The average Squarespace site scores 40.5 out of 100 on SEO audits, and 66.4% are missing alt text on images — the platform’s single biggest recurring gap. That’s not a reason to panic if you’re on Squarespace already. It’s a reason to know exactly which of its limitations you can work around and which ones you genuinely can’t.
The 40.5 average score is a blended figure covering a huge range of individual sites, and it’s worth being clear that the number reflects widespread underconfiguration of fixable settings, not an inherent platform ceiling of 40.5. A Squarespace site that’s had its alt text, headings, meta descriptions, and available schema options genuinely attended to routinely scores well above that average — the gap between the average site and a well-optimized site on the same platform is almost entirely attributable to attention, not platform capability. That distinction matters for how a business should read this statistic: it’s not evidence that Squarespace caps SEO performance at a mediocre level, it’s evidence that most site owners never do the fixable work the platform actually allows.
What Squarespace Actually Gets Right
Give the platform credit where it’s earned: about 70% of Squarespace sites post good Core Web Vitals scores, compared to roughly 50% across all platforms combined — the hosting and templates are genuinely fast out of the box, which is more than can be said for a lot of poorly-configured WordPress installs. If your business runs on Squarespace for design or ease-of-use reasons, you’re not starting from a performance deficit.
This performance advantage is worth understanding structurally rather than treating as a simple platform quality claim, because it stems from a genuine architectural trade-off, not luck. Squarespace controls the entire hosting environment, template code, and image delivery pipeline for every site on the platform, which means the average site benefits from performance optimizations the company has already built in at the infrastructure level — image compression and responsive delivery happen largely automatically, without requiring the site owner to configure a caching plugin or a CDN themselves. WordPress’s flexibility is precisely what removes this guardrail: a WordPress site’s actual performance depends entirely on the hosting provider chosen, the plugins installed, and how carefully the whole stack is configured, which is why WordPress sites show far more variance in Core Web Vitals scores than Squarespace sites do. Squarespace trades away configurability for a performance floor most site owners couldn’t reliably achieve on their own without real technical expertise — a trade a lot of small businesses reasonably make. That said, a fast template is only part of the picture; how a site is actually laid out on top of it still matters, which is covered in our guide to how website design affects SEO.
Squarespace’s SEO Report Card
The average Squarespace site scores 40.5 out of 100 on SEO audits, with 66.4% missing image alt text, but about 70% post good Core Web Vitals scores compared to roughly 50% across all platforms.
Try It: Should You Stay on Squarespace?
Stay on Squarespace. Fixing alt text, headings, and meta descriptions closes most of the practical gap. Migration would cost more than the ranking benefit for this competition level.
Stay, but fix fundamentals rigorously. The platform’s Core Web Vitals advantage helps here — pair it with disciplined alt text, structured headings, and manual schema workarounds to compete.
Consider migrating. Missing native schema automation, canonical control, and server-level access become real ceilings once every technical edge counts at this competition level.
Interactive tool: local service businesses with low competition should stay on Squarespace, moderate-competition niches should stay but rigorously fix fundamentals, and high-difficulty national or international competition should consider migrating.
Where the Platform Genuinely Blocks You
No native schema markup automation, no server-level access for caching or redirect rules, no manual control over canonical tags or robots.txt beyond what Squarespace’s interface exposes, and a fraction of the third-party SEO plugin ecosystem WordPress has. The blogging tools are basic — no internal linking suggestions, no content clustering support — which matters more than it sounds, since internal linking is one of the more reliable levers for topical authority we cover in our semantic SEO guide.
The internal linking limitation deserves particular attention because it compounds silently over time in a way the more visible gaps, like missing alt text, don’t. A business publishing blog content on Squarespace without a deliberate manual internal linking discipline will, almost by default, end up with a collection of isolated posts that never build into the kind of interconnected topic cluster that produces durable topical authority — not because Squarespace actively prevents good internal linking, but because it offers none of the prompts, suggestions, or structural tools that make good linking the path of least resistance the way some WordPress plugins do. This is entirely fixable through manual discipline — deliberately linking new posts back to relevant existing content and updating older posts to link forward to new related pieces — but it requires the site owner or content team to build that habit themselves rather than relying on the platform to nudge them toward it, which is exactly the kind of quietly-missed opportunity an outside audit tends to catch that a business managing its own content might not notice for months or years.
| Capability | Squarespace | WordPress (well-configured) |
|---|---|---|
| Out-of-box Core Web Vitals | Strong (~70% pass) | Variable — depends heavily on hosting and plugin choices |
| Schema markup automation | None native | Extensive via plugins (Yoast, RankMath, etc.) |
| Server-level access (caching, redirects) | None | Full access |
| Canonical tag / robots.txt control | Limited to platform interface | Full manual control |
| Internal linking / content clustering tools | Basic, manual only | Extensive via plugins and manual structuring |
| Ease of setup and maintenance | High — minimal technical skill required | Lower — requires ongoing technical maintenance |
The Honest Trade-Off
Squarespace is a reasonable platform for moderate-competition niches and businesses that need something up quickly without managing a CMS. It becomes a real ceiling once you’re competing for high-difficulty terms where every technical edge counts — structured data, custom redirects, and granular crawl control start to matter, and those are exactly the levers Squarespace locks away. We don’t reflexively tell every Squarespace client to migrate; for many local service businesses, the fixable issues (alt text, headings, basic meta) close most of the gap without a platform change.
