Squarespace SEO Checklist: What You Can and Cannot Control
Squarespace handles most technical SEO for you and takes several decisions out of your hands. Knowing which is which saves a lot of wasted effort.
Run a fresh DomainLens audit and use the report as your priority list.
What the platform handles for you
Squarespace ships HTTPS, a generated sitemap, mobile-responsive templates, clean URL structures and automatic canonical tags. A large share of a generic technical checklist is satisfied before you open the settings.
It also renders content server-side, so the JavaScript rendering problems that plague custom builds do not apply. That removes an entire category of failure.
The settings worth checking
The title format is the most commonly missed. A site name appended to every page pushes the distinguishing part of long titles past the truncation point in search results.
- 1Set the SEO title and description per page under each page's SEO panel, not just the page title used in navigation.
- 2Check the site-wide title format — the default appends the site name to every page, which eats characters on long titles.
- 3Confirm the primary domain is set correctly, so the other variants redirect rather than resolving in parallel.
- 4Disable the built-in "SEO description" fallback if it produces identical descriptions across pages.
- 5Review image alt text, which Squarespace takes from the filename unless you set it.
- 6Check the blog URL structure before publishing; changing it later renames every post.
The limits you cannot work around
The robots.txt limitation matters less than it sounds, because page-level noindex is the better tool for keeping pages out of search anyway. See noindex vs robots.txt for why.
| Limitation | Impact | Workaround |
|---|---|---|
| No robots.txt editing on most plans | Cannot block specific paths | Use page-level noindex |
| URL slugs fixed by collection type | /blog/, /shop/ prefixes | Plan structure around them |
| Limited server-side control | No custom headers or redirects logic | Use the built-in redirect tool |
| Sitemap not configurable | Cannot exclude URLs | noindex what you want out |
| Injected code runs client-side | Structured data may render late | Prefer native fields |
Where Squarespace sites usually lose
Performance is the recurring one. Squarespace templates are designed to look good, and the default image handling on a photography-led design routinely produces a multi-megabyte hero.
- Image-heavy templates that ship large uncompressed images, failing LCP on mobile.
- Pages built entirely from gallery and image blocks, with almost no indexable text.
- Duplicate descriptions where the site-wide fallback was never overridden.
- Blog posts published without an SEO title, so the H1 doubles as the title tag.
- Third-party code injections adding weight and occasionally conflicting structured data.
How DomainLens contributes
DomainLens reports the titles, descriptions, headings, image handling and Core Web Vitals a Squarespace page actually serves, which is how a site-wide fallback producing duplicate descriptions gets caught. For the metric that most often fails on image-led templates see what LCP measures , and for the platform-agnostic list see the on-page checklist .
- Is Squarespace good for SEO?
- It handles the technical basics well and limits low-level control. For most sites that trade is favourable — the constraints rarely bind, and the defaults are sound.
- Can I edit robots.txt on Squarespace?
- Not on most plans. Use page-level noindex instead, which is the better mechanism for keeping pages out of search regardless of platform.
- Can I change Squarespace URL structure?
- You control the slug, not the collection prefix. Blog posts live under the blog collection path, so plan the structure before publishing.
- Why is my Squarespace site slow?
- Almost always images. Template designs favour large photography, and the defaults do not compress aggressively enough for mobile.
