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 Tag Length
Too Short
Optimal
Truncated
< 3030–60> 60characters

Title Length (characters)

Good
30–60 characters
Warning
<30 or >60 characters
Poor
Missing entirely
Google typically displays 50–60 characters.[2] Titles under 30 characters miss keyword opportunities, while titles over 60 get truncated in search results.

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.

Meta Description Length
Too Short
Optimal
Truncated
< 120120–160> 160characters

Description Length (characters)

Good
120–160 characters
Warning
<120 or >160 characters
Poor
Missing entirely
Google shows approximately 150–160 characters on desktop.[3] Descriptions under 120 characters may not convey enough information to attract clicks.

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]

💡Best Practice

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)

Good
All 4 present
Warning
1–3 present
Poor
None found
At minimum, include og:title and og:image for compelling social previews.[5] Missing OG tags mean platforms generate their own previews which are often poor quality.
