Is there a free Squarespace SEO checker?

What to do about it

1. Paste the public Squarespace URL into the free WebVitalist scan. No account and no credit card. It reads the page Squarespace already published.
2. Read the title, meta description, and H1 findings first. Those are the SEO fields Squarespace owners can edit in the page settings.
3. Open Settings, then Advanced, then Code Injection only if the scan or a later audit points at scripts in the header. Extra scripts load on every page.
4. Use Google PageSpeed Insights when you want the Core Web Vitals score. Use the Squarespace guide when you want checks written for that platform.
5. Buy a one-time Deep Audit if you want Lighthouse and a prioritized plan. A monthly SEO suite is optional, not required, for one Squarespace site.

What WebVitalist checks

The free scan runs 19 technical checks on one public URL. These are the ones that matter for this question:

• Page title (title): The free scan fails a Squarespace page with no title, and warns when the title is shorter than 30 or longer than 65 characters.
• Meta description (meta-description): The free scan fails a page with no meta description, and warns when it is shorter than 70 or longer than 165 characters.
• Server response time (ttfb): Squarespace controls the hosting, so you cannot change the server. The free scan still records server response time, so you know whether delivery or page weight is the problem.

A paid audit ($9 and up) also runs a real mobile Lighthouse test through Google PageSpeed Insights and reads field data for LCP, INP and CLS, where Google has it.
