🏷️Metadata Analysis Explained
Everything about title tags, meta descriptions, Open Graph, canonical URLs, and SERP previews — the 10 checks that make up your metadata score.
Metadata is the first thing search engines and social platforms read about your page. Hugo's metadata category runs 10 individual checks with a combined weight of 20% for main pages and 25% for subpages — making it one of the most influential categories for your overall score.
Title Tag
The title tag is the most critical on-page SEO element.[1] It appears in search results, browser tabs, and social shares. Hugo checks both presence and length.
Title Length (characters)
Meta Description
While meta descriptions aren't a direct ranking factor, they significantly impact click-through rates from search results.[3] A well-crafted description can be the difference between a click and a scroll-past.
Description Length (characters)
Canonical URL
The canonical tag tells search engines which version of a page is the "official" one. This prevents duplicate content issues when the same content is accessible via multiple URLs (e.g., with/without www, HTTP/HTTPS, URL parameters).[4]
Every page should have a self-referencing canonical URL. Use the full absolute URL including the protocol (https://).[4]
Open Graph Tags
Open Graph (OG) tags control how your page appears when shared on social platforms like Facebook, LinkedIn, and Twitter.[5] Hugo checks for the four essential OG properties: og:title, og:description, og:image, and og:url.
OG Tags (tags)
Other Metadata Checks
| Check | What It Looks For | Impact |
|---|---|---|
| Twitter Card | twitter:card meta tag for Twitter-specific previews | Low |
| Viewport Meta | width=device-width, initial-scale=1 for mobile responsiveness | High |
| HTML Language | lang attribute on <html> element for accessibility and SEO | Medium |
| Favicon | Any icon link in the document head | Low |
| Character Encoding | UTF-8 charset declaration | Medium |
| SERP Preview | Visual preview of how your page appears in Google results | Info |
