Aveiro

Squarespace is strong at polished templates and fast launches. Many creators outgrow it when email, analytics, and the site live in separate products — or when Squarespace Email Campaigns, forms, and blog SEO need manual glue work to stay aligned. Aveiro is built for connected publishing: one organization dashboard for sites, audience email, and analytics. That matters during migration because you are not just moving pages — you are often moving subscribers, campaign history habits, and measurement at the same time. Common reasons teams switch:

Squarespace pain	What Aveiro changes
Site forms and email lists do not share one workspace	Signup components write directly to Audience lists campaigns use
Blog + landing pages + newsletter need separate tools	Sites, campaigns, and analytics under one org
Limited control over MDX-style content and AI-assisted edits	Visual editor plus AI that edits existing layouts, not blank-page guesses
Analytics lives outside the site builder	Cookieless, banner-free tracking toggled in site settings
Scaling to docs, collections, or multi-site brands	Collections, file tree, and multiple sites per organization

This guide is a practical migration playbook — not a one-click importer. Squarespace does not expose a full site export Aveiro can ingest automatically. The steps below minimize downtime, preserve URLs where possible, and keep SEO signals intact.

Before you start: migration inventory

Spend one session documenting what you are moving. Future-you will thank present-you when DNS cutover day arrives.

Asset	Where to find it in Squarespace	Aveiro destination
Live pages and blog posts	Pages panel + blog collection	Aveiro Pages file tree (MDX pages)
Images and media	Asset library / page blocks	Re-upload or hotlink during rebuild; prefer upload for long-term control
Custom domain	Settings → Domains	Settings → Site → Custom domain
Email subscribers	Email Campaigns → Subscribers (export CSV)	Audience → Overview → Import subscribers
SEO titles and descriptions	Page SEO settings per page	Page settings + Settings → SEO defaults
URL slugs	Page settings → URL slug	Match slugs in Aveiro page paths before go-live
Forms and CTAs	Form blocks, button links	Email Signup components + named analytics events

Export what Squarespace allows

Blog posts: use Squarespace’s export tools or copy content manually into Aveiro pages. Expect to rebuild layout blocks — Aveiro uses MDX components, not Squarespace sections.
Subscribers: export your Email Campaigns list as CSV (email, optional name columns). See Import subscribers.
Commerce: if you run Squarespace Commerce, plan product pages separately — Aveiro integrates merch via Fourthwall rather than a native cart clone.

Keep a spreadsheet of old URL → new URL for every indexed page. Identical slugs on your custom domain make redirects straightforward after DNS moves.

Phase 1 — Create your Aveiro site skeleton

Do not paste every paragraph on day one. Structure first, content second — the same pattern Aveiro docs recommend for large migrations.

Sign up and complete onboarding at aveiro.app.
Create a new site from a template close to your Squarespace layout (portfolio, marketing, or blog-first).
Open the Pages panel and mirror Squarespace’s information architecture:
- Homepage → index.mdx
- Top-level pages at root (/about.mdx, /contact.mdx)
- Blog posts in a Blog collection (/blog/your-post-slug.mdx)
Rename slugs to match Squarespace paths wherever you want URL continuity (e.g. /blog/my-post stays /blog/my-post).
Publish nothing yet — work on preview until content is ready.

Template help: Choosing a template and File tree and collections.

Phase 2 — Move content page by page

Squarespace content will not transfer as a single ZIP. Treat each page as a small rebuild project. Homepage and marketing pages

Open the Squarespace page and the matching Aveiro page side by side.
Recreate sections using Aveiro catalog components (hero, columns, media, CTAs).
Set title, summary, and cover image in Page settings — these drive SEO and social previews.
Replace Squarespace form blocks with Email Signup components tied to your site list.

Blog posts

Create one MDX page per post inside your Blog collection.
Match the slug to the Squarespace post URL.
Paste body copy; re-add headings, images, and pull quotes with MDX components.
Set publishedAt metadata if your theme or archive pages use it.

Images

Download originals from Squarespace when possible — re-upload into Aveiro for stable URLs and alt text control.
Write descriptive alt text on every hero and inline image (accessibility + image search).

AI-assisted speed-up Use Aveiro’s AI editor to refine copy or adjust layout on the page you already built — paste a section, ask for tighter headlines, or reorder blocks. Avoid generating entire sites from scratch during migration; you already have proven Squarespace content to migrate. Guide: Edit your website with AI without breaking layout.

Phase 3 — SEO: protect rankings during the move

Search engines care about consistent URLs, metadata, and redirects — not which builder rendered the HTML. Match URLs on your custom domain When your custom domain connects to Aveiro, paths like /about and /blog/post-slug should resolve the same as on Squarespace. Slug parity avoids unnecessary 404s on day one. Set site-wide SEO defaults In Settings → SEO and social sharing, configure:

Default site title suffix
Fallback social image
Privacy policy page (disclose analytics there — Aveiro tracking is cookieless, so no banner is shown)

Per-page unique titles beat one generic site title on every URL. Reference: SEO and social sharing. Redirects from Squarespace While Squarespace still serves traffic:

If Squarespace lets you add URL redirects for changed slugs, configure them before cutover.
After DNS points to Aveiro, your *.aveiro.page preview slug 301-redirects to the custom domain automatically when connected — old Squarespace hostnames stop receiving traffic once DNS propagates.

