Connecting multiple domains to your Squarespace site won't hurt your site's SEO. We prevent search engines from penalizing you for duplicate content by redirecting multiple domains to one primary domain.
With this in mind, having multiple domains is an asset. Creating many domains gives visitors more ways to find you, captures common misspellings, and keeps competitors from registering similar domain names.

We help you stay friendly to search engines by redirecting multiple domains to one domain
When using multiple domains, you'll choose a primary domain that acts as the main address for your site. The primary domain will always appear in the browser address bar no matter which domain a visitor uses. This method allows you to connect multiple domains, which can generate valuable traffic, while preventing search engines from thinking you have duplicate content.
We avoid what's bad for search: mapping multiple domains
In the past, it was common to use multiple domains with important keywords in the URL to increase traffic. Search engines caught onto this tactic and started identifying sites like this as spam.
In more technical terms, this happens when multiple domains, like www.example.com and www.example2.com, are fully mapped to a site. A visitor could visit a page at either www.example.com/about or www.example2.com/about see the same page but with URLs reflecting multiple primary domains.
Squarespace avoids this issue by redirecting multiple domains to a single primary domain.
