SEO Readout: On-Page SEO, Schema & SERP Check

SEO Readout reads the page you are on and tells you, in plain words, what is right and what is wrong with it for search. One click, one score, quick wins first. Click any finding and the page scrolls to the element and outlines it. WHAT IT CHECKS • Title and meta description: length in characters and in pixels, the way Google actually cuts them, plus duplicates and placeholders. • Headings: one H1, no skipped levels, nothing hidden, the full outline as a tree. • Images: missing alt, placeholder alt, missing width and height (layout shift), a lazy-loaded hero. • Links: every link on the page with its anchor text, internal or external, nofollow, sponsored and ugc, and where it sits (menu, body, footer). Flags links with no text, "click here" links, nofollow on links to your own pages, and http links on an https site. Filter them, click one to see it on the page, copy the lot as CSV. Links are read, never visited. • Canonical: missing, relative, pointing elsewhere, http on an https page. • Indexability: robots meta, the X-Robots-Tag header, and robots.txt for the URL you are on. Most extensions miss the header. A noindex page gets a banner across the top so you cannot miss it. • Structured data: every JSON-LD block is parsed, and each item is checked for the properties Google needs before it will show a rich result. Broken references, badly formatted dates and relative links are caught too. • Social sharing: every Open Graph and X card tag with its fallback, and a preview of how the link card will look when it is shared, with the real image loaded and its size checked. • SERP preview: the Google result on desktop and mobile, with the title and description editable so you can try a rewrite and watch the width meter. • Before JavaScript: the page is fetched again as plain HTML and set beside what the browser shows, so content that only appears after a script runs is flagged. Many AI crawlers read the HTML alone. • AI crawlers: whether the site's robots.txt lets AI crawlers onto the page, one row each, with the rule that decided it. • Local details: the business name, phone and address in the structured data, matched against what the page shows. It catches a phone number the page never prints, and a call link that dials a different number from the one it displays. THE SCORE Four areas are each scored out of 100, then weighted into one overall number with a grade. Fails cost more than warnings. Passing checks are folded away so the first thing you see is what to fix. Quick wins, the one-line changes, come first. EXPORT Copy the whole report as Markdown for a ticket or a client email, as JSON, the heading outline as text, every link as CSV, or the score card as a PNG for Slack. WHAT IT WILL NEVER DO • Send page content, URLs or anything else to a server. Every check runs inside the popup. • Ask for an account, a login or a licence key. There is no paid tier. • Open a tab on install, on update, or ever. No changelog pop-ups, no donation asks. Safe to open in front of a client. • Ask for permission to read every site. It runs on the tab you click it on, and only then. Four requests leave the popup, all made by the page to its own site: a HEAD of the current URL to read X-Robots-Tag, a GET of the same URL to read the HTML before JavaScript runs, a GET of /robots.txt and a GET of /llms.txt. Nothing leaves the site you are already on. WHO BUILT IT Newcastle Web Co, a web design and SEO studio in Newcastle, Australia. We built it because we wanted one, and the free ones either nagged, phoned home, or stopped at listing what was there without saying whether it was right.