Analytics baseline Enable Aveiro analytics after your privacy policy mentions it. Compare post-migration traffic in Analytics → Overview once the domain serves Aveiro — do not expect historical Squarespace stats to import. See Analytics and privacy. GEO note for AI search Structure pages with a clear In short summary, descriptive H2 sections, tables, and FAQ blocks (like this post). Answer-first paragraphs help both Google featured snippets and AI assistants cite your migration steps accurately.

Phase 4 — Migrate email subscribers

If Squarespace Email Campaigns holds your list, export and import before you announce the new site.

Export subscribers from Squarespace as CSV (email, optional name).
In Aveiro, open Audience → Overview → Import subscribers.
Choose the site list these readers belong to.
Optionally assign a segment (e.g. migrated-squarespace).
Leave welcome email off for cold historical imports — you do not want to surprise years-old contacts. Send a dedicated re-introduction campaign instead once your sending domain is verified.

Import details: Subscribers. Verify a sending domain before the first campaign

Go to Audience → Domains and add the domain you send from (often mail.yourbrand.com or your root domain).
Add SPF, DKIM, and DMARC at your DNS host.
Wait for verification, then send a small test campaign to engaged readers.

Sending setup: Sending domains. Deliverability monitoring: Deliverability. Re-permission if your list is old If Squarespace consent copy promised something different from what you send now, consider a confirm subscription campaign before bulk mail. This protects reputation and aligns with CAN-SPAM and GDPR expectations.

Phase 5 — Connect your custom domain

Cutover is a DNS change, not a content publish button.

Finish rebuilding critical pages on Aveiro preview.
Open Settings → Site → Custom domain and enter your hostname (www.yourbrand.com or apex).
Copy DNS records to your registrar (Cloudflare, Namecheap, Google Domains, etc.).
Click Refresh and check DNS until status shows Connected.
Publish Site settings so SSL provisions and the live domain serves published content.
Confirm https://your-slug.aveiro.page redirects to your custom domain with the same path.

Phase 6 — Launch checklist

Run this list the evening before and the morning of go-live.

Check	Pass criteria
Homepage published	Public URL loads without preview token
Top blog posts published	Each has title, summary, and slug match
Signup form live	Test submission appears in Audience → Overview
Sending domain verified	SPF/DKIM/DMARC green in Domains panel
Subscribers imported	Counts match Squarespace export ± duplicates skipped
Custom domain connected	HTTPS works; slug URL redirects
Analytics	Tracking on; visits appear in Analytics → Overview
CTA events named	Primary buttons fire events in Analytics → Events
Squarespace billing	Cancel or downgrade after traffic confirms on Aveiro

Send one “We moved” campaign with your new site URL and a reminder of why readers subscribed. Link to your privacy policy and include an unsubscribe link — standard, but easy to forget during migration adrenaline.

Squarespace vs Aveiro: what maps where

Squarespace feature	Aveiro equivalent

Email Campaigns	Audience → Campaigns + Automation welcome emails
Form blocks	Email Signup components or embed forms
Built-in analytics	Analytics → Overview, Events, Live
Member areas	Visitor login (see product updates for latest scope)
Acuity / scheduling blocks	Link out or embed third-party scheduling
Commerce	Fourthwall store integration for merch; no native Squarespace Commerce import

Common migration mistakes

Publishing before DNS is ready Visitors hit a half-finished site or old Squarespace pages depending on propagation order. Keep Squarespace live until Aveiro domain status is Connected and key pages are published. Importing subscribers with welcome email enabled Historical Squarespace exports should not trigger welcome automations. Turn welcome off on import; send a manual re-intro campaign instead. Changing every URL slug “while we’re at it” Slug changes without redirects burn inbound links and newsletter deep links. Keep slugs stable unless you configure redirects. Skipping alt text and summaries during rush Migration weeks compress metadata work. Empty summaries hurt social shares and AI-generated search answers — fill them as you publish each page. Ignoring deliverability before a big announcement A migration announcement to a stale list spikes bounces. Verify DNS authentication and watch Deliverability after the first send.

FAQ

Can I automatically import my entire Squarespace site? No. Aveiro does not offer a one-click Squarespace importer. Plan a structured rebuild using templates, collections, and optional AI editing on existing pages. Will I lose my Google rankings? Not if URLs stay consistent on the same domain, pages return 200 responses, and metadata is set. Rankings may fluctuate briefly after any platform change — monitor Search Console for crawl errors. How long does migration take? A five-page marketing site might take a weekend. A 50-post blog with custom forms and a 10k-subscriber list might take two to four weeks part-time. Structure-first workflow saves time. Can I keep Squarespace running during migration? Yes — build on Aveiro preview, then switch DNS when ready. Avoid duplicate content on two public domains long term; pick one canonical host. What about Squarespace scheduling or client portals? Re-create scheduling with external tools and links. Check latest Aveiro docs for visitor login and messaging if you need gated content. Do I need to migrate old campaign analytics? Campaign stats do not import from Squarespace. Export reports for your records if needed; start fresh deliverability monitoring in Aveiro. Can I embed Aveiro signup forms on Squarespace during a gradual move? Yes — use embed forms to collect subscribers into Aveiro while Squarespace still serves pages. Guide: Embed a signup form on any site.
