How to Check When a Website Was Last Updated


Each method has its own advantages and complexities. In this guide, we’ll walk you through seven different ways to determine the last update date of a website.


1. Using HTTP Header Checker to Find the Last Modification Date


HTTP headers contain valuable information about server requests and responses, including the ‘last-modified’ header, which shows the date and time a webpage was last changed.


Steps to uncover it:


  • Visit an HTTP Header Checker tool like SEOmator’s Free HTTP Header & Status Code Checker.
  • Enter the URL of the webpage you want to inspect and click ‘Submit’.
  • The tool will display various information, including the ‘last-modified’ date.


2. Checking Source Code for the Last Updated Date


The source code of a website is its blueprint and may contain the date of the last update. However, not all websites include this information in their source code.


Steps to view the source code:


  • Open the webpage you want to check.
  • Right-click on the page and choose ‘View Page Source’ or ‘Inspect’
  • Press Ctrl+F (Command+F on Mac) to open the search box and type ‘Last Modified’.
  • Look for a line similar to <meta name=”Last-Modified” content=”2021-04-22T07:30:04Z” />. The date in the content section is the last modified date.


3. Checking the Sitemap for Last Update Date


A sitemap serves as a roadmap for a website, often containing the last modified dates for each page. This method requires more technical know-how but is very effective.


Steps to check the sitemap:


  • Enter the sitemap URL into your browser’s address bar and press Enter. If you don’t know the sitemap URL, you can find it using SEOmator’s free sitemap finder tool.
  • Look through the XML file for ‘lastmod’ tags. The dates listed adjacent to these tags signify the most recent updates made to each webpage.


4. Utilizing Google Search to Verify the Last Modification Date


Google’s search results can sometimes provide the last modified date based on its indexing.


Steps to use Google Search:


  • In the Google search bar, type “” (replace ‘’ with the actual URL).
  • Look at the snippets under each search result. Occasionally, you’ll find a date there indicating when the page was last updated.


5. Checking Command URL for Last Update Date


Some websites, especially those using Apache servers, allow access to server information, including ‘Last Modified’ dates.


Steps to check the command URL:


  • Add /?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 after your URL.
  • If the website is using Apache, a page will appear showing the ‘Last Modified’ date.


6. Checking Google Cache for Last Update Date


Google’s cache provides a snapshot of a webpage as it appeared the last time it was visited by Googlebot.


Steps to use Google Cache:


  • Go to Google’s cached page by entering in the search bar, replacing with the URL you want to check.
  • At the top of the page, you’ll see a note like ‘This is Google’s cache of It represents a snapshot of the page as it appeared on [date]


7. Checking Internet Archive for Last Update Date


The Internet Archive’s Wayback Machine takes snapshots of web pages over time, showing when a page was updated.


Steps to use the Wayback Machine:


  • Visit The Wayback Machine.
  • Enter the website’s URL.
  • Browse the timeline of snapshots—these dates indicate when the site was updated.
  • By using these methods, you can accurately determine the last updated date of any website, ensuring the information you rely on is current and reliable.


Using Online Tools

  • Wayback Machine: This tool allows you to view the history of a webpage. By checking the dates of the snapshots, you can infer the update history.


  • Google Cache: Enter “cache:[website URL]” in Google. The cached version may include the date when Google last indexed the page.


  • SEO Tools: Tools like Ahrefs or SEMrush often have features that indicate the last updated date of the content.


Checking for Update Notifications


Some websites explicitly mention their update schedules or have sections dedicated to news and updates.


  • News Sections: Check if the website has a blog or news section where updates are posted.


  • Announcements: Look for an announcement bar or section on the homepage that details recent changes or updates.


Why Is It Important to Keep a Website Up to Date?

  • User Trust: Regular updates show users that the site is actively maintained, increasing their trust.

  • Misleading Dates: Some sites might display the last updated date inaccurately or for SEO manipulation.


  • Inconsistent Updates: Websites with multiple sections might update some parts frequently and others rarely, leading to mixed signals.


How to Use Search Engine Tools to Locate the Last Updated Date of a Website


Search engines can be powerful allies in determining the last updated date of a website.


  • Google Search: Use advanced search operators. Enter “inurl:[website URL]” and set the date range to find the latest indexed version.


  • Bing Webmaster Tools: Similar to Google, Bing’s tools can provide insights into when their bots last crawled a site.

  • Enter the URL: Input the URL of the website you want to check.


  • Analyze the Results: The tool will provide data on the last known update date, among other site details.


How to Analyze the Content of a Website to Know the Last Update Date


Sometimes, manually analyzing the website’s content can reveal the last update date.


  • Look for Timestamps: Articles, blog posts, and news updates often have timestamps.


  • Review the Content: Compare different parts of the site. Frequently updated sections like blogs or news pages might indicate recent activity.


  • Check Comments and Social Shares: The dates of comments or social media shares can also give clues about the last updates.


Common Mistakes People Make to Know a Website’s Last Updated Date


  • Relying Solely on the Footer: While the footer might show a date, it’s not always accurate for content updates.


  • Ignoring Cached Data: Cached versions can provide more accurate update timelines.


  • Not Using Multiple Sources: Depend on various tools and methods for a comprehensive view.


How to Avoid These Mistakes?


  1. Cross-Verify: Use multiple methods to check the last updated date.
  2. Use Reliable Tools: Stick to trusted online tools and SEO platforms.
  3. Stay Updated: Regularly check your own website’s updates and ensure they are accurately reflected.
