What it checks
Tags and launch mistakes
Title and description
A missing or placeholder title (“React App”), and no meta description for search results.
Social preview
No og:image, or one with a relative address that Facebook, LinkedIn and Slack can’t load.
Hidden from search
noindex in a meta tag or header, and robots.txt rules that block the page.
Canonical and staging
A canonical pointing at another site or staging, and links still going to localhost or staging.
Heading and favicon
No H1 on the page, and no favicon for tabs and bookmarks.
Certificate and domain
An HTTPS certificate about to expire, a domain registration running out, and mixed content.
Three steps, about 20 seconds

A live page, a staging link or a client preview.
- 2
We read it like a crawler
The page opens in Chrome; its tags, response headers, robots.txt and certificate are read.

Fix before launch
Each problem with what it costs you and the line to add or change.
Guide
The tags every page needs
- 01
Title and meta description
The<title>is the blue line in search results and the tab name: unique per page, about 50–60 characters. The<meta name="description">is the text under it: about 150 characters that make people click. Google may rewrite it, but without one it picks any text from the page. - 02
Open Graph for link previews
When someone shares your page on LinkedIn, Slack, WhatsApp or Facebook, the preview comes fromog:title,og:descriptionandog:image. The image needs a full address (https://…), and 1200×630px works everywhere. - 03
The launch mistakes that hide a site
Staging sites are often set tonoindexor blocked in robots.txt, and that setting goes live with them. A canonical tag still pointing at staging tells Google the real page is somewhere else. These cost all search traffic at once, so check them on the live address after every launch. - 04

Questions
How long should a title and meta description be?
Keep the title tag to about 50–60 characters (roughly 580px in Google’s results) and the meta description to about 150–160 characters. Longer ones are cut off with “…”. This checker reports a missing or placeholder title and a missing description; count the length in your editor or CMS.
Does it work as an Open Graph and noindex checker?
Yes. It reports a missing og:image or one with a relative address that link previews can’t load, and a page hidden from search by a noindex meta tag, an X-Robots-Tag header or robots.txt.
Does it check headings?
It reports a page with no H1 heading. The full accessibility check also finds fake and empty headings.
Does it check robots.txt?
Yes. It reads the site’s robots.txt and reports when its rules block the page you checked, along with noindex in a meta tag or the X-Robots-Tag header.
Why does it say noindex isn’t a problem on my staging site?
Hiding staging from search is right. noindex and robots blocks are reported on live addresses; on a project, you can name your live and staging addresses so each is judged correctly.
Is this an SEO audit?
No. It catches the launch mistakes that stop a page being found or shared properly, not keyword or ranking advice.
Do I need an account?
No. You can run a few free checks without one. Your result has a private link that we never list or index.
