URL metadata, also known as link metadata, refers to data that is embedded within a URL or hyperlink. This metadata contains information that describes the target webpage or resource that the link is pointing to. URL metadata can include details like the page title, description, author, publication date, and more.
When you share a link on social media or embed it into a web page or document, the accompanying URL metadata allows the title, description, and other details about the target page to be automatically populated. Rather than showing the raw URL, URL metadata enables a preview of the destination content to be generated when the link is shared or embedded.
URL metadata serves multiple purposes:
Provides Context For Links
URL metadata gives context to bare hyperlinks. Without metadata, a raw URL like “https://example.com/page1” doesn’t provide any information about where the link leads. The metadata embeds details about the target page so users have some preview of where they will end up if they click the link.
Improves Clickthrough Rates
Because URL metadata generates a preview, users are more inclined to click on links. They can see where the link is pointing them to rather than blindly clicking on bare URLs. Providing a title, description, and image through metadata results in higher clickthrough rates compared to raw links.
Enhances Social Sharing
When sharing links on social networks, URL metadata allows the link preview with title, description, and images to be automatically fetched and displayed. This gives your shared links more eye-catching and engaging previews on social media. Without metadata, your links would simply show the bare URLs when shared.
Aids Search Engine Crawlers
Search engines like Google rely heavily on URL metadata when crawling and indexing websites. The metadata provides important clues for search engine bots to better understand the content on pages that links are pointing to. Optimized URL metadata can help pages get indexed faster and ranked better in search results.
How is URL Metadata Generated?
There are two main ways URL metadata can be generated:
1. Automatically from Webpage Content
When you share a link to a webpage, most social networks and messaging apps will automatically scrape the page to extract the metadata. The title tag, meta description, and images on the page will get pulled into the link preview.
For example, if you share a link to https://www.example.com which contains the following metadata:
<title>Example Website</title> <meta name="description" content="This is an example website. Welcome!">
The shared URL preview will automatically display “Example Website” as the title and “This is an example website. Welcome!” as the description.
The social network generates the preview by scraping the metadata from the page when the URL is shared. This happens automatically behind the scenes.
2. Manually Embedded Metadata
URL metadata can also be manually generated and embedded into the link code. This involves adding specific metadata tags when creating the hyperlink code.
For example:
<a href="https://www.example.com" title="Example Website" data-description="This is an example website. Welcome!"> Visit the Example Website </a>
Here the title and description have been manually added as metadata attributes in the anchor tag. This embedded metadata will be used when generating previews for this link.
Manually adding metadata gives you more control compared to relying on automatically scraped data. You can optimize the metadata text to be appealing for users who see the link preview.
What Information Can Be Included in URL Metadata?
Here are some of the key details that can be specified in URL metadata:
Title
The title of the target webpage. Usually extracted from the <title> tag on the page. Ideal length is 55-60 characters.
Description
A concise summary of what the page is about. Typically sourced from meta description tags. Ideal length is under 200 characters.
Images
Preview images displayed with the link. Automatically extracted or specified through metadata tags.
Author
Name of the content creator. Derived from author meta tags.
Publisher
Name of the site or company that published the page. Based on publisher meta tags.
Publication Date
The date the content was published, sourced from relevant metadata tags.
Best Practices for Optimizing URL Metadata

Duplicate Content
Using identical metadata across multiple pages on a site can confuse bots and trigger duplicate content penalties from search engines.
Overly Promotional
Link previews should inform the user, not sell to them. Avoid hype-filled salesy metadata that provides a bad user experience.
Irrelevant Images
Pulling arbitrary thumbnail images rather than representative pictures makes previews less compelling for users.
Outdated Information
Make sure to update title, description, and other metadata when content changes to avoid misleading previews.
Metadata Stuffing
Jamming as many keywords into metadata as possible is seen as spammy behavior that can harm SEO and user experience.
