Health Scan by SQSMODS Review (2026): A Pre-Launch Checker for Squarespace Sites

Launch day on a Squarespace site is rarely the problem. The problem is the week after, when the client notices the footer still says 2024, a shared link shows no picture, the contact form is sending enquiries to the designer's own inbox, or Google has quietly been told not to index the home page. None of these are hard to fix. They are hard to remember, across dozens of pages, on every single build.

At Design by Altitude we are a Squarespace Platinum Partner with more than 400 client builds behind us, and we have a launch checklist for exactly this reason. Health Scan by SQSMODS is the first tool I have seen that runs most of that checklist for you, in about twenty seconds, and explains every issue in plain English with the exact place in Squarespace to fix it. This is my first-hand look at version 1.0.10. You can also find Health Scan on SquareLocator.

Quick Verdict

Health Scan is a Chrome extension that reads a Squarespace 7.1 site's public pages, blog, events and store, then gives it a health score and a list of issues grouped into SEO, social images, pages and links, forms and email, store, and code. It is strictly read only: nothing on the site is changed. The checks are the ones that actually bite after launch, the explanations are written for humans, and the free plan covers one site. If you build or look after Squarespace sites for clients, it belongs in your launch routine. It is brand new, so expect it to grow, and check the SQS Mods site for current plans before you commit.

A Walkthrough With Its Maker

On 29 October I had a call with Roland van den Hout of SQS Mods, the same developer behind the Code Block Editor. He took me through Health Scan feature by feature, then through every part of the Code Block Editor, including the new Create panel. Roland is a lovely guy and clearly builds what he would want to use himself: the explanations in Health Scan read like a senior designer looking over your shoulder rather than an SEO tool shouting about scores. Both are very good extensions and both are now part of SquareLocator. You can read my updated Code Block Editor 4.0 review alongside this one.

How Health Scan Works

You install the extension in Chrome, open the Squarespace site in a tab and click the Health Scan icon. You can also type any address, including a built-in squarespace.com address, into the scan screen. Before scanning you confirm you own the site or have permission. It reads the home page first, then every page, blog post, event and product it can reach, checks links, styles, schema and files, and returns a score with a full report. Large sites take up to about twenty seconds.

Every issue has a View details panel with three parts: what was found, why it matters, and where to fix it, written as a Squarespace menu path such as Marketing, SEO, Search appearance. That last part is the real time saver. Junior designers and site owners do not need to know where Squarespace hides a setting; the report tells them.

Reports can be printed or saved as a PDF (Letter or A4) and exported as CSV. On the Pro and Agency plans every scan is saved to your account, so you can follow a site's score over time from any computer, including a web dashboard. Sign-in is by emailed code, with no password.

What It Checks

SEO

• Search engines asked not to index the site, a hidden home page, or a site that is not public yet
• Missing or duplicate SEO descriptions on pages, posts, events and products
• Page titles over about 60 characters, or a home page title that is only the site name
• Missing or multiple Heading 1s on a page, and pages with very little text
• Images without alt text, and very large original images
• Schema that is invalid or duplicated
• Leftover home page versions and test pages that are public and in the sitemap
• AI crawlers blocked, and no llms.txt description
• The site still using its built-in squarespace.com address

Social images

• No site-wide social image, and pages, posts or products with no image to share

Pages and links

• Internal links to missing pages, external links that fail, and file links that no longer open
• Anchor links pointing to sections that do not exist
• Buttons and links with no destination
• Template placeholder text and Squarespace demo social links left on the site
• The default Squarespace 404 page, a missing favicon, and an out-of-date footer copyright year
• Pages with the header or footer switched off

Forms and email

• Which email address each form sends to, which catches the classic handover mistake of enquiries still going to the designer

Store and events

• Product prices that look wrong, sale prices that do not make sense, and digital products with no file
• Duplicate SKUs, products with no category, and missing shipping weights where they matter
• Events still using the template's New York address, events with no location, and old events still featured

Tracking and code

• Tracking that runs with no cookie banner, and a pasted Google Analytics tag that fires before consent
• Google Analytics loaded twice
• An inventory of scripts in Code Injection and code blocks, which is a useful handover document in its own right
• HTML comments that look like they hold a key or licence code, files loaded over insecure http, and HSTS switched off
• Custom CSS that will break when a page is rebuilt

Where It Fits in an Agency Workflow

We will be running Health Scan at three points: before a site goes live, at handover so the client gets a clean report, and once a quarter on care plan sites, where content added by the client tends to drift (missing descriptions, huge images, no alt text). The code inventory alone is worth having at handover; I have lost count of the number of sites we inherit with three abandoned tracking scripts nobody can explain.

It is not a replacement for a proper SEO tool such as SEOSpace, which is built for ongoing rankings and content work, and it is not a backup. For that, see our guide on how to back up a Squarespace website. Health Scan is the pre-flight check, and it does that job well.

Plans and Pricing

At launch Health Scan has three plans. Free covers one Squarespace site, but scores are not saved, so there is no score history. Pro is $15 a month for five sites, with every scan saved to your account. Agency is $30 a month for unlimited sites and adds white label reports, with your studio's name and logo on the PDF in place of Health Scan. Plans may change as the product grows, so check the Health Scan page for current pricing.

The Honest Limitations

• Squarespace 7.1 only. Version 7.0 sites are not supported.
• Chrome only. It is a Chrome extension, so Safari and Firefox users need Chrome or another Chromium browser.
• Public pages only. It reads what a visitor can see. Disabled, password-protected and member-only pages are outside its view, which the report is careful to point out.
• It reports, it does not fix. That is deliberate and I would not want it any other way on a client site, but you still make every change yourself.
• It is new. Version 1.0.10 is solid, but expect checks to be added and refined over the coming months.

Who Should Use It

Designers and agencies launching Squarespace sites for clients, anyone taking over a site built by someone else, and site owners who want to know what is quietly wrong with their site before Google or a customer finds it. If you only ever build one site and just want a one-off check, the free plan is enough. If you run a care plan or launch a site a month, the paid plans are where it earns its keep, not least because they keep each site's score history.

Frequently Asked Questions

What is Health Scan by SQSMODS?

Health Scan is a Chrome extension from SQS Mods that checks a Squarespace 7.1 site before launch. It reads the public pages, blog, events and store, gives the site a health score, and lists issues across SEO, social images, links, forms, store and code, each with a plain-English explanation and where to fix it in Squarespace.

Does Health Scan change anything on my site?

No. It is read only. It reads the site's public pages in your browser and never edits content, settings or code.

Is Health Scan free?

There is a free plan that covers one Squarespace site, although it does not save your scores. Pro is $15 a month for five sites with every scan saved, and Agency is $30 a month for unlimited sites with white label reports. Check the SQS Mods site for current pricing.

Does it work on Squarespace 7.0?

No. Health Scan supports Squarespace 7.1 sites only, and tells you if the site you scan runs an older version.

Can I give the report to a client?

Yes. Reports can be printed, saved as a PDF in Letter or A4, or exported as CSV. On the Agency plan the PDF carries your studio's name and logo instead of Health Scan branding.

Does Health Scan replace an SEO tool?

No. It is a launch and health check that catches technical and housekeeping problems. For ongoing keyword, ranking and content work you still want a dedicated SEO tool alongside it.
