Ever wondered how old is a page on web? Want to know age of a webpage? When a page was first published? Surely Google Cache is not an answer because it shows the latest date and time, and NOT the date and time when it was first published. There are many tools, plug-ins and add-ons but none worked up to my satisfaction. So here is a quick solution -
1. Search the keyword or the page URL in Google.com
2. In the results, on the left panel, you will find "Any Time". Click any option there, say "past year"
3. Now Google will start showing date of publish below each search result.
