Add from the Chrome Web Store

It is free. Add it from the Chrome Web Store and it works immediately, with no sign-up. Brave, Vivaldi, Arc and Opera install from the Chrome Web Store too.

How to use it

  1. 1 Add the extension Press “Add to Chrome” in the Chrome Web Store. Permissions cover activeTab, storage, scripting and access to platform.supasaito.com. Access to your own brand domains is requested separately after sign-in.
  2. 2 Click the icon on the page you care about Your page or a competitor’s, it makes no difference. Click the Supasaito icon in the toolbar and choose “Check this page”.
  3. 3 Read the verdict right there A panel opens with a quick score and up to 24 applicable checks, worst first. Expand a row to read its explanation.
  4. 4 Sign in to overlay your own data Sign in and allow your brand’s domains, and on those domains simply opening a page shows SSPS, AI citations and the recommendations for it.

What it does without an account

The page checks run inside your browser without uploading page content. The popup separately contacts the platform to check whether you are signed in.

  • Metadata, canonical and indexability declarations, headings, structured data, author and freshness signals, sharing tags, image alt attributes and mixed-content references: up to 24 checks, where applicable.
  • The quick score uses the product’s own formula and weights. Because its evidence is limited to the HTML, it is deliberately never called SSPS.
  • You can check your own pages or a competitor’s. These markup checks do not establish that every declaration is correct or that an AI assistant has accessed the page.

If you already have an account — the deep audit, on the spot

On allowed brand domains, the connected panel shows available saved audit data for the current URL. Opening it does not launch a new audit or AI scan; results can be cached for up to five minutes.

  • Available standard and deep checks with their priorities. Missing deep results do not mean a measured zero; their availability depends on the audits already run.
  • The SupaSaito Page Score (SSPS) for that URL, the issue count (total and high priority) and the link-health summary.
  • How many times AI assistants cited the page, and when the data was last fetched.
  • A limited selection of open or in-progress technical recommendations for the page. “Open the full report” opens its page audit in the app, not a PDF.
  • On the Free plan you see the snapshot from your first audit (Free has no re-scan).

The 24 checks

The local checks share names with the dashboard. Their scope is narrower: the browser has no full-site crawl or saved classification, so applicability and evidence can differ from the platform audit.

Core meta and indexability

  • Title tag
  • Meta description
  • Canonical
  • Indexable
  • HTML lang
  • hreflang
  • Viewport (mobile)
  • Charset declared

Headings and document structure

  • Single H1
  • Heading hierarchy
  • Semantic HTML5

Structured data

  • Structured data
  • Schema type matches page
  • Breadcrumb

Trust and freshness (E-E-A-T)

  • Author & E-E-A-T
  • Freshness
  • Year in title / H1

Sharing preview (Open Graph / Twitter Card)

  • og:title / description
  • og:image present
  • og:type / og:url
  • OG language match
  • Twitter Card

Other quality signals

  • Image alt coverage
  • No mixed content

Checks that do not apply are dropped from the list and from the denominator. A single-language site having no hreflang is not a defect.

What a local check cannot see

The local checks inspect the current page document. The platform’s saved audits and AI measurements provide other evidence, within their own coverage and dates.

  • HTTP response status and headers, robots.txt, llms.txt, sitemap coverage and destination link health.
  • A separate rendered-page audit and laboratory performance measurements. SSPS, SSPS+ and PERF answer different questions.
  • Observed AI citations of a page, which require measured answers and are not predicted by its local score.
  • Competitor comparisons in the same measured question set. A first audit is a snapshot; recurring measurements require a paid plan.

Permissions

  • Installation requests activeTab, storage, scripting and access to platform.supasaito.com. It does not grant standing access to every website.
  • Standing access to your own domains is granted per domain after you sign in, from a list you can see.
  • Any grant can be revoked at any time from the browser’s extension settings.

Privacy

Local checks do not upload page content. The popup contacts platform.supasaito.com to check sign-in status. Signed-in lookups on allowed brand domains send the current origin and path; query parameters and fragments are stripped first. See section 6-3 of the privacy policy for processing and storage details.
