About

Timestamped helps you find the likely publication date of the web page you are currently viewing.

Many articles, blog posts, product pages, documentation pages, landing pages, and online resources do not show a clear publication date. Sometimes the date is hidden in metadata. Sometimes it is included in structured data. Sometimes it appears in a time tag, inside the page source, in the URL, or in an archived version of the page. Timestamped brings these clues together and gives you a simple estimate of when the page was likely published.

The extension is designed for people who need quick context while browsing the web. Whether you are reading an article, checking a source, evaluating a blog post, researching a topic, reviewing SEO content, or trying to understand whether a page is recent or outdated, Timestamped gives you a faster way to inspect the page’s date signals.

What Timestamped does

Timestamped analyzes the current page and looks for common signals that can indicate a publication date, including:

• Metadata used by publishers and content management systems
• Structured data such as schema.org Article, BlogPosting, NewsArticle, and related formats
• HTML time tags and visible date elements
• Open Graph and social sharing metadata
• URL patterns that may include a year, month, or full date
• Page source clues commonly used by blogs, news sites, documentation sites, and marketing pages
• Archive information from the Wayback Machine when available

The result is not presented as a guaranteed official publication date. Instead, Timestamped gives you a likely publication date based on the evidence it can find. This is important because many websites use different date fields for different purposes. A page may have a published date, a modified date, an indexed date, a copyright date, or a date embedded in the URL. Timestamped helps you compare these signals and understand the most likely answer.

Why this is useful

Knowing when a page was published can change how you interpret it.

A medical article from ten years ago may no longer reflect current guidance.
A software tutorial may be outdated if the library or framework has changed.
A product review may be less useful if it was written before a newer version launched.
A news article may be missing context if it is old but appears in search results today.
A landing page may look fresh even if the underlying content has not changed in years.

Timestamped helps you avoid guessing. Instead of manually opening developer tools, reading the HTML source, searching for hidden metadata, checking URL structures, or visiting archive pages, you can click the extension and quickly see the available date clues.

Who it is for

Timestamped can be useful for:

• Researchers checking the freshness of online sources
• Journalists and editors verifying article context
• SEO professionals auditing old or undated pages
• Content marketers reviewing publication and update signals
• Students evaluating whether a web source is current
• Developers checking documentation pages
• Product managers reviewing competitor pages
• Analysts collecting web evidence
• Anyone who wants to know whether a page is recent, old, updated, or difficult to date

It is especially useful when a page does not clearly display a date but still contains hidden signals in its source code.

How it works

When you open a page and click Timestamped, the extension scans the page for date-related information. It checks several possible sources instead of relying on only one field. This makes the result more useful across different kinds of websites.

For example, a news site may include a publication date in structured data.
A blog may include a date inside a visible time tag.
A documentation page may include a modified date in metadata.
An older website may include the date in the URL.
A page with no visible date may still have an archived snapshot in the Wayback Machine.

Timestamped combines these signals into a simple interface so you can quickly understand what date information is available.

Best-effort date detection

Timestamped is a best-effort tool. It cannot guarantee that every date found on a page is the original publication date. Some websites remove publication dates, overwrite them with updated dates, use incorrect metadata, or include unrelated dates in the page source. Other websites dynamically load content, block automated checks, or provide incomplete markup.

Because of this, Timestamped is most useful as a fast research assistant, not as a final authority. It gives you a likely publication date and helps you see the evidence behind that estimate. When accuracy is critical, you should still compare the result with the page content, the publisher’s own information, and other external sources.

Common use cases

Check if an article is still relevant
Before citing or sharing an article, use Timestamped to see whether it appears to be recently published or several years old.

Evaluate sources for research
When collecting online sources, quickly check publication clues without manually inspecting the page source.

Audit website content
If you manage or review a website, Timestamped can help identify pages with missing, unclear, or outdated date signals.

Understand SEO and content freshness
SEO professionals can use Timestamped to inspect how publication and modification dates appear in metadata and structured data.

Review technical documentation
Software documentation often changes over time. Timestamped can help you understand whether a page may be old, recently updated, or missing date information.

Investigate undated pages
Some pages intentionally or unintentionally hide dates. Timestamped helps surface hidden clues that may still exist in metadata, structured data, URLs, or archives.

Simple and focused

Timestamped is intentionally focused on one job: finding likely publication dates. It is not a full SEO suite, crawler, analytics platform, or content management tool. It is a lightweight browser extension for quick, page-level date inspection.

Open the page.
Click the extension.
Review the likely date and supporting clues.

That is it.

Important limitations

Timestamped may not always find a date. Some pages simply do not include useful date information. Some pages block access to certain data. Some websites use JavaScript-heavy rendering or unusual markup that makes date detection harder. The Wayback Machine may not have archived every page, and archive data may not represent the original publication date.

In some cases, multiple dates may appear on the same page. For example, a page may include:

• Original publication date
• Last modified date
• Copyright year
• Comment date
• Product release date
• Event date
• Archive date
• Date inside a URL

Timestamped attempts to identify the most likely publication date, but users should treat the result as an informed estimate.

Privacy-conscious by design

Timestamped is built for a narrow purpose: helping you inspect date signals on the current page. It does not exist to track your browsing behavior, build a profile about you, or replace your search engine. Its purpose is to make page date discovery faster and clearer.

When archive data is checked, the current page URL may be used to query archive availability. This is necessary for Wayback Machine-style date discovery. The extension focuses on the page you are actively inspecting.

Why publication dates are often hard to find

The modern web is inconsistent. There is no single universal standard that every website follows when showing publication dates. Some publishers display the date clearly at the top of the article. Others hide it in structured data for search engines. Some only show a last updated date. Some include a date in the URL but not in the page. Some remove dates entirely to make content appear evergreen.

Timestamped helps by checking multiple possible locations at once. Instead of assuming that one missing date means there is no date, it looks deeper.

Examples of pages where Timestamped may help

• News articles without visible dates
• Blog posts with hidden metadata
• Old marketing pages
• Product announcements
• Documentation pages
• Help center articles
• Research pages
• Archived web pages
• SEO landing pages
• Company updates
• Tutorials and guides
• Evergreen content pages

A small tool for better context

The date of a page is a small detail, but it often matters. It helps you judge relevance, reliability, freshness, and historical context. Timestamped gives you a quick way to uncover that detail when the website does not make it obvious.

Use Timestamped whenever you ask:

When was this page published?
Is this article old or new?
Can I trust this source as current?
Was this content updated recently?
Is there a hidden date in the page metadata?
Does the URL reveal a date?
Does the Wayback Machine have an earlier snapshot?

Timestamped makes those questions easier to answer while you browse.