Closing the Alt Text Gap: The Highest-Leverage Fix
The 66.4% missing-alt-text statistic represents the single largest, cheapest fix available to most Squarespace site owners, and it’s worth understanding why this specific gap is so widespread before dismissing it as a minor detail. Squarespace’s image upload interface doesn’t force an alt text field the way some platforms do, and it’s easy to publish an entire gallery or product catalog without ever being prompted to add descriptive text — the platform makes the correct behavior possible but not the default, and most site owners simply never discover the setting exists until an audit flags it. Alt text serves two functions that both matter for SEO: it gives search engines textual context about image content they can’t otherwise interpret, and it’s a genuine accessibility requirement for screen reader users, meaning fixing it addresses both a ranking factor and a real usability gap simultaneously. For a typical small business site with fifty to two hundred images, a dedicated afternoon working through the media library and writing genuine, descriptive alt text for each image is realistic, and the SEO and accessibility improvement from that single afternoon of work often exceeds what a much larger, more expensive intervention elsewhere on the site would produce.
Working Around the Schema Limitation
The lack of native schema markup automation is a genuine limitation, but it isn’t an absolute wall the way server-level access restrictions are. Squarespace allows custom code injection through its header and footer code injection fields on Business-tier plans and above, which means manually-written JSON-LD schema markup can be added to specific pages even without a native plugin ecosystem to automate it. This requires more manual, ongoing maintenance than a WordPress plugin that auto-generates schema from existing page content — every new page needing schema requires manually writing and inserting the appropriate markup — but it’s a genuinely viable workaround for a business with a manageable number of key pages needing structured data (a handful of core service pages, an FAQ page, a local business listing), rather than the hundreds of pages where manual schema maintenance would become impractical. Businesses considering a platform migration purely to solve the schema gap should weigh this manual workaround first, since it may close a meaningful part of that specific gap without the cost and disruption of a full platform change.
A Worked Example: Fixing Fundamentals Without Migrating
A Swiss boutique retail client came to us convinced their Squarespace site needed a full migration to WordPress to fix persistently weak organic visibility. A full audit found the actual issues were almost entirely in the fixable category: 80% of product images missing alt text, heading structure that skipped levels inconsistently across product pages, and meta descriptions either missing entirely or auto-generated from the first sentence of body copy rather than written deliberately. We spent three weeks working through the alt text backlog, standardizing heading structure across templates, writing genuine meta descriptions for every indexed page, and manually adding JSON-LD product schema via code injection to the twenty highest-traffic product pages. Organic traffic rose 31% over the following four months with zero platform change and a considerably smaller cost than a full WordPress migration and redesign would have required. This doesn’t mean migration is never warranted — for a business genuinely competing on high-difficulty national terms, the platform ceiling described elsewhere in this piece is real — but for the large majority of Squarespace clients we’ve audited, the actual bottleneck was fixable fundamentals, not the platform itself.
When Migration Actually Makes Sense
Migration becomes the right call when a business has already closed the fixable gaps — alt text, headings, meta descriptions, basic schema via code injection — and is still hitting a ceiling specifically traceable to a platform limitation with no workaround, such as needing genuinely dynamic, database-driven content structures Squarespace’s page-based model can’t support, or needing server-level redirect and caching control for a large, complex site. Migration is expensive and disruptive: URL structures typically change, requiring careful redirect mapping to preserve existing rankings during the transition, and the migration period itself carries real risk of a temporary visibility dip if not executed carefully. That cost is worth paying when the platform ceiling is the genuine bottleneck to further growth. It’s not worth paying as a first response to disappointing SEO results before ruling out the much cheaper, much faster fundamentals-first fix that resolves the issue for most businesses we’ve actually audited.
Multilingual Swiss Sites on Squarespace: An Additional Constraint
A Swiss business running a multilingual site on Squarespace faces a constraint worth flagging separately from the general limitations above: the platform’s native multilingual support, while functional for basic cases, doesn’t offer the granular hreflang control a genuinely well-built German/French/Italian site benefits from — the kind of tag-level precision covered in our international SEO guide. Squarespace’s language and region settings handle the basics reasonably well for straightforward cases, but a business with more complex regional targeting needs (differentiating de-CH from de-DE content, for instance) will find the platform’s built-in tools less flexible than a properly configured WordPress multilingual plugin setup. For a Swiss business whose multilingual coverage is central to its SEO strategy rather than a secondary consideration, this is one of the more concrete scenarios where the platform’s general limitations translate into a specific, measurable competitive disadvantage worth weighing seriously against the ease-of-use benefits that make Squarespace attractive in the first place.

Frequently Asked Questions
Is Squarespace bad for SEO?
Not inherently — it handles page speed and Core Web Vitals well. It becomes limiting for advanced technical SEO like custom schema, canonical control, and content clustering, which matter more in highly competitive niches.
Should I migrate off Squarespace for better SEO?
Usually not necessary for moderate-competition local terms — fixing common gaps like missing alt text and thin meta descriptions closes most of the difference. Migration becomes worth considering mainly for high-difficulty, highly technical SEO plays.
Can I add schema markup to a Squarespace site?
Yes, manually — Business-tier plans and above allow code injection, so JSON-LD schema can be added by hand to key pages even without native automation. It requires more manual maintenance than a WordPress plugin.
What should I fix before considering a platform migration?
Alt text, heading structure, meta descriptions, and manually-added schema on top pages. These fixable gaps resolve most SEO underperformance for the majority of Squarespace sites we’ve audited.
