Metadata completeness
The title, description and canonical URL are how an agent sums up a page and spots duplicates before reading it.

What it checks
The extension reads the page’s <head> in your browser and looks for four
things:
- a non-empty
<title> - a non-empty
<meta name="description"> - a
<link rel="canonical"> - an Open Graph title or description (
og:titleorog:description)
A missing title or description is treated as more serious than a missing canonical or Open Graph tag, because those two are what an agent uses to decide what the page is before reading it.
Results
| Status | When |
|---|---|
| Pass | All four are present |
| Warn | The title and description are present, but the canonical or Open Graph metadata is missing |
| Fail | The title or the meta description is missing |
| Unmeasured | The extension could not read the page (open it in the active tab) |
The result names exactly which items are missing.
How to fix
Add whichever items the result lists to the page’s <head>:
<head>
<title>Blue running shoes | Example Store</title>
<meta name="description" content="Lightweight blue running shoes for road and trail." />
<link rel="canonical" href="https://example.com/shoes/blue-runner" />
<meta property="og:title" content="Blue running shoes" />
<meta property="og:description" content="Lightweight blue running shoes for road and trail." />
</head>Point the canonical at the preferred URL for the content, so an agent that reaches the same page through several URLs can tell they are one page.
